Labour supplier Hennelly’s, which was providing workers for Balfour Beatty at the King’s Cross regeneration scheme, has gone into administration.

Hurst Morrison Thomson has been called in as administrator and is understood to have made about 80 redundancies.

Some 40 workers from the agency, which had previously provided staff for Balfour on Heathrow Terminal 5, walked off the £115m King’s Cross scheme in north London earlier this year claiming they had not been paid for three weeks.

Balfour said its work at King’s Cross had been coming to an end before it went into administration. It said: “Balfour Beatty has executed a managed exit .”
