Your contract is with S&K Property Investments and Improvement Ltd, part of the S&K Group, and the installation is carried out by installers we appoint and manage under that contract. Where you are eligible, the MCS-certified installer named in your quote applies for the Boiler Upgrade Scheme grant in England and Wales and deducts it from your price. In Scotland we work alongside your Home Energy Scotland application, and in Northern Ireland we explain what funding, if any, is currently available.
Terraced streets in Surrey often mean a compact unit position at the rear, so siting and sound levels are checked carefully. Homeowners across Surrey can arrange a survey in Surrey for a room-by-room design and a written quote before committing to anything. Many homes in Surrey have a side passage or rear garden with room for an outdoor unit, and the survey checks airflow and distance from neighbouring windows.
Who it suits
- Houses with reasonable insulation, or a plan to improve it
- Owners who want one contract covering design, fitting and paperwork
- Homes replacing a gas, oil, LPG or electric heating system
- 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 prices in Surrey
The ranges below are typical installed prices for homes in Surrey, including VAT. A survey sets the exact figure, because two similar-looking houses in Surrey can need quite different radiators and pipework.

| 1–2 bedroom flat or small terrace | 4–5 kW | £10,150–£13,400 | £2,650–£5,900 |

Air source heat pump installation questions
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.
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.
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.
