Free home survey, no obligation — the Boiler Upgrade Scheme grant claimed for you
For customers referred by Octopus Energy
If you heat with oil or LPG, the Boiler Upgrade Scheme
currently pays £9,000 towards an air source heat pump. We
are MCS certified and Octopus Cosy accredited, so we claim it
for you and take it straight off your quote.
If Octopus introduce you to us, you’re free to choose any installer. There’s no obligation to go ahead with our quote.
Independent companies selected, vetted and monitored by Octopus Energy against safety, quality and customer-service standards. Not Octopus employees
How the partnership works
Swipe to see all three →
01
Two minutes on the form below. The heating fuel
question decides which grant applies to you.
02
We measure your heat loss, size the system and give
you a fixed price with the grant already deducted.
03
Our own engineers, typically over a few days, with aftercare
from the team that fitted it.
Any installation agreement is between you and Heatforce. Octopus Energy isn’t a party to the contract and doesn’t supervise the work on site. Heatforce is an independent company. We are not employed by Octopus, and Octopus does not set our prices
The Octopus Cosy range — 6, 9 and 12 — is designed and built in Britain, and we are accredited by Octopus to design and install it. Which size is right depends on your home’s heat loss, which is what our survey works out. You control it from the Octopus app, and you can pair it with the Cosy Octopus tariff if you want the system to run more of its heating when electricity is cheapest.

Heat output at -5°C outside, 50°C flow
Maximum flow temperature, so existing radiators often stay
Works with existing microbore pipework
Natural refrigerant, quiet operation
Plus up to 12 room sensors (2 included, the rest at extra cost), controlled in the Octopus app
Product warranty on the heat pump
Product figures shown here are published by Octopus Energy for the Cosy 6, the smallest model in the range. Larger homes may need the Cosy 9 or 12 — that’s what our survey works out. Performance in your home depends on your home.
COSY ACCREDITED INSTALLER
The Boiler Upgrade Scheme covers England and Wales. Both rates are claimed through an MCS certified installer, and the installer deducts the grant from your quote rather than you paying it and claiming it back.
