A statement issued ahead of the company’s annual shareholder meeting revealed solid sales for support services, while increasing employment costs will mean that full year profits will be more weighted to the second half than usually.

Good momentum was said to have continued in equipment services across the UK, Middle East and Far East, helped by the changes after last year’s strategic review and benefiting from the global pick-up in infrastructure spend.

Interserve has secured a £65 million five-year contract with UK Support Services to provide facilities management and a one-year contract extension to provide total facilities management services to the Ministry of Justice worth £16m.

The business has also secured its place on the new £500m Private Investment Construction framework in the health sector and contracts worth in aggregate £77m to design and build four schools.

Trading at UK construction is more “mixed” but in-line with management expectations as they continue to working through some older, low-margin contracts.

Progress on contracts within its exited Energy from Waste business is in line with expectations, it added.

“There has, as yet, been little noticeable slowdown in our volume of work from UK government, although workflow may be impacted by the general election,” the company said.

Last year Interserve announced it is to pull out of the energy from waste business after a troubled Glasgow project contributed to a loss of more than £160 million.

Expectations for the overall performance and cash delivery are unchanged, with interim results scheduled for August 9.
