What to know about heat pump radiator upgrades in Pembroke Dock
Every property in Pembroke Dock is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
Radiator fitting in Pembroke Dock is scheduled with your heat pump installation so the system is drained only once. In Pembroke Dock, 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.
- Homes switching from a gas, oil or LPG boiler to a heat pump
- Rooms with little wall space, where a fan-assisted radiator fits better
- Homeowners who want the lowest practical flow temperature for efficiency
What's included
- A radiator schedule showing which radiators stay, which change and their outputs
- Room-by-room heat loss figures for every heated room
- 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
Many older houses in Pembroke Dock still have their original single-panel radiators, so the survey checks each one against the room it heats.
Grants and rules for heat pumps in Wales
Homes in Pembroke Dock 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.
There is no VAT on installing a heat pump anywhere in the UK, Wales included, until 31 March 2027. Planning rules for heat pumps in Wales are set by the Welsh Government and differ from England's, so the surveyor checks the unit position against them.
Heat pump radiators costs around Pembroke Dock
These are guide prices for Dyfed, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.
| 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 Pembroke Dock
Pembroke Dock has about 7 hours 48 minutes of daylight at midwinter and 16 hours 40 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 Pembroke Dock: questions
What size heat pump does a Pembroke Dock 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 Pembroke Dock home.
Can you service a heat pump in Pembroke Dock that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Pembroke Dock, whoever fitted them. Tell us the make and model when you book.
How long does a heat pump survey take in Pembroke Dock?
A home survey in Pembroke Dock 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.
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 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.
