What to know about air source heat pump installation in Stowmarket
The question for a Stowmarket 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 Stowmarket have a side passage or rear garden with room for an outdoor unit, and the survey checks airflow and distance from neighbouring windows. For older properties in Stowmarket, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized.
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
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
- Houses with reasonable insulation, or a plan to improve it
What's included
- Commissioning, handover and a walk-through of the controls
- 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
- Removal of the old boiler or heaters
Terraced streets in Stowmarket often mean a compact unit position at the rear, so siting and sound levels are checked carefully.
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 Stowmarket 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.

Air source heat pump installation in Stowmarket: questions
Can you service a heat pump in Stowmarket that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Stowmarket, whoever fitted them. Tell us the make and model when you book.
Where would the outdoor unit go on a Stowmarket house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Stowmarket home.
How soon can you survey a home in Stowmarket?
Survey dates depend on how busy installers are in Suffolk. We offer the next available dates when you enquire and confirm them in writing.
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.
