Ofwat amends Portsmouth licence to set a ten-year price control for Havant Thicket

Ofwat has altered Portsmouth Water’s licence to cater for a separate, ten-year price control for activities relating to the new Havant Thicket reservoir (simulation pictured), which will provide a cross-border supply to Southern Water.

Ofwat’s provisions include a revised price control mid-period, to apply from year six onwards, to enable a series of revenue or cost reconciliation adjustments to be applied in parallel to the 2024 price review.

It defined “Havant Thicket activities” activities as “(a) the planning, development, construction, operation and maintenance of the Havant Thicket reservoir and associated infrastructure or (b) the bulk supply to Southern Water that it facilitates”.

The modifications concern Condition B (charges) and Condition E (undue preference/discrimination in charges).
