What to know about air source heat pump installation in Wallingford
Most homes can run on a heat pump if the system is designed properly, and Wallingford is no different. The key is matching the heat pump and radiators to the home's heat loss.
Installers working in Wallingford plan the order of work so heating and hot water are off for as short a time as practical. For older properties in Wallingford, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized.
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
- Houses with reasonable insulation, or a plan to improve it
What's included
- Radiator and pipework changes where the design needs them
- System design, unit sizing and a written quote
- Boiler Upgrade Scheme application in England and Wales where eligible
- Commissioning, handover and a walk-through of the controls
- MCS registration and certificate, plus network operator notification
Many homes in Wallingford 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 England
In England 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), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Wallingford quote.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.

These are guide prices for Oxfordshire, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.

How long is the heating season in Wallingford?
Wallingford 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.

- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Air source heat pump installation in Wallingford: questions
How long does a heat pump survey take in Wallingford?
A home survey in Wallingford 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 Wallingford?
Survey dates depend on how busy installers are in Oxfordshire. We offer the next available dates when you enquire and confirm them in writing.
Do you cover Didcot as well as Wallingford?
Yes. We arrange surveys and installation in Didcot, which is about 5 miles west of Wallingford, and across Oxfordshire.
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.
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.
