Air source heat pump installation in Corby: what to expect
Homes around Corby range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
In Corby, cylinder space is planned with you, often in an airing cupboard, utility room or garage. Homeowners across Northamptonshire can arrange a survey in Corby for a room-by-room design and a written quote before committing to anything.
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 and landlords in England and Wales eligible for the Boiler Upgrade Scheme
- Households with room for a hot water cylinder
- Owners who want one contract covering design, fitting and paperwork
What's included
- Commissioning, handover and a walk-through of the controls
- MCS registration and certificate, plus network operator notification
- Radiator and pipework changes where the design needs them
- Free home survey and room-by-room heat loss calculation
- Removal of the old boiler or heaters
Installers working in Corby 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 Corby 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.

Winter daylight and heating in Corby
Corby has about 7 hours 39 minutes of daylight at midwinter and 16 hours 50 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 Corby: questions
Can you service a heat pump in Corby that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Corby, whoever fitted them. Tell us the make and model when you book.
Do you cover Desborough as well as Corby?
Yes. We arrange surveys and installation in Desborough, which is about 7 miles south-west of Corby, and across Northamptonshire.
How long does a heat pump survey take in Corby?
A home survey in Corby 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.
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.
Do I need new radiators for a heat pump?
Not always; many homes keep most of their radiators and change only a few. Because a heat pump runs at a lower water temperature than a boiler, each radiator gives out less heat, so the survey checks every room against its heat loss. Rooms where the existing radiator falls short get a larger one, with a guide price of £250–£450 each, installed and including VAT.
