How to Book the SERU Assessment (and What It Costs)
By SeruPass team — Independent SERU study app, fact-checked against TfL guidance
You don't book SERU the way you'd book a driving theory test on day one. It comes as part of your licence application, once TfL is ready for you.
When you can book
The order is:
- Apply for your London private hire driver's licence through TfL, with your DBS check and medical under way.
- Wait for TfL's review. Once your application has been reviewed, TfL contacts you and asks you to book your assessments — typically the topographical assessment, the SERU assessment and the English speaking and listening test (unless you're exempt).
- Book a slot using the instructions TfL gives you.
Our guide on how to get a PCO licence in London covers the whole application.
What it costs
At the time of writing, the SERU assessment costs £40 for your first attempt and £30 for a re-sit. Fees change, so confirm the current amount when you book.
On the day
- You take SERU on a computer at TfL's assessment centre.
- Bring the identification TfL asks for in your booking confirmation.
- Arrive early — being rushed costs you focus you'll need.
- It's open book, but timed: roughly an hour for around 36 questions. Here's how to use the handbook without running out of time.
Book when you're ready, not before
You get limited attempts, so only book once you're clearing the 60% pass mark comfortably in practice. Start with the free SERU practice tests.
Booking details and fees are set by Transport for London. SeruPass is an independent study app and can't book assessments for you.
