Before you book: air source heat pump installation in Henley-on-Thames
Every property in Henley-on-Thames is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
In Henley-on-Thames, cylinder space is planned with you, often in an airing cupboard, utility room or garage. For older properties in Henley-on-Thames, 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.
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme

Grants and rules for heat pumps in England
Homes in Henley-on-Thames can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
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.

Designing for Henley-on-Thames's winters
On the shortest day Henley-on-Thames gets about 7 hours 49 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 Henley-on-Thames: questions
What size heat pump does a Henley-on-Thames 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 Henley-on-Thames home.
Do you cover Marlow as well as Henley-on-Thames?
Yes. We arrange surveys and installation in Marlow, which is about 6 miles north-east of Henley-on-Thames, and across Oxfordshire.
Where would the outdoor unit go on a Henley-on-Thames house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Henley-on-Thames home.
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.
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.
