The Energy Bill [HL] 2022-23 originally trailed as the Energy Security Bill in the Queen’s Speech on 10 May 2022. It was introduced as the Energy Bill in the House of Lords on 6 July 2022 and then to the House of Commons on 25 April 2023 after completing Lord’s stages.
Copies of the Bill (as introduced, as brought from the House of Lords and debated in committee and as amended in Public Bill Committee) together with Explanatory Notes, Delegated Powers Memorandum and Impact Assessments are available on the Parliament website.
In addition, DESNZ has published 35 Energy Bill factsheets (updated as the Bill has changed) covering the various parts of the Bill.
The government’s Energy Security Bill overarching factsheet explained that the Bill “will deliver a cleaner, more affordable and more secure energy system for the long term”, building on the commitments in the April 2022 British Energy Security Strategy to “invest in homegrown energy and maintain the diversity and resilience of the UK’s energy supply”. The factsheet also highlighted the need for a “transformation of our energy system” and “more home-grown energy from more diverse sources which reduce our dependency on imported fossil fuels and our exposure to volatile and high prices in international markets”.
The Bill, as introduced in the House of Commons from the House of Lords, included a number of amendments added after government defeats, including clauses introducing a net zero target for the energy regulator Ofgem, banning any new coal mines in the UK, provisions on community energy and provisions on energy efficiency for buildings. The Library Briefing Energy Bill [HL] 2022-23: Overview, which was prepared for the Second Reading, provides an overview of the Bill and includes details of the clauses added to the Bill after defeats in the House of Lords. It also provides links to existing Commons Briefings on the Bill.

The Water (Special Measures) Bill was introduced in the House of Lords on 4 October 2024, and was amended at committee stage and report stage. It was introduced in the House of Commons on 27 November 2024, and its second reading is scheduled for 16 December 2024. The bill is intended to address poor performance from water companies.
Typical household energy bills increased by 54% in April 2022 and 27% in October 2022. Lower wholesale prices have led to falls in prices, but bills remain around 29% above their winter 2021/22 levels.
