Before you book: heat pump radiator upgrades in Christchurch
The question for a Christchurch home is rarely whether a heat pump can work, but what needs to change to make it work well: radiator sizes, pipework, controls and where the unit goes.
Radiator fitting in Christchurch is scheduled with your heat pump installation so the system is drained only once. For period homes in Christchurch and across Dorset, column radiators can keep the character of a room while giving enough heat at low temperatures.
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.
- Rooms that already feel slow to heat, such as bay-windowed living rooms
- Extensions and loft conversions with large areas of glazing
- Rooms with little wall space, where a fan-assisted radiator fits better
What's included
- 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
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- Room-by-room heat loss figures for every heated room
Extensions and kitchen-diners around Christchurch with large glazed areas get their own radiator calculation.
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 Christchurch 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 Christchurch
Here are typical prices for heat pump radiator upgrades in Dorset, installed and including VAT. Use the guide price tool for a figure based on your home, then a survey confirms it in writing.

How long is the heating season in Christchurch?
Christchurch sees roughly 7 hours 57 minutes of daylight in late December against 16 hours 30 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.
The steps for heat pump radiator upgrades in Christchurch
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Christchurch; 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 Christchurch: questions
Do you cover Bournemouth as well as Christchurch?
Yes. We arrange surveys and installation in Bournemouth, which is about 4 miles west of Christchurch, and across Dorset.
How long does a heat pump survey take in Christchurch?
A home survey in Christchurch 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.
Where would the outdoor unit go on a Christchurch house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Christchurch home.
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.
