Heat pump radiators in Mitcham: what to expect
In Mitcham, 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.
Many older houses in Mitcham still have their original single-panel radiators, so the survey checks each one against the room it heats. Radiator fitting in Mitcham is scheduled with your heat pump installation so the system is drained only once.
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.
- Homeowners who want the lowest practical flow temperature for efficiency
- Rooms with little wall space, where a fan-assisted radiator fits better
- Rooms that already feel slow to heat, such as bay-windowed living rooms
What's included
- Making good around brackets and pipe routes, with any decorating agreed in your quote
- Pipework checks and any agreed pipe upgrades
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- Balancing every radiator so each room heats evenly
- A radiator schedule showing which radiators stay, which change and their outputs
For period homes in Mitcham and across Greater London, column radiators can keep the character of a room while giving enough heat at low temperatures.
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 Mitcham quote.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.
Guide prices for heat pump radiator upgrades in Mitcham
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.

|---|---|
| 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.
Short winter days in Mitcham and what they mean
Mitcham sees roughly 7 hours 51 minutes of daylight in late December against 16 hours 37 minutes in June. Milder southern winters suit heat pumps well, though the system is still sized for a cold snap rather than an average day.

Heat pump radiator upgrades in Mitcham: questions
How long does installation take in Mitcham?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Mitcham home states the expected time.
Can you service a heat pump in Mitcham that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Mitcham, whoever fitted them. Tell us the make and model when you book.
What size heat pump does a Mitcham home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Mitcham home.
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.
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.
