Air source heat pump installation in Midhurst: what to expect
The question for a Midhurst 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.
Many homes in Midhurst have a side passage or rear garden with room for an outdoor unit, and the survey checks airflow and distance from neighbouring windows. In Midhurst, cylinder space is planned with you, often in an airing cupboard, utility room or garage.
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
- Homes replacing a gas, oil, LPG or electric heating system
- Owners who want one contract covering design, fitting and paperwork
What's included
- Commissioning, handover and a walk-through of the controls
- Free home survey and room-by-room heat loss calculation
- System design, unit sizing and a written quote
- Radiator and pipework changes where the design needs them
- Boiler Upgrade Scheme application in England and Wales where eligible
For older properties in Midhurst, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized.
Grants and rules for heat pumps in England
Homes in Midhurst 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.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.

Air source heat pump installation in Midhurst: questions
How long does installation take in Midhurst?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Midhurst home states the expected time.
Do you cover Petworth as well as Midhurst?
Yes. We arrange surveys and installation in Petworth, which is about 6 miles east of Midhurst, and across West Sussex.
Do I need new radiators for a heat pump in Midhurst?
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 Midhurst home gives a room-by-room list.
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.
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.
