A Which? Trusted Trader since 2015

We’ve passed Which?’s assessment and we stick to its code of conduct. It also means you don’t have to take our word for anything: our customers’ reviews sit on Which?’s own site, not ours.

What it means for you

What being a Which? Trusted Trader guarantees you

To join the scheme we passed a thorough assessment, and we agree to a clear code of conduct.

The highest standards of customer care

From your first call to long after the install, you’re dealt with by people who know your job.

Professional conduct, always

Our own engineers, a qualified electrician on every installation, and a home left as we found it.

Fair, open quotations and contracts

A written quotation for the whole job before the surveyor leaves. Nothing hidden, nothing added later.

No hard sell, ever

Take the quote away and think about it. The decision is yours, in your own time.

In our customers’ words

Hear it from the people we’ve worked for

If something isn’t right

An independent route if we can’t put it right

Our business stands or falls by how our customers feel, and we’re only ever a phone call away. If we can’t resolve a complaint through our own complaints policy, the Which? scheme gives you access to the Dispute Resolution Ombudsman.
