Why running costs depend on design
Why design decides it
A heat pump sized wrong costs more to run than a boiler. A heat pump designed right costs less. The difference is design.

FAQs
Is the Boiler Upgrade Scheme still available in 2026?
Yes. The UK government’s Boiler Upgrade Scheme currently offers a £7,500 grant toward eligible air source heat pump installations in England and Wales which is rising to £9,000 for homes on oil or LPG. The grant must be applied for through an approved installer and eligibility rules apply. In Scotland the HES Grant can provide even more funding. All details are in the 2026 Heat Pump Guide.
How much does a heat pump installation cost?
Typical systems start from around £4,600 after the BUS grant (replacing gas) or £3,100 (replacing oil/LPG). Enter your postcode above for an exact fixed price.
What does "performance guaranteed" mean?
We guarantee your system's performance in writing, monitor it digitally, and fix it free if it underperforms.
Do you handle the BUS grant?
Yes. We apply on your behalf. The grant is subtracted from your price before you pay, so there's no paperwork for you.
Do I qualify for £9,000 or £7,500?
It depends on what you’re heating with now. Enter your postcode and we’ll tell you which rate applies to your home.
