Rotherham or Barnsley, postal address is Barnsley but there's a welcome to Rotherham sign at the entrance to Cortonwood, l think that's their council trying to claim it back..
Cortonwood is definitely in Rotherham. The rates are paid to Rotherham council and any plans are submitted to Rotherham Council. The postal address is Barnsley and the postcode is S73 hence a lot of the confusion. Most of the retailers label their Cortonwood stores as ‘Barnsley’ or ‘Barnsley Cortonwood’. The main access road into the retail park is in Barnsley, however. When Morrisons opened they incorrectly invited the mayor of Barnsley to cut the ribbon or something like that. I know the former Wilko is being split into two smaller stores. Unsure if Hotel Chocolat will be one of those.
