Heat pump radiators in Blackheath: what to expect
Homes around Blackheath 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 Blackheath and across Greater London, column radiators can keep the character of a room while giving enough heat at low temperatures. Many older houses in Blackheath 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.
- Extensions and loft conversions with large areas of glazing
- Homeowners who want the lowest practical flow temperature for efficiency
- Rooms with little wall space, where a fan-assisted radiator fits better
What's included
- A radiator schedule showing which radiators stay, which change and their outputs
- Making good around brackets and pipe routes, with any decorating agreed in your quote
- Pipework checks and any agreed pipe upgrades
- Supply and fitting of new radiators, valves and brackets
- Room-by-room heat loss figures for every heated room
In Blackheath, 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
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 Blackheath 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.

Designing for Blackheath's winters
Blackheath 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.

Heat pump radiator upgrades in Blackheath: questions
What size heat pump does a Blackheath 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 Blackheath home.
How soon can you survey a home in Blackheath?
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 long does installation take in Blackheath?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Blackheath home states the expected time.
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 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.
