Plumber

I hired Charlie to replace my unvented cylinder tank. After paying for the job, he left. After checking the system, I noticed that the cylinder thermostat was not working & he or his plumber's mate had damaged both of my utility cupboard doors. I have asked him to fix it several times. It is now 4 weeks since it was originally installed. I said to him, either fix it in the next few days, or I will get someone else to fix it and send him the bill. He came out with threatening & foul language. DO NOT HIRE!

Paid over 8k for new radiators and a boiler. At first, communication was good. But he quickly became extremely unreliable. Often rescheduling or simply not turning up. Now, 5 months later, we still have some major issues (no boiler timer, ongoing water pressure issues, and a flue that's been poorly installed). An independent plumber from Vaillant said this should all be sorted out by the original plumber. BUT he's completely ignored us..!

Charlie quote to repair a leak. Price was too high for me. I either needed other quotes or to lower the price a little. We both agreed to a lower price. Job was to start two days later. That morning, he asked to shift the job to the next day - he was over-worked. The next day he cancelled at the start time - emergency. 3 days later he phoned me at the job start time to increase the price back to the original amount. 1 weeks time wasted, 3 times re-arranged, massive hassle for tenanants and me.

Charlie did more damage to my property than he solved. Had only very hot water coming from shower. He fitted the new part, but left holes in the walls. He attempted to use mosaic tiles to cover shower hole with no water proof membranes. It failed, looked awful & the shower still didnt work (he said it did & it didnt). Used chat gpt to fix the issues myself. This AM we woke up to leak coming from the fittings he put in. Prior to this, he had promised to pay us back 1300 but ghosted us

Our combi boiler was dripping water so we contacted charlie. He showed me exactly what the issue was (a flooded boiler with a very eroded gas pipe). He arrived the next morning and fitted a brand new boiler with no fuss, Charlie is an honest, efficient and friendly chap and I would highly recommend him.

Thank you for your feedback. Due to illness, I had to reschedule the original appointment, which was communicated in advance. When I attended, additional information affected the scope of works, however I confirmed I would honour the originally agreed price. Unfortunately, there was a breakdown in communication regarding the final appointment, for which I apologise. This is not representative of the service I aim to provide, and I appreciate the feedback.

Mr C, CM19

Charlie, agreed a price and was scheduled for Wednesday. He called on the day and rescheduled for Friday, due to feeling unwell. He then called on Thursday and we agreed for him to attend at 1pm. He cam then began renegotiating, which was a surprise as he had all information before arriving. He then agreed to honour agreed price and rescheduled for Tuesday. He never arrived, called or answered my call. I would not recommend Charlie or this company.

Charlie is a genuinely honest and decent person, something that’s sadly rare these days. He did my plumbing work and clearly knows exactly what he is doing. His primary goal is getting the problem properly sorted. He takes the time to explain things clearly, offers fair advice, and does the job right without any pressure or upselling. His integrity really sets him apart from others. Highly recommended

17 January 2025: Charlie of Heatsafe responded immediately to my request, came within 24 hours, and gave a speedy diagnosis of the problem. Although he was unable to effect a repair, he did break the news gently, and gave an acceptable quote for a replacement in the near future. A good man to have on our side,

Very good came out to see if he could fix it but the boiler was beyond repair so we have had a new boiler plus had our system converted into a sealed system he worked hard over 2 days and got it all up and running fantastic company will be using again and boiler is booked on for its first service next year

UPSET, STRESSED AND DISAPPOINTED Had a new boiler in April and a complete sealed system installed, by Charlie and company, cost £6000, paid straight away on completion. Unfortunately, we needed to contact Charlie as our heating didn’t work. Eventually, after many calls and promises. Charlie found the electrics had not been connected properly by his ‘Plumbers’. After many desperate calls and excuses Charlie agreed for us to get it done by an electrician and he would pay, more excuses and still not paid.

Charlie has installed a new boiler today at my property ( replaced the old, broken one), a one day job that was carried efficiently and very skillful. Charlie and his employee has done a great job, professional, tidy and respectful. They also removed the old stuff and also replaced one of my old radiator. I am extremely pleased with the job done, at an affordable price. Charlie is a caring person, very knowledgeable and friendly. Thank you so much Charlie.
