Oil and LPG boiler replacement means swapping a boiler that burns delivered fuel for an air-to-water heat pump running on electricity, then decommissioning the fuel tank. Homes off the gas grid are often rural, detached or older, so they tend to lose more heat than a typical suburban house. That makes careful heat loss design especially important, but it also means there is usually space outside for the unit.
Bungalows and detached houses near Norfolk running on LPG can move to a heat pump, with the tank collected by the supplier. Rural properties near Norfolk usually have garden space for the outdoor unit, sited away from windows and sheltered where possible. Cottages and farmhouses in and around Norfolk often have solid walls, so the survey looks closely at construction and draughts.
Who it suits
- Older oil boilers nearing the end of their life
- Owners tired of fuel deliveries and tank maintenance
- Detached houses and bungalows with garden space for the unit
- Eligible homes in England and Wales within the higher grant window
Grants and rules for heat pumps in England
Homes in Norfolk 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.
Oil and LPG boiler replacement prices in Norfolk
These are guide prices for Norfolk, 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.
| Home | Typical size | Installed guide price | After £9,000 grant |
|---|---|---|---|
| 1–2 bedroom flat or small terrace | 4–5 kW | £9,500–£12,500 | £500–£3,500 |
| 2–3 bedroom terrace or semi | 5–7 kW | £10,500–£13,500 | £1,500–£4,500 |
| 3 bedroom semi or small detached | 6–9 kW | £12,000–£15,500 | £3,000–£6,500 |
| 4 bedroom detached | 8–12 kW | £14,000–£18,000 | £5,000–£9,000 |
| 5+ bedroom or larger older house | 11–16 kW | £16,500–£22,500 | £7,500–£13,500 |
Installed, inc VAT: unit, cylinder, controls, minor pipework and commissioning. The £9,000 Boiler Upgrade Scheme figure applies to oil and LPG replacements in England and Wales installed from 21 July 2026 to 31 March 2027.

Replacing an oil or LPG boiler with a heat pump questions
Is a heat pump cheaper to run than oil?
It depends on oil prices, your home's insulation, the flow temperature and your electricity tariff, so there is no single answer. At the October to December 2026 price cap, a heat pump with a seasonal efficiency of 3.0 delivers heat for about 8.8p per kWh, and at 3.5 about 7.5p. Compare that with your oil cost per kWh of heat, allowing for your boiler's efficiency; the survey estimate gives a figure for your home.
Will I need bigger radiators in an older cottage or farmhouse?
Often in some rooms, because thick solid walls and older windows lose more heat, and heat pumps work at lower water temperatures than oil boilers. The survey checks each room. Rooms with high ceilings or large windows are common candidates for a larger radiator. Where swapping radiators is impractical, a high-temperature unit can be considered, with lower efficiency as the trade-off.
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.
Do I have to remove my oil tank?
Not always, but it should be emptied and made safe. A tank in good condition can be drained, cleaned and left in place, though most owners prefer to have it taken away to free up space. Old or damaged tanks are usually removed. Your quote says which option is included, and any remaining oil and sludge is disposed of properly.
