# UK MoD Plans £500m Portsmouth Jetty Rebuild

The UK Ministry of Defence, through the Defence Infrastructure Organisation, is preparing a £500 million (excluding VAT) main works competition to replace Fountain Lake Jetty at Portsmouth Naval Base. The procurement remains at the market-engagement stage, not an award. The proposed works include demolition and reconstruction, dredging, utility changes, flood defences, access improvements, buildings, and support facilities; the main works contract is provisionally scheduled to run from 30 March 2028 to 31 December 2037.

- Contractors from NATO member countries may participate. The questionnaire deadline is **26 February 2027** (103 days from 15 November 2026); an industry event is planned for Q1 2027, and the formal tender is currently expected on 30 June 2027.
- Construction firms and specialist suppliers can use the market-engagement stage to assess the scope and prepare for a large, long-duration naval infrastructure competition. Relevant capabilities include marine construction, dredging, utilities, flood protection, and access works.
- The £500 million estimate excludes VAT. Companies should account for the stated project scale and provisional performance period when assessing teaming, capacity, and bid preparation.
