Detailed reviews
1. Delays and Inaccuracy: The certificates were not issued on time, and when they finally arrived, they contained incorrect details. 2. Unfair Charges: After bringing the errors to your attention, I was asked to pay an additional fee to have the same certificates reissued with the correct information. 3. Industry Standards: I have utilized similar services with other providers in the past, and I have never been charged a "reissue fee" . In my experience with other providers, such corrections are standard and never come with an extra cost. It is clear that this business prioritizes additional
I am so happy with the work done for me by this company. Even though the work I needed done was quite small, the engineer sent was very pleasant, polite and professional. He replaced the batteries in my smoke alarms and replaced the light pendant in one of the bedrooms with ease. He took time to answer questions I had, cleaned up the little mess left while removing the light pendant and checked that everything was in good working order before he left. I think I have found my go to company for dealing with any electrical issues I may have in the future. I am very happy to recommend this company to anyone wanting good service for a reasonable price.
Tony and his team were great again. We have used them over the years and found them to be very polite, efficient and professional. Each time the pricing was transparent. We have no hesitation in recommending THS.
Richard was very professional. He repaired both my vintage lamps to an excellent standard. He’s very knowledgeable and this gave me confidence in his workmanship. I will definitely use THS for any electrical work I may need in the future and I would highly recommend them.
Excellent service. Very impressed with the communication. Quick to get an appointment, the engineer turned up on time, very professional and very respectful of the property. Would definitely use again.

Fantastic service! The electrician did a great job fitting the lamps, professional, efficient, and very tidy. Everything looks perfect, and I’m really happy with the result. Highly recommend!
I called THS Electrical Services to ask if they were free the following day to replace a faulty light switch and replace a broken outside light. Richard Ha asked me to provide a photo of the broken light which I did by email and he responded by return email with a price which I agreed. He arrived at the appointed time and thoughtfully applied plastic shoe covers before coming into the house. He fixed and tested the faulty light switch quickly. Replacing the broken light with the new PIR version I had purchased took a little longer as it was a bright sunny day and mimicking the dark and movement required for the PIR to work was tricky but Richard persevered and got it working to my satisfaction. I was extremely impressed with Richard's clear and prompt communications skills and his professional approach. He even sent a text next morning to check the light was working OK, which it was. I highly recommend this company and Richard in particular.
This is the second time I have used THS for the EICR and resulting remedial work on my rental flat and was again impressed with the professionalism, tidiness and courtesy of Tony and his team. Helpful advice and a high standard of work at a fair price.

came at the time arranged, very clear communication throughout the work. the job was done to a very high standard & everywhere was left clean & tidy. the electrician was friendly & approachable. as I have plenty of updating to do I will certainly be using this company again.
I wasn't sure how the pricing process would work following a request to send photos rather than a site visit to discuss the work. However, that part worked out. and I accepted the quote. When the electricians arrived on the agreed date, Brandon and his team were excellent. Very polite and explained everything well. All clean and tidy and efficient. They are able to adapt to minor changes to the work where things weren't as expected. I will be using them again and very happy to recommend them.

My tenant had no electricity. I called their office in the morning and the electrical fault was diagnosed and fixed before noon. Great service and full explanation of the issue and costs over the phone. I'll be using again - thank you

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.
