Understood us right away, super polite and extremely hardworking. Results are better than we expected on garden lighting and power to small shed.
Absolutely fantastic. No task or problem too big to solve. Tried to get straight onto the manufacturer of my smart meter device to solve the wiring issue. Helped me install my balcony solar! Will be calling again for any plumbing or electrical work!
Dan was great. So professional, friendly and polite. 100% recommend and will definitely use him from now on . Thank you Dan 👏🏾👍🏾
Daniel helped me remove a cabinet and install a new dishwasher in its place! We felt comforted by the fact that he’s both an electrician and a plumber, as we needed to run new electricity under the cabinet. He also helped trim the skirting board to fit around the new dishwasher. His communication, capabilities and professionalism are top notch - would highly recommend.
Exceptional Service from D.E.F Group I wanted to take a moment to express my appreciation for the outstanding service provided by Daniel and D.E.F Group during our recent heating issue. From the moment we contacted them they demonstrated professionalism, efficiency, and trustworthiness. Daniel arrived promptly, even on short notice, and quickly diagnosed the problem with our boiler timer. He offered a more efficient solution that met our needs for heating our care home. Once he installed the new smart thermostat the heating issue was resolved. We are thrilled to have the ability to control our heating both from our phones and via the new thermostat he installed in our hallway. Thank you so much, Daniel, and the entire team at D.E.F Group. We will definitely recommend your services to anyone in need of plumbing, heating and electrical services!!
Dan and Kai were brilliant, not only did they communicate well (clear and regular) with us on the issues, they also highlighted a concerning gas smell which they felt needed fixing asap - and thankfully they did. Wholeheartedly would recommend them to anyone wanting an honest and diligent electrician/heating engineer. Thanks again!
Daniel was so excellent checking gas safety in the house and efficacy of the boiler. A knowledgable, lovely, thorough professional- that was a great experience. He answered all my questions, was efficient without being rushed in his approach.
Daniel was brilliant from start to finish. He fixed my circuit board really quickly and clearly knew exactly what he was doing. Everything was done properly, safely, and professionally, and he took the time to explain what the issue was without making it confusing. He’s genuinely helpful, easy to deal with, and takes pride in his work. You can tell he’s very skilled as both an electrician and plumber. The whole experience was smooth and stress free, which is rare these days. I’d happily recommend him to anyone looking for reliable, high quality work.
Daniel is friendly, professional and conscientious. He came and did a couple of jobs for us: fitted an extractor hood in the kitchen, some communal hall lights and a security light. It needed a new supply which wasn't straight forward but Daniel found a route that caused the least disruption. Great communication throughout and very clear on what he is doing - totally recommended.
Daniel is an exceptional electrician - one the most professional, respectful and diligent I have ever come across. We had an urgent job at our home with a mystery fault causing our fuse box to keep tripping. It put our boiler and oven out of action three days before Xmas. Daniel fitted us in at short notice, came after a long day and was here well into late evening, testing and retesting circuits and sockets throughout the home, until he finally isolated what the causing the RCD to keep tripping and was able to restore us to full power. We loved his determination to solve the problem and his positive, friendly nature throughout. Would recommend without hesitation.
We recently had some plumbing work done at our Church by Daniel, and we were really impressed with his service. He was professional, friendly, and easy to communicate with from start to finish. Daniel came out to us on short notice and was able to get the job done immediately! We also had a really wholesome and genuine conversation while he worked, which made the experience even better. Overall, Dan’s service was excellent, and we would definitely recommend his services.
We used Dan for a lighting job to install a new bathroom light and fix a faulty one in the kitchen. He was great. Professional, fast and kept us informed on what he's doing. Transparent with pricing too with no hidden charges. Would highly recommend.
I am really thankful we contacted Daniel for an Electrical Installation Condition Report and Gas Safety Record for our rental property. I was very anxious when looking for a contractor because we don’t live in London and basically took a leap of faith and hired Daniel based on the positive Google reviews. I am happy to say that Daniel more than lived up to his stellar Google reviews and would definitely hire him again for any electrical and gas related job. I am truly impressed by his responsiveness, high standards and responsibility. He kept us up to date on the work that needed to be done and very quickly followed through and delivered what we had asked for. Most importantly, he gave us peace of mind. Thank you, again!
A True Professional! Daniel just finished rewiring a room for me, and I couldn't be happier with the results. From start to finish, the entire process was seamless. He arrived right on time, which I really appreciated, and was incredibly friendly and professional throughout the job. The quality of his work is outstanding. He clearly takes pride in what he does, and every detail was handled with care. The new wiring is neat, safe, and exactly what I needed. What's more, the price was completely fair for the high-quality work he delivered. It's hard to find such a reliable and skilled tradesperson. I would highly recommend Daniel to anyone needing electrical work and will definitely be calling him for future projects. He's a true professional and a five-star electrician!
I recently hired Daniel for some electrical work, and I couldn’t be more pleased with the results. He was professional, knowledgeable, and efficient from start to finish. Daniel clearly knows his craft—he diagnosed the issue quickly and handled the job with precision and care. What stood out most was his attention to detail and commitment to safety. He took the time to explain what needed to be done and made sure everything was up to standard before wrapping up. The work was done neatly, and he left the space clean and tidy, which I really appreciated. If you're looking for a reliable and skilled electrician, I highly recommend Daniel. Great service and top-notch workmanship!
Daniel was incredibly helpful. I was lucky that he was already working in my area and was able to come and sort out a fuse that had blown. Very knowledgeable and explained everything in a way that I could understand. I would recommend him for anything electric/gas/plumbing you need. Thanks a lot 🙏🏽
Daniel is a great contact to have in your phone. There has been multiple times where we have had sudden emergencies and he has always managed to make time and find a solution. Anything gas related, plumbing, or electrical I'll go straight to Daniel for assistance. Great guy and very trustworthy. Highly recommend.
Daniel was a life saver, initially contacted to help give some TLC to my old heating system, but had a surprise emergency call out which he managed to attend quickly and completed effectively despite the challenges of the job. Very polite, kind and professional. Highly recommended.
Daniel was great and I would highly recommend. He is a great out of the box thinker (there were some unforeseen issues and he found alternative ways to fix it). He stays till he finishes the job and is continually contactable throughout the day and evening. He is dedicated and happy to answer all questions (which I had a lot of!). He is not the cheapest but you really do get what you pay for which is an effective service and a quick turnaround…none of this I am available in 2 weeks time nonsense, but more the next few days I can get it done. I have already recommended him to our neighbour and we will be using his services again.
Daniel was very kind and helpful and absolutely went the extra mile - nothing was too much for him. I couldn't keep my original appointment because I was running late with a hospital appointment but he was very quick to offer to come back later that evening to sort my issue out. He did not want to leave me hanging and I am very grateful to him and would absolutely recommend him.
Daniel performed a thorough electrical installation condition report and provided additional clarification on the issues and potential remedies.
