What to know about air source heat pump installation in Abergavenny
Most homes can run on a heat pump if the system is designed properly, and Abergavenny is no different. The key is matching the heat pump and radiators to the home's heat loss.
Homeowners across Gwent can arrange a survey in Abergavenny for a room-by-room design and a written quote before committing to anything. Many homes in Abergavenny 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.
- Houses with reasonable insulation, or a plan to improve it
- Households with room for a hot water cylinder
- Owners who want one contract covering design, fitting and paperwork
What's included
- Commissioning, handover and a walk-through of the controls
- System design, unit sizing and a written quote
- Removal of the old boiler or heaters
- Free home survey and room-by-room heat loss calculation
- Radiator and pipework changes where the design needs them
Installers working in Abergavenny plan the order of work so heating and hot water are off for as short a time as practical.
Grants and rules for heat pumps in Wales
Homes in Abergavenny 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.

Short winter days in Abergavenny and what they mean

Air source heat pump installation in Abergavenny: questions
Do you cover Crickhowell as well as Abergavenny?
Yes. We arrange surveys and installation in Crickhowell, which is about 6 miles north-west of Abergavenny, and across Gwent.
How soon can you survey a home in Abergavenny?
Survey dates depend on how busy installers are in Gwent. We offer the next available dates when you enquire and confirm them in writing.
What size heat pump does an Abergavenny 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 Abergavenny home.
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.
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.
