Heat pump radiators in Bexley: what to expect
Homes around Bexley range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Many older houses in Bexley still have their original single-panel radiators, so the survey checks each one against the room it heats. Extensions and kitchen-diners around Bexley with large glazed areas get their own radiator calculation.
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
- Rooms with little wall space, where a fan-assisted radiator fits better
What's included
- Room-by-room heat loss figures for every heated room
- Pipework checks and any agreed pipe upgrades
- Supply and fitting of new radiators, valves and brackets
- A radiator schedule showing which radiators stay, which change and their outputs
- Draining, refilling, cleaning and inhibitor treatment of the heating system
In Bexley, 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 Bexley 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.

How long is the heating season in Bexley?
On the shortest day Bexley gets about 7 hours 50 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

Heat pump radiator upgrades in Bexley: questions
How soon can you survey a home in Bexley?
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 Bexley?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Bexley home states the expected time.
Can you service a heat pump in Bexley that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Bexley, whoever fitted them. Tell us the make and model when you book.
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.
