What to know about heat pump radiator upgrades in Croydon
Homes around Croydon range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
We plan radiator upgrades in Croydon so floorboards are lifted only where pipework genuinely needs changing. Radiator fitting in Croydon 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
- Homes switching from a gas, oil or LPG boiler to a heat pump
What's included
- Making good around brackets and pipe routes, with any decorating agreed in your quote
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- 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
For period homes in Croydon 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 Croydon quote.
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.
What to budget for heat pump radiator upgrades in Croydon
The ranges below are typical installed prices for homes in Greater London, including VAT. A survey sets the exact figure, because two similar-looking houses in Croydon can need quite different radiators and pipework.
| 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 Croydon's winters
On the shortest day Croydon gets about 7 hours 51 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.
The steps for heat pump radiator upgrades in Croydon
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Croydon; 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 Croydon: questions
Can you service a heat pump in Croydon that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Croydon, whoever fitted them. Tell us the make and model when you book.
How long does installation take in Croydon?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Croydon home states the expected time.
How long does a heat pump survey take in Croydon?
A home survey in Croydon usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
Will new radiators be much bigger than my old ones?
Sometimes, but not always. Swapping a single-panel radiator for a double or triple-panel model of the same height and width can raise output substantially, adding only depth from the wall. Where that is not enough, a longer or taller radiator, or a second radiator in the room, may be needed. We agree sizes and positions with you before anything is ordered.
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.
