What to do if you need urgent police help through the 999 service, but can’t speak:
If you’re in an emergency situation and need police help, but can’t speak, Make Yourself Heard and let the 999 operator know your call is genuine.
If making a sound would put you or someone else in danger and the BT operator cannot decide whether an emergency service is needed, your call will be transferred to the Silent Solution system. The Silent Solution is a police system used to filter out large numbers of accidental or hoax 999 calls. It also exists to help people who are unable to speak, but who genuinely need police assistance.
