I have to say hands up the man did a great job on our power flush, our rads where all over place not heating correctly in a 1990s bungalow oil heating, basically burning money before he called. Advised he would let me know the evening if could arrive next morning to me as I was adamant to get it done fast, kept to his word contacted me be here at 9 and kept place clean went though every step with my partner and showed him exactly everything that was done and what came out. Checked in with us few days after to see how was going I can’t fault the man it’s been a treat rooms heat up so much better than before I should have gone it done sooner! If you need it done his your man trust me! 2 kids under 2 you don’t want waste money or heating in this day and age but his very good and reasonable in price. Thanks so much again :-)Posted on Anthony FlemingTrustindex verifies that the original source of the review is Google. My mother is disabled and heating is crucial to her. Joe is always quick to answer the phone and help any time he is needed. We were so happy with the way he looked after my mother we got him in to replace all our rads and fix our heating which has never worked properly. Joe fixed it in a day and at a reasonable price. We are very happy with him and he's great for the chat also. Highly recommended, 10/10 service. Thank you Joe.Posted on sarah-jane HowesTrustindex verifies that the original source of the review is Google. We contacted Joseph after seeing him recommended online, and he was great from the start. We needed a new gas hob fitted and once it was delivered he was here to fit it within 24 hours. He explained everything that they would be doing and even cleaned up after, I was so impressed. The job was done quickly and it looks amazing. Would definitely recommend him to anyone.Posted on Patrick FlynnTrustindex verifies that the original source of the review is Google.

We got joe out to have a look at our plumbing system it was always giving trouble he advised us on what to do to resolve the issues and done a complete overhaul and everything is working perfect there was 5 long days involved doing the work. 1st time in a long time our plumbing system is working properly, would recommend joe for any job 👏Posted on Rebecca TaylorTrustindex verifies that the original source of the review is Google. Joe installed a new oil boiler for us which involved relocating it and removing the old one as well. Joe came out really quickly to assess and quote, explained our options logically and helped us to choose the right boiler to be ready for oil changes in the future. The job was done within a few days, a long days slog but he and his teammate were thorough and left all neat and tidy. Would definitely recommend, thanks Joe!Posted on Patricia AtkinsTrustindex verifies that the original source of the review is Google. Joe is an absolute gentleman and was a pleasure to deal with. I required a boiler to fitted in a very tricky location. Joe's attention to detail was second to none. My house was left in pristine condition.His assistant Dylan was also so helpful and friendly. He came the morning after my call. Outstanding. Thank you so much.Posted on Paul OTrustindex verifies that the original source of the review is Google. Couldn't be happier with the job Joe did. It was a massive job but he was able to upgrade the heating in my really old house and install a new boiler, cylinder, thermostat, radiators and insulated pipes. It's clear he has been doing this forever. He's really professional and competent in his trade, and is down to earth with time for answering questions or offering advice.Posted on Misiu PuchatekTrustindex verifies that the original source of the review is Google.

He recently upgraded our boiler and provided thoughtful recommendations for our entire system. We are extremely pleased with the results.
