The Department for Energy Security and Net Zero (DESNZ) ^[1] is a ministerial department of the Government of the United Kingdom. It was established on 7 February 2023 by a cabinet reshuffle under the Rishi Sunak premiership. The new department took on the energy policy responsibilities of the former Department for Business, Energy, and Industrial Strategy (BEIS). ^[2]

The department's first Secretary of State was Grant Shapps; he was previously the final Secretary of State at BEIS. The current secretary is Ed Miliband.

The department is scrutinised by the Energy Security and Net Zero Select Committee. ^[3]

History

The department was established on 7 February 2023.

The creation of the new department was described by Downing Street as an opportunity to "focus on giving the UK cheaper, cleaner, more secure sources of energy – cutting bills, cutting emissions, and cutting dependence on international energy supplies." ^[4]

The London School of Economics's Grantham Research Institute on Climate Change and the Environment welcomed the creation of the new department saying that it "signalled a commitment to delivering net zero" and "showed that MPs on the right of the Conservative Party have failed to win the argument for weakening climate policy." However, the LSE warned that the new department would have to "persuade other departments and the Treasury to accelerate action on cutting greenhouse gas emissions across the economy outside the energy sector" to be effective. ^[5]

Responsibilities

The department's immediate priorities were outlined by the Prime Minister as follows:

• To maintain energy supplies, particularly during the winter.
• To reduce energy bills and lower inflation.
• To ensure the UK is on track to meet its legally binding carbon budgets and Net Zero commitments.
• To speed up significantly the delivery of network infrastructure and green energy.
• To improve the energy efficiency of UK homes, businesses and public sector buildings.
• To deliver a new Energy Bill by the end of the Parliament. ^[4]
