Air source heat pump installation for Pembroke Dock homes
A heat pump suits most Pembroke Dock homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Many homes in Pembroke Dock have a side passage or rear garden with room for an outdoor unit, and the survey checks airflow and distance from neighbouring windows. In Pembroke Dock, cylinder space is planned with you, often in an airing cupboard, utility room or garage.
We survey your home, design a heat pump system around its real heat loss, and manage the installation from the first visit to the MCS certificate.
- Owners who want one contract covering design, fitting and paperwork
- Houses with reasonable insulation, or a plan to improve it
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
What's included
- System design, unit sizing and a written quote
- Free home survey and room-by-room heat loss calculation
- MCS registration and certificate, plus network operator notification
- Outdoor unit, hot water cylinder and weather compensation controls
- Removal of the old boiler or heaters
Terraced streets in Pembroke Dock often mean a compact unit position at the rear, so siting and sound levels are checked carefully.
Grants and rules for heat pumps in Wales
In Wales 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; £2,500 for air-to-air). The MCS-certified installer named in your quote applies to Ofgem for you, and the grant comes off your Pembroke Dock quote.
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.
Air source heat pump installation prices in Pembroke Dock
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 Pembroke Dock can need quite different radiators and pipework.

Short winter days in Pembroke Dock and what they mean
On the shortest day Pembroke Dock gets about 7 hours 48 minutes of daylight, with the noon sun around 15° up. The heating season runs from autumn into spring, so a heat pump that is sized correctly and set up with weather compensation does most of its work in steady, cool conditions.

Air source heat pump installation 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.
Do you cover Milford Haven as well as Pembroke Dock?
Yes. We arrange surveys and installation in Milford Haven, which is about 4 miles west of Pembroke Dock, and across Dyfed.
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.
Will an air source heat pump be noisy?
Heat pumps are designed to run quietly, but where the unit sits makes a real difference. The survey looks for a position away from bedroom windows and neighbours, with clear airflow, and the installation must pass the MCS noise assessment. The fan is most noticeable on very cold days when the unit works hardest, and a little vapour during the periodic defrost is normal.
What grants can I get for a heat pump?
It depends on where you live. In England and Wales the Boiler Upgrade Scheme gives £7,500 towards an air-to-water heat pump, which the installer claims and deducts from your quote. In Scotland, Home Energy Scotland offers a grant of up to £7,500, with up to £1,500 more for eligible rural and island homes, but you need a written funding offer before work starts. Northern Ireland has no dedicated homeowner heat pump grant at present.
