Who we are

For the past 50 years, BTU has been working hard at keeping homes and businesses in Surrey, Hampshire, Berkshire and London warm and cosy with reliable and cost effective central heating.

We have a team of Gas Safe (formerly CORGI) registered engineers on hand to install, repair and maintain systems of all sizes and types.We are a family run business and strive to treat all our customers with fairness and respect, while delivering quality and expertise.

Every day our Engineers are working in homes, schools (every one of them is CRB checked) and business and we have a strong ongoing training attitude so not much can faze our team!

Gas Boilers

If your boiler is over 10 years old, it’s likely your gas bills are higher than they need to be.We only install A-Rated energy efficient boilers (90% efficient) to help reduce your bills.We also look at your heating system as a whole as there may be some parts of your system that no longer comply with Building Regulations and will need to updated at the same time.We also like to make sensible recommendations if there are other parts of your system that are losing you money.


A regular annual service is a vital way of keeping your heat and hot water system working effectively and efficiently.With modern boilers, a lot of manufactures offer extended warranties.However in order for these extended warranties to stand you must be able to prove the boiler has been serviced every 12 months. At BTU our Service Engineers regularly work on Gas and Oil boilers, Warm Air Units, Air Conditioning, and modern Renewable heating systems.


When you lose your heat and/or water at home or work it can seem that your world is coming to an end!At BTU we have a fleet of Repair Engineers on call 24/7 so we can come to your aid straight away. We are well versed on Gas and Oil Boilers, Warm Air Units, Air Conditioning, and modern Renewable heating systems.

When the time finally comes to replace your gas or oil boiler, warm air unit or air conditioning our trusted team of Installation Engineers will quickly and reliably install your new equipment and show you how everything works.

Winter Boiler Servicing

Our experience tells us that the vast number of boiler breakdowns happen in the colder months of the year.This makes sense if you think about it as the boiler is working harder for longer.While our Repair Engineers are on hand should you need them, our Service Engineers can work tirelessly at keeping your boiler well maintained so you should not need to see the Repair Engineer in the first place!
