What to know about heat pump radiator upgrades in Cardigan
The question for a Cardigan 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.
For period homes in Cardigan and across Dyfed, column radiators can keep the character of a room while giving enough heat at low temperatures. In Cardigan, bay-windowed front rooms are often the rooms that need a larger radiator when moving to a heat pump.
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.
- Homeowners who want the lowest practical flow temperature for efficiency
- Rooms with little wall space, where a fan-assisted radiator fits better
- Homes switching from a gas, oil or LPG boiler to a heat pump
What's included
- A radiator schedule showing which radiators stay, which change and their outputs
- Making good around brackets and pipe routes, with any decorating agreed in your quote
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- Supply and fitting of new radiators, valves and brackets
- Pipework checks and any agreed pipe upgrades
We plan radiator upgrades in Cardigan so floorboards are lifted only where pipework genuinely needs changing.
Grants and rules for heat pumps in Wales
Homes in Cardigan can use the Boiler Upgrade Scheme, which applies in Wales as well as England: £7,500 towards an air source heat pump, or £9,000 when it replaces oil or LPG heating for installations from 21 July 2026 to 31 March 2027. The MCS-certified installer named in your quote applies and deducts the grant.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Wales has its own permitted development rules for air source heat pumps, so we check what applies to your property, including listed building and conservation-area constraints, at the survey.
Heat pump radiators costs around Cardigan
The ranges below are typical installed prices for homes in Dyfed, including VAT. A survey sets the exact figure, because two similar-looking houses in Cardigan 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.
Winter daylight and heating in Cardigan
Cardigan has about 7 hours 44 minutes of daylight at midwinter and 16 hours 45 minutes at midsummer. That swing matters if you pair a heat pump with solar panels: summer generation can cover much of the hot water, winter generation far less.

Heat pump radiator upgrades in Cardigan: questions
How long does a heat pump survey take in Cardigan?
A home survey in Cardigan 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.
How soon can you survey a home in Cardigan?
Survey dates depend on how busy installers are in Dyfed. We offer the next available dates when you enquire and confirm them in writing.
Do I need new radiators for a heat pump in Cardigan?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Cardigan home gives a room-by-room list.
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.
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.
