Ramboll appoints water lead: implications for UK and Ireland infrastructure teams

30 Second Briefing
Ramboll has appointed Simon Jefferson as water sector lead for the UK and Ireland, tasking him with heading its regional water practice and steering major programmes focused on sustainability and resilience in regulated networks. With 20 years’ senior commercial experience across client and contractor organisations and over a decade in a regulated water business, Jefferson will target closer engagement with utilities and regulators, stronger supply chain partnerships and clearer commercial value on complex water infrastructure schemes. The move signals Ramboll’s intent to expand its role as a key delivery partner on long-term water investment cycles.
Technical Brief
- Jefferson’s 20 years’ senior commercial experience span both client and contractor organisations in the water sector.
- Mandate explicitly includes driving “innovation” across key water programmes, not just incremental delivery improvement.
- Focus on “sustained growth and development” of Ramboll’s water team suggests scaling multi-disciplinary delivery capacity.
Our Take
Ramboll’s recent win of a place on the UK government’s £3.5bn CPS2 framework suggests that strengthening its UK & Ireland water leadership will be important for competing on large public‑sector infrastructure and resilience programmes.
Our database shows several recent UK & Ireland leadership appointments at Ramboll (for buildings advisory and now water), signalling a deliberate build‑out of regional sector heads rather than a purely project‑by‑project growth model.
Given Ramboll’s role in UK government‑commissioned studies on undergrounding transmission lines, a senior commercial water specialist in the same region positions the firm to offer integrated advice on corridor planning where linear energy and water assets intersect.
