The Department for Energy Security and Net Zero has removed the previous version of the approved grant categories and values for the Boiler Upgrade Scheme, and states that the current version should be used from 21 July 20261. The change was made to the government page listing the scheme's approved standards, grant categories and grant levels, which applies to England and Wales1.
The page records that the approved grant categories and values for the scheme from 21 July 2026 were published on 28 May 2026, and that the details of grant categories and values in the notice were amended on 5 May 20261. The 21 July 2026 update removed the earlier version of those categories and values1. The page does not set out the individual grant categories or the amounts attached to them, and no figures for the current values have been reported on it1.
"Removed the previous version of the approved grant categories and values for the Boiler Upgrade Scheme. The current version should be used from 21 July 2026."
The same page carries the standards the Secretary of State has approved for Regulation 4 of The Boiler Upgrade Scheme (England and Wales) Regulations 2022, and the grant categories and grant levels approved for Regulation 131. A notice of standards and a summary of standards were published on 9 June 20261. Earlier updates listed MCS 007 Product Certification Scheme Requirements: Heat Pumps version 7, published 24 April 2025, and the Home Insulation and Energy Systems Contractors Scheme (HIES) Code of Practice Version Q, published 5 March 2025 and operational from 1 May 20251. Issue 2 of Microgeneration Installation Standard MIS 3005-D, the Heat Pump Standard (Design), was added on 3 December 20241.

Why it matters for households
The Boiler Upgrade Scheme is one of the main routes to public money for a home's heat pump or biomass boiler, so the categories and values that apply on a given date determine what a household can claim and for what. The page now points to a single current version of those categories and values, in place of the earlier version, which affects how the grant amount is established for applications made from 21 July 2026. Because the page does not reproduce the categories or the amounts, the specific figures in force from that date have not been reported here. Households weighing the scheme against other support can compare it with ECO4, and eligibility questions such as the EPC and insulation requirement and gas boiler eligibility sit alongside the values in deciding whether a home qualifies.
What happens next
The current version of the approved grant categories and values is to be used from 21 July 20261. No further dated steps are given on the page beyond that instruction1.
