Boilers & Central Heating Systems Servicing In West London.
Our team of boiler engineers are trained on a wide variate of boiler and heating systems. We recommend having your boiler serviced once a year to keep it working at full efficiency and to lesser the chances of it breaking down when you need it the most. Boiler servicing normally takes only a few hours and the cost is relatively low.

All systems require an external condensing unit, usually installed on the roof, at the rear of the property, or in a side passage. These units must be at least 1 metre away from neighbouring boundaries and fitted according to manufacturer guidelines.
Thanks to modern inverter technology, today’s outdoor units are extremely quiet – far quieter than many people expect and can be discreetly tucked away out of sight.

Really impressed with the air con installation by Ricky and Ethan. The whole experience was excellent from the very start—clear quote, helpful information, and a smooth, professional install on the day. They were friendly, considerate, and did a fantastic job. Highly recommend!


Like a Michelin starred restaurant, Reliant is always reliable and of a very high standard. This time Ethan and Simon meticulously installed a new boiler with great skill and confidence and provided clear instructions on how to operate. No request was too much for them. I wouldn’t dream of using anyone else. Pimlico who?!
