Worcester Greenstar 25I Review

Though Worcester Boilers have been around for quite some time, the 25i wasn’t a flagship boiler range until 2015 when Worcester made the junior range. The ‘Junior’ range included the 24I. However, this range has since been replaced by the 25i.

In this piece, we shall review the Worcester 25i, including price and size.

Price and cost of installation

Now, the Worcester brand provides premium boilers. As such, you expect their boiler prices to be competing with other premium boiler brands like Valliant and Baxi.

You should expect to pay about £950 for the boiler only. This means that if you need a timer, flue, and extensions during installation you’ll incur extra costs. During installation, you will incur about £2100 by a Gas Safe boiler engineer.

Note: the exact price depends on the materials needed and the Complexity of installation based on the location of installation.

Before you proceed further, it’s important to decide whether this is the right size for your home. The Worcester 25i can serve a three-bedroom house with low hot water and heating needs. The ideal properties are those with one shower and two bedrooms. Such properties include small apartments, a two-bedroom terrace house and a flat.

If your house has three bedrooms, more than ten radiators and more than three showers, you will need a bigger boiler to the Worcester 25i. The next best size is the Worcester 30i, and a larger option is the Ideal Vogue C40.

Service and Maintenance

If there’s one thing that most boiler installers agree on is the fact that Worcester boilers are harder to install and service. Because of this, the servicing costs are high in comparison to other boiler brands.

Over the years, this is something that Worcester engineers have worked on – they have made it easier to access boiler components. In addition to this, the panel is detailed and has numerous boiler faults. With these boiler faults, a Gas Safe engineer can diagnose the boiler on the phone and in the process save costs.

Frozen pump and condensate pipe

The main reason Gas Safe engineers are called out to fix the Worcester 25i include frozen condensate pipes and faulty pumps. When wastewater freezes and blocks these crucial components, the 25i lockout and stops working. To help prevent a frozen condensate pipe, Worcester 25i comes with a CondenseSure  Siphon. With this siphon, you will have an easier time during winter.

Display panel

A huge turnoff for many homeowners about the 24l Junior is the fact that it lacked functionality and the display was ugly and didn’t help to fix some of the problems easily.

But now, Worcester has added to the functionality of the 25i. Now, users can adjust the heating and water temperature on the panel without using a thermostat.

And even better, the boiler displays relevant fault codes which make it easier to diagnose problems.


Like other Worcester boilers, the 25i boiler range comes with a standard 5-year warranty. Homeowners can extend the warranty by a year when they install a magnetic filter system. However, to qualify for this extension, the filter should be a product by Worcester.


The common control that you can use with the Worcester 25i is Worcester Wave. This boiler is smart, heating control, and has Wi-Fi power. With these features, you can adjust heating through the Wave App.

The control costs more than  £180. If the cost is too high, request the Gas Safe engineer to suggests great alternatives.


If you are low on space, you should consider the Worcester 25SI Compact. Otherwise, the 25i is a great option based on its user-friendliness and functionality.

Benefits of a Boiler Service

If you would want to prevent your boiler from breaking down when you most need it, you should conduct a regular annual boiler service. Though most boiler manufacturers pay attention to quality, over time, boilers accumulate dust and debris, which makes them less efficient and prone to breakdowns. Because of this, you must hire a Gas Safe boiler engineer to service your boiler.

Below are some of the benefits of the annual boiler service

It helps to prevent a boiler breakdown

For a moment, think of your boiler as the engine of a car. Cars need to have regular maintenance and servicing after travelling a specified distance to ensure that it operates at optimum efficiency especially when travelling over long distances.

Unlike cars, most boilers don’t get downtimes – they run 24/7. This makes the annual boiler service and maintenance even more important. The inspection and service will also improve the lifespan of the boiler.

Improving boiler efficiency

If you want to save money on energy bills, you should have your boiler serviced regularly. When the boiler components are working at the optimum, it will translate to the entire system and the overall efficiency.

Maintaining boiler efficiency includes doing simple things like cleaning the system through a chemical flush or Powerflush. This allows the system to run smoothly and transfer maximum heat.

Keep the boiler safe

A properly maintained boiler does not only run efficiently, but it is also safe. Boilers usually come with built-in safety mechanisms to ensure that they run correctly. However, the parts ensuring this safety can wear out with time and lead to boiler breakdowns. Part of boiler safety includes ensuring the fan is operational, and that the condensate and flue pipes are clear.

Also, for maximum safety, you should use a Gas Safe engineer to conduct the service safely as well as legally.

The boiler servicing checklist

  • The Gas Safe engineer will inspect the boiler controls to ensure they are working safely. Moreover, they will turn on the boiler to see if they can pick up on any faults.
  • The inspection also includes checking the insides of the boiler for leaks and corrosion.
  • The engineer will remove the boiler casing to inspect the boiler components, including the sensor probe, main injector, the burner, and the heat exchanger.
  • They will inspect the gas pressure to ensure it lies within the acceptable green zone. Anything lower or higher means there’s an underlying boiler problem.
  • They will conduct a flue test to ensure that it’s not blocked and that its components are safely sealed to prevent harmful boiler gases from leaking into the house.
  • The gas valve is adjusted to ensure the burner is combusting efficiently.
  • The boiler parts are cleaned as needed.
  • The gas components are tested for leaks and cracks.
  • The boiler casing is replaced and sealed.

When the Gas Safe engineer completes the service, he will offer an annual service certificate. This certificate acts as proof of service when your insurance company comes asking for it. We advise holding onto service certificates dates two years back.

We cannot stress enough the importance of hiring a Gas Safe engineer. First, they ensure safety, and second, they help you maintain your boiler warranty. Using any other company or individual voids the warranty and leave you to fend for yourself in case of a boiler emergency.

Where Should I Put My Boiler?

For many homeowners, when they are looking to have a new boiler installed, they prefer to install it in the place where the old boiler was. However, if the new boiler is a bigger or a different type, this isn’t always possible. Also, in some instances, homeowners want to change things up. But this is easier said than done especially because there are boiler installation regulations to be followed.

To help make it easier for you, below is a quick guide of where you can install your boiler and be assured of efficiency and safety.

Choose a wall location

First and foremost, the boiler should always be installed on a wall that is strong enough to support its weight. Usually, this is the external wall since they are made the strongest in comparison to divider walls in the house. With a strong wall, you are assured the boiler will not become loose with time and pour hot water around the house.

Additionally, you’ll also need to let the flue pass to the outside of the house easily. This is easily done when the boiler is installed on the external wall. Flue location and clearance is covered in the building and boiler installation regulations. The regulations define a minimum distance the flue should be installed from air bricks, windows and other building outlets. This regulation is necessary to ensure the harmful gases don’t find their way back into the house.

Another important consideration to be made is the installation of the condensation pipe. This pipe carries waste and acidic water from the boiler into the drainage system. Given that it drains into the main drainage system, it should be located outside the house. And to prevent the wastewater from freezing during winter, it’s essential to insulate the pipe.

Easy access

Though boilers are made to last long, they can last even longer with regular maintenance and servicing. Because of this, you need to install the boiler in a location that it will be easier for the Gas Safe engineer to access it for maintenance. The engineer should access all parts of the boiler without having to assume awkward and harmful positions.

You can install the boiler inside a cupboard provided it’s big enough for a Gas Safe engineer to reach various parts. Because of this, a walk-in bedroom cupboard will work just fine. But with bedroom boiler installations, you need to install a carbon monoxide detector. Carbon monoxide is a by-product emitted by a running boiler. It is colourless and odourless. Over the years, it has been responsible for the death of some homeowners. To improve your safety, this detector is essential.

Also, depending on the nature of your property, you can install the boiler in the outhouse o garage. But for these locations, you’ll want extra boiler protection against the cold.

And last but not least, you can place the boiler in the kitchen or the bathroom. However, there are still some regulations regarding wiring that you need to adhere to. These regulations help to protect the boiler and wiring from moisture and steam.

If you intend to install the boiler in the loft, you need to ensure the loft is accessible and is well lit for safety.


Always choose a Gas Safe boiler engineer to install your boiler. This way, even if you are unsure of the finer installation details, they will guide and ensure boiler installation regulations are met.

How to Keep Your House Warm During Winter

As the temperatures drop this winter, there are steps you can take to ensure you cut back on your spending on energy bills and to keep you warmer. This goes beyond replacing old and broken windows and increasing your home’s insulation. Below are some of the best ways to keep your home warmer during winter.

Boiler servicing

Boilers are designed to last for ages. Heck, they can last for about 10 – 15 years depending on the type, use, maintenance and servicing done over the years. Boiler experts recommend servicing your boiler once every year. This service checks on the boiler components and ensures they are in good condition. It also helps in improving efficiency and fixing small problems before they escalate into major problems.

But the thing with boiler services is that they have to be done by registered Gas Safe engineers. These engineers will offer a certificate after the inspection to act as proof in case your insurance company requests for proof of annual servicing. Also, using a registered gas engineer helps in retaining your boiler warranty.

A boiler that is in good working condition is efficient and will keep your home warm effortlessly.

Close the curtains

You’ll be surprised at the amount of heat that is lost through your windows. If you have curtains, you should close them before darkness creeps in. Or if you are away, you can keep the curtains closed to retain the heat that has built up during the day.

And if you can afford it, you can get some thermal curtains.

Use your oven to heat the house

We do not advocate for using house appliances for functions they are not designed for. This is to mean that your boiler should stick to heating your home and your oven to baking sumptuous cakes and meals.

However, once you are done, you can leave the oven door open and allow the heat to radiate into your room. It will help raise the room temperature faster, and as such, it will help you save on energy bills. However, you need to ensure the kids stay away from the open oven to prevent accidents.

Install a rug

Wooden floors look great and elevate the beauty of a home. But in winter, they work against you by letting heat escape right through them. Placing a rug on the floor will help you reduce the heat loss and keep your feet warm throughout winter.

Determine your ideal room temperature

Most homeowners usually turn the thermostat to the highest temperature setting in the hopes that the boiler will heat the house faster. Unfortunately, that’s not how boilers and thermostats work. The thermostat setting dictates how high the boiler will heat your home. Once this temperature is achieved, the thermostat will signal the PCB which will then turn off the boiler.

Knowing your ideal temperature will help you enjoy ideal comfort in your home. The best temperature is between 18 and 21 degrees Celsius. Anything lower or higher than this range will either leave your home colder or waste energy.

If you can afford it, you should install a smart thermostat. These thermostats allow users to control temperature settings remotely through apps installed on tablets and smartphones. Overall, you’ll save more energy and still enjoy your home at just the right temperature.


Keeping warm during winter is crucial as it will help you keep opportunistic diseases at bay and increase your comfort levels. The above tips are simple and quite affordable. Feel free to get creative with their implementation.

Ideal vs Viessmann Boilers, Which Brand to Choose?

Viessmann and Ideal boilers are among the top 5 boiler brands in the UK. And with the level of competition in the UK boiler industry, this is a significant achievement. It only means that they are doing something right ad at the very least keeping up with changing boiler technology to offer the UK home and business owners the best possible service.

If you are in search of a new boiler, you are wondering which one is best for your needs between Viessmann and Ideal boilers. Well, from face value, they both seem to offer the same thing. But a more in-depth look discloses some differences that will help you make an informed decision.

Ideal and Viessmann Boilers

Aside from being one of the best boiler companies in the 21st century, Ideal and Viessmann boilers have a long and rich history in the boiler industry. Ideal Boilers was created in 1906 while Viessmann was established in 1917. They each currently have over a century of experience under their belt. With their experience, they understand the customer needs and have the knowledge and skills to meet those needs.

They each started as small companies and have grown to be beasts employing thousands of workers across the globe. They have won individual trophies and awards for their exemplary service. For instance, Viessmann Boilers have won:

  • The Number 1 Trade Partner
  • iF Product design award
  • The Red Dot Award: Product Design

Ideal and Viessmann Boilers Comparison Review

To help you see the difference between the two companies, we must compare specific boilers from both companies. The boilers we’ve chosen are on the same performance levels and offer the same output – Ideal Vogue Combi vs Viessmann Vitodens 100-W.

The two boilers go for about the same price. The Ideal Vogue Combi costs £1,144 while the Viessmann Vitodens 100-W costs about £1,063.

Note: these are boiler prices and don’t include installation fees and cost of extra parts and services.

The Vogue Ideal is a premium boiler which comes with a standard 8-year warranty. But if you have an Ideal system filter installed as well, the warranty is extended to 10 years. It’s also worth noting that the boiler comes with a:

  • 5” backlit and full colour LCD
  • Simple pressure gauge
  • Compact design
  • Energy Saving Trust endorsement
  • LPG conversion
  • Stainless steel heating exchanger

On the other hand, the Viessmann Vitodens 100-W is compact enough to save space. It also has:

  • Heating seasonal efficiency of 94%.
  • Patented heat exchanger technology.
  • Low noise design.
  • User-friendly controls through the backlit LCD.


So which is better between the two? Though they each have a stainless steel heat exchanger, the Viessmann Vitodens is better owing to the new patented technology. The Viessmann heat exchanger is made from a high-quality type of steel, i.e. Inox.

With this material, the heat exchanger will last longer, offer higher efficiency and be even more resistant to rusting. And given that the heat exchanger is more like the engine of the boiler, you can only imagine how long the boiler will last.

How Long does it Take to Fit a Boiler?

Winter is coming, and you need to prepare yourself for the chilling cold it comes with. Ensure you ready your boiler to keep your house warm throughout the cold season. Whether you need to install the first boiler in your quarters, add a new one, or replace an existing boiler; this guide is all you need to get the task done, hassle-free.

Here are 3 scenarios that determine the time you require to set up your boiler fully.

Straight boiler swap

A straight boiler swap is also called like-to-like boiler replacement. It involves switching a broken boiler with a similar type of boiler in the same location.

Time required

A like-to-like swap is the fastest type of boiler installation as the boiler goes into the same location, uses the existing pipe-work, and set up is virtually the same as the previous boiler. Usually, this takes one day. However, you may require an extra half day if:

  1. The existing pipe-work doesn’t directly align with your new boiler.
  2. Your building’s regulations require you to upgrade the gas run when replacing your boiler.

Installing a boiler similar to your existing one in a new location

If you require a new boiler fitted in a new location, or you want an existing boiler moved to a different place in your house, the process will take a little longer than a simple boiler swap. If you need to move your boiler from the kitchen to the garage or basement, for instance, the boiler installation engineer will have to:

  1. Cap off the present gas piping.
  2. Install additional gas pipe-work to the new boiler position.
  3. Adjust segments of the existing pipe-work so that all radiators can heat up properly.

Time required

You’ll need 1.5 to 2 days to fit a boiler or shift an existing boiler in a new position in your house. Either way, the time required for this kind of boiler installation increases with the distance from your current boiler.

Boiler system upgrade

Updating a boiler system is more complicated than a simple like-to-like replacement or new boiler installation. It involves changing one type of boiler for another, more suitable option. Examples of boiler system upgrades include swapping a back boiler for a combi boiler, replacing a combi boiler with a system boiler, and switching from a system boiler to a combination type.

Time required

Updating a boiler system requires more work and time than the other two types of boiler installation. This is because the boiler specialist has to:

  1. Install a boiler cylinder and revise the pipe-work when upgrading from a combination to a system boiler.
  2. Take out the boiler cylinder and re-work the gas piping and central heating structure if you’re upgrading from a system to a combi boiler.
  • Fit a condense pipe from the new boiler to a drain if it isn’t a condensing boiler.

Typically, a boiler system upgrade takes between 2.5 to 3.5 days depending on the accessibility and complexity of appliances involved.

Usually, it takes 8 hours to 4 days to fit a boiler depending on the nature of your boiler installation.

How Huch Does Central Heating Cost per Hour?

Not every homeowner is keen on knowing the amount of electricity or gas they use every month. But even then, it’s wise always to check your monthly billing to ensure you haven’t been undercharged or overcharged by the energy supplier. Moreover, the moment you know how much energy you use every month, you’ll be in a better position to take intentional steps to reduce your usage and save on energy bills.

But before you can save energy or lean your monthly energy billings, you need to understand how much energy a boiler consumes every hour. The amount of energy a boiler uses depends on the efficiency, size and the number of hours it runs daily. Today, boiler sizes are measured using kilowatts (kW) and often range between 24 and 27 kW, 35 and 42 kW, and 28 and 34 kW. If you have a house with a single bathroom and 10 radiators, you should install a boiler between a 24 and 27 kW rating. On the other hand, a large house with more than 20 radiators and more than three bathrooms need a boiler that is between 35 and 42 kW.

So what is a kilowatt?

kWh is a unit of measuring energy. It shows the amount of energy that the boiler can use if it runs for an hour. This means that a boiler with a 1kW rating would use a single kWh if it ran for an hour.

Using this unit of measurement, it’s easier to calculate the amount of energy (gas or electricity) that the boiler uses and how much of the energy costs. For instance, if you have a 24 kW boiler, it means that it will use 24kWh every 60 minutes. It’s approximated that 1 kWh costs 3.8 pence. Doing some quick calculations, it only means that to run a 24 kW boiler for 60 minutes would cost 9 pence. And as pointed out earlier, this cost changes depending on the age and size of the boiler and the cost of energy in your region.

According to studies conducted in 2017, the average UK home consumed anything between 8000 and 17,000 kWh. This means that the average boiler costs are £1,123 for both electricity and gas. To learn how much energy consumes every hour, you can install a smart meter. Most companies and suppliers are more than willing to install this device at no extra cost.

How much gas should boilers use?

It can be difficult to quote specific figures. However, depending on the size of the boiler, you can use the boiler size to estimate. For instance, if you have a 34 kW boiler, it will use the same amount per hour. If it runs for 6 hours daily, it means the energy used is 204 kW (assuming it is operating at maximum efficiency. If it’s not, this figure will be higher even if the rooms are nor warm and comfortable enough)

The next time you receive your energy bill, read the energy usage breakdown. Generally, the energy bill during winter should be more than what you receive during winter. But if you don’t think the reason for the high bill is the change in season, contact the energy supplier for an explanation.

How Long Does a Boiler Last?

According to statistics, Combi boilers are by far the most installed boilers in the Nottingham and the U.K. This is because they are a combination of efficient water heaters and central heating boilers. In addition to saving space, these boilers help to deliver hot water to taps and showers in the house from the mains without pumping. When you take a glance at a Combi boiler, it’s easy to understand why many people are so taken by it. But now the question is, how long does a boiler last?

Well, the answer to this question is dependent on a couple of factors, which includes the quality of your appliance and, generally, how well you look after the boiler. Below is a quick guide to answer this and other questions.

The average lifespan of the Combi boiler

Though they are all efficient in their operation and saving on energy bills and space, they differ in terms of longevity and quality. You should be aware of this when you are searching the market for a new Combi boiler. You shouldn’t go for the cheapest model on the market just so that you can save money in the short term as you might end up spending a fortune in the long run.

Generally, you can expect a boiler to last for about 15 years or even longer if you get a high-quality boiler and perform regular servicing. Because of this, you should always be keen on the warranties manufacturers offer for their boilers. They can give you insight into how long the boiler can last.

Should Combi boilers be serviced?

Servicing your boiler will indeed cost you a pretty penny. However, it’s a worthwhile undertaking since it will save you money in the long run in terms of repairs and energy efficiency. Getting the system checked by a Gas Safe engineer once yearly will help in ensuring the boiler remains in tip-top condition. During a servicing session, the engineer will inspect the heat exchanger, seas and electrical connections. They’ll also check the boiler pressure and boiler parts for leaks and signs of rusting. Any damaged parts will be replaced before it causes other parts to fail, as well.

Fixing a Combi boiler

If the boiler fails suddenly or develops some noise, it doesn’t mean you should install a new one. Many boiler problems can be fixed. And shocking enough, most solutions are easy. Some of the quick fixes include;

  • Resetting the timer
  • Checking boiler pressure and bleeding radiators of filling it up
  • Resetting the boiler
  • Defrosting the condensate pipe
  • Increasing temperature settings

But if the Combi boiler is always breaking down, you should consider investing in a new one. The price of a new Combi boiler depends on the size and brand. As you get a new boiler, you should also factor in the price of installation by a Gas Safe engineer. A Combi boiler for a small house costs anything from £600 – £1,500. For a semi-detached house, expect to spend anything from £700 – £2,000.

Cost of Installing Central Heating

It is surprising to learn that some UK homes still use old-fashioned heating methods and systems like electric heaters and gas fires even with the advent of more efficient systems like Combi boilers. While the initial cost of installing a new central heating system can be scary, if you calculate the long term costs, you’ll realize that a Combi boiler will save you money through improved energy efficiency and reduced energy bills.

Now, the price of new central heating systems (like everything else), varies and also depends on the size of your home and family and how complicated the installation is. When you request for a boiler installation quotation, the cost will include the cost of buying a new boiler ideal for your home, additional pipework needed and labour costs by Gas Safe engineers.

The cost of installing a new central heating system

The number of radiators and bathrooms in your home, coupled with its size, will help in determining the kind of boiler you get – one that will provide you with optimum efficiency and comfort. Generally, there are three boiler types in the industry – these include conventional, system and Combi boilers.

If you want to have a system or conventional boiler installed, you will incur the cost of installing a hot water tank. But since Combi boilers don’t use hot water tanks, they are less expensive. And if you are replacing a system or conventional boiler, you will incur the extra cost of removing the water tank.

Usually, the higher the kW output you need, the more expensive the boiler will be. But even then, we should point out that some brands are more costly than others.

Extra requirements and parts

The boiler is a single element of the central heating system. There are additional elements that are needed to help turn your home into a warm and comfortable space. These extra parts will increase the installation cost. For instance;

  • Buying new radiators if the current ones are old, blocked, faulty and inefficient
  • A power flush may be necessary to get rid of sludge and debris from the current system
  • You may have to install filters to help in increasing the lifespan of the boiler and to help in improving the boiler efficiency
  • The pipework might need to be replaced or rerouted depending on its current condition and if you want to install the boiler in a different position.

These are some examples of extra parts you might need for a complete installation. It is in no way an exhaustive list.


It’s important to ensure that you are working with a Gas Safe registered engineer. This is because only they are allowed to work on gas appliances in the UK. Also, hiring mediocre companies and individuals to help with the installation may work against you since it will void the manufacturer’s warranty. And if anything goes wrong, you’ll have to foot the complete bill.

There’s no doubt that new boiler installation is a huge financial undertaking. But the good news is that the cost will pay for itself over time and second, most boiler installation companies have flexible payment plans you can take advantage of.

5 Ways to Get Your Boiler Ready for Winter

We the Brits take pride in our weather. From time to time, we experience cold days, especially during winter when the temperatures drop to lows. What’s worse is the fact that the low temperatures can last for a couple of days or weeks.

Now, when the temperatures drop below freezing, you want your house to remain warm. This is where your new boiler comes into play. In the guide below, we shall share some tips on how you can ensure your boiler serves you efficiently through the winter season.

5 Tips How To Keep Your Boiler Working Over Winter

Insulate the condensate pipe

Boilers heat houses by circulating hot water through their pipeworks. During winter, the water that helps to keep you warm can turn against you. The water can freeze inside the condensate pipe. This is one of the most leading causes of boiler malfunction during the cold season. Homeowners spend a lot of money getting the problem fixed. Luckily, you can save yourself the inconvenience and hassle by insulating the condensate pipe. This process is best done by a Gas Safe engineer in case alterations are necessary.

Bleed the radiators

Radiators are the heating points of boilers. They spread heat from the water to their immediate environment. They are efficient and heat the room according to the boiler temperature settings. But sometimes air accumulates in the radiator and creates some form of insulation inside against the hot water. When this happens, the bottom is hotter than the top.

As a result of the insulation, the efficiency of the boiler drops and you start spending a lot of money on energy bills. The solution to this problem is bleeding the radiators. Luckily, this process doesn’t require special tools aside from a radiator key that you can buy from your local hardware store.

Check boiler pressure

Another cause of boiler problems during winter is low boiler pressure. This phenomenon is common since the boiler system loses water over time. As such, it’s normal to repressurizing the boiler twice every year. But if you realize you are doing it too often, then the system needs servicing.

Why not also read: Boiler Losing Pressure No Leak

Normal boiler pressure is between 1 and 1.5 bar when the system is off. If the pressure falls below 1 bar, you can re-pressurize it through the filling loops. As you add water to the system, keep an eye on the pressure gauge being sure not to surpass the 1.5 bar threshold.


A boiler service is a sure way of ensuring the boiler is in tip-top shape as you usher in the cold season. The Gas Safe engineer you hire will inspect boiler parts for damage and wear and tear. Any problem detected can be solved before it escalates into a big problem requiring a lot of money to sort out.

Inspect the thermostat

Thermostats help in controlling room temperatures. If a thermostat is faulty, you’ll notice the rooms are either too cold or too hot. Either way, it can be frustrating and uncomfortable. Luckily, a faulty thermostat requires a quick replacement, and you are good to go.


If you follow the above tips and steps, your boiler should be ready for the cold season. But even then, you need to keep an eye out for any anomaly and attend to it ASAP. Also, for any repairs, call our Gas Safe engineers.
