The company plans to add a new wing to its landmark plant in Uddingston , adding a further 30 jobs to the current 532 strong payroll.

The new three-storey extension will house production equipment and help boost the numbers of their famous treats.

Plans have been submitted to South Lanarkshire Council revealing details of the 1,900m2 extension with councillors due to make a decision in due course.

Tunnock’s said: “The current proposal is to extend Tunnock’s existing bakery in central Uddingston to the rear, to create 1,900 m² of additional space over two floors to accommodate new production equipment and increased production of existing product ranges.

“This proposal will future proof the present factory to accommodate increased worldwide demand for Tunnock’s products.

“The effect of the proposed extension is to allow new and improved equipment to be installed.

“This additional investment of several million pounds into the existing bakery premises will additionally safeguard current employment on the site.

“It is expected that 30 new jobs will also be created as a result of the proposed extension, and these will be created on the night shift.”

Tunnock’s was established in 1890 and the factory has been on the current site for more than 50 years.
