Before you book: heat pump radiator upgrades in Swindon
The question for a Swindon 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.
Many older houses in Swindon still have their original single-panel radiators, so the survey checks each one against the room it heats. We plan radiator upgrades in Swindon so floorboards are lifted only where pipework genuinely needs changing.
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.
- Extensions and loft conversions with large areas of glazing
- Rooms with little wall space, where a fan-assisted radiator fits better
- Rooms that already feel slow to heat, such as bay-windowed living rooms
What's included
- A radiator schedule showing which radiators stay, which change and their outputs
- Pipework checks and any agreed pipe upgrades
- Making good around brackets and pipe routes, with any decorating agreed in your quote
- Balancing every radiator so each room heats evenly
- Supply and fitting of new radiators, valves and brackets
For period homes in Swindon and across Wiltshire, 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 Swindon 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.
Guide prices for heat pump radiator upgrades in Swindon
Here are typical prices for heat pump radiator upgrades in Wiltshire, installed and including VAT. Use the guide price tool for a figure based on your home, then a survey confirms it in writing.

Installed, inc VAT. The survey lists which radiators need changing.
How long is the heating season in Swindon?
Swindon sees roughly 7 hours 49 minutes of daylight in late December against 16 hours 39 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.

- After commissioning you get a handover of the controls and settings, plus the certificates.
Heat pump radiator upgrades in Swindon: questions
Can you service a heat pump in Swindon that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Swindon, whoever fitted them. Tell us the make and model when you book.
Do you cover Marlborough as well as Swindon?
Yes. We arrange surveys and installation in Marlborough, which is about 10 miles south of Swindon, and across Wiltshire.
What size heat pump does a Swindon home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Swindon home.
Can I keep my radiators and just run the heat pump hotter?
You can, but it usually costs more to run. Every extra degree of flow temperature reduces a heat pump's efficiency, so a system designed at 55°C uses noticeably more electricity than one at 45°C for the same heat. A few well-chosen radiator upgrades often let the whole house run cooler, which is the better long-term trade.
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.
