Detailed reviews
Came out to survey property, discussed a range of options and provided a fully costed quote. Kept to quotes price and work carried out over 1 day to a good standard and finish. One minor point - hole made through wall in wrong place was filled but no one told us, which was disappointing given our overall experience

Alex and his team did an excellent job to a very high standard. He was very punctual and left everything clean and tidy. I would highly recommend him and have no hesitation in using them in the future.
I had the Mitsubishi air conditioner 5kw installed today by Alex and his team. Excellent job done by the whole team. Very professional,punctual and tidy. Would definitely recommend and will use them again.
Alex was truly fantastic at quickly sorting the problem. I also asked about ordering a new remote control; he found a great reasonably priced one on Amazon, I'lll get him to service the A/C units next Spring.. Reliable, professional, charged a fair price. He also checked a portable A/C unit which my partner is using in the loft room. Will ask him to return for any electrical jobs in the future. highly recommended!
Great, pleasant, neat and quick work.
First class experience, used a number of times now - highly reccomend.
Alex was punctual, reliable, and thorough throughout the entire process. He took the time to contact the manufacturer directly to identify the correct sensor for our Samsung split aircon unit, ordered the part promptly, and returned as scheduled to complete the repair. Great service from start to finish – very professional and efficient. Will certainly use him again. Reza
Alex from Mill Hill Electrical provided an efficient, high quality & cost effective service & has been a pleasure to deal with. Thanks again Alex Adam
I invited Alex to conduct an EICR check on my property's electrics and found him an absolute pleasure to deal with. He responded very promptly to my initial approach, offered a reasonable quote, and advised he could accommodate the work with just 2-3 days advance notice. He arrived early on the day and was very professional, thoroughly testing my fuse box and sockets and offering lots of useful advice. All in all, I couldn't have asked for a better service. If you are in need of a knowledgeable electrician, who is reliable and trustworthy, I would have no hesitation in recommending him.
My request for an urgent investigation/repair was answered quickly and the electrician was here within 90 minutes! The perosn was polite, took his shoes off at the door, and worked efficiently and cleanly. Very happy with the service and level of communication through out.
Alex had arranged a call out for 16:00 and arrived earlier 15:25 which was great. The issue was identified. Mice had cleanly cut the power cable from the fusebox to the Ring doorbell. Alex replaced existing wire under the stairs with a bigger more isolated cable and routed it such that it was not at ground level so the mice can't get at it. The new wire was then spliced to the existing unbroken wire in the front door hallway area. The doorbell works fine now. The job was done by 15:45. I am happy with the results and the service provided and would recommend Alex and his colleague to others.
Alex kept us fully informed and communicated fully and transparently throughout the process (from system selection (providing multiple options) to organising delivery and installation. During installation (living areas and all bedrooms) his team was completely respectful of our house and minimised the disruption. His team are totally trustworthy and kept us fully informed throughout by talking through the installation and answering the multitude of questions we had. I thoroughly recommend him and his team.
Alex replied to our enquiry very promptly, attended and gave us a competitive quote and booked the job in within a few days. Arrived on time, completed the job efficiently. Alex found a few additional wiring problems that we were unaware of, and without any fuss resolved them. Excellent service and we would not hesitate to recommend and use again.
Mill Hill Electrical UK recently rewired my kitchen's electrical system, and I’m delighted with their work. They offered top-quality consultancy and were highly professional throughout the project. The results were excellent, and I now have a safe, fully functional kitchen. I highly recommend them!
Great team, friendly and polite. They worked with respect for my house, clean and neat job. I had a new air condition system installed, very good for heating, this time of the year. Excellent job! Highly recommended!
Excellent trader, Alex and his team install three air conditioning unit in my house. The work was clean and neat, they protect everything with dust sheet, they wear overshoes covers. I will recommend them to all my relatives.
