Air source heat pump installation in Caerphilly: what to expect
In Caerphilly, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
In Caerphilly, cylinder space is planned with you, often in an airing cupboard, utility room or garage. Terraced streets in Caerphilly often mean a compact unit position at the rear, so siting and sound levels are checked carefully.
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.
- Households with room for a hot water cylinder
- 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
- MCS registration and certificate, plus network operator notification
- Boiler Upgrade Scheme application in England and Wales where eligible
- Outdoor unit, hot water cylinder and weather compensation controls
- Radiator and pipework changes where the design needs them
Many homes in Caerphilly have a side passage or rear garden with room for an outdoor unit, and the survey checks airflow and distance from neighbouring windows.
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 Caerphilly 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 in Caerphilly: questions
How soon can you survey a home in Caerphilly?
Survey dates depend on how busy installers are in Mid Glamorgan. We offer the next available dates when you enquire and confirm them in writing.
Can you service a heat pump in Caerphilly that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Caerphilly, whoever fitted them. Tell us the make and model when you book.
How long does installation take in Caerphilly?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Caerphilly home states the expected time.
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.
Can I cancel after accepting the quote?
Nothing is ordered until you accept the written quote. Where the contract is agreed away from our premises, for example at your kitchen table, you can cancel within 14 days under the Consumer Contracts Regulations 2013. If you ask us to start sooner and then cancel, you pay only for work done up to that point.
