We have adopted the National-Government-issued Statutory Guidance on Convictions via a “Fit & Proper Person Policy".

If you have convictions or relevant matters, you must check the periods applied to offences thoroughly. No conviction is ever spent for private hire driver applicants as a Rehabilitation of Offenders (Exceptions) Order applies - all offences must be disclosed.
If applicants falsely fail to declare or if they breach the current policy, then your application will either be refused or referred to a panel for determination only after completing a DBS and DVLA check.
