Great service, came to property to do the quote, easy email correspondence, fair price and itemised quote options. Installation done quickly and efficiently while I was at home and all left neat and clean. Boiler controls etc explained at the end and the engineer John was polite and patient. Thank you.

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.

JustBoilers helped us out during our hour of need on a cold December morning. They were friendly and professional and quickly got on with identifying the issue and then recommending the course of action required to fix it. We have had plumbers try to identify this problem previously but they were unable to diagnose it. I wish we’d just gone straight to JustBoilers and saved a lot of hassle. We will have no hesitation using JustBoilers for all our boiler and heating related issues going forward.

Just Services Group was recommended to me by a friend, and he was right, they are an excellent company to deal with. Paul, who carried out the survey on my boiler, arrived as booked and I had the quote within 10 minutes of him leaving the property. The quote was a very fair price - and the subsequent install (also by Paul) was carried out a week or so later. The job was completed seamlessly, and the old boiler was removed, leaving my place clean and tidy. I was also given a bit of training on the new boiler and Hive system. The team in the office were a delight to deal with, and the after care has been excellent. I would thoroughly recommend this company.
