Job description

About the Group

Enterprise and Growth Unit

The Enterprise and Growth Unit (EGU) promotes sustainable economic growth and higher productivity for the UK. We provide analysis and advice on enterprise, innovation, private sector investment and a cost-effective transition to a low-carbon economy. The Enterprise and Growth Unit has a varied and exciting agenda and we work closely with a wide variety of other teams across the Treasury.

We also work alongside other departments and government organisations to ensure that we are thinking creatively, spending wisely, and acting boldly to deliver these goals. These organisations are:

• the Department for Business and Trade,
• the Department for Energy Security and Net Zero,
• the Department for Environment, Food & Rural Affairs,
• the Department for Science, Innovation and Technology,
• the Department for Transport,
• the Department for Culture, Media & Sport,
• the Competition and Markets Authority,
• HM Land Registry, and
• UK Export Finance

About the Team

The Climate and Environment Team (CET) acts as the focal point for HM Treasury’s work on climate change, net zero and nature. The team leads on embedding domestic climate risk, net zero and environmental policy considerations into the work of the department. We work with teams in tax, spending, economics, trade, fiscal, financial services and financial stability to use the range of levers which Treasury controls to ensure the government has affordable and economically efficient plans to achieve its legal commitments under the Climate Change Act 2008 and Environment Act 2021.

We advance Treasury interests across some of the biggest policy opportunities and challenges facing the UK including climate mitigation and adaptation, decarbonising heat and buildings, water company regulation, waste sector reform, implementing England’s agricultural transition plan and reforming our domestic environment policy.

The team leads engagement with and spending control for the Department for Environment, Food and Rural Affairs (Defra) and works closely with the Department for Energy Security and Net Zero (DESNZ), Cabinet Office and No10 on the government’s overall climate change strategy and plan. We also support international colleagues in their efforts to galvanise global action on climate and nature.

We are a flexible and friendly team, and our members have a range of working patterns.

About the Job

We are advertising for a policy adviser role in the Defra spending team, which has spending control responsibility for the Department for Environment, Food and Rural Affairs and advises the Chancellor and HMT Ministers on all areas of policy within Defra’s remit, and that of its arm’s-length bodies.

The branch advises HMT ministers on Defra policy - including agriculture, rural affairs, nature, waste, water regulation and environmental regulation - and on ensuring government has economically efficient plans to deliver our statutory environmental targets and resilience to climate risk.

This is an exciting opportunity to be at the heart of government policy making and will give the postholder the opportunity to lead and shape policy in several of these areas, in a supportive environment that encourages innovation, independent thinking, and a focus on delivering value for the UK taxpayer.

You do not need to be a policy professional, have any specific qualifications, or prior experience/knowledge of these policy areas to apply for this role. We are looking for people who have the right set of skills for the role, who demonstrate the values of our organisation, and who are motivated to come and work with us on a range of issues that are key to the UK’s economic prosperity and resilience. These are stretching posts that will require you to develop expertise within the relevant policy areas.

Any previous experience in public spending or the relevant policy areas would be beneficial, however our ideal candidate would be someone who can influence a range of stakeholders, develop novel solutions to complex issues, and make evidence-based decisions where significant trade-offs need to be balanced. The postholder will be well supported by line management and the wider team, and training on spending control and reviewing business cases will be provided.

1. Lead on the delivery of the Environment Act Framework and Defra’s contribution to net zero in line with HMT’s objectives.

2. Lead on a number of environmental policy areas including waste and circular economy, trees and peat, air quality, and biodiversity. You will identify and promote HMT interests across a range of policy areas, with spending responsibility for £100s of ms. This will involve developing and maintaining relationships with colleagues in Defra and across Whitehall, working through spending and/or policy issues with autonomy and advising HMT ministers.
3. Lead on scrutinising and supporting Defra’s work to increase private finance into nature and adaptation. You will scrutinise and lead on providing spending control of Defra’s green finance package and engage with Defra green finance leads to support the mobilisation of additional private finance into nature to support delivery of environmental targets and goals.
