MCS certification is the gatekeeper to the Boiler Upgrade Scheme grant. No MCS, no grant. No grant, no customer.
The Boiler Upgrade Scheme grant (£7,500 for air-source heat pumps, rising to £9,000 from July 2026 for oil and LPG-heated homes) is only available through MCS-certified installers. Customers actively filter the official mcscertified.com database for local installers, because no MCS means no grant.
This is why we put MCS in the hero with the grant amount next to it, and link the gov.uk Boiler Upgrade Scheme page directly. Grant-aware homeowners are pre-qualified leads. They've already decided to install. They just need to choose between certified installers. The site that explains the grant clearest wins.
