Andy
Group Managing Director
Founded Xaver Roofing, launched Xaver Renewables in response to the industry's biggest question: what should a UK roof actually do in 2030?
Meet the team
Engineers, electricians and roofers, under one roof.
Xaver Renewables is a directly employed team of MCS certified installers, chartered engineers and roofing craftspeople. Small enough to know every panel we've fitted, big enough to deliver at commercial scale.
Our mission
Every roof, a power station.
The UK has more than 27 million rooftops. Most of them still do exactly one job, keep the weather out. We think that's a waste. Xaver Renewables exists to change what a roof is for.
Our mission is to design, install and maintain renewable systems that are engineered like the roofs they sit on, watertight, warrantied and worth it over 25 years. Same accountable crew from survey to sign-off. Same standards from our roofing side. New tools for a new decade.
"We didn't get into solar to sell panels. We got into it because the best surface for generating power is one we already know how to build."
— Andy, Group MD
What we stand for
Four values, held on every install.
Future-first
Every roof we touch should generate more than it consumes. That's the standard, not the aspiration.
One integrated team
Roofers, electricians and designers under one roof, literally. No sub-contracted handoffs.
MCS-grade
MCS, NAPIT, RECC, TrustMark, every accreditation the industry demands, and then some.
Numbers, not promises
Modelled yield, real payback, transparent quotes. If the numbers don't work, we say so.
The people
The crew behind every kilowatt.
Directly employed. MCS-certified. On site with you from survey to 25-year monitoring.
