Octopus typically quotes around £4,460 for a heat pump installation after applying the £7,500 Boiler Upgrade Scheme (BUS) grant. While adverts once claimed prices “from £500,” this figure applies to a small number of cases and is widely considered misleading. Overall, Octopus remains competitive when full-service convenience is valued, especially for customers seeking smart, integrated heating solutions. Here’s our full Octopus Energy heat pumps pricing review.

What’s included in Octopus’s quoted price?
As of 2025, Octopus estimates a heat pump installation costs around £4,460, post-grant. This covers everything needed for a complete, MCS-compliant install:
- The air-source heat pump unit (Octopus Cosy or Daikin)
- Hot water cylinder, radiators (if needed), piping, plumbing, electrical work, and installation labour
- Asbestos testing and EPC application (if required)
- A product warranty: 8 years for a Cosy heat pump, or 5 years for other brands
- 2-year warranty on other parts and 5-year workmanship warranty
- Full aftercare and support from Octopus’s dedicated team
What about the “£500 install” claim?
Octopus’s advertising of heat pumps “from £500” has been ruled misleading by the Advertising Standards Authority (ASA). The ASA found that fewer than 6% of customers paid that amount, well below the 10% threshold required for such claims. Octopus disputes the ruling and cites that 13.9% of installations actually met the £500 threshold during the campaign—but transparency remained a concern.
Is the pricing competitive?
Yes. Octopus is among the UK’s leading heat pump installers, offering their own Octopus Cosy 6 and 9 models. The Cosy 6, in particular, stands out for its affordability and compact design. Costs typically start from £4,300, inclusive of standard labour and components.
What customers say – reviews
- On Reddit, some early adopters reported extremely low installs—e.g., £400 or even £500, but these are not the norm. Others received quotes of £14,000–£15,000 for flats or complex jobs, implying significant variability.
- A YouTube user shared a quote of £6,290.99 after grant for an installation that included radiator replacements, illustrating that additional works can push prices beyond the headline figure.
