"Ron, James et al were great - full house rewired, were tidy, very fast, and a great price! We were living in the house at the time, they were understanding working around our boxes and mess. Very happy to recommend."

"Ron and Teun were very professional, and the work was completed to a high standard. Very satisfied with the work and service and would highly recommend."

"It has been a pleasure working with Ron and his team. His prices were fair, the service throughout was great and the work was carried out to a high standard. The team also tidied up afterwards. I'd definitely recommend and will be using Ron again."
In Dorking, a lot of commercial issues come from a familiar mix: older buildings in town, busy retail units, and growing business sites that have outgrown their original electrical setup. We help businesses, landlords and facilities teams stay compliant and avoid downtime by fixing problems like:
Aging fluorescent lighting and non-compliant fixtures
Overloaded circuits in offices, workshops, or light industrial units
Emergency lighting failing monthly/annual tests
Poor earthing and bonding (common on EICRs)
Surge protection missing for IT and comms equipment
Thermal hot spots causing energy loss
Outdated switchgear failing compliance checks
We keep your site efficient, safe & audit-ready.
