ENERGY TAILORED FOR YOU
Solar experts who actually listen.
Real people. Real expertise. A 25-year commitment to your home.
“We started GRW Solar because British families deserved better. Better technology. Better service. Better value. Not the hard sell — the right system, designed for your home, installed by people who live in your community.”
THE TEAM
The people behind your energy independence
Not contractors passing through. Your neighbours. People who take pride in every panel, every connection, every system they install.
Karl Wallis: Founder & Director
Solar Design & Strategy
“Every system we design starts with a conversation, not a sales pitch.”
Jamie Smith: Lead Installer
MCS Certified
“I treat every roof like it's my own. Clean lines, secure fixings.”
Izzy Broadbent: Customer Experience
Your First Point of Contact
“When you call GRW, you speak to someone who knows your area and remembers your name.”
OUR APPROACH
No salespeople. No pressure.
We don't send salespeople to your home. Our online tool lets you enter your postcode, select your roof, and get a full MCS-approved solar design with real earnings and savings figures.
Everything you need to make an informed decision — delivered to your door and your inbox. On your terms, in your own time.
YOUR DESIGN
Designed for your roof, not our margin
Every system is MCS-approved and designed for your property using satellite imagery of your actual roof.
Three technology partners. Three package tiers. We recommend the one that fits.
YOUR SUPPORT
Installed in a day. Supported for decades.
Most installations complete in a single day. Our MCS-certified team handles everything.
We support your system for 25 years. Same team. Same number. Always here.

POWERING A CLEANER BRITAIN
More than a company. Part of your community.
We're a real team, not a faceless corporation. When you call us, you speak to the people who designed your system and managed your installation — not a script reader in a call centre.
Every installation brings Britain one step closer to energy independence. Every family we help reduces the country's reliance on imported energy. That matters to us.
