What to know about heat pump radiator upgrades in Warminster
Most homes can run on a heat pump if the system is designed properly, and Warminster is no different. The key is matching the heat pump and radiators to the home's heat loss.
For period homes in Warminster and across Wiltshire, column radiators can keep the character of a room while giving enough heat at low temperatures. Extensions and kitchen-diners around Warminster 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.
- Rooms with little wall space, where a fan-assisted radiator fits better
- Homeowners who want the lowest practical flow temperature for efficiency
- Homes switching from a gas, oil or LPG boiler to a heat pump
What's included
- Supply and fitting of new radiators, valves and brackets
- Pipework checks and any agreed pipe upgrades
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- Balancing every radiator so each room heats evenly
- Making good around brackets and pipe routes, with any decorating agreed in your quote
We plan radiator upgrades in Warminster so floorboards are lifted only where pipework genuinely needs changing.
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 Warminster 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.
Guide prices for heat pump radiator upgrades in Warminster
The ranges below are typical installed prices for homes in Wiltshire, including VAT. A survey sets the exact figure, because two similar-looking houses in Warminster 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–£5,050 |
| Pipework upgrade (e.g. microbore to larger bore) | £1,500–£3,550 |
Installed, inc VAT. The survey lists which radiators need changing.
Short winter days in Warminster and what they mean
Warminster sees roughly 7 hours 53 minutes of daylight in late December against 16 hours 35 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.

Heat pump radiator upgrades in Warminster: questions
Do you cover Trowbridge as well as Warminster?
Yes. We arrange surveys and installation in Trowbridge, which is about 8 miles north of Warminster, and across Wiltshire.
How long does installation take in Warminster?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Warminster home states the expected time.
How long does a heat pump survey take in Warminster?
A home survey in Warminster 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.
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.
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.
