Air source heat pump installation for Northampton homes
Most homes can run on a heat pump if the system is designed properly, and Northampton is no different. The key is matching the heat pump and radiators to the home's heat loss.
In Northampton, cylinder space is planned with you, often in an airing cupboard, utility room or garage. Installers working in Northampton plan the order of work so heating and hot water are off for as short a time as practical.
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
- Commissioning, handover and a walk-through of the controls
- Boiler Upgrade Scheme application in England and Wales where eligible
- Free home survey and room-by-room heat loss calculation
- MCS registration and certificate, plus network operator notification
- System design, unit sizing and a written quote
Many homes in Northampton have a side passage or rear garden with room for an outdoor unit, and the survey checks airflow and distance from neighbouring windows.
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 Northampton 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.
What to budget for air source heat pump installation in Northampton
These are guide prices for Northamptonshire, 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.

Winter daylight and heating in Northampton
Northampton 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 Northampton: questions
How long does a heat pump survey take in Northampton?
A home survey in Northampton 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.
What size heat pump does a Northampton 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 Northampton home.
How long does installation take in Northampton?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Northampton home states the expected time.
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.
