Since 21 July 2026, off-grid households on heating oil or LPG can claim £9,000 towards a heat pump, £1,500 more than the standard grant.

Key facts: the BUS grant for oil and LPG homes

Grant rose from £7,500 to £9,000 for off-gas-grid oil and LPG homes on 21 July 2026
The higher rate is temporary: it applies to voucher applications made up to 31 March 2027
Homes on mains gas stay at £7,500
Applications hit a record 8,150 in July, and August set a record for vouchers paid
The scheme itself is funded to 2029/30 with a £2.7 billion budget
The EPC insulation condition has been removed: you no longer need to clear insulation recommendations first

The £9,000 Boiler Upgrade Scheme grant is aimed at the homes that have the most to gain from a heat pump: those off the gas grid, burning heating oil or LPG. Around 1.7 million UK homes heat this way, most of them rural, though the grant itself only covers England and Wales. The extra £1,500 changed the sums enough to show up in the figures straight away. Applications from oil and LPG households rose 81% in the month after the increase, helped along by oil prices climbing after the 2026 Middle East conflict.

If you're on oil or LPG and weighing up a heat pump, this page covers what the grant pays for, the conditions, and the deadline most coverage leaves out. For the wider picture on types, costs and whether one suits your home, see our Heat Pumps UK guide.

What Is the Boiler Upgrade Scheme?

The Boiler Upgrade Scheme (BUS) is a government grant that cuts the upfront cost of replacing a fossil fuel heating system with a heat pump. Your MCS-certified installer applies for it and takes it off your quote. You never handle the money. You pay the balance.

It covers England and Wales, has been running since 2022 and is administered by Ofgem. There is no means test. These are the current grant levels:

What you installGrant
Air source (air-to-water) heat pump£7,500, or £9,000 for off-grid oil and LPG homes
Ground source heat pump£7,500, or £9,000 for off-grid oil and LPG homes
Biomass boiler (rural, off-grid homes)£5,000
Air-to-air heat pump£2,500
Heat battery£2,500

What Changed on 21 July 2026?

Current heatingGrant before 21 JulyGrant from 21 JulyChange
Oil, off the gas grid£7,500£9,000+£1,500
LPG, off the gas grid£7,500£9,000+£1,500
Mains gas boiler£7,500£7,500No change
Electric, coal or other fuels£7,500£7,500No change

Off-grid households are the most exposed to fuel price swings. Oil and LPG follow global markets and have no price cap, while gas and electricity bills are capped by Ofgem. The government sent leaflets to around 200,000 heating-oil households ahead of the change.

Demand followed. July was the scheme's busiest month on record with about 8,150 applications. August brought roughly 7,500, the second-highest, and a record 3,238 air-to-water vouchers paid, up 40% on August 2025.

Important: if you have mains gas central heating, the grant is £7,500 and hasn't changed. The £9,000 rate is only for homes off the gas grid that currently heat with oil or LPG.

Around 200,000 heating-oil households were sent a leaflet about the higher grant. If you didn't get one, an installer can still confirm whether you qualify.

Who Qualifies for the £9,000 Grant?

You need to meet all of these:

The property is in England or Wales. Scotland has its own scheme with similar support, covered below
You currently heat with oil or LPG and the heat pump fully replaces that system. Hybrid set-ups that keep a boiler don't qualify
The home is off the gas grid. That means no mains gas supply and no record of a gas meter at the address, and not on a heat network
It's an existing home, not a new build, and you own it. Landlords can apply for rental properties
An MCS-certified installer fits an MCS-certified air-to-water or ground source heat pump
The system is under 45kWth, which covers almost every house
The voucher application is made by 31 March 2027

The EPC insulation rule has gone. You used to have to clear any loft or cavity wall insulation recommendations on your EPC before you could get the grant. That condition was removed in April 2026. Insulation is still worth doing, because it means a smaller, cheaper heat pump. Our insulation guide covers what to do first.

The Deadline Most People Miss: 31 March 2027

The scheme runs to 2029/30, but the extra £1,500 does not. The £9,000 rate applies to voucher applications submitted between 21 July 2026 and 31 March 2027. After that, oil and LPG homes go back to £7,500 unless the government extends it.

Your installer can only apply for the voucher once you've had a survey and accepted a quote, and the run-up to a deadline is when installers are busiest. Working back from 31 March, the sensible plan is to get quotes this autumn and have a survey booked before Christmas. If your oil boiler is on its last legs, don't wait for it to fail in February.

How to Apply, Step by Step

You don't apply yourself. The installer does it. Here's the order things happen in:

1
Find an MCS-certified heat pump installer
Get at least three quotes. Use the quote options at the bottom of this page to start. The installer has to be certified, not just the product.
2
Get a home survey and quote
A proper job starts with a room-by-room heat loss calculation. An installer who quotes over the phone without surveying is a red flag. Ask whether any radiators need upgrading.
3
Your installer applies for the voucher
They submit the application to Ofgem. Ofgem will contact you to confirm you've agreed to it. A heat pump voucher is valid for three months, or six for ground source.
4
Installation and payment
Once the system is commissioned the installer redeems the voucher. You pay the quote minus £9,000 and receive your MCS certificate.

A typical air source heat pump installation costs £8,000 to £15,000 depending on the size of the house, the installer and how much of the existing system can stay. With £9,000 off, many oil and LPG homes are looking at a net cost between nothing and £6,000. Our heat pump costs guide breaks down where the money goes.

Running costs have moved in the heat pump's favour too. Under the October 2026 price cap, gas rose about 8.7% to 7.97p/kWh while electricity went up less than 1% to 26.32p/kWh, thanks to the VAT cut on domestic electricity. Oil and LPG stay uncapped. On a heat pump tariff such as Octopus Cosy, a heat pump can undercut both, and more so with solar panels covering part of the daytime load. The October price cap breakdown has the detail.

Heating systemTypical annual fuel costPrice volatility
Heating oil£1,200–£2,000+High. No price cap
LPG£1,500–£2,500+High. No price cap
Heat pump (smart tariff)£575–£1,200Lower. Ofgem capped

These are illustrative ranges for a typical three-bedroom house. To see your own numbers, use the heat pump savings calculator, and read are heat pumps worth it? for the cases where the answer is no. If the remaining cost is the sticking point, the Warm Homes Loan Scheme is designed to finance the balance after the grant at a subsidised rate, once lenders launch.

Scotland: A Different Scheme With Similar Support

The BUS doesn't cover Scotland. Scottish homeowners use the Home Energy Scotland Grant and Loan instead: a grant of up to £7,500 towards a heat pump plus an optional interest-free loan of up to £7,500. Rural and island homes get a £1,500 uplift, taking the grant to £9,000. Call Home Energy Scotland on 0808 808 2282 before you commit to an installer, because you have to apply before work starts.

Pairing a heat pump with solar panels improves the savings, because your own daytime electricity runs part of the heating.

Frequently Asked Questions

Can I get the £9,000 if I have a gas boiler?

No. The £9,000 rate is only for homes off the gas grid that currently heat with oil or LPG. Homes with a mains gas boiler get the standard £7,500.

When does the £9,000 grant end?

The £9,000 rate applies to voucher applications submitted between 21 July 2026 and 31 March 2027. After that, oil and LPG homes return to the standard £7,500 unless the government extends the uplift. The Boiler Upgrade Scheme itself is funded to 2029/30.

What counts as off the gas grid?

The property must have no mains gas supply and no record of a gas meter at the address, and it can't be connected to a heat network. A home that has a gas supply but uses oil for heating doesn't count.

Do I need to do insulation work first?

No. The requirement to clear loft and cavity wall insulation recommendations on your EPC was removed in April 2026. Insulating first is still a good idea because it lets you fit a smaller heat pump.

I heat with coal or electric storage heaters. Do I get £9,000?

No. Homes replacing coal, solid fuel or direct electric heating qualify for the standard £7,500. The higher rate is specific to oil and LPG.

Is there a grant for air-to-air heat pumps?

Yes, but it is £2,500, not £9,000. Air-to-air systems heat and cool rooms but don't provide hot water. The £7,500 and £9,000 rates are for air-to-water and ground source heat pumps that run radiators or underfloor heating.

How long does it take to get the grant?

Allow 6 to 12 weeks from first contact with an installer to a finished installation, depending on installer availability, the survey and product lead times. The grant paperwork is handled by the installer and adds little time. Demand is high, so get quotes early.

Can landlords apply for the BUS grant?

Yes. Landlords can use the grant for rental properties in England and Wales, and the same conditions apply as for owner-occupied homes.

How long is the Boiler Upgrade Scheme running?

The scheme is funded to 2029/30 with a total budget of £2.7 billion under the Warm Homes Plan. Only the extra £1,500 for oil and LPG homes has the earlier 31 March 2027 cut-off.
