Independent Certification

Electrical Testing & Commissioning in London

Independent testing, commissioning and certification for new builds and major refurbishments — including work installed by others. Full documentation, ready for building control sign-off and warranty.

Why it matters

The sign-off that gets a building handed over

Developers and main contractors often need a certified contractor to test, commission and sign off electrical work — sometimes work carried out in stages by different trades. Get it wrong and handover slips, warranties stall, and building control won't pass the job.

We provide that independent verification: methodical testing, proper commissioning, and the complete certification package your inspector and warranty provider expect.

A foot in the door. Many of our larger contracts start with a testing & commissioning brief — it's how new clients see how we work before trusting us with full installations.
