What makes heat pump prices different in London
London installs sit at the top of the range: labour, parking and access cost more, outdoor unit siting is tighter, and many homes are flats, terraces or in conservation areas where permission and pipework add time.
Installers quoting in London usually cover towns including Croydon, Bromley, Ealing, Enfield and Barnet. If an installer does not routinely work in your postcode area, travel and return-visit costs tend to be built into the price.
The Boiler Upgrade Scheme
Eligible homeowners in London can get up to £7,500 towards an air source heat pump through the Boiler Upgrade Scheme. The grant is claimed by a certified installer rather than by you, so check whether each quote you receive is shown before or after the grant — this is the single most common reason two quotes look thousands of pounds apart. Eligibility depends on the property, the technology and the installer, and we do not assess it for you.
What moves your quote up or down
- Heat loss — a proper room-by-room heat loss calculation determines the unit size. A bigger unit costs more to buy and to run if it is oversized.
- Radiators and pipework — heat pumps run at lower flow temperatures, so some radiators may need to be larger.
- Hot water cylinder — most homes need a new cylinder, and space for it.
- Insulation — loft and cavity work is often recommended first, and changes both the unit size and the running cost.
- Siting the outdoor unit — restricted access, long pipe runs and acoustic requirements all add labour.
