Summarised with AI
Darren is responsive and trustworthy. Can be relied on to try the simpler things first and not rip you off with new replacements. He is our go-to person for boiler and plumbing issues. Parking and congestion charge has to be arranged and paid for up front and card payment taken at completion of the job by phone. Invoice and receipt and sometimes videos sent promptly after.
Darren is always responsive, punctual, helpful and clear. He's been servicing our boiler (and occasionally helped with other odd jobs) for several years and I value his reliability and easy manner.
Darren was extremely responsive to my request for a gas boiler service and came out the next day. Would definitely recommend.
Once again Darren came to the rescue--thank you Darren! Let no-one ever say it's hard to find excellent heating and plumbing people in London!
Darren was asked to replace an Horstman controller with a Siemens controller and undertake a basic boiler service. He tried to be helpful at all stages of the process. He did manage to install the Siemens controller. However, it was not done to our standards nor did the installation meet our expectations. In fact, we decided to have it redone. We did not give Darren the opportunity to return and try again. This is in no way a judgement on Darren or his abilities. In our case, his work simply did not meet our standards and expectations. We found Darren at EPG SPECIALISTS LTD on Check-a-trader and Trust-a-trader, where he has mixed reviews.
I am very pleased to recommend Darren for the work he carried out. He was punctual at all times, professional in his approach, and extremely polite and courteous throughout. Darren listened carefully to the client’s instructions and followed them precisely, ensuring that everything was completed exactly as agreed. He kept strictly to the agreed price with no unexpected extras, which was very reassuring. His work was carried out in a clean and tidy manner, and he made sure the area was left neat at the end of each day. Darren also honoured all agreements and timelines, demonstrating reliability and strong attention to detail. Overall, Darren is dependable, professional, punctual, tidy, and easy to deal with. I would not hesitate to recommend him and would happily use his services again.
Incredibly helpful over Easter weekend helping fix a hot-water issue at my home. Great service and even better value. Would highly recommend and use again. Darren is the man!
Always a great and thorough service from Darren. Easy to arrange the annual boiler service and gas safety check at a time that worked for us, and a conscientious and professional job done.
Darren is professional, helpful, knowledgable and solution-orientated. He calmly and swiftly assisted with our boiler troubles, was communicative and patient throughout explaining each step, and persisted when the issues evolved until it was fixed and working. It made a stressful situation much easier to manage. Thank you - would recommend to anyone looking for a brilliant engineer.
Darren attended venue as agreed and carried out work required to a high standard. Efficient and punctual, I will contact him for future work and would recommend him without hesitation.
I asked Darren to come and look at my boiler after another engineer who was doing a service recommended repairs and a replacement of parts. Darren had installed the boiler 12 years earlier and I remembered the excellent service he had given. Turning to him turned out to be a wise move! He responded very promptly, checked the boiler and made quite minor adjustments and reassured me that no major work or new parts were needed. He exudes an air of honesty and reliability, was very professional and charged a very fair price. He also gave good advice for the future. Thoroughly recommended!!
Darren was extremely efficient, easy going and professional. I had a great experience and would use his services again. I’d recommend him to anyone I know.
Fixed leaking boiler. Came over as arranged and sorted it promptly. Friendly and helpful would recommend to anyone!
I called Darren right after Christmas to repair a leak around the tundish of my boiler. He was incredibly efficient, calmed me down over the phone as I was anxious about the dripping and said he would come to fix it, despite it being a holiday, to repair it. He was extremely kind and helpful but because I work late shifts I didn't sleep all night so that when he arrived to do the repair, I think I upset him. I'm really sorry Darren if I did upset you, I just hadn't slept all night. Please accept my apologies if I was rude or short with you, or anything like that. I can tell that you are efficient and brilliant at your job. Forgive me. 🙏🏻
Darren was very professional and communicated throughout the job. He installed two appliances which involved gas and electricity work, and he did both safely. Would highly recommend.
Boiler had ceased working Darren diagnosed fault(fan) sourced parts and completed the repair Was on time polite and neat Good value I would recommend him to anyone!
Darren was fantastic when our boiler suddenly broke down and needed replacing urgently. Throughout the process he was professional, reliable and explained everything clearly. Would highly recommend!
Such great service from Darren. As a landlord with a tenanted flat in Tooting it’s really important to me that my tenant is happy so when the hot water stopped working I had to deal with issue remotely as I live in Yorkshire. Darren was great, I could not have asked for more. I’d totally recommend him. He managed to get to the flat the next day, update me on the problems, recommend solutions, order parts, carry out the work and was professional and courteous with my tenant at all times. Highly recommend!
Darren was great - would totally recommend. Posted on checkatrade for urgent repairs to a gas pipe early one evening. He responded quickly. Asked to have a quick call to see if the work was of interest (given in local area). Talked through it with him and he agreed to come next morning after first job. He arrived next day early and sorted everything out professionally, explained all very clearly, and all was left clean and tidy. Would definitely use Darren again for gas-related work.
Darren fixed the electrical issues regarding the pumps and valves created by the previous guy who couldn't fix them himself! Darren told me what his approach was going to be regarding end to end testing of the circuits and found the problem promptly. Darren also did the GSC and serviced th boiler. Would recommend unreservedly...Good work good communicator.
Darren installed a new gas pipe between the meter and the boiler and he was great from start to finish. I'm a bit anxious paying by the hour for building work but Darren worked really efficiently and completed the job to a high standard. Most importantly, he was really easy to communicate with, arrived when he said he would and charged a fair price. I'll be definitely using him again for future works and have already recommended him to other friends. Thank you for being great!
I support small businesses so never want to leave a bad review. However Darren has caused us so many costly problems, which have had to be rectified by others, that I feel compelled to share. He recently fitted a boiler which the manufactures say does not comply with their installation instructions and they will not cover our 10 yr warranty. Darren denies any problems and was abusive on the phone. We asked him to rectify a WC overflow problem, which ended up flooding the house. There are so many other good plumbers out there, choose someone else and save yourself lots of hassle and abuse.
Recently moved into a house with a complex heating system: underfloor (wet and electric) and gas. Darren was able to come quickly and timely and clearly explained flow of the system, its mechanical components (both necessary and legacy) and the 7 thermostats. A Big Help
Darren came to carry out a gas safety check at our property and did a great job. After we reached out for a quote, Darren came back very quickly and offered helpful availability. When attending to carry out the check, Darren was helpful, friendly and professional and carried out the check thoroughly. Overall, a great experience!
I was thoroughly impressed with the service of EPG from start to finish. Prompt and clear communication, high quality work at a competitive price, excellent customer service and professionalism at all times. EPG are now top of my list to call upon, and I wouldn't hesitate to recommend them to anybody else. Thank you Darren, and EPG, for a truly 5-star service.
