30 Second Briefing
Former Sizewell C joint managing director Julia Pyke has been appointed executive chair of Agilia Infrastructure Partners, the consultancy advising on more than £100bn of UK infrastructure schemes. Agilia’s portfolio includes the Sizewell C nuclear power station using the regulated asset base (RAB) financing model, the Havant Thicket Reservoir in Hampshire, and the UK small modular reactor programme, with offices in London and Teesside. Pyke succeeds James Stewart, who recently led the government-sponsored Stewart Review into major infrastructure projects.
Technical Brief
- Regulated Asset Base (RAB) model, first applied on Thames Tideway Tunnel, underpins Agilia’s financing expertise.
- Agilia’s current advisory portfolio exceeds £100bn capex across energy, water, transport and defence schemes.
- Sizewell C experience brings end-to-end financing and development capability for gigawatt-scale nuclear construction programmes.
- Havant Thicket Reservoir involvement links Agilia to large earthworks, impoundment structures and long-term water security planning.
- Advisory role on the UK small modular reactor programme implies focus on fleet deployment, standardisation and regulatory interface.
- London and Teesside offices position the consultancy close to both Whitehall decision-makers and industrial supply chains.
- Stewart Review leadership by outgoing chair feeds directly into Agilia’s approach to major project governance and delivery models.
Our Take
With Agilia already advising on more than £100bn of UK programmes, bringing in leadership experience from Sizewell C signals that nuclear and other complex regulated assets are likely to become a larger slice of its London- and Teesside-centred portfolio.
The combination of backgrounds spanning Sizewell C, Thames Tideway Tunnel and Havant Thicket Reservoir aligns with a pattern in our infrastructure coverage where UK clients favour advisers who have delivered consented, long-duration projects through tight environmental and stakeholder regimes.
Given the UK’s small modular reactor programme is referenced alongside Sizewell C, this appointment suggests Agilia is positioning to capture advisory roles on next-wave nuclear schemes, which in our database have so far been dominated by a small group of established engineering consultancies.
