Air source heat pump installation in St Neots: what to expect
The question for a St Neots 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.
Homeowners across Cambridgeshire can arrange a survey in St Neots for a room-by-room design and a written quote before committing to anything. Many homes in St Neots have a side passage or rear garden with room for an outdoor unit, and the survey checks airflow and distance from neighbouring windows.
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 who want one contract covering design, fitting and paperwork
- Houses with reasonable insulation, or a plan to improve it
- Households with room for a hot water cylinder
What's included
- MCS registration and certificate, plus network operator notification
- Commissioning, handover and a walk-through of the controls
- Radiator and pipework changes where the design needs them
- Removal of the old boiler or heaters
- Free home survey and room-by-room heat loss calculation
In St Neots, cylinder space is planned with you, often in an airing cupboard, utility room or garage.
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 St Neots quote.
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.

These are guide prices for Cambridgeshire, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.

Designing for St Neots's winters
St Neots has about 7 hours 42 minutes of daylight at midwinter and 16 hours 47 minutes at midsummer. That swing matters if you pair a heat pump with solar panels: summer generation can cover much of the hot water, winter generation far less.

Air source heat pump installation in St Neots: questions
How soon can you survey a home in St Neots?
Survey dates depend on how busy installers are in Cambridgeshire. We offer the next available dates when you enquire and confirm them in writing.
Do you cover Huntingdon as well as St Neots?
Yes. We arrange surveys and installation in Huntingdon, which is about 9 miles north-east of St Neots, and across Cambridgeshire.
Can you service a heat pump in St Neots that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in St Neots, whoever fitted them. Tell us the make and model when you book.
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.
