What Our Clients Say
Fantastic company to work with (and I have done so on a number of occasions for different issues over the past 6 years). Great communicators - they are very responsive and very clear about the scope, the pricing and the expectations. Fantastic team, very professional and very reliable, always arrive with a smile and a friendly attitude and always see things through to successful resolution. And the prices are very reasonable. Colville is not only my favourite plumber, but also all of my neighbours' favourite plumber. He is absolutely fantastic.

Service was fantastic. The main desk were very helpful and efficient, Colville was exceptional. Visited the property very quickly, provided advice and even checked in on Sat to top up the boiler as a gesture. Then completed the job before throwing in some boiler efficiency advice as we head into winter. Thoroughly recommend. Decent value too.

Full boiler and thermostat installation. Extremely professional, reliable and good pricing. We got multiple quotes including bigger companies such as British Gas and their service was flawless from start to finish. Gordon, our heating engineer was excellent. No faults, would definitely use again. Thank you

Excellent customer service following my initial telephone call and understanding of the problem with my boiler. Courteous and clear with regard to price of attendance and supply of parts etc.. Engineer notified when on the way and arrived on time. Highly knowledgeable to resolve the immediate issue and gave good advice as to the next stages of the longer term repair. Faultless from state to finish. Very happy.

My ceiling got flooded during the heavy downpours back in May, this was due to poor maintenance of the building façade and blocked gutters, but the freeholder refused to handle it and blamed it on the boiler company even though it wasn't their responsibility! They were very patient through the whole process, provided all the evidence, liaising with everyone. Considering the stubbornness of the freeholder in his refusal to cover the costs of the repairs, JustBoilers ended up fixing my ceiling for free! I am very pleased with the work they did, their contractor was friendly and on time, so were the engineers I met for the various inspections. I highly recommend JustBoilers for their professionalism and flexibility. They had no obligation to take care of this and I really appreciate the gesture.

JustBoilers - the clue is in the name, and confirmed by their website. I entered my number and was called back within twenty seconds. My old boiler had stopped working and would have to be replaced. After an initial assessment the engineer returned two days later and I now have a Glow worm Betacom4 24kw. It's quiet, efficient and reliable. A big improvement on the old boiler and much more economical. Very efficient service.

I don’t often review but making an effort for that company because of how good they were to me.My combi boiler was suffering from an intermittent fault which caused it to regularly break down. Hundreds of pounds spent on new parts and 4 separate engineer visits from 3 different companies had failed to solve the issue ans I was finally resigning myself to getting a new boiler installed.The Just Boilers engineer initially came in to quote on a new boiler install but, upon taking a closer look, told me that he didn’t think that a new boiler was warranted and that he could fix my current one instead - before promptly proceeding to pulling this off!I seriously still can’t decide whether I was more impressed by the honesty or the technical skills...In any case, I really can’t recommend them highly-enough...

Almost went for British Gas, so glad I didn’t. Not only did I save over £1000 but a better boiler was fitted on the date requested. The installer, Aaron, was very professional and efficient; providing excellent guidance on the best boiler for my requirements. Cannot recommend this company enough.

Amazing service provided by a very professional company. From the moment go this was organisation well above the shoulders of many others we had contacted. From the quote , to quickly arranged visit and the service itself. Many things really stand out but what really impressed us was no nonsense taking engineer called Darren who assessed the issue very quickly and simply provided us with a quote of what we really needed rather then sell extra things which quite frankly many other companies did try. Five stars for listening , really it’s hard nowadays to get someone to listen . Mostly people just hear so this was quite refreshing. The service on the day also provided by Darren was just hustle free and non intrusive in any way. I actually managed to do more work whilst having my boiler replaced then I would normally do in my office. Darren proved to be very skilled, amazingly professional , super friendly , quietly efficient and very very clean. I only wish all home works were so easy . Time to expand guys. Totally impressed.

A fantastic company. John the engineer arrived on time and was so helpful and thorough. He fixed the boiler which hadn't been working properly for years. I was given clear quotes re pricing and the whole job was run very efficiently. I can't recommend them highly enough.
Kate Clevely
15:18 09 May 19
Prompt, Fast and Honest. Really helpful friendly customer service. Was assuming it was all going to be a nightmare organising everything, but these guys were great. John the installer was excellent and made me feel very confident in his abilities. He explained everything really well and showed me where the problems were in my ancient boiler. Decided to go for a new one and was surprised at the competitive price and advice. Turned up the following day on time and sent me a reassuring text on his ETA.Would definitely recommend these guys to anyone who needs a boiler serviced or installed. Two thumbs Up.

Hailey was very polite and trying to get the best times for me over the phone. There were no hidden charges, John Millen was very efficient, there was a leak in my boiler that was fixed within an hour and he even helped dry the water that was all over the kitchen floor. Very happy with this company, thank you.

In a world where every plumbing company seems to be all about ripping customers off with high fees or untrustworthy workers it’s so refreshing to have found justBoilers. The staff are all so professional and helpful and their pricing/after care service are both fair and sensible. Recommended!

I've used Just Boilers a few times now and I rate them really highly and have already recommended them to friends and family. When you know nothing about boilers it can be scary to get an engineer in as you are at their mercy in terms of being told what the issue is and how much it will cost but my experience with Just Boilers have proved to me that they are an honest and straightforward company to deal with so that's why have no qualms about recommending them.Their call handlers and customer service people are excellent and if you have further queries they are able to explain it in layman terms.

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 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
