The above site mentions otherwise. Please read the snippet below:
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
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
