The Department for Energy Security and Net Zero added a list of grant categories and grant levels approved for the Boiler Upgrade Scheme to its published regulations page on 21 May 20241. The page, which applies to England and Wales, carries the standards and grant values approved under The Boiler Upgrade Scheme (England and Wales) Regulations 20221.
The documents on the page list two things: the standards the Secretary of State has approved for the purposes of Regulation 4 of the 2022 Regulations, and the grant categories and grant levels approved for the purposes of Regulation 131. The 21 May 2024 update is recorded in the page history as: "Added list of grant categories and grant levels approved for the Boiler Upgrade Scheme."1
"Added list of grant categories and grant levels approved for the Boiler Upgrade Scheme."
The page was first published on 1 April 20221. Its earlier update, on 8 May 2024, recorded that the list of standards had been updated with the approved codes of practice as required by Regulation 4(1)(j)1. Later entries in the page history record further changes: on 3 December 2024, Issue 2 of Microgeneration Installation Standard MIS 3005-D, The Heat Pump Standard (Design), was listed1; on 28 April 2025, the page was updated to list 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.
The page history also records entries dated after the 21 May 2024 addition: 5 May 2026, when details of grant categories and values in the Notice of approved grant categories and values were amended; 28 May 2026, when approved grant categories and values from 21 July 2026 were published; 9 June 2026, when the Notice of standards and Summary of standards were published; and 21 July 2026, when the previous version of the approved grant categories and values was removed, with the note that "The current version should be used from 21 July 2026."1 The page states it was last updated on 21 July 20261.
The specific grant categories, the grant levels in pounds, and the standards listed in the documents are not set out in the text of the page itself. The page links to a Notice of standards, a Summary of standards spreadsheet dated June 2026, and a Notice of approved grant categories and values1. The amounts payable under the scheme, and which technologies or measures fall into each category, have not been reported here.
Why it matters for households
The Boiler Upgrade Scheme is one of the main routes by which a household in England and Wales can get money towards replacing a fossil fuel heating system with a heat pump or, in some circumstances, biomass. The grant categories and grant levels are the formal list of what the Secretary of State has approved, so they sit behind the figures a householder or their installer sees when an application is made. For a home's energy independence, the practical point is that the approved list is a moving document: standards and values on this page have been amended and replaced several times since 2022, and the page states that the current version should be used from 21 July 20261. Anyone working from an older copy of the list may be working from a version that has since been removed.
What happens next
The page records that the previous version of the approved grant categories and values was removed on 21 July 2026 and that the current version should be used from that date1. No further dated steps are given on the page beyond the entries already listed.
