South East Water appealed Ofwat's PR24 Final Determination to the CMA, securing over £100m of additional funding in the March 2026 redetermination. Investing £2.1bn across AMP8 across Kent and East Sussex — the region's largest-ever capital programme. Key priorities include supply interruption reduction, network resilience and a new reservoir near Canterbury.
South East Water's £2.1bn AMP8 programme is its largest-ever capital investment. The CMA redetermination has added additional resilience funding on top of the original Ofwat allowance. The programme is shaped by severe water resource constraints and high climate change exposure in the region.
South East Water's successful CMA appeal, which secured over £100m of additional funding, means the company's AMP8 capital programme is larger than originally planned. The additional money is ring-fenced for resilience investment — specifically network resilience and new storage capacity. Suppliers with capability in reservoir construction, trunk main renewal and network interconnection should note this as an active opportunity area throughout AMP8.
South East Water runs procurement through Find a Tender (for above-threshold contracts) and its own supplier portal for pre-qualification and framework registrations. Specific AMP8 framework appointments are tracked by Water Industry Hub members.
South East Water publishes procurement opportunities through its own supplier portal and on Find a Tender (find-tender.service.gov.uk) for above-threshold contracts. Suppliers should register on both channels. South East Water also periodically runs pre-qualification questionnaires (PQQs) ahead of major framework procurements — registering on the supplier portal is the first step to receiving these.
Given South East Water's CMA redetermination outcome and the additional resilience investment secured, procurement activity in the 2026–2028 period is expected to be higher than the baseline programme. The reservoir project near Canterbury and major trunk main resilience works represent the largest individual contract opportunities.
