INTERSERVE, the infrastructure business that was sacked from Glasgow’s Polmadie energy centre in December, has posted a pre-tax loss of £94.1 million, after setting aside £160m to cover the costs of exiting the energy from waste business.

The group, which last month saw shares fall by third when it announced an increase in the exceptional charge, from £70m, has suspended its dividend to enhance liquidity.

Revenue at the group was constant at £3.2billion.

The company said growth from international business was offset by a modest decline in UK support services, as a result of delays in government procurement.
