If you wish to print maps for map return purposes then you have two options:
1. Contact a mapping and data centre offering map return
Find your nearest Ordnance Survey Mapping and Data Centre
2. Use ‘The Planning Portal’
The one-stop-shop for planning and building services online. Using the Portal it is possible to submit a planning application, including site plans, and make payments to any authority that is willing to accept them (most authorities do).
