Ofgem

What they do

Ofgem (Office of Gas and Electricity Markets) is the UK's independent energy regulator and a non-ministerial government department [2, 3]. They work to protect energy consumers, regulate markets, and drive the transition to a Net Zero energy system [2, 3].

Welsh presence

Ofgem has a major, established office in Cardiff [2, 3]. Their recent job advertisements explicitly state that they "especially welcome applicants from Cardiff and Glasgow," indicating a strategic push to build out their regional hubs outside of London [6, 8, 9].

Tech hiring signal

There is a very strong and diverse technology, data, and product hiring signal in Cardiff [4, 5, 8, 9, 10, 11]. Recent open vacancies include:

- Senior AI Data Scientist [11]

- Senior Product Manager [10]

- Head of Data Research Unit [8]

- User Researcher [9]

- Data & AI Delivery Specialist [4]

- Digital Graduate Programme [2, 5]

Agency approach

As a UK government department, Ofgem is bound by public sector procurement rules. They will almost certainly mandate the use of Crown Commercial Service (CCS) frameworks (such as Public Sector Resourcing, Digital Outcomes and Specialists, or G-Cloud) for any external agency recruitment or contract hiring.

Recent timing signals

Multiple tech, data, and product roles were actively advertised in April 2026, showing ongoing digital transformation and regulatory systems development [9, 10].

Verdict

**priority_contact**. Ofgem is a major direct employer with a significant and growing digital/data presence in Cardiff. While recruiters will need to navigate public sector frameworks to do business with them, the volume and quality of tech hiring make them a top-tier target in South Wales.
