Among the critical decisions postponed were the long-anticipated planning decision on the next stage of the Lower Thames Crossing, expected by 20 June, but now delayed until October by the present Government.

Other critical infrastructure projects requiring early decisions from a new Government include proposals for terminals at London Luton Airport and at the Port of Immingham.

The call to free 0n-hold major infrastructure comes amid deepening concern that the hiatus on critical projects could continue as the new Government reassesses its spending priorities.

Policy issues also put on hold include publication of the draft PR24 settlement in water, and the third Road Investment Strategy, while expected changes to the payment reporting regulations were also held up.

The Civil Engineering Contractors Association wants to see a clear plan of action for infrastructure in the next Government’s first 100 days, including statements of policy intent on areas such as energy, transport, water, skills, and employment.

The trade body is also called for a timetable for major fiscal events with fixed timelines for the next Autumn Statement, Budget and any future Spending Review.

CECA director of operations Marie-Claude Hemming said: “The formation of a new UK Government offers an opportunity to turn over a page in project delivery and get the economy firing on all cylinders once more.

“The success of the UK infrastructure sector rests on certainty of pipeline, clarity of policy, and close co-operation between industry and government.

She added: “All parties in the 2024 General Election have rightfully identified infrastructure delivery as a primary driver of economic growth and the backbone of a sustainable future.

“The UK’s contractors now stand ready to get spades in the ground on schemes across England, Scotland, and Wales, to turn manifesto plans into reality, and deliver the stronger Britain that we all want to see.”
