Get a Grant Toward an Energy-Efficient Heating System¹

The UK government's heat pump scheme — the Boiler Upgrade Scheme — offers a significant government grant toward the cost of a heat pump installation. The amount depends on your current heating fuel, with grants of £7,500 or £9,000 available to eligible homeowners in England and Wales. 

The BUS grant is currently scheduled to run until 31 December 2027, making this a great time to invest in low‑carbon heating, though it could still be subject to change.

¹ grant available through the Boiler Upgrade Scheme, subject to eligibility and government criteria. Not all households will qualify.

Heat Pump Grant Amounts

The UK government's heat pump subsidy — the Boiler Upgrade Scheme — now offers two grant levels depending on your current heating fuel:

Oil boiler or LPG

£9,000

The £9,000 grant for oil and LPG households was introduced in April 2026. Learn how the Boiler Upgrade Scheme works.

Heat Pump Grant Eligibility: Who Qualifies?

Getting a £7,500 heat pump grant is simpler than you might think.

To qualify for the grant, you need to:

  • Own a home or small business in England or Wales
  • Be replacing a fossil fuel system (like a gas or oil boiler)
  • Have a valid Energy Performance Certificate (EPC) with no major recommendations for insulation
  • Install a heat pump with a capacity up to 45kW (which suits most UK homes)

To get the grant, your installation must be carried out by an installer certified by the Microgeneration Certification Scheme (MCS). Switch Together only works with MCS-accredited professionals, so you're covered.

How the Air Source Heat Pump Grant Works

Under the Boiler Upgrade Scheme, you could receive a £7,500-£9,000 grant towards the cost of installing a heat pump, if you are eligible. The grant is applied upfront and all handled by your installer—you don’t need to claim it back or repay it.

Note: Air-to-air heat pumps and air conditioning systems are not eligible for the government grant. The scheme covers air-to-water heat pumps (which provide central heating and hot water) and ground source heat pumps.

Almost. While the grant goes a long way, you may still need to cover:

  • Radiator upgrades (for top performance)

  • A new hot water tank (for better heat storage)

  • Insulation improvements (if needed)

After the grant, most homeowners pay between £3,000–£8,000, depending on their home and system needs. With Switch Together, you also get group-buying discounts,  making the switch even more affordable.  Our group-buying model helps reduce the cost of these extras, too, by securing better prices from trusted installers.

Frequently Asked Questions About The Heat Pump Grant

Can I apply if I already have a heat pump?
No, the scheme is only for replacing fossil fuel systems.
How long does the application take?
If you're eligible, your installer will handle the process, and it typically takes a few weeks.
Do I need to repay the grant?
No. The grant is a one-time government subsidy. It’s not a loan, and you don’t have to pay it back.
Can I combine the grant with other savings or offers?
Yes. If you go through a group-buying scheme like Switch Together, you can access exclusive discounts in addition to the government grant.
Can landlords apply?
Yes. Private landlords in England and Wales can apply, as long as the property meets eligibility criteria.
What if I already applied for another grant?
You typically can’t combine BUS with other government heating grants for the same installation—but group-buying discounts still apply.
When does the heat pump grant end?

The UK government's heat pump grant — the Boiler Upgrade Scheme — is currently confirmed to run until 31 December 2027. In April 2026, the government actually increased the grant for oil and LPG households, suggesting active commitment to the scheme.

Is the heat pump grant means tested?

No. The government's heat pump subsidy is available to all eligible homeowners regardless of income. There is no income threshold or financial assessment — eligibility is based on your property and heating system, not your earnings.

Can I get a grant for a ground source heat pump?
Yes. The Boiler Upgrade Scheme covers ground source heat pumps as well as air source heat pumps — both receive the same grant amount (£7,500 for most households, or £9,000 for oil/LPG properties). The same eligibility criteria apply.
