Why you can trust us with your heating
Anyone can claim to be good. These are the independent bodies that audit, certify and endorse our work, and what each one actually guarantees you.
MCS Certified Installer
The Microgeneration Certification Scheme is the UK's quality mark for renewable installations, and the legal requirement for claiming the £7,500 Boiler Upgrade Scheme grant. MCS certification means our designs, installations and paperwork are independently audited, and every install is registered with a certificate you'll need for grants, warranties and selling your home.

Heat Geek is the UK's most respected heat pump design and training community, famous for one obsession: designing systems that run at the lowest possible flow temperature for the highest real-world efficiency. Our engineers train to Heat Geek standards, room-by-room heat loss, emitter verification, weather compensation, which is why we survey before we quote, every time.
