Homeowners across the UK, and right here in Grimsby, are taking advantage of a government incentive that’s transforming how we heat our homes. The Boiler Upgrade Scheme (BUS) offers up to £7,500 towards an air source heat pump installation, and recent figures show the scheme is having a big impact.


According to the Microgeneration Certification Scheme (MCS), applications for the BUS have risen 26% month-on-month in Spring 2024:

  • March 2024: 2,138 applications

  • April 2024: 2,380 applications

  • May 2024: 2,987 applications

That’s nearly 3,000 households in a single month choosing to go greener with heat pumps.


Year-on-Year Growth

Compare those numbers to last year, and the trend is even more striking:

  • May 2024 BUS applications were more than double those in May 2023

  • Applications from January–May 2024 are up 71% year-on-year

This means more people are making the switch, while the full £7,500 grant is still available.


Installations Keep Climbing

It’s not just applications that are increasing. The MCS Data Dashboard reports nearly 5,000 certified heat pump installations in May alone.

That puts 2024 on track to surpass all previous years, with an average of 4,400 installs per month so far—up 26% on the 2023 monthly average.

“Government initiatives such as BUS are a critical part of the drive to make low-carbon heating more accessible and affordable,” said the MCS CEO. “It’s great to see homeowner confidence in home-grown energy is increasing.”

What This Means for Grimsby Households

If you're based in or around Grimsby, the time to act is now. With demand rising, securing your place in the BUS queue ensures:

  • Access to the full £7,500 grant

  • Peace of mind with a certified local installer
