The good news is that many homes keep most of their existing radiators. Older houses were often fitted with radiators larger than they needed, and rooms that have since been insulated may now need less heat. The only way to know is a room-by-room calculation: the heat loss survey works out how much heat each room loses on a cold day and checks whether the radiator already there can deliver it at the chosen flow temperature.
Radiator fitting in Cheshire is scheduled with your heat pump installation so the system is drained only once. Many older houses in Cheshire still have their original single-panel radiators, so the survey checks each one against the room it heats. Extensions and kitchen-diners around Cheshire with large glazed areas get their own radiator calculation.
Who it suits
- Homes switching from a gas, oil or LPG boiler to a heat pump
- Homeowners who want the lowest practical flow temperature for efficiency
- Rooms that already feel slow to heat, such as bay-windowed living rooms
- Rooms with little wall space, where a fan-assisted radiator fits better
Grants and rules for heat pumps in England
Homes in Cheshire 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.
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.
Heat pump radiators prices in Cheshire
The ranges below are typical installed prices for homes in Cheshire, including VAT. A survey sets the exact figure, because two similar-looking houses in Cheshire 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
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.
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.
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.
