In an emergency

To call a rescue team

Call 999 for ‘Police’ – Mobile calls may go to the wrong Police force so say which county you are in!
Ask for the Police then Mountain Rescue
Say where you are (give description & grid reference) – consider downloading OS locate or similar to a smartphone (carry spare battery or power pack)
Describe the problem (and answer any other questions)
Stay by the phone or where your mobile works (keeping the line clear so you can be called back. The rescue team will call other services as needed)
