How much does a heat pump cost to install in London?

A fully-installed air source heat pump for a typical 3-bed London home usually lands at £4,500–£9,500 after the £7,500 Boiler Upgrade Scheme grant. Pre-grant it's typically £12,000–£17,000. Access and conservation-area siting are the most common London extras.

Are there enough heat pump installers in London?

Do London heat pumps need planning permission?

Most domestic air source heat pumps are permitted development, but London's conservation areas and listed buildings have tighter rules — you may need planning permission and will almost always need building regulations sign-off. Your installer should confirm this before you commit.

Will the £7,500 grant cover a London heat pump?

Yes — the Boiler Upgrade Scheme is a national grant paid through your MCS-certified installer, and it's fully available in London regardless of property value or your income. It takes £7,500 off the installed cost.

Are there tall-building or access fees in London?

Sometimes. Flats, conversions and properties with restricted side access can attract extra lifting/scaffolding or wiring charges that rural installers don't face. Ask for these to be itemised in writing when you compare quotes.
