BUS grant eligibility — does your Reading property qualify?

Last reviewed: 14 May 2026.

In short

BUS eligibility runs on four tests: location (England and Wales only), property (owner-occupied or landlord-owned, existing or self-build — not developer-built new build, not social housing), technology and installer (MCS-certified heat pump fitted by MCS-certified installer), and funding history (no previous government heat-pump grant on the same property). The April 2026 amendment package — SI 2026/390 — removed the EPC requirement, added air-to-air heat pumps at £2,500, put MCS certification on a statutory footing, and extended the scheme to 2030. Listed buildings and conservation-area properties are BUS-eligible but face separate planning hurdles. Self-builders qualify under a specific carve-out. Rentals and second homes qualify on the same terms as primary residences. New builds sold by developers do not qualify. Most Reading homes now meet all four tests; the exclusions affect a narrow share of the housing stock.

The four eligibility tests

For BUS eligibility, your property needs a “yes” on all four tests:

Test	Required
Location	Property in England or Wales
Property type	Owner-occupied or landlord-owned; existing property or self-build; not developer-built new build; not social housing
Technology and installer	MCS-certified heat pump fitted by MCS-certified installer with a BUS Installer Account
Funding history	The property has not previously received BUS or other government heat-pump funding

The April 2026 amendment package loosened conditions on three of the four — only funding history is unchanged. The biggest single change was removing the EPC requirement, which was the most common reason properties were previously knocked out at application stage.

Where does your property qualify? England and Wales detail

BUS is the England-and-Wales scheme — administered by Ofgem on behalf of the Department for Energy Security and Net Zero, under the Boiler Upgrade Scheme (England and Wales) Regulations 2022 as amended.

If your property is in Scotland, you apply under the Home Energy Scotland Grant + Loan instead — currently up to £7,500 with a £1,500 rural uplift and an optional interest-free loan covering additional install costs.

If your property is in Northern Ireland, there is no current equivalent national heat-pump grant. The Renewable Heat Incentive closed to NI applicants in 2016; a replacement scheme has been under consultation but is not operative as of May 2026.

For UK-wide property owners, eligibility is per-property. A Scottish landlord with a Reading rental can claim BUS on the Reading rental; a Reading homeowner with a Scottish holiday home applies under HES for the Scottish property and BUS for the Reading one.

Owner-occupied, rental, second home — does it matter?

The applicant must own the property — but there is no primary-residence requirement. The eligible cases:

• Owner-occupiers — the standard case, and the majority of BUS applications
• Private landlords — properties you own and let to tenants, including standard residential tenancies, holiday lets, and HMOs
• Second-home owners — properties you own for personal use that aren’t your primary residence
• Self-builders — see the next section

The cases that don’t qualify:

• Tenants — only the property owner can apply. If you rent your home, you cannot claim BUS in your own right; you can ask your landlord to consider it.
• Social housing tenants and registered social landlords — social housing is excluded by design and is intended to be served by separate funding programmes.
• Park homes — generally not eligible, though some edge cases exist for permanent dwellings.

There is no limit on the number of properties one owner can BUS — one BUS grant per property, not per owner. A landlord with five rentals across England and Wales can claim BUS on each one separately.

New build, self-build, existing — the carve-outs

This is where the most homeowner confusion sits, because the rules carve out a specific case.

Existing residential properties are the standard case. The property must be completed and first-occupied before the heat pump install, and must have a fossil-fuel system being replaced — gas, oil, LPG, or direct electric resistance heating.

Developer-built new builds — not eligible. Properties built by a developer and sold to a buyer with the heating system installed are excluded from BUS. The reasoning: new-build properties are governed by Building Regulations and (from 2025) the Future Homes Standard, and developers are expected to fit appropriate low-carbon heating from the outset rather than relying on retrofit grants.

Self-build and custom-build properties — eligible under a specific carve-out. The conditions:

• The property was constructed primarily using the labour or resources of the first owner, or by a builder the first owner contracted directly
• The property has never been owned by a business or organisation
• First occupation falls on or after the heat pump commissioning date (this prevents new-build developer stock being reclassified as self-build through later resale)
• Title deeds prove ownership and construction
• Construction invoices evidence the build cost

A self-builder commissioning their own home and fitting an ASHP at first occupation can claim the £7,500 BUS grant. A developer building 30 homes and selling them with ASHPs installed cannot claim BUS on any of them — those installations are part of the new-build sale price, outside the BUS scope.

Self-builds are eligible for heat pumps (air-to-water, ground-source, water-source, air-to-air) but not for biomass boilers.

Listed buildings and conservation areas

Listed buildings and conservation-area properties are eligible on BUS terms — the scheme does not exclude them. What changes for these properties is the planning route, which runs separately from BUS.

Listed buildings require listed building consent for the heat pump install. The consent typically focuses on the visual impact of the outdoor unit, the route of any new pipework through listed fabric, and modifications to the existing heating layout. Reading Borough Council is the consent authority for Reading-area listed buildings; the application takes 8–12 weeks and the current fee is £206.

Conservation areas without listed status are subject to Article 4 Direction considerations. Most heat pump installs in conservation areas fall under permitted development with conditions:

• No installation on a wall or roof that fronts onto a highway
• No installation nearer to any highway than the closest part of the home
• Noise restrictions (the heat pump must comply with the MCS standard noise check at one metre from a neighbour’s habitable room window)

The MCS install standard (MIS 3005-I V3.0, current from December 2025) includes the same noise compliance check for all installations, but the planning enforcement layer is more active in conservation areas.

The implication for your BUS application: the BUS application proceeds normally — the installer applies, you give consent, the voucher issues. Planning consent runs in parallel as a separate workstream. Both must be in place before the install can start. If planning is refused, the BUS voucher remains valid through its 3-month (ASHP) or 6-month (GSHP) window, giving time for a re-application or design change — but if planning isn’t resolved before the voucher expires, the application is lost and a fresh BUS application is needed.

A competent installer will check the property’s planning status at the survey stage (listed, conservation area, Article 4) and quote accordingly. Our BUS application guide walks through the application timeline including how planning fits in.

On-gas vs off-gas — and the July 2026 £9,000 uplift

Both on-gas and off-gas-grid properties are BUS-eligible.

On-gas properties are the standard case — replacing a gas boiler at the £7,500 grant.

Off-gas-grid properties are also eligible at £7,500, with one important addition: from July 2026 (subject to a formal DESNZ grant change notice), properties currently heated by oil or LPG are expected to qualify for an additional £1,500 uplift taking the total to £9,000. The uplift covers air-to-water and ground-source heat pumps only — not air-to-air, not biomass. It is for the 2026/27 financial year only, expected to expire 31 March 2027.

For most Reading-area properties this uplift doesn’t apply — Reading is firmly on the gas grid and homes are replacing gas boilers. The uplift becomes relevant for properties on the rural fringes of West Berkshire beyond the gas network, and for any Reading homeowner with a second off-grid property.

One specific exclusion to flag: hybrid systems (existing gas boiler kept alongside a new heat pump) are not BUS-eligible. The grant requires the fossil-fuel system to be removed and replaced. The December 2025 MCS standard change permitting hybrid system designs at the design-standard level (MIS 3005-D V3.0) did not extend hybrid eligibility into the BUS regulations themselves — these remain distinct rule layers.

What BUS covers within the install (and what it doesn’t)

A common point of confusion. The eligible plant under BUS includes:

• The heat pump itself
• Pipework (primary and secondary heating circuits, new chases, replacement of inadequate existing pipework)
• Heat emitters — radiators, including upgrades from existing to larger units; underfloor heating where new-fit
• Hot water cylinders — the unvented cylinder typically required for ASHP installs; buffer tanks where the design needs one
• Heating controls — thermostats, weather compensation hardware, smart-control hubs
• Valves and isolators — system protection, magnetic filter, zone valves
• System cleaning — power flush, inhibitor

But “covered by BUS” doesn’t mean “free under BUS”. The £7,500 grant is a fixed amount deducted from the install quote up-front. Whatever the install costs above £7,500, the homeowner pays.

A typical Reading retrofit example: an install costing £12,500 in total (heat pump + cylinder + radiator upgrades + electrical works + commissioning) gets £7,500 deducted, leaving £5,000 for the homeowner. Our cost guide covers what shapes the total install cost and where the BUS lands within it.

What BUS does NOT cover, at all:

• Fabric insulation upgrades — loft insulation, cavity wall insulation, internal or external wall insulation, floor insulation. These are addressed under separate schemes (ECO4, HUG2, Warm Homes when operative). BUS is a heat-pump grant, not an insulation grant.
• EPC certificates — even where one is recommended
• Planning fees — listed building consent, conservation-area applications, Article 4 review fees
• Building Regulations applications
• Re-decoration — making good after pipework chases, repainting around new radiators, flooring re-laying

A clean BUS-eligible quote shows the £7,500 grant deducted from the heat-pump-and-ancillaries total. Anything outside that scope — fabric upgrades, planning, decoration — is paid for separately by the homeowner.

Radiator upgrades — the practical case. If your heat-loss survey (see our heat loss survey guide for what to expect) recommends three larger radiators to support a 45°C flow temperature, those radiator upgrades sit inside the BUS-eligible plant. The radiator costs (typically £200–£400 per radiator with labour) absorb into the install quote, the grant deducts from the total, the homeowner pays the post-grant balance.

What changed in April 2026

The April 2026 amendment package (SI 2026/390, in force 28 April 2026) was the largest single eligibility expansion since the £7,500 grant uplift of September 2023. Six material changes:

1. Scheme extended to 2030 — previously committed to 2028; now committed to 2030 with budget to match.
2. Air-to-air heat pumps added as a new technology category at £2,500. Previously these systems sat outside the scheme.
3. EPC requirement removed entirely — the requirement for a valid EPC less than 10 years old, with no outstanding loft or cavity-wall insulation recommendations, was struck. Alternative evidence (utility bill + photographs + expired EPC) is now accepted.
4. MCS certification placed on a statutory footing — the installer’s MCS certification requirement is now in the regulations themselves. An installer that loses certification mid-project cannot complete the application.
5. 2026/27 budget of £400 million confirmed.
6. Hybrid heat pump systems were defined at the MCS level (MIS 3005-D V3.0) but not extended into BUS — hybrids remain BUS-ineligible.

Properties that were previously blocked by the EPC requirement became newly eligible on 28 April 2026 — particularly older terraces in conservation areas where solid-wall insulation recommendations made BUS application impossible without first doing the insulation work.

What this means for homes in Reading

Most Reading homes are BUS-eligible under the post-April 2026 rules. The patterns worth knowing:

• Central Reading and lower Caversham — significant Victorian and Edwardian terrace stock, much of it in conservation areas. The EPC removal particularly helps these properties. Listed building consent or conservation-area planning consent runs as a separate workstream — material for the installer to flag at survey, not a BUS eligibility issue.
• Caversham Heights, Caversham Park, parts of central Reading — concentrations of listed properties. Eligible for BUS; planning route adds 8–12 weeks to the overall timeline.
• Tilehurst, Earley, Whitley, Woodley — inter-war and post-war suburban semi stock, mostly outside conservation areas, mostly cavity-walled. Straightforward BUS eligibility for the standard owner-occupied case.
• Lower Earley and the modern southern/western estates — 1980s+ construction. BUS-eligible on standard terms. Note: the most recent developer-built new-build phases are not BUS-eligible.
• Reading rental properties — eligible. Reading has a meaningful private-rental sector and landlords can claim BUS on let properties on the same terms as owner-occupied.
• Off-gas-grid Reading properties are rare but exist on the rural fringes. For these, the July 2026 £9,000 uplift applies if currently heated by oil or LPG — see our BUS application guide for the uplift mechanics.
• Self-build properties in Reading are unusual but not non-existent — typically on the southern fringe development sites. Title deeds and construction invoices required as evidence.

The eligibility-blocking categories in the Reading stock are narrow: developer-built new builds (the most recent phases in Lower Earley, some Caversham fringe developments) cannot claim BUS, and the small social-housing stock is excluded. For the vast majority of Reading-area homeowners considering a heat pump install, BUS is the standard route.
