Highlights
“I had snapped a bleed valve off a very expensive towel rail. Deri would not give up until it was fixed. Eventually resulted in the valve being drilled out and a new valve engineered and re-fitted, but otherwise would have cost me over £X to replace. Deri was very professional and knowledgeable and I would have no hesitation in recommending him and using him again. Also had a problem with my underfloor heating. Deri quickly identified the problem, identified online a supplier of the faulty component and returned to fit it.”
“Deri did an absolutely fantastic job. He arrived promptly and completed the job quickly and efficiently. He cleaned up any mess created as he went along to a very high standard. He is a very friendly and knowledgeable tradesman. I would not hesitate in recommending him to others and will be using his services again in the future.”

New Boiler complete central heating system and hot water
Very professional work considerate, clean very tidy. Deri explained the controlling of the thermostat. We were asked our choice of boiler and style of radiators to be fitted. Could not fault any of his work, a gentleman. Would highly recommend Deri without hesitation great job done. HAPPY DAYS
Verified by CheckatradeBoiler replacement, install additional radiator.
Deri replaced my boiler, flushed my central heating system, added a new radiator, installed a new thermostat and fixed my soil stack. I can't find fault with Deri or his workmanship, would recommend and have no hesitation in having him back for any future work.
Verified by CheckatradeNew boiler fitted.
I wanted a new combi-boiler installed in a new location (moved from a bedroom to the kitchen). It was a bit of a tricky job, but I was impressed by the systematic way that Deri approached the job and the clear advice he provided. He kept me informed throughout the process and I am pleased with the finished job, which seems to have been completed to a high standard. Deri seems to have the full range of equipment required and tidied up carefully after the job. He certainly seems to know what he is doing and I felt his quotation was competitive.
Verified by CheckatradeNew bathroom, bath removed and walk-in shower fitted.
Excellent standard of workmanship, wouldn't hesitate to recommend. Very professional.
New boiler
On time, very friendly and polite, and most of all top class workmanship, recommended to my neighbour, and wouldn't hesitate to tell others. First class.

Verified by CheckatradeBathroom refit
Small bathroom removal of bath in favour of walk-in shower new toilet and basin. We wanted new layout to utilise existing plumbing/waste. In the limited space definitely not easy therefore small additional jobs became necessary hence a small increase in the final bill but we were kept informed. We're completely new to the area so had no contacts, phone answered quickly, arranged quote visit kept, work done as booked and we're pleased with the end result.
New boiler and radiators.
Excellent work, considering we are both disabled, system working perfectly.
I had a leak in the heating system and on the boiler down stairs.
Deri was very communicative, everything was explained to me and I knew excatly what I was paying for. He was on time and I will definitely be concatcing him again for future plumbing services.

Approved plumbers on the free WaterSafe register are vetted, qualified to the water regulations and insured. Check they're listed, or find a WaterSafe-approved plumber near you.
Check the WaterSafe registerAgree the call-out fee, the hourly or fixed rate, and whether parts are charged on top, in writing, before an emergency plumber starts. Out-of-hours overcharging and 'while I'm here' add-ons are common complaints.
Be wary of a plumber who, on a first visit, says your whole system or boiler must be replaced. Get a second opinion and an itemised quote (parts and labour separately) before agreeing to major work.
Gas and boiler work is a separate, regulated trade, not general plumbing. Make sure anyone working on a gas appliance is specifically registered to do gas work, and ask to see that registration before they start.
