MARGINS edged up at Henry Boot's construction arm last year, which contributed just under half of the Yorkshire-based firm's £86.1 million turnover.
The workload was down from £108.8 million in 2003 as property deals were held up but social housing jobs in Doncaster and Bolsover came on stream to lift construction orders.
Managing director Jamie Boot said: 'Margins are improving.
'We have just started a Home Office framework for work on prisons and we are hoping that will be a good source of work for the next four or five years.'
The firm does not break out divisional figures but turned in a group pre-tax profit of £15.9 million.
