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.
