Since its last update in May, the firm said it had enjoyed continued robust trading in its Overbury business, with full-year profits now anticipated to significantly outstrip earlier predictions.

The construction division is also delivering ahead of expectations, with operating margins set to land firmly within 3.0% – 3.5%.

Revenue growth in construction is similarly forecast to beat prior expectations, pushing profits upward.

Morgan Sindall said all other divisions remain on track, confirming the entire group’s pre-tax profits will now “significantly exceed” initial estimates for the year.

The firm will unveil detailed half-year results on 29 July.
