Air source heat pump installation in Kempston: what to expect
Every property in Kempston 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.
Terraced streets in Kempston often mean a compact unit position at the rear, so siting and sound levels are checked carefully. In Kempston, 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.
- Homes replacing a gas, oil, LPG or electric heating system
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
- Owners who want one contract covering design, fitting and paperwork
What's included
- MCS registration and certificate, plus network operator notification
- Free home survey and room-by-room heat loss calculation
- Boiler Upgrade Scheme application in England and Wales where eligible
- Outdoor unit, hot water cylinder and weather compensation controls
- System design, unit sizing and a written quote
Installers working in Kempston 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 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 Kempston 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.

Short winter days in Kempston and what they mean
On the shortest day Kempston gets about 7 hours 43 minutes of daylight, with the noon sun around 14° up. The heating season runs from autumn into spring, so a heat pump that is sized correctly and set up with weather compensation does most of its work in steady, cool conditions.

Air source heat pump installation in Kempston: questions
Can you service a heat pump in Kempston that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Kempston, whoever fitted them. Tell us the make and model when you book.
How long does installation take in Kempston?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Kempston home states the expected time.
How long does a heat pump survey take in Kempston?
A home survey in Kempston 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.
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.
Will an air source heat pump be noisy?
Heat pumps are designed to run quietly, but where the unit sits makes a real difference. The survey looks for a position away from bedroom windows and neighbours, with clear airflow, and the installation must pass the MCS noise assessment. The fan is most noticeable on very cold days when the unit works hardest, and a little vapour during the periodic defrost is normal.
