Before you book: air source heat pump installation in Dinas Powys
Homes around Dinas Powys range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
For older properties in Dinas Powys, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized. Installers working in Dinas Powys plan the order of work so heating and hot water are off for as short a time as practical.
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.
- Houses with reasonable insulation, or a plan to improve it
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
- Homes replacing a gas, oil, LPG or electric heating system
What's included
- Radiator and pipework changes where the design needs them
- Free home survey and room-by-room heat loss calculation
- MCS registration and certificate, plus network operator notification
- Commissioning, handover and a walk-through of the controls
- Boiler Upgrade Scheme application in England and Wales where eligible
Terraced streets in Dinas Powys 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
Homes in Dinas Powys 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.

Designing for Dinas Powys's winters
On the shortest day Dinas Powys gets about 7 hours 50 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

Air source heat pump installation in Dinas Powys: questions
How long does a heat pump survey take in Dinas Powys?
A home survey in Dinas Powys 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 Dinas Powys?
Survey dates depend on how busy installers are in South Glamorgan. We offer the next available dates when you enquire and confirm them in writing.
Can you service a heat pump in Dinas Powys that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Dinas Powys, whoever fitted them. Tell us the make and model when you book.
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.
Do I need new radiators for a heat pump?
Not always; many homes keep most of their radiators and change only a few. Because a heat pump runs at a lower water temperature than a boiler, each radiator gives out less heat, so the survey checks every room against its heat loss. Rooms where the existing radiator falls short get a larger one, with a guide price of £250–£450 each, installed and including VAT.
