A heat pump radiator upgrade means replacing only the radiators that are too small to heat their room at the lower water temperatures a heat pump runs at. A gas boiler usually sends water to radiators at 60–75°C, while a well-designed heat pump system typically runs at around 35–50°C. Cooler water gives out less heat from the same radiator, so some rooms need more radiator surface to stay comfortable.
Extensions and kitchen-diners around Shropshire with large glazed areas get their own radiator calculation. Many older houses in Shropshire still have their original single-panel radiators, so the survey checks each one against the room it heats. For period homes in Shropshire and across Shropshire, column radiators can keep the character of a room while giving enough heat at low temperatures.
Who it suits
- Homeowners who want the lowest practical flow temperature for efficiency
- Rooms that already feel slow to heat, such as bay-windowed living rooms
- Extensions and loft conversions with large areas of glazing
- Homes switching from a gas, oil or LPG boiler 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 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.
Heat pump radiators prices in Shropshire
The ranges below are typical installed prices for homes in Shropshire, including VAT. A survey sets the exact figure, because two similar-looking houses in Shropshire can need quite different radiators and pipework.
| Work | Guide price |
|---|---|
| Replacement radiator, sized for a heat pump (each, fitted) | £250–£450 |
| Upgrade of about 10 radiators | £2,000–£5,000 |
| Pipework upgrade (e.g. microbore to larger bore) | £1,500–£3,500 |
Installed, inc VAT. The survey lists which radiators need changing.

Heat pump radiator upgrades questions
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.
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.
Are fan-assisted radiators noisy?
Fan-assisted radiators make a low, steady fan sound when running at higher output, and many have quieter settings for bedrooms at night. They are useful where wall space is short, such as a kitchen with few clear walls. They need a small electrical supply, which we plan into the installation if you choose them.
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.
