Before you book: air source heat pump installation in Daventry
Most homes can run on a heat pump if the system is designed properly, and Daventry is no different. The key is matching the heat pump and radiators to the home's heat loss.
Installers working in Daventry plan the order of work so heating and hot water are off for as short a time as practical. Terraced streets in Daventry often mean a compact unit position at the rear, so siting and sound levels are checked carefully.
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.
- Houses with reasonable insulation, or a plan to improve it
- Owners who want one contract covering design, fitting and paperwork
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
What's included
- Boiler Upgrade Scheme application in England and Wales where eligible
- MCS registration and certificate, plus network operator notification
- Radiator and pipework changes where the design needs them
- Commissioning, handover and a walk-through of the controls
- Removal of the old boiler or heaters
Many homes in Daventry 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
Homes in Daventry can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
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 prices in Daventry
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.

Short winter days in Daventry and what they mean
Daventry 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.

- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Air source heat pump installation in Daventry: questions
Do you cover Towcester as well as Daventry?
Yes. We arrange surveys and installation in Towcester, which is about 11 miles south-east of Daventry, and across Northamptonshire.
How long does a heat pump survey take in Daventry?
A home survey in Daventry 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.
Can you service a heat pump in Daventry that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Daventry, whoever fitted them. Tell us the make and model when you book.
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.
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.
