What to know about replacing an oil or LPG boiler with a heat pump in Daventry
The question for a Daventry 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.
Cottages and farmhouses in and around Daventry often have solid walls, so the survey looks closely at construction and draughts. If your home near Daventry is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries.
Off-gas homes have a lot to plan when switching to a heat pump: the fuel tank, older walls, rural power supplies and higher heat loss.
- Rural and village homes off the mains gas grid
- Detached houses and bungalows with garden space for the unit
- Owners tired of fuel deliveries and tank maintenance
What's included
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Help arranging LPG tank collection with your supplier
- Oil tank draining and removal or making safe, as set out in your quote
- Network operator notification and electrical connection
- MCS certificate and grant application in England and Wales where eligible
Bungalows and detached houses near Daventry running on LPG can move to a heat pump, with the tank collected by the supplier.
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.
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.

Replacing an oil or LPG boiler with a heat pump in Daventry: questions
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.
Where would the outdoor unit go on a Daventry 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 Daventry home.
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.
What happens with a leased LPG tank?
Leased LPG tanks belong to the supplier, so the supplier arranges collection. Check your contract for notice periods and any charges before you fix a date. We time the switchover so you are not left without heating, and once the heat pump is commissioned the supplier can empty and remove the tank. Bottled LPG cylinders are simply returned.
Can a heat pump cope with an exposed rural spot?
Yes. Air source heat pumps are designed to keep working well below freezing, and they periodically defrost, giving off a little vapour, which is normal. In exposed locations the installer chooses a sheltered position where possible, raises the unit to clear snow and let defrost water drain, and sizes the system for the local winter design temperature used in the heat loss calculation.
