We specialise in the installation of condensing boilers and renewable energy products from Worcester Bosch.

Gas Boiler Installation

In terms of cost and environmental impact, boilers that are over ten years old waste a lot of valuable energy. In fact, many older boilers waste up to 40% of the fuel they burn instead of converting it to heat.

You should be aware that current building regulations state that any replacement or new gas-fired boiler must be a condensing boiler. Older boilers convert as little as 60% of the fuel they use into heat which will impact your home heating bills, as well as the environment.

We specialise in the installation of renewable energy products and condensing boilers, using the latest technology available. Modern condensing boilers improve efficiency to over 90% which could save you at least 30% per year on your home heating bills. A big saving over the lifetime of your boiler!

Depending on your heating and water demands there are different types of condensing boilers that are available. Please have a look around our site to read more about how we can help.

Boiler Service & Repair

Annual boiler servicing is a wise precaution and we can ensure that your current system is operating to peak performance. We will ensure against Carbon Monoxide leaks and prolong its lifespan. Regular maintenance can also help prevent an unwelcome and expensive system breakdown.

If you have a temperamental heating system, have hot water in the header tank, if it makes noises, have cold radiators or need to continually bleed them then our experts can help you quickly.

You won’t necessarily need a new system, there are many reasons for central heating systems to degrade and we will advise on the best way to get your heating back to its maximum potential as quickly as possible.

Central Heating

Whether you are looking for a brand new installation or want to replace your old heating system, we will provide all the advice, equipment and parts with a warranty of keeping your house warm throughout the year.

Combi boilers that offer the facility of both hot water and heating are in high demand. We work with both private owners and landlords and are able to offer the same level of service across the board.



A power flush is a process that gives your central heating system a thorough clean and can help improve the central heating system’s performance.

Over time some heating systems experience poor circulation resulting in increased noise,  lukewarm radiators, poor hot water and sludge build up. By ‘powerflushing’ your heating system, the sludge and built up residue will be removed via magnetic filtration, making your system work much more efficiently.

Underfloor Heating

Underfloor heating has huge benefits and we, Eco-Gas London, are specialists in providing underfloor heating for the home.

Unlike conventional radiators, which heat the top of the room first, underfloor heating operates at lower temperatures distributing the heat in a uniform, upwards manner to create a warm and cosy environment that prevents cold spots, creates space and adds immediate and significant value to your home.

What Our Customers Think

Highly Recommended!

I just need to recommend John from Eco Gas London who came over to sort out a problem with the loo. Instead of charging us a small fortune for a call out fee, he talked us through how it could be easily rectified and didn’t charge us a penny.

This company is consistently good. Highly recommended!


Eco-Gas were great

Really happy with the work done. We had central heating installed from scratch, in three story Victorian terrace.
John was was extremely professional, approachable and understanding to our unique situation. There was good humour and he was open to answering as many questions-as we had. Communication with John and his team was very good, with job completed in budget. We would definitely recommend them to others and use again.

Excellent job

My elderly Mum moved last year only to find she had no heating and hot water. John came at very short notice on a Saturday evening and did not leave until he had the boiler working. A month or so later John gave us a competitive quote for a new boiler. He talked through our options and explained everything he was going to do.

My Mum is extremely happy with her new boiler and the service that John provided.
