What customers say about Clever Energy Boilers

Brilliant service from all the team. Thanks. Our old boiler died and from a very reasonable quote to fitting a new one within a couple days. Excellent advice and workmanship too

Adrian Charlton, West Yorkshire

My old boiler went kaput, Clever Energy Boilers gave me a great price and fitted my new boiler within 3 days. Very pleased with the work carried out and would not hesitate to recommend to anyone needing a new boiler. A big thank you to both the installation team and the electrical man, both first class.

Mr Herbert, Yorkshire

Did an absolutely amazing job when we needed our boiler replacing. Not only were the cheapest, but also provided a quote within a day, came up with the most practical and best solution, started and completed the job in 2 days precisely as planned, left the place spotless, re-lagged all the pipes neatly, and then removed all the old kit and disposed of it. Really, really impressed, can’t recommend highly enough.

Ms Marie Moor, Driffield, Yorkshire

When we realised our boiler was on its last legs, we got a few quotes to get it replaced. Clever Energy Boilers were not the cheapest but we liked there fact we could pick up the phone and speak to someone, plus they got back to us when we had a query quickly.

Mr Denis Towers, Preston, Lancashire

We were desperate for a whole new boiler and heating system and the prices were terrible then my fella found Clever Energy Boilers so I gave them a ring and booked in for a quote…

Ms Kirsty Higgins, Halifax, Yorkshire

We had previously used Clever Energy Boilers as a family and they had come to us highly recommended. Richard  found a leak as part of tidying up which could have caused significant problems down the line. He found and repaired the problem along with fitting new radiators throughout the property. The job, service and quality was superb. We found them personable but most important all the work which was completed was done to such high quality. It wasn’t an easy job for them but they have further enhanced their reputation with what they carried out. I would therefore have no hesitation in recommending them to other family and friends and we are overall thankful to them for their work.
