We would appreciate your cooperation
In support of Ordnance Survey's delivery of our Environmental Management System and Travel Plan, we encourage staff and visitors to use forms of transport other than the car, such as rail or coach. As a result, we only have limited visitor parking, which must be booked in advance through your contact at Head Office. We also seek to reduce the impact on the local residential community and, when spaces are not available on site, we actively discourage parking in neighbouring streets.
Should you require further information on how to find Ordnance Survey, please contact your host or the Customer Service Centre for details. Local rate HelpLine: 08456 05 05 05 (line open Monday to Friday, 8.30am to 5.00pm)
