Highlights
"Spencer was really quick with communication during the initial quite stage and ran me clearly through all my options and advised me on what was best to do. The team that came, Luke and Luca, were super efficient and tidy and also took the time to work around my children, who were quite excitable! The work carried out was good quality too."
"From the initial contact to the completion of the job I was very relaxed. Spencer arrive as arranged, gave a good quote (even my wife thought it would be more) and the guys who completed where friendly and informative. I would certainly recommend them as their work is accredited and I seemed to be the priority."
"A timely and efficient team of electricians They completed an update of our electrics both outside and inside our property. Great standards of punctuality and professionalism They will stay in my address book"

We’ve used this company twice - they were very professional, approachable and thoughtful, and the work has been completed to a high standard.
Excellent service from Spencer, Andreas and Luke, responsive and professional, very skilled and friendly. Would highly recommend.
We have dealt with SM Electrical Services twice recently, both experiences have been pleasant and professional. All the guys that completed the work have been friendly, thorough and have always been on time. Communication has also been fantastic and we wont hesitate to use them again for future electrical needs! Thank you 🙂
Quality workmanship from SM Electrical Services! Very well organised, prompt, professional and tidy - exactly what you want from an electrician! All work was properly checked and certified to regulatory standards. Highly recommended!
Great experience with this electrician team. The whole process from start to finish was seamless. They were polite, professional, and easy to deal with. They came out to provide a quote and kept me updated throughout, then booked me in without any hassle. The work was completed to a high standard and everything was handled very professionally. I would definitely recommend them to anyone looking for reliable electricians. They will be our go to for any future work we have planned.
Great service - replaced all the lights and an electric radiator. All looks great!
SM responded quickly to the job request for replacement storage heaters. They visited the premises and sent me a video explaining precisely what they would do. The proposal was detailed and looked like good value. They completed the work to a very high standard. I would definitely use them again. Great company.
The trades men arrived on time, they discussed the job, fitted the lamp to the wall where I specified and gave me necessary advice. They remained professional throughout.
Great communication and work done quickly and to a high standard by very professional and polite team.

Really professional service from the beginning. Excellent communication discussing different options and prices, prompt and very professional.
Amazing service! Andreas installed a new plug socket for me quickly and efficiently with no issues whatsoever! Extremely professional and will certainly use them again in the future!
Really happy. Good communication, friendly and reliable. Did the work quickly and tidied up after. Would definitely recommend. Had our extractor fan replaced and it's so much quieter and more efficient. I can't believe I waited so long to get it done.
I recently requested an EV charger installation from SM Electrical Services and they did a fantastic job. The installation was completed very neatly and professionally, with great attention to detail. From the quotation stage through to the site survey, they inspired real confidence and trust, which made my decision to choose them very easy. Highly recommended!
Excellent service from start to finish. Spencer is extremely knowledgeable and organised - which makes discussing/organising the job a breeze. They had good availability and clear pricing. Andreas arrived on time, worked tidily and efficiently to install the fan. 10/10 would recommend.
Really professional and reliable company. Upgraded our circuit board, fitted an extractor fan and completed a number of smaller jobs all in one day.

Smart checks
Before you hire an electrician
In 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.
Look for consistent reviews across several named sources, not one polished profile.
Check any verified credentials, and that the business details independently check out.
