Thomsett Electrical works with businesses across Stevenage and the SG1 and SG2 postcodes. We take on commercial installations, fit outs, lighting schemes and planned maintenance and we do the disruptive parts out of hours so your business keeps trading. Stevenage is around half an hour north of us on the A602 and A1(M).
The commercial premises we cover in the town include the Gunnels Wood Road corridor, which is one of the biggest industrial and technology estates in Hertfordshire, plus the Pin Green and Wedgwood Way units.
Gunnels Wood covers a huge range of premises, from small trade units to large manufacturing sites and three phase work is a big part of what we do there.
Shutting a business down to do electrical work is expensive, so we plan around it. On testing and lighting jobs we work zone by zone. On bigger installations we phase the work and do the noisy or disruptive parts early, late or at weekends.
You get one point of contact, a written quote before we start and full certification when we finish.
