Before you book: air source heat pump installation in Kettering
Every property in Kettering is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
Installers working in Kettering plan the order of work so heating and hot water are off for as short a time as practical. Many homes in Kettering 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.
- Homes replacing a gas, oil, LPG or electric heating system
- Households with room for a hot water cylinder
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
What's included
- Radiator and pipework changes where the design needs them
- Free home survey and room-by-room heat loss calculation
- Commissioning, handover and a walk-through of the controls
- MCS registration and certificate, plus network operator notification
- Outdoor unit, hot water cylinder and weather compensation controls
In Kettering, 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 Kettering 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.

How long is the heating season in Kettering?
On the shortest day Kettering gets about 7 hours 40 minutes of daylight, with the noon sun around 14° up. The heating season runs from autumn into spring, so a heat pump that is sized correctly and set up with weather compensation does most of its work in steady, cool conditions.

Air source heat pump installation in Kettering: questions
How long does installation take in Kettering?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Kettering home states the expected time.
What size heat pump does a Kettering home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Kettering home.
Where would the outdoor unit go on a Kettering 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 Kettering home.
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.
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.
