The Boiler Upgrade Scheme 2026 is the most direct heat pump grant UK 2026 households can access. The homeowner applies through an MCS certified installer, and the £7,500 heat pump grant is deducted from the installation bill at the point of sale, with no means testing and no income cap. The real question is whether a heat pump is worth it UK 2026 once the full air source heat pump cost UK is understood, and the answer depends on the heat pump tariff UK households move to, the home's insulation level and the chosen installer.
How SwitchInsights analysed this: the SwitchInsights team combined Ofgem and Energy Saving Trust BUS grant 2026 data with 2026 installer pricing from Octopus, EDF, British Gas and E.ON Next, then rated each route on the SwitchPilot Score methodology before publishing.
What does the Boiler Upgrade Scheme cover in 2026?
The Boiler Upgrade Scheme (BUS) is administered by Ofgem with a £2.7 billion budget running to 2030. An air source heat pump UK install or a ground source heat pump grant replacing a gas boiler attracts £7,500, the heat pump grant for oil heating or LPG households reaches £9,000 from July 2026, and air-to-air units attract a smaller £2,500 award.
Boiler Upgrade Scheme eligibility: the property must be an existing home in England or Wales heated by a fossil fuel system, supported by a valid EPC issued within the last ten years, and the installer must hold Microgeneration Certification Scheme (MCS) accreditation. Scotland and Northern Ireland run separate schemes.
What is the heat pump installation cost UK 2026 after the grant?
The heat pump installation cost UK varies by property size. MCS certified installers quote £8,000 to £10,000 for a 1-2 bed home (5-6kW unit), £10,000 to £12,000 for a typical three-bedroom semi (7kW unit), and £12,000 to £14,000 for a 4+ bedroom home (11kW+ system). Labour, the hot water cylinder and commissioning are broadly fixed regardless of property size.
Typical net cost: 3-bedroom semi, 2026
Cost ranges reflect 2026 installer market data. Actual cost depends on a site survey, and households should obtain at least two MCS certified installer quotes before committing.
Which energy suppliers install heat pumps in the UK?
Several major suppliers now operate their own installation arms, bundling the unit and install with an ongoing tariff. The BUS grant applies whichever route the household chooses.
| Supplier | Net cost after BUS | Paired tariff | Notes |
|---|---|---|---|
| Octopus Energy | From £2,999 | Cosy Octopus (~14p off-peak) | The Octopus heat pump price is fixed across the UK and the operator runs the largest installer fleet, with Samsung and Mitsubishi units. |
| EDF Energy | £3,500-£5,500 | EDF Heat Pump Tariff | The EDF heat pump cost is quoted after survey and bundles installation and aftercare in one contract using Vaillant units. |
| British Gas | £4,000-£6,000 | Heat Power tariff | British Gas heat pump installations use Worcester Bosch units and integrate with the Hive smart controls platform. |
| E.ON Next | £3,500-£5,500 | E.ON Next Pumped | The E.ON Next heat pump service uses Mitsubishi Ecodan units, although regional coverage varies by postcode. |
Net costs are shown after the £7,500 BUS grant, based on published supplier pricing as of May 2026. Households should confirm current pricing directly with each supplier.
Heat pump running costs UK: how do they compare to a gas boiler?
On a standard electricity tariff, heat pump running costs UK are broadly comparable to a gas boiler. At Q3 2026 price cap rates, electricity is around 26p per kWh and gas around 6.4p, and a coefficient of performance of 3 to 4 narrows the heat pump vs gas boiler gap without always closing it on standard rates.
A dedicated heat pump tariff UK households can move to changes the picture materially. The Octopus Cosy tariff charges around 14p per kWh off-peak, when heat pumps do the bulk of their work, and annual savings of £600 or more versus gas are achievable for a typical three-bedroom home. The Energy Saving Trust projects a 20-year saving of around £3,900 versus gas.
The tariff is where the heat pump payback period UK shortens: moving to a dedicated heat pump tariff alongside the installation is the single most effective step for the running cost case. The SwitchPilot tariff tracker shows current off-peak rates from Octopus, EDF and E.ON Next side by side.

Common questions about the heat pump grant UK 2026
How much is the heat pump grant UK 2026?
The Boiler Upgrade Scheme provides a £7,500 heat pump grant for an air source or ground source heat pump in England or Wales, and a £9,000 heat pump grant for oil and LPG homes from July 2026. The installer deducts the grant from the invoice directly.
What is the heat pump cost UK after the grant?
A typical three-bedroom heat pump installation cost UK is £10,000 to £12,000 before incentives, falling to £2,000 to £4,000 after the BUS grant and the 0% VAT heat pump rate. Octopus advertises a fixed price from £2,999 for straightforward properties.
Is a heat pump worth it UK 2026 compared with a gas boiler?
Running costs are broadly comparable to gas on a standard tariff. On the Octopus Cosy tariff, annual savings of £400 to £800 are achievable depending on property size, and the Energy Saving Trust projects a 20-year net return of around £3,900 versus gas.
Should households use an energy supplier or an independent installer?
Supplier packages from Octopus, EDF, British Gas and E.ON Next offer a single point of contact and a clear price before survey, although unit choice is limited to that supplier's preferred manufacturer. A comparison quote from an independent MCS certified installer is advisable before committing.
What other heat pump incentives UK households can claim?
Households on income below £36,000 can apply for the Warm Homes Local Grant of up to £30,000 for heat pump and insulation. Scotland offers the Home Energy Scotland heat pump scheme with cashback up to £7,500 plus interest-free loans, and Wales offers the Nest scheme for lower-income households on EPC E or below.
Is my home suitable for an air source heat pump UK install?
Most existing UK homes are suitable. Performance depends on insulation level, radiator sizing and outdoor space for the external unit. An MCS certified installer will survey the property before any work begins, and homes on EPC D or below may benefit from insulation upgrades first.
