Construction group Rok has expanded its Yorkshire operations by buying a local contractor for £4.8m.

ROK bought Harrison Construction, which employs 80 people, from parent company S Harrison Group.

Garvis Snook, chief executive of Rok, said: “This acquisition will enhance Rok’s operations in Yorkshire and facilitate the opening of a contracting business in the Sheffield area.”

Rok will now pay £2.4m in cash and £800,000 in shares for Harrison. A further £1.6m will be paid on completion of the deal.

The contractor, which is based in Malton, North Yorkshire, will then be integrated into Rok’s Northern operations.

Martyn Harrison, chairman of S Harrison, said: “Rok provides the right infrastructure for Harrison’s construction business to thrive.”

Harrison said the deal would allow the group to focus on its development interests and partner with Rok on schemes in Yorkshire.

The acquisition follows Rok’s purchase of another Yorkshire firm, Rotherham-based EMB Services, in February.

It has spent £60m on acquisitions since last September, including £31.3m on the construction arm of Scottish housebuilder Tulloch, and £21m on Midlands-based firm SOL Construction.
