Heat Pump Grants UK 2026: Boiler Upgrade Scheme £7,500 Explained

Heat Pump Grants UK 2026: What the £7,500 Boiler Upgrade Scheme Actually Means for You

If your gas boiler is creaking towards retirement and you have caught even a whiff of the heat pump conversation, you have probably also heard about a government grant that takes a sizeable chunk off the upfront cost. That grant is real, it has just been expanded, and 2026 is arguably the most generous and the most accessible year the scheme has ever offered. The headline number is £7,500 off an air-source or ground-source heat pump in England and Wales, paid through the Boiler Upgrade Scheme (BUS) and deducted directly from your installer’s quote. For homes still running on heating oil or LPG, that figure is rising temporarily to £9,000 from summer 2026.

This guide is written for the UK homeowner sitting at the kitchen table, looking at a £2,500 gas boiler quote and wondering whether the grown-up move is actually a £10,000 heat pump after the grant lands. We will walk through what the BUS is, exactly how much it pays in 2026, who qualifies after April’s rule changes, how the application works behind the scenes, what a real installation costs today, and whether the running costs genuinely beat gas at the current Ofgem price cap. We will also cover the equivalent schemes in Scotland, Wales and Northern Ireland, name the installers worth getting a quote from, and demolish the most stubborn myths still floating around. By the end you should know whether a heat pump is right for your home and what claiming the heat pump grant UK 2026 actually involves.

What Is the Boiler Upgrade Scheme (BUS)?

The Boiler Upgrade Scheme is the UK Government’s flagship subsidy for low-carbon heating in England and Wales. Funded by the Department for Energy Security and Net Zero (DESNZ) and administered by Ofgem, it launched in May 2022 and was originally set to run for three years. Strong demand, particularly through 2024 and 2025, pushed the Government to extend the programme and increase the grant amount. Under the BUS (England and Wales) (Amendment) Regulations 2026, which came into force on 28 April 2026, the scheme has now been extended to 2030 and the eligibility rules have been substantially relaxed.

The mechanics are pleasingly simple. You do not apply yourself, fill in forms or send in receipts. Your chosen installer — who must be MCS-certified — applies to Ofgem on your behalf, the grant value is deducted from your quote up front, and Ofgem reimburses the installer once the work is signed off. From your point of view, you simply see a cheaper invoice. The 2025/26 budget for the scheme has been confirmed at £295 million, reflecting the Government’s confidence that heat pump uptake will continue to accelerate.

How Much Is the Heat Pump Grant in 2026?

For the majority of homeowners, the BUS pays a flat £7,500 towards the cost of installing an air-to-water air source heat pump, a ground source heat pump or a water source heat pump. That single figure is what most people are referring to when they talk about the heat pump grant. Biomass boilers — restricted to rural off-gas properties — attract a smaller £5,000 grant.

The April 2026 amendments introduced two important additions. First, air-to-air heat pumps (essentially split-system units that heat and cool air directly rather than feeding radiators) are now eligible at a lower tier of £2,500. Second, and more significant for many rural households, the Government announced that from July 2026 until March 2027 the grant for air-source and ground-source heat pumps will rise temporarily to £9,000 for homes and small businesses in England and Wales that currently rely on heating oil or LPG. That extra £1,500 is designed to push off-grid households — who tend to pay the highest fuel prices — towards electrification.

On top of the grant itself, the Treasury’s 0% VAT on the supply and installation of domestic heat pumps continues to apply until March 2027, knocking a further 20% off pre-tax labour and equipment costs.

Who Is Eligible for the BUS Grant?

Eligibility was the area where the scheme used to lose the most applicants. The 2026 reforms have stripped away most of the friction. The current rules are these. The property must be in England or Wales — Scotland and Northern Ireland run their own programmes, which we cover further down. You must own the property, whether you live in it yourself, rent it out as a private landlord, or run a small business from it. New-build homes are excluded, with a small carve-out for self-builds. The system being replaced must be a fossil-fuel boiler (gas, oil or LPG) or, in some cases, electric storage heating.

The single biggest change in April 2026 was the removal of the EPC requirement. Until then, applicants needed a valid Energy Performance Certificate showing no outstanding recommendations for loft or cavity wall insulation. That rule alone disqualified an enormous number of older homes and sent many homeowners off on expensive insulation detours before they could even apply. As of 28 April 2026, the BUS (Amendment) Regulations scrapped the EPC requirement entirely and removed the rule that loft or cavity wall insulation had to be in place first. You can now apply for the grant without an EPC and without prior insulation works, which has opened the scheme to a meaningfully wider pool of homeowners — particularly those in older terraced and semi-detached housing stock.

The grant is capped at one per property and the installation must be designed to meet 100% of the property’s space heating and hot water demand, so hybrid gas-and-heat-pump systems are not eligible for the full headline grant.

How to Apply (Step-by-Step)

The application process is one of the more user-friendly aspects of UK energy policy, mostly because you barely have to do anything. The steps are as follows.

Start by getting at least three quotes from MCS-certified heat pump installers. You can find certified firms using the MCS “Find an Installer” search at mcscertified.com or by calling their helpdesk. Quotes should include a heat loss survey, equipment specification, and a clear statement that the £7,500 grant value has been deducted from the total. If an installer is not MCS-certified, walk away — without that accreditation they cannot legally apply for the grant on your behalf.

Once you have chosen your installer and signed a contract, they will submit the BUS voucher application to Ofgem through the dedicated installer portal. Ofgem will then contact you directly — usually by email or phone — to confirm that the installer is genuinely acting on your behalf and that you understand what is being installed. This anti-fraud check is brief but mandatory.

Your installer then carries out the work. Once the system is commissioned and the MCS certificate is issued, the installer redeems the voucher and Ofgem pays the £7,500 directly to them. You pay only the net invoice. Ofgem may also conduct a random audit or site visit. The official entry point if you want to read the government’s own guidance is gov.uk/apply-boiler-upgrade-scheme.

Total Cost of Installing a Heat Pump UK 2026 (With Example Numbers)

Sticker prices for heat pumps still cause occasional sharp intakes of breath, but the after-grant economics have shifted significantly over the last two years. A typical air source heat pump installation in 2026 costs between £8,000 and £14,000 before the grant for a normal three- or four-bedroom home, with detached properties or those needing extensive radiator upgrades nudging towards £16,000. Ground source heat pumps remain considerably more expensive — usually £20,000 to £35,000 — because of the groundworks involved.

After the £7,500 BUS grant lands, most homeowners pay somewhere between £500 and £8,500 out of pocket for an air source system. For an average semi-detached home, a realistic working figure is around £4,500 to £6,000 net. Octopus Energy, currently the largest single heat pump installer in the UK, reports a median post-survey price of £4,459 after the grant for installations between September 2025 and February 2026 — and confirms that 91% of their quotes come in below the UK national average. Some smaller homes with straightforward installations are seeing net prices close to £1,000.

By way of example, a typical 7kW air source heat pump for a three-bedroom semi-detached home in the Midlands might be quoted at £11,500 gross. After the £7,500 grant the homeowner pays £4,000. Because the 0% VAT rate already applies to the equipment and labour, there is no further tax to add. That figure is broadly comparable to replacing a gas boiler with a high-end model and updating the system pipework — and it leaves you with a heating system that should last 15 to 20 years.

Heat Pump Running Costs vs Gas Boiler: Will I Actually Save Money?

This is the question that derails more kitchen-table conversations than any other, and the honest answer in 2026 is: it depends on your tariff, but for most well-installed systems, yes — modestly. At the April 2026 Ofgem price cap, electricity sits at roughly 24.5p/kWh against gas at around 6.4p/kWh — a ratio of just under four to one. Because a well-designed air source heat pump achieves a seasonal coefficient of performance (SCOP) of 3.5 to 4, it delivers around 3.5 units of heat for every unit of electricity consumed, which broadly cancels out the price differential.

In practical terms, an average three-bedroom UK home consumes roughly 11,500 kWh of heat per year. On the April 2026 price cap, that translates to an annual heating bill of around £835 on a modern A-rated gas boiler and around £840 on an air source heat pump at SCOP 3.5 — effectively at parity. Switch to a dedicated heat pump tariff, however, and the maths changes sharply. Octopus Cosy, OVO Heat Pump Plus and similar tariffs offer cheap electricity windows specifically timed to when your heat pump is heating water or pre-warming the house. Households on these tariffs typically save £100 to £300 per year compared with running a gas boiler, with savings of 20% to 35% on heating energy costs reported by Octopus’s own customer data.

If you are also looking at the broader picture of household bills, our guides on the Ofgem energy price cap for April 2026 and how to cut your energy bills in 2026 are worth reading alongside this article. Over the 20-year design life of a heat pump, Energy Saving Trust modelling suggests typical savings of around £3,900 against gas — and those numbers improve further if electricity decarbonises more quickly than gas, which is the central assumption of UK energy policy.

Heat Pump Grants in Scotland, Wales and Northern Ireland

The Boiler Upgrade Scheme covers England and Wales only, but the other UK nations have parallel offers that are in some respects more generous.

In Scotland, Home Energy Scotland offers a grant of up to £7,500 towards a heat pump installation, with an additional optional interest-free loan of up to £7,500. Rural and island households qualify for a £1,500 “rural uplift”, taking the grant to £9,000. Combined, a Scottish homeowner can access up to £16,500 of state-backed funding — half as a non-repayable grant, half as a zero-interest loan. The grant is administered by Home Energy Scotland on behalf of the Scottish Government, and the application route is again via an MCS-certified installer.

In Wales, the BUS itself applies, so any Welsh homeowner can claim the same £7,500. On top of that, the Welsh Government’s Warm Homes Nest scheme provides free energy-efficiency measures, including heat pumps, to lower-income households who meet a benefits-and-health-condition test. The two schemes can in principle be combined, dramatically reducing or eliminating the upfront cost for eligible Welsh households.

Northern Ireland sits awkwardly outside all of these programmes. There is no equivalent to the BUS in Northern Ireland. Instead, the Northern Ireland Sustainable Energy Programme (NISEP) offers targeted grants for energy-efficiency measures — including some air source heat pump installations — for households meeting an income test (broadly, total income under £38,000). The Housing Executive’s Affordable Warmth and Boiler Replacement schemes also run, though they are narrower in scope. If you are a Northern Ireland homeowner, your starting point should be the NI Direct energy efficiency pages.

Best Heat Pump Installers UK 2026

The UK installer market has matured significantly in the last two years and you no longer have to scour the parish noticeboard to find someone certified. The biggest players nationally are Octopus Energy, which now installs more heat pumps than anyone else in the UK and prices aggressively (median net price of around £4,459 after grant); British Gas, which has expanded its heat pump installation arm substantially in 2025 and tends to suit homeowners who value brand familiarity and a long-established service network; and EDF, which offers competitive packages particularly when bundled with its electric vehicle and solar offerings.

Below the big three sits a healthy ecosystem of regional specialists — firms like Heat Geek partner installers, BOXT, Aira and a long tail of independent MCS-certified engineers — many of whom will deliver better workmanship at a similar or lower price. The MCS database is the single source of truth. Get three quotes, ask each installer to walk you through the heat loss survey, and pay close attention to whether they are designing a “low flow temperature” system (better efficiency, possibly requiring larger radiators) or a “high temperature” retrofit that works with your existing radiators. Both can be valid choices depending on your home.

While you are reviewing your wider energy setup, it is worth running the numbers on switching your electricity supply at the same time. Our roundup of the best energy tariffs in the UK for 2026 highlights the heat pump-specific tariffs that can transform the running cost economics.

Common Heat Pump Myths Debunked

Despite the data, three or four myths refuse to die. They are worth taking head-on.

“Heat pumps do not work in cold weather.” This was true of early 1990s units. Modern air source heat pumps continue to deliver useful heat down to around minus 15°C and in some cases minus 25°C — temperatures the UK virtually never reaches. Consumer satisfaction surveys conducted during the cold spell of January 2026 found 85% of heat pump owners reporting good performance against 80% of gas boiler owners. Scandinavian countries, where winters routinely hit minus 20°C, have heat pump market shares above 60%.

“They are too noisy.” A modern air source unit operates at 40 to 60 decibels — roughly the sound of a domestic fridge. A DEFRA review found only around 100 noise complaints for every 300,000 installations, a complaint rate of 0.03%. You can stand next to a running heat pump and hold a normal conversation. Planning rules require units to be sited so that noise at the boundary is below specified limits.

“You cannot retrofit a heat pump into an old house.” You can, and an industry has grown up around exactly this. High-temperature heat pumps now deliver flow temperatures of 60 to 75°C, comparable to a gas boiler, meaning your existing radiators are usually adequate. Where radiators do need upgrading, it is typically only one or two on the coldest-facing rooms. The April 2026 removal of the insulation precondition means you no longer have to retrofit your loft before the heat pump goes in.

“They are always more expensive to run.” On the standard variable tariff, a heat pump and a gas boiler are now near parity for most homes. On a dedicated heat pump tariff, the heat pump wins clearly. As gas prices remain volatile and the carbon levy on gas is widely expected to rise, the running-cost trajectory favours electrified heating over the rest of the decade. Our analysis of UK energy bills falling in April and rising again in July 2026 gives a sense of where prices are likely to head next.

Frequently Asked Questions

Do I need planning permission for a heat pump? In most cases no — air source heat pumps are covered by Permitted Development Rights in England, Wales and Scotland, provided the unit is sited at least one metre from the property boundary and meets a noise limit at the nearest neighbouring window. Properties in conservation areas, listed buildings and flats may need full planning consent.

How long does the installation take? A straightforward swap onto existing radiators typically takes two to three days. A more involved retrofit with radiator upgrades or a hot water cylinder change can take four to seven days. You will normally be without heating for around 48 hours.

Can landlords claim the BUS? Yes. Private landlords are explicitly eligible for the £7,500 grant on their rental properties, and from April 2026 the removal of the EPC precondition has made this considerably easier to access.

Will I need a new hot water cylinder? Almost certainly, yes. Combi boiler systems do not have a cylinder, but heat pumps require one to store hot water at the lower flow temperature. A typical 200- to 250-litre unvented cylinder is standard and the cost is included in installer quotes.

How long do heat pumps last? Manufacturers typically guarantee 15 to 20 years on the unit itself, comparable to or exceeding the lifespan of a gas boiler. From 2026, MCS rules require installers to provide a six-year workmanship warranty backed by an Insurance Backed Guarantee.

Can I claim the grant twice if I move? No. The grant is tied to the property, not the homeowner. Each property can only receive one BUS grant.

The Bottom Line

For UK homeowners weighing up the next decade of home heating, the heat pump grant UK 2026 has quietly become one of the more compelling pieces of consumer policy on offer. The Boiler Upgrade Scheme pays a flat £7,500 (or £9,000 for off-grid oil and LPG homes from July 2026) directly into your installer’s account, the April 2026 reforms have removed the EPC hurdle that previously tripped up so many older homes, and the 0% VAT rate continues to chip another fifth off the bill. After grant and tax relief, the typical net cost of an air source heat pump installation now sits between £500 and £8,500 — territory previously occupied by a high-end gas boiler swap.

Running costs are at rough parity with gas on the standard variable tariff and meaningfully cheaper on a dedicated heat pump tariff, with the long-term direction of travel almost certainly favouring electrification. The honest caveats remain: heat pumps work best in homes that have at least some loft insulation, they need a competent installer who has done a proper heat loss survey, and they reward homeowners who pair the system with the right electricity tariff. Get those three things right, claim the grant the installer applies for on your behalf, and you should end up with a quieter, cleaner and increasingly cheaper heating system that lasts well into the 2040s. With the scheme now confirmed through 2030 and the eligibility rules at their most relaxed yet, 2026 is a notably good year to make the switch.
