Who We Are - Est. 2014
A UK retrofit team that turns up, gets the standards right, and leaves homes warmer.
We're engineers, surveyors and project managers fitting heat pumps, solar, boilers and insulation across the UK. Every measure is delivered by our own team - never subbed out, never rushed.

Our Mission
Make low-carbon home upgrades feel boringly reliable.
The retrofit industry has a trust problem - vanishing quotes, vague grant promises, sub-par installs. We started GLR to do the opposite: one team, transparent pricing, every measure installed to standard the first time.
"If we wouldn't fit it in our own parents' house, we won't fit it in yours."
What we believe
Four things we won't compromise on.
Standards over shortcuts
MCS, TrustMark, PAS 2030 and Gas Safe - not for the badge, but because the rules exist for a reason.
Householder first
Every job ends with a real person in a warmer home. Survey, install and aftercare are designed around that.
Lower carbon, lower bills
We only fit what we'd put in our own homes. Heat pumps, solar and insulation that actually pay back.
Plain English, always
No "before grant" gymnastics. Real prices, real timelines, real conversations.
