How long is the police clearance certificate for?
Here's the relevant instruction:
"Date the certificate was issued
For the country where you currently live
The police certificate for the country where you currently live:
- must be issued no more than 6 months before the date you submit your application
- must not be expired
For any other country, the police certificate must be issued after the last time you stayed there for 6 months or more in a row.
Some countries put expiry dates on their police certificates. If you have a police certificate that expired, include it. We’ll accept it if:
- it was issued after the last time you stayed there for 6 months or more in a row
- it is not for the country where you currently live
