10 Gas Boiler Installation
Posted 4 days ago
Highly Recommended.
We recently moved to the area and had our old boiler replaced by Reliant Chiswick and the system flushed. We were very pleased and highly impressed with the service from start to finish. John Kearney was very knowledgeable and gave good advice. His quote was the most competitive. Our engineer Alfonso was also very good. He was most helpful and worked steadily, competently and completed the job on time. Alfonso also spotted a wooden frame in the boiler cupboard with one leg standing on a pipe with possible disastrous consequences! We would have no hesitation in recommending Reliant.Verified reviewerJob location: W410 Radiator Installation

Radiator Installation
Reliant replaced all the radiators in my home and did an outstanding job. From start to finish, everything was handled with a high level of professionalism and efficiency. John offered good advice, recommended suitable radiators, and provided a prompt, fair quote. Alfons, the engineer, was a pleasure to have on-site. He completed the work expertly and in a timely fashion, took real care to check that everything was working as it should, tidied up afterwards, and treated my older property with great care and respect. A highly professional service — I would strongly recommend Reliant.Verified reviewerJob location: W1310 Emergency Central Heating Repair

Great service
Very helpful and easy to deal with. Forthcoming about costs and availability. Great service whilst doing the work. Hard to find great tradespeople, but Dennis is certainly one of them. Will be using Reliant for all my servicing and issues going forwards. Thanks again!Verified reviewerJob location: SW1810 Gas Boiler Servicing / Repair

Exactly what we'd hoped for...
Great initial visit to advise on options and plan before the install. Helpful and friendly installation team (Simon and Ethan), who took their time to ensure everything was functioning well and we were given thorough operating instructions. Would recommend.Verified reviewerJob location: SW1810 Plumber
