Deneillson Electrical was employed ot complete all the electrical works to our dining room extension and replace a plastic distribution board with a new metal one. Their knowledge and skill was absolutely out of the top drawer and combined with them actually attending when they said they would attend and complete the tasks they said they would complete was most refreshing. I would certainly use them again if needed and definitely recommend them to anyone else.

Reply from the business
Thank you Lauren. 😊
Del is always on time and his work is always excellent.
Deneillsons Electrical did the electrics for our new kitchen including a new fuse box (the previous one was 30 years old). They discussed what I wanted and made recommendations. They were very professional, and they did a fantastic job that we had them do more work around the house including our bathroom and en-suite. They were punctual, friendly, and always made sure everything was tidy before they left. All the work they did was for us was reasonably priced. I would recommend Deneillsons for any electrical work and I would definitely use them again for any future work.

Found Deneillsons to be very experienced, knowledgeable, thorough and competent - giving me huge confidence in the quality of their work! Would certainly recommend to others.
I had Deneillsons Electrical replace an older type consumer unit (fuse box) with an up to date model with surge protection etc. The work was very professional. Everything was explained to me as it was progressing and no question of mine was too stupid; they did a fantastic job and also left the work area so tidy I'd barely have known they'd been there. The price was very reasonable and I would recommend this company for all your electrical needs. I'll definitely be using them again.
Great service from the team. They were professional, efficient and very knowledgable. Work is very neat and tidy and had no issues. Very punctual and all costs agreed and met in the timeframes as discussed. I certainly would recomend to anyone and will be my first port of call on any electrical work I require going forward.
Great work always.
Excellent work, we are all very impressed. We would definitely recommend this company.
Del did all the electrics for my recently re designed bathroom and also new downlights and extra sockets in a bedroom. Very impressed with the quality of the work and the helpful advice given and would highly recommend him to anyone.
Del and his team had provided great service and good quality electrical work in my parent's house when they were having a new kitchen fitted. We are a returned customer so we know we can trust on him and his team for their work. Del provided a good quote to take care of everything needed in this project and he worked well with JSS installation team. The whole process was seamless. My parents asked for a couple of extra jobs when he was onsite and he provided a new quote promptly so there was no delay in getting everything done on time. He is knowledgeable and provides professional advice. He arrives on time and leaves the place clean and tidy. We are very happy with the work he carried out.
Professional, knowledgeable, and efficient. Found out fault within the hour, and supplied the parts with care taken to avoid damage to decorating. Also, came at short notice.
Was very amenable to do any changes to planned work
Exremely happy with the work carried out in our bathroom and en suite!

Electrical work in homes in England & Wales should be done by a registered competent person who can self-certify it meets the Part P safety rules. Check they're on the official register.
Check the electrical registerIn England and Wales, notifiable electrical work (new circuits, a consumer unit, anything in a bathroom or kitchen) must by law be signed off under Part P of the Building Regulations. Confirm they will handle that.
Prefer an electrician registered with a government-approved competent-person scheme (NICEIC, NAPIT or ELECSA) so they can self-certify the work meets the wiring regulations.
Insist on the Electrical Installation Certificate (or Minor Works Certificate) when the job is done. It is your proof the work is safe and compliant, and you will need it if you ever sell.
