About DT Electrical Contractors

Founded in Penzance. Built on doing things properly

NICEIC Registered | Fully Insured | Isles of Scilly Approved

Cornwall's Electrician. Done Properly.

As an electrical contractor Cornwall residents and businesses have trusted since 2005, DT Electrical Contractors was founded by Daniel Thompson in Penzance and has grown into one of the county's most reliable electrical teams.

Dan started his career as an apprentice electrician in 1998, completing his apprenticeship in 2001. Four years later he went out on his own, building a reputation across West Cornwall for quality, reliability and doing things right first time. By 2007 the demand for DT Electrical's services had grown enough to expand the team, and the business has been growing ever since.

Today DT Electrical covers the whole of Cornwall and the Isles of Scilly. The team handles everything from domestic rewires and consumer unit replacements to commercial installations, EV chargers, solar panels and emergency callouts. As an NICEIC registered electrical contractor, every job is certified to the highest industry standard and fully documented on completion.

What sets DT Electrical apart from other electrical contractors in Cornwall is the personal service. When you call, you speak to Hannah or Dan directly. There are no call centres, no engineers dispatched from Bristol, no impersonal ticketing systems. Just a local Cornish team that knows the properties, understands the community and turns up when they say they will.

DT Electrical is also proud to be one of the few electrical contractors regularly serving the Isles of Scilly. The team frequently travels to the islands to provide electrical services to residents and businesses in one of the most remote locations in the UK - a commitment that reflects the company's dedication to covering Cornwall properly, from Land's End to the Scilly Isles.
