Our Story

A family-run electrical firm built on trust, since 2005.

Technical Electrical Solutions was founded by David Nestor in 2005 and has grown into one of the most trusted electrical contractors covering London within the M25 and the whole of Birmingham. Two decades on, we remain proudly family-run — and David personally oversees every single job.

From a full domestic rewire in Camberwell to an annual EICR for a Pimlico apartment block, an EV charger in West London or a full restaurant fit-out for Jamie's Italian — no job is too big or too small. Every engineer is NICEIC registered, DBS checked and works strictly to British Standard BS7671. And we never quote after the work — only before.

Fuse box replacement

Fuse Box & Consumer Unit Replacement

Old wylex fuse box? Rewireable fuses? Tripping every time the kettle goes on? We replace it with a modern 18th-edition consumer unit with RCBO protection on every circuit — properly tested, fully certified, completed in a day.

Same-day or next-day fitting available across both cities. Free quote first, of course.

Full & Partial Electrical Rewires

From a single-circuit kitchen rewire to a whole-house Victorian terrace overhaul, we plan, dust-sheet and protect every property as if it were our own. Minimum disruption, maximum compliance, and a tidy hand-back at the end.

What our clients say about David.

01 / 03
"
Not great at reviews, but David and I crossed paths 7 years ago. He and his team worked on a full rewire of my nursery, and from then on — because of his efficiency and great work ethics — I've always recommended him to associates, friends and family. We're oriental and have many beauty salons and restaurants dotted around London, all of which need to be tested annually. Everyone I've introduced TES to has been very impressed. Here's to another 7 years! An electrician that actually cares.

David has undertaken work for us for years and is the only electrician we use. He explains everything in advance, gets the job done to a good standard and is reasonably priced.
