Domestic Testimonials


Did the job as requested, good value and friendly. Can't ask for much more.

Graham Pontin, March 2011


They arrived right on time and did an excellent job at a very reasonable cost. I will definitely use their service again and strongly recommend them to anyone needing jobs doing”

Emma Blake, January 2011


I was provided with a timely quote following a visit from Sean to see exactly what was required (unlike another company which felt it unnecessary to visit). The work was then carried out the following week entirely to my satisfaction. A new fuseboard was installed, bonded to the gas and water, and all the sockets and electrical circuits tested. The price was very reasonable and I would definitely use SED Electrical again. I can highly recommend this company.

Sean has a friendly manner, a commitment to a high standard of work and offers excellent value. I would have no hesitation in using his services again. Highly recommended.

S.E.D installed new power lines and multi-media cabling throughout the living room, new dimmers in the bedrooms and new extractors/towel rails in the bathrooms. Considering the amount of work done it was completed on time and within budget. S.E.D were very helpful and more importantly everything worked.
