How Do I Choose the Right Boiler UK?

Getting a new boiler is probably one of the most significant purchases you can ever make as a UK homeowner. This is why it is critical to ensure that you pick a reliable and trusted boiler brand that suits your home and of course, your budget.

Replacing your old boiler with a new and more modern unit will help improve the energy efficiency of the central heating system of your home by at least 30% to let you cut back on your heating costs.

Here are some of the key factors you need to consider when shopping for the right boiler before getting a boiler installation:


The natural sludge and debris build-up can have an adverse effect on how efficient your heating system will be. When this happens, the entire system will grind to a halt sooner or later. You can clear your system with a regular powerflush and installing a magnetic filter help prevent the problem from happening in the first place.


Your resources will be significantly drained if your boiler is inefficient. For instance, estimates reveal that a boiler that is already 15 years old might already be wasting as much as 40p of each pound you spend on your hot water and heating bills. This means that efficiency is vital and today’s newest A-rated condensing boilers have a targeted rate of efficiency at 92%.

Environment Impact

Your new boiler can make your home more environment-friendly if you always run your taps as your water heats up. Aside from reducing your usage of water, it also reduces your consumption of energy because a combi boiler will hold the water that it supplies back until this is heated to the desired temperature. Your central heating engineer should know this and keep you informed throughout installation.


You might also want to install a boiler that prevents freezing in the condensate waste pipe during extreme weather conditions to maintain the highest level of performance.


Hygiene is one of the most important considerations that are often taken for granted when it comes to choosing a boiler in the UK. Older gravity-fed systems have open water tanks located in the loft. This means that the water coming from the taps supplied by the tank will not be safe for drinking. This issue can be solved with the use of closed and more hygienic systems.


Limescale is a serious problem for boilers so it is always a wise move to install a scale reducer to slow down its formation. There are now manufacturer warranties that stipulate the installation of a scale-reducing device to maintain the validity of the warranty.


The available space in your home will also likely affect your choice of boiler. Floor-mounted boilers are often installed in utility rooms, kitchen cupboards, or even garages. Wall-mounted boilers, on the other hand, can fit in cupboards, attics, outbuildings, or kitchens.


Finally, your home’s size and the level of hot water and heating requirements in your household also affect the size and type of the boiler you should get. It is a must to heed the advice of a specialist about the best solution depending on your specific requirements.
