What Our Clients Say

Called a few of the big companies, useless! One week to come out and look, then I got cancelled on. Rang these guys and the came out that very same day, and fitted a new boiler really really well 2 days later. Don’t even hesitate. Oh and to top it off was the cheapest of 5 quotes. Now I’m off for a HOT shower.

I rarely post reviews but these guys went beyond the call of duty when they didn’t have to and way out of office hours. Very efficient and very professional. Bravo.

Very professional and tidy job done!John the engineer turned up on time (even early!) and quickly recognised what the problem was, sent me an estimate of the work needed, I accepted and he came back next day and fixed the problem within the estimated time and price, very approachable and much appreciated! Happy customer 👍

Friendly, efficient and affordable service! Richard always arrives on time and takes the time to explain the problem, the possible solutions and makes you feel very comfortable that the problem will be fixed. I've used JustBoilers a few times now and will continue to do so!

I contacted Just Boilers after a routine annual manufacturer's service showed that my boiler was incorrectly - and potentially dangerously - wired to the pressurised cylinder. It had been like that for 8 years but no one had noticed. I was able to get an appointment quickly and Richard not only explained the problem but knew what the solution was. His approach was to look at the whole system which had been tinkered with over time and he gave it a complete overhaul, doing not only the obvious things like fitting thermostatic valves to all of our radiators but he also solved the pressure problem that meant the loft extension has been chilly for the past 30 years. The whole job was done quickly, efficiently, with attention to detail and at a fair price. Highly recommended.

Really fantastic company to deal with and they did a great job replacing our boiler. From getting a quote to communicating to the office staff and getting my boiler fixed the service was fantastic. I felt like they gave the best advice to get us the best deal at the best price in comparison to other companies where I felt as if I was being ripped off. They were extremely professional and put us at ease. They cleaned up after themselves and regularly gave us updates as they installed the boiler. Highly recommended company, would definitely use again (but hopefully don't have to if my boiler behaves!).

Richard Ritson is very experienced and incredibly capable. He managed to diagnose and fix a long standing problem with my central heating system that perplexed another firm (both their plumbing and electrical team). Richard is both a qualified heating engineer and an electrician, which is what you need on site for technical issues. Other firms will often try to charge you for changing parts that might be causing a problem until they fall upon the answer. In contrast, Richard seeks to identify the problem form the outset by drawing on his experience and impressive technical knowledge. Richard is also courteous and fair with his charging - you know where you stand all the way along. I will only use Just Boilers for heating and electrical work from the point forwards.

As a landlord having used ‘insured’ services, this was like a breeze in the park. Next day repair, easy to book, clear communication, worked around my tenant’s availability, arrived on time, kept me informed throughout, took time to explain the problem in layman’s terms, before fixing same day. Courteous to both tenant and I throughout. Highly recommended!

Full boiler service. Engineer was on time, polite and friendly. Really simple electronic paperwork for payment and service. Offered some simple advice on settings to get the most from the boiler and the extended warranty I had with the boiler too. Will use again for next service
