If a technology is not right for your property, we will say so rather than sell it to you.
Brought to you by The Green Co-op and partners.
Quality home energy,
made affordable.
Grenie connects households across the UK with selected installation partners and quality renewable technology — heat pumps, solar, battery storage and EV charging — with straightforward support from first question to switch-on.
No obligation, no guaranteed-savings promises, and an honest answer if your property is not ready yet.

A quality heat pump installation with £0 customer contribution
For qualifying homes, Grenie's selected package can be fully covered by the Boiler Upgrade Scheme grant—meaning no customer contribution for the standard installation included in the offer.
Subject to Boiler Upgrade Scheme eligibility, property suitability, survey, heat-loss calculation, technical design and approval by the appointed MCS-certified installer. The £0 contribution applies only where the agreed standard package and installation are fully covered by the available grant. Additional works, system upgrades or non-standard requirements may cost extra. Eligibility and a no-cost installation are not guaranteed.
