Design is what separates a comfortable, economical system from a disappointing one. Heat pumps run most efficiently at low flow temperatures, around 35–50°C, so the survey checks every room's heat loss against the radiator in it and sizes the unit to the whole house rather than to the old boiler's output. Weather compensation controls then adjust the water temperature to the weather outside, so the system runs gently for long periods instead of in short bursts.
Terraced streets in Bedfordshire often mean a compact unit position at the rear, so siting and sound levels are checked carefully. Homeowners across Bedfordshire can arrange a survey in Bedfordshire for a room-by-room design and a written quote before committing to anything. Installers working in Bedfordshire plan the order of work so heating and hot water are off for as short a time as practical.
Who it suits
- Owners who want one contract covering design, fitting and paperwork
- Homes replacing a gas, oil, LPG or electric heating system
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
- Households with room for a hot water cylinder
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 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.

Air source heat pump installation questions
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.
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.
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.
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.
