Keston boilers London

Shopping for a boiler is never an easy process, but among the brands, you’re likely to come across in your search is Keston. A well-known brand, they’re one of the best choices if you’re looking for energy efficiency and real power in one affordable package.

Choices Abound

Keston boilers offer you a number of different output options. From 30kW to 55kW, they have what you need. All of their boilers, though, mean you’re buying into the latest energy savings technology. Each one is Energy Saving Trust endorsed, and they have a high SEDBUK rating. Some studies have even found energy efficiency ratings of up to 110% part load with a turndown rate of 5:1. In fact, the entire Keston range has exceeded the energy efficiency criteria of the ETL, so the possibility of taking advantage of financial benefits from various energy savings schemes does exist when you purchase one of these boilers.

They’re ideal in residential applications, particularly larger ones, and they also work well for light commercial settings, depending on the model you decide to purchase.

Peace of Mind

One reason so many people invest in Keston boilers each year is that the newest options come with a five year warranty. Because they’re built to last, Keston boilers almost never mean problems for customers, but the five year warranty can really put your mind at ease.

Every model is British Gas Service listed, which only further proves that these are some of the easiest models on the market to install and use.

Happy Customers

Have a look at our outstanding reviews to see how we treat our customers and their homes.

We had a problem with our boiler and complex heating system that other plumbers refused to touch. Paresh took it on, and fixed it very quickly. The visit was swift and easy, and he was very sensitive to our shielding requirements.
Michael Quicke
Having previously used Rare to do a full system installation, including new heaters, storage tank, new boiler install, bathroom fit & kitchen appliance install and new piping throughout the home, I called upon them again to service our boiler this winter. Pareshs engineers were punctual, they called 15 mins before arriving and methodically explained the work they work going to carry out, serviced the boiler, drained the radiotors and also treated them. They ensured everything was fine and more importantly assured us the system was in perfect order for the winter and made a few adjustments. More importantly then that the engineers completely cleaned up and washed down the working areas leaving our home spotless. Highly recommend this company for all your plumbing needs.

Paresh is unusual for a London tradesman -- he comes when he says he will come, he charges what he says he will charge, and the workmanship is always first class. I cannot recommend him highly enough.
James Robertson
Helped me with underfloor heating issue - I am so lucky to have found them! Great customer service, so knowledgeable - can't recommend them highly enough.

I called Rare on Christmas Day with an urgent boiler problem. The team was very responsive, professional and polite - the issue was fixed quickly and fortunately they saved us from spending Christmas in a cold home with no warm water! Thanks again!
