The family firm

It runs in the family.

Sunny's is the solar arm of CW Electrical, a Bristol family firm with three generations of electricians behind it. The jacket is new. The hands aren't.

On the tools, as ever
Who you're dealing with

The firm behind the sunshine.

Before the mascot and the marigold there was, and still is, a proper electrical firm. That's the part that matters when there's scaffolding against your house.

CW Electrical, family-run

Chris founded it, Dan runs it day to day, and the standards were handed down before either of them owned a van. Domestic, commercial and industrial electrical work across Bristol and the West Country, with solar and batteries the fastest-growing part of the book.

The famous family album

Sixty years, one trade.

Drag through the decades. Three generations, a lot of vans, and one rule that never changed: do it properly or don't bother.

Ken's era

Dan's granddad Ken was wiring the West Country before decimal money, with a few firms of his own along the way. A reputation for doing it properly, and a son watching from the passenger seat.

So, why "Sunny's"?

Sunny's is how CW Electrical does solar: same people, same standards, considerably more marigold. Your contract, your MCS certificate and your guarantee all sit with the same company that's been answering its phone since 2004. We'd rather tell you that plainly than have you find it out mid-quote.

What the badges actually mean.

Every solar firm waves these logos about. Almost none explain them. Here's what each one does for you, in plain English.

MCS

Your install, certified

The national standard for solar. It registers the system in your name, unlocks export payments, and means the design was done to a published method, not a salesman's mood.

NICEIC

Our wiring, inspected

The electrical contracting assessment body. Our work gets independently checked on a rolling basis, which keeps us sharp and keeps your insurer relaxed.

TrustMark

The firm, vetted

The government-endorsed scheme for work in and around your home. The vetting covers workmanship, trading practices and customer care, and it repeats. You don't get to keep it by accident.

QANW

Your guarantee, insured

Insurance-backed guarantees. If anything ever happened to the firm, your workmanship guarantee would still stand on its own two feet. That is the entire point of it.

The crew

Small on purpose.

A handful of electricians who all answer to the same surname standard. No call centres, no franchise badges, no strangers on your roof.

Three details in, honest numbers back, and the same family standards that have been on the tools since the sixties. If solar doesn't suit your roof, we say so.
