Before you book: heat pump radiator upgrades in Brixton
Every property in Brixton is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
Extensions and kitchen-diners around Brixton with large glazed areas get their own radiator calculation. Radiator fitting in Brixton 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
- Homes switching from a gas, oil or LPG boiler to a heat pump
- Extensions and loft conversions with large areas of glazing
What's included
- Making good around brackets and pipe routes, with any decorating agreed in your quote
- Balancing every radiator so each room heats evenly
- Supply and fitting of new radiators, valves and brackets
- A radiator schedule showing which radiators stay, which change and their outputs
- Room-by-room heat loss figures for every heated room
For period homes in Brixton 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
Homes in Brixton 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.
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.
What to budget for heat pump radiator upgrades in Brixton
Guide prices for Brixton and the rest of Greater London are shown below, installed and inc VAT. We publish ranges rather than a single figure because design details move the price, and the written quote after survey fixes it.
| 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 Brixton's winters
Brixton sees roughly 7 hours 50 minutes of daylight in late December against 16 hours 38 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.
The steps for heat pump radiator upgrades in Brixton
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Brixton; 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 Brixton: questions
How soon can you survey a home in Brixton?
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.
Can you service a heat pump in Brixton that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Brixton, whoever fitted them. Tell us the make and model when you book.
Do you cover Clapham as well as Brixton?
Yes. We arrange surveys and installation in Clapham, which is about a mile west of Brixton, and across Greater London.
Can radiators be changed without draining the whole system?
Radiator changes normally mean draining the heating system, which is why they are usually done as part of the heat pump installation. The system is then refilled, flushed, treated with inhibitor and balanced. Doing the radiators at the same time avoids draining twice and means the new radiators are commissioned with the heat pump.
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.
