Havant announced Jackson Civil Engineering's appointment on 26 June 2026 for Langstone's one-kilometre coastal-defence scheme. The UK6 selected value is GBP 14 million excluding VAT, GBP 16.8 million including VAT; the council describes a separate GBP 23.6 million overall programme. Coastal Partners' August update retains an April 2027 main start and an intended shorter programme under refinement. Signed terms, final consent documents, approved programme and defence acceptance remain outstanding.

Owner-confirmed appointment and later programme refinement

Havant's June announcement names the appointed contractor and reports conditional committee approval. The UK6 records the selected value and pending award; the August owner account reports programme refinement and limited enabling works. Final planning, licence and signed-term documents have not been obtained.

Five frontages, tidal access and preconstruction planning

Sheet piles, concrete walls, flood glass and gates must be integrated with a tidal frontage, the A3023 access to Hayling Island, public routes, listed buildings and protected harbour habitats. Concurrent working across five frontages changes the coordination demands for access, utilities, deliveries and temporary works. Jackson is preparing construction and traffic plans for the required reviews and condition discharge.

Evidence conclusion

Appointed contractor, selected value and outstanding conditions

The owner appointment supplements the original UK6 record, whose award remains pending with a scheduled signature and estimated administrative dates. The August owner account reports limited vegetation clearance and supervised reptile relocation, while main defence works remain planned for April 2027. The intended under-one-year programme is being refined; the earlier 2027 and 2028 seasons remain programme history. The final decision and licence documents, executed NEC4 terms, approved target cost and programme, installed quantities and acceptance are outstanding.
