The £7,500 Voucher: Everything You Need to Know About the Boiler Upgrade Scheme

20 January 2026•5 min read

The transition from fossil fuel heating to low-carbon alternatives is a cornerstone of the UK's net-zero strategy. For property owners in England and Wales, the Boiler Upgrade Scheme (BUS) represents the most significant financial incentive to make this change. With the grant value now set at a generous £7,500, the scheme has become a powerful tool for homeowners and landlords alike, particularly in the context of the 2030 EPC C targets [1].This post provides a comprehensive guide to the updated BUS, covering the grant amount, eligibility, and the simple, installer-led application process.

The Financial Incentive: Up to £7,500

The most compelling update to the Boiler Upgrade Scheme is the increased grant amount, designed to make the initial cost of installing a heat pump more accessible.

Technology

Grant Amount (Voucher Value)

Air Source Heat Pump (ASHP)

£7,500

Ground Source Heat Pump (GSHP)

£7,500

Biomass Boiler

£5,000

This grant is not a rebate; it is a voucher that is deducted directly from the final installation cost, meaning the property owner only pays the remaining balance [2]. Furthermore, the government has committed a substantial budget to the scheme, with the Warm Homes Plan extending its availability until at least 2030 [1].

Eligibility: Who Can Apply?

The BUS is open to property owners in England and Wales, including homeowners, self-builders, and private landlords. Unlike some other grants, there is no income threshold for the BUS, making it widely accessible.

Property and System Requirements:

1.Replacement System: The grant must be used to replace an existing fossil fuel heating system (oil, gas, LPG, or electric) with a low-carbon alternative [2].2.Installer Certification: The installation must be carried out by an MCS-certified installer. This is a non-negotiable requirement, ensuring quality and compliance with industry standards.3.EPC and Insulation: The property must have a valid Energy Performance Certificate (EPC) with no outstanding recommendations for loft or cavity wall insulation [2]. This requirement strongly reinforces the "Fabric First" principle, ensuring that the home is thermally efficient before a new heating system is installed. If a property has an exemption for insulation (e.g., a listed building), it may still be eligible.4.Property Type: The grant is available for domestic properties, including houses and flats, as well as small non-domestic properties.

The Application Process: Installer-Led Simplicity

One of the most streamlined aspects of the BUS is that the property owner does not handle the application or the voucher claim directly. The process is entirely managed by the installer, simplifying the journey for the consumer.The process follows three simple steps:1.Find an Installer: The property owner contacts an MCS-certified installer to get a quote for the work. The installer will confirm the property's eligibility, including checking the EPC and insulation status.2.Installer Application: Once the quote is agreed upon, the installer applies to Ofgem for the BUS voucher on the property owner's behalf.3.Voucher Confirmation: Ofgem contacts the property owner to confirm that the installer is acting on their behalf. The voucher is then issued to the installer, and the grant amount is subtracted from the final bill.

Implications for Landlords

For private landlords, the Boiler Upgrade Scheme is an invaluable tool for meeting the forthcoming Minimum Energy Efficiency Standards (MEES), which require rental properties to achieve an EPC C rating by 2030 [1].•Multiple Properties: Landlords can apply for the BUS for multiple properties in their portfolio, provided each property meets the eligibility criteria.•No Income Test: The absence of an income test makes the BUS a straightforward option for all landlords, regardless of their personal financial situation or that of their tenants.•Meeting EPC C: Installing a heat pump, especially when combined with fabric improvements like insulation, can significantly boost a property's EPC rating, helping landlords future-proof their investments and ensure compliance with the 2030 deadline.The £7,500 voucher is a clear signal of the government's commitment to accelerating the adoption of low-carbon heating. By engaging with an MCS-certified installer, property owners can secure this substantial grant, reduce their carbon footprint, and enjoy a more energy-efficient home.
