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.

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 South West, with solar and batteries the fastest-growing part of the book.

  • Founded in 2004 by Chris Williams
  • Run day to day by Dan, third generation in
  • Working across Bristol and the South West
  • Everything to BS 7671, by a DBS-checked crew
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.

  • Legally CW Electrical (Bristol) Ltd, trading as Sunny's
  • The same NICEIC electricians on your roof
  • The same MCS and NICEIC registrations
  • Reviews earned as CW, shared honestly here
The boring bits, translated

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 work to the same standard, because the family name is on the van. No call centres, no franchise badges, no strangers on your roof.

Job card · Solar + battery★★★★★

"Dan was professional throughout and the whole process was very smooth. He organised for scaffolding to go up the week before our install and then he and his dad Chris were on site together for four days. This was followed by a clear handover pack."

"Dan came to do an initial assessment and was able to answer our questions and concerns. He kept us informed regarding starting date. We were clear about the costs from the start. They've done amazing job, very neat and tidy. Dan also helped set up the app so we didn't have to deal with the support ourselves."
