GreenGenUK Ranked in the Top 10 Nationally for Boiler Upgrade Scheme Installs

At GreenGenUK, we’re proud to announce that we have been ranked in the Top 10 installers nationally for the Boiler Upgrade Scheme (BUS). This confirmation came directly from Ofgem, the regulator responsible for overseeing the scheme, following a recent Freedom of Information request.

Even more importantly, our position isn’t just based on vouchers applied for — it reflects vouchers applied and paid out. In other words, these aren’t just promises; they’re real heat pump systems installed and running in homes across the South West.

What is the Boiler Upgrade Scheme?

The Boiler Upgrade Scheme (BUS) is a government initiative designed to encourage homeowners to switch from fossil fuel heating systems, such as oil or gas, to low-carbon alternatives like air source and ground source heat pumps.

Eligible households can receive:

• A £7,500 upfront grant towards the cost of an air source or ground source heat pump installation.
• A £5,000 grant towards a biomass boiler installation in rural properties.

This makes heat pumps more affordable than ever and is helping households across Cornwall, Devon, Somerset, and Dorset reduce their carbon footprint and energy bills.

Competing with the UK’s Biggest Installers

Many of the companies in Ofgem’s Top 10 are large national providers with vast resources and nationwide reach. GreenGenUK’s achievement is different — we’ve earned our place in the Top 10 as a regional installer, delivering projects across Cornwall, Devon, Somerset and Dorset!

Our growth is driven by:

• Local expertise and over 14 years of experience in renewable heating.
• Customer trust, with most of our enquiries coming from referrals and recommendations.
• Hard work from our team, delivering hundreds of installations every year.

This recognition shows that a South West business can stand shoulder-to-shoulder with the largest energy companies in the UK.
