Heat pump radiators for Mill Hill homes
Homes around Mill Hill range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
For period homes in Mill Hill and across Greater London, column radiators can keep the character of a room while giving enough heat at low temperatures. Many older houses in Mill Hill still have their original single-panel radiators, so the survey checks each one against the room it heats.
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.
- Homes switching from a gas, oil or LPG boiler to a heat pump
- Rooms that already feel slow to heat, such as bay-windowed living rooms
- Rooms with little wall space, where a fan-assisted radiator fits better
What's included
- Balancing every radiator so each room heats evenly
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- Pipework checks and any agreed pipe upgrades
- Room-by-room heat loss figures for every heated room
- A radiator schedule showing which radiators stay, which change and their outputs
In Mill Hill, bay-windowed front rooms are often the rooms that need a larger radiator when moving to a heat pump.
Grants and rules for heat pumps in England
Homes in Mill Hill can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
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.
Guide prices for heat pump radiator upgrades in Mill Hill
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 Mill Hill's winters
Mill Hill has about 7 hours 48 minutes of daylight at midwinter and 16 hours 40 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 Mill Hill
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Mill Hill; 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 Mill Hill: questions
Where would the outdoor unit go on a Mill Hill house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Mill Hill home.
Do you cover Edgware as well as Mill Hill?
Yes. We arrange surveys and installation in Edgware, which is about 2 miles west of Mill Hill, and across Greater London.
Can you service a heat pump in Mill Hill that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Mill Hill, whoever fitted them. Tell us the make and model when you book.
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.
Can I keep my radiators and just run the heat pump hotter?
You can, but it usually costs more to run. Every extra degree of flow temperature reduces a heat pump's efficiency, so a system designed at 55°C uses noticeably more electricity than one at 45°C for the same heat. A few well-chosen radiator upgrades often let the whole house run cooler, which is the better long-term trade.
