Change of fuse-board
Customer Service
My old fuse board was changed for a new fuse-board and a new cable was run to my summer house for garden lighting. Richard and Tom explained the job clearly, were obviously very experienced and the work was done cleanly in the planned time. Really can’t fault this company. They have been operating for 20 years and it shows. I would highly recommend them.

Installation of patio lights; kitchen fan repair
Customer Service
Thornton Electrical promptly ascertained our requirements and sent us an estimate. On the agreed day, they arrived punctually. The work was carefully planned, taking into account any requests we made, and was carried out neatly and efficiently. The electrician was at all times polite and considerate. We were delighted with the results. The area was left clean and tidy. We shall certainly employ Thornton Electrical when we need any further work to be done.

Electrical Work at Home
Customer Service
An excellent service was afforded by Thornton Electrical. during work carried out in autumn 2014 and Spring 2015. My whole kitchen and bedroom was re-wired when it was renovated, an up to date circuit board was installed and an extractor fan in the bathroom. The whole of the house for checked while the work was being carried. The service was efficient and carefully undertaken to the best standard I could have ever asked for. During the kitchen refit the electricians fitted in very well with the kitchen fitter and he himself was most complimentary and impressed about the knowledge and service of the electricians. The service was always prompt, courteous and very reliable. Helpful and useful advice was given about electrical equipment and types of fittings which could be used. We are more than happy with the work carried out and would have no hesitation in recommending Thornton Electrical to you.
Excellent, prompt and professional.

Excellent service
Customer Service
We have used this company several times now but most recently for a larger job. They are efficient, cost effective, professional and a pleasure to have in your home. A special thank you to 'Jamie', one of the electricians who came to our home on several occasions, he is polite, cheerful and has a lot of patience. In addition nothing was too much trouble for Steve and his workers. We would definitely recommend this company and certainly use them again.

New electrics and heating system in a church
Customer Service
Thornton Electrical provided a very professional service. They assessed what needed to be done regarding modernising the electrics in our church to conform to the latest legal safety requirements and suggested alternatives to improve our heating system. They were always punctual, gave clear advice stating the options and benefits, worked unsupervised and cleaned up after the job all in a friendly, helpful way. The work was completed on time with no money paid until I was completely satisfied with what they had done. I cannot praise them highly enough and have no hesitation in recommending them.
