What to know about air source heat pump installation in Caldicot
The question for a Caldicot 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.
Installers working in Caldicot plan the order of work so heating and hot water are off for as short a time as practical. Many homes in Caldicot have a side passage or rear garden with room for an outdoor unit, and the survey checks airflow and distance from neighbouring windows.
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.
- Homes replacing a gas, oil, LPG or electric heating system
- Households with room for a hot water cylinder
- Owners who want one contract covering design, fitting and paperwork
What's included
- Free home survey and room-by-room heat loss calculation
- System design, unit sizing and a written quote
- Boiler Upgrade Scheme application in England and Wales where eligible
- Radiator and pipework changes where the design needs them
- Outdoor unit, hot water cylinder and weather compensation controls
In Caldicot, cylinder space is planned with you, often in an airing cupboard, utility room or garage.
Grants and rules for heat pumps in Wales
Homes in Caldicot 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.

Designing for Caldicot's winters
Caldicot sees roughly 7 hours 49 minutes of daylight in late December against 16 hours 39 minutes in June. Milder southern winters suit heat pumps well, though the system is still sized for a cold snap rather than an average day.
How installation works in Caldicot
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Caldicot home, measures every room and checks where the outdoor unit can go.
- You receive a heat loss design and a fixed written quote, with any grant shown where it applies.
- Installers fit the unit, cylinder and any radiator changes, typically over 2–4 days on site.
- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Air source heat pump installation in Caldicot: questions
What size heat pump does a Caldicot 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 Caldicot home.
How long does a heat pump survey take in Caldicot?
A home survey in Caldicot 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.
Do I need new radiators for a heat pump in Caldicot?
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 Caldicot home gives a room-by-room list.
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.
How long does an air source heat pump installation take?
A typical home installation takes 2–4 days on site. It takes longer if several radiators are being replaced, pipework is being upgraded or the cylinder is going in a new location. Your quote sets out the expected programme, including when you will be without heating and hot water. Timings are typical rather than fixed, because older homes sometimes reveal surprises once floorboards are lifted.
