SERU Mock
SERU for taxi drivers: what is different
There is a separate SERU for London taxi drivers, introduced from 1 October 2025. TfL says it has 36 questions, takes about one hour, has a 60% pass mark, and lets you use the handbook.
What TfL says
TfL Notice 06/25 introduced a SERU assessment for taxi drivers. It applies to licensed taxi drivers renewing a licence that expires on or after 1 October 2025, and to new Knowledge of London applicants.
- Questions: 36
- Time: about one hour
- Pass mark: 60%
- The taxi driver’s handbook is available during the test
It is not the same as the private hire test
TfL says passing the private hire SERU does not exempt anyone from the taxi SERU, because the two differ. The private hire test is based on the PHV Driver’s Handbook. The figures above are for taxis, not private hire.
What we cover
This site is for private hire (PHV) applicants. Our questions are written from the PHV handbook. They may help with general ideas such as safety, equality and safeguarding, but they do not match the taxi handbook. For taxi preparation use TfL’s own materials.
Where to read more
Read the TfL notice linked below. TfL also says the taxi test differs in other ways, so always check the latest notice before you book. We do not give licensing advice. For anything about your own licence, ask TfL.
