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?!
