Heat pump radiators for Finchley homes
In Finchley, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
Radiator fitting in Finchley is scheduled with your heat pump installation so the system is drained only once. We plan radiator upgrades in Finchley so floorboards are lifted only where pipework genuinely needs changing.
We size each radiator to your room-by-room heat loss so a heat pump can heat your home at a low, efficient flow temperature.
- Rooms with little wall space, where a fan-assisted radiator fits better
- Extensions and loft conversions with large areas of glazing
- Homes switching from a gas, oil or LPG boiler to a heat pump
What's included
- Balancing every radiator so each room heats evenly
- Room-by-room heat loss figures for every heated room
- Pipework checks and any agreed pipe upgrades
- A radiator schedule showing which radiators stay, which change and their outputs
- Draining, refilling, cleaning and inhibitor treatment of the heating system
Extensions and kitchen-diners around Finchley with large glazed areas get their own radiator calculation.
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Finchley quote.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.
What to budget for heat pump radiator upgrades in Finchley
These are guide prices for Greater London, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.
| Work | Guide price |
|---|---|
| Replacement radiator, sized for a heat pump (each, fitted) | £280–£500 |
| Upgrade of about 10 radiators | £2,250–£5,600 |
| Pipework upgrade (e.g. microbore to larger bore) | £1,700–£3,900 |
Installed, inc VAT. The survey lists which radiators need changing.
Designing for Finchley's winters
Finchley has about 7 hours 49 minutes of daylight at midwinter and 16 hours 39 minutes at midsummer. That swing matters if you pair a heat pump with solar panels: summer generation can cover much of the hot water, winter generation far less.
The steps for heat pump radiator upgrades in Finchley
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Finchley; the surveyor measures rooms, windows and radiators and looks at cylinder space.
- The design and quote arrive in writing, including radiator changes and the outdoor unit position.
- On installation days the old system is removed and the new one fitted and filled.
- We commission the heat pump, show you the controls and register the installation.
Heat pump radiator upgrades in Finchley: questions
How long does a heat pump survey take in Finchley?
A home survey in Finchley usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
Do you cover Hendon as well as Finchley?
Yes. We arrange surveys and installation in Hendon, which is about 2 miles south-west of Finchley, and across Greater London.
How soon can you survey a home in Finchley?
Survey dates depend on how busy installers are in Greater London. We offer the next available dates when you enquire and confirm them in writing.
How much does a heat pump radiator cost?
A replacement radiator sized for a heat pump has a guide price of £250–£450 each, installed and including VAT. Upgrading about ten radiators in a typical home has a guide price of £2,000–£5,000. The final price is fixed in your written quote after the survey, once the radiator schedule shows exactly which radiators change.
Do I need new radiators for a heat pump?
Not necessarily: many homes keep most of their radiators and replace only a few. The heat loss survey checks each room against its existing radiator at the planned flow temperature. Rooms with large windows, high ceilings or extensions are the usual candidates for an upgrade, while bedrooms often need no change. Your radiator schedule lists every decision.
