The £9,000 Oil and LPG Heat Pump Grant is Live Now – But Only Until 31 March 2027
Live
Higher rate ends 31 Mar 2027
Here's the news: the higher £9,000 Boiler Upgrade Scheme grant for eligible off-gas-grid homes is live now. It doesn't last forever. The higher rate is available until 31 March 2027.
In this short update, we explain what's changed, who actually qualifies, and why South West off-grid homes are well placed to benefit. For full details, see our guide to the £9,000 heat pump grant for oil and LPG homes.
The grant
What's live now?
Since 21 July 2026, eligible off-gas-grid properties replacing an oil or LPG heating system can receive £9,000 towards an air source or ground source heat pump through the Boiler Upgrade Scheme (BUS).
How the grant reaches you
The grant is paid to your MCS-certified installer and taken off the quoted price. You don't have to pay the full installation amount or claim the grant back later. Simple Solar is MCS-certified for heat pump installations and handles the voucher application as part of the process.
Eligibility
Who actually qualifies for £9,000?
It's not simply a grant for "anyone on oil". Three things have to line up together.

Three for three? A free survey confirms it properly.
The property also can't be a new-build, and the other standard Boiler Upgrade Scheme rules still apply.
South West
Why Devon, Cornwall and Somerset?
The South West has one of the highest concentrations of off-gas-grid homes in England. Many rural properties were never connected to mains gas.
Those households often face higher and less predictable heating costs than gas neighbours. Oil and LPG track global markets and sit outside the energy price cap.
Off-gas-grid heartland
- Cornwall
- Devon
- Somerset
For these homes, a properly designed air source heat pump plus the higher grant is worth a serious look before the £9,000 rate ends.
Example costs
What might it cost after the grant?
Simple Solar's air source heat pump installations start from around £12,000 before the grant.
| Grant · paid to installer | You pay | |
|---|---|---|
| Oil / LPG rate £9,000 grant | £9,000 | £3,000 |
| Standard rate £7,500 grant | £7,500 | £4,500 |
So, for an eligible off-gas-grid home replacing oil or LPG, the final price to the customer is around £3,000, after the £9,000 grant. With the standard £7,500 grant for non oil / LPG homes, it would be around £4,500.
Please note: this is an illustration only. Final price and running costs depend on the property, system design and how you use energy. A survey gives you a fixed-price quote with the correct grant deducted.
Don't leave it too late
Why act before 31 March 2027?
Two practical reasons.
The higher rate is time-limited
The higher £9,000 rate is time-limited. After 31 March 2027, eligible oil and LPG off-grid homes are expected to fall back to the standard £7,500 tier for air-to-water and ground source heat pumps (unless policy changes again).
Installation slots take time
Autumn and winter are busy for installers. Surveys, Ofgem consent checks and installation slots take time. Leaving it to the last minute is a good way to miss the diary – and possibly the higher rate.
What has to happen before install day
What to do next
Start with a free survey.
If your home is off the gas grid in Devon, Cornwall or Somerset and you currently heat with oil or LPG, the simplest first step is a free survey.
We'll confirm whether you are eligible for the £9,000 rate, recommend the right system, and give you a fixed-price quote with the grant already deducted.
