The SERU assessment is the test most new London minicab drivers worry about — and the one they are most likely to fail without preparation. Good SERU test training fixes that.

What Is the TfL SERU Assessment?

SERU stands for Safety, Equality and Regulatory Understanding. It has been a mandatory requirement for London private hire (PCO) drivers since 1 October 2021. It applies to new applicants and to existing drivers renewing their licence — but you only need to pass it once.

Since 1 April 2023, every new PHV applicant must pass SERU before TfL will grant a licence. There are no exemptions. If English is not your first language, you sit the same test as everyone else, although reasonable adjustments — for example for dyslexia — are available if you ask when booking.

SERU also does double duty. It covers the reading and writing part of TfL's English Language Requirement (ELR). The speaking and listening part is a separate 15 to 20 minute conversation, delivered with PeopleCert over a secure video or telephone link. Pass both and your English requirement is complete. To see where these assessments fit in the wider application, read our step-by-step guide to applying for a PCO licence.

The SERU Test Format: What to Expect on the Day

The TfL SERU test is computer-based. It is delivered by TfL staff at the TfL Driver Assessment Centre, under exam conditions. Every question comes from one source: the PHV Driver's Handbook.

You will face two question styles:

Good news: SERU is now open book. After a trial in 2024, TfL made the handbook available to refer to during the assessment. TfL has confirmed that the taxi driver version of SERU has 36 questions, a 60% pass mark and around 45 minutes. The private hire version is widely reported to follow the same format, though TfL has not published those exact figures for PHV drivers — treat them as a guide.

The Six Topics SERU Covers

TfL says the assessment covers six areas of the handbook:

  1. Your regulatory obligations, including the Equality Act
  2. TfL policies for private hire drivers
  3. The needs of passengers with protected characteristics
  4. Safeguarding children and adults at risk
  5. Passenger and driver safety
  6. Road and vehicle safety

TfL also strongly recommends completing its free online Safeguarding Awareness course before you sit SERU. Do it — it is free, and safeguarding questions catch out many drivers.

Why Do So Many Drivers Fail SERU?

In our experience, drivers fail for three main reasons:

The open-book trap: treat the handbook as a safety net, not a search engine. If you rely on flicking through it for answers, you will run out of time. Learn the content first, then use the book only to double-check.

SERU Test Practice That Works

Here is the preparation plan we use with our students:

  1. Read the PHV Driver's Handbook from start to finish. Every question comes from it.
  2. Complete TfL's free Safeguarding Awareness course. TfL strongly recommends it, and it covers one of the six topic areas.
  3. Take SERU mock tests until you score well above the pass mark, every time, under timed conditions.
  4. Drill complete-the-sentence questions. This is where second-language speakers lose most marks, so give it extra time.
  5. Book 1-to-1 training if your reading or writing feels weak. A trainer will spot your gaps far faster than you will.

Practise Anywhere With Our 24/7 SERU Mock Test Platform

You do not need to wait for a classroom session to practise. Our SERU practice platform at seru.pcotesttrainingcentre.com is available 24/7 on the web, Android and iOS. It gives you SERU mock test questions in the same style as the real assessment — multiple choice and complete-the-sentence — so you can build speed and confidence on your phone, at home or between jobs.

Booked your test? Turn up. Missing a confirmed SERU booking without a valid reason can lead to TfL enforcement action, including revocation. If you need reasonable adjustments, such as extra support for dyslexia, request them from TfL when you book.

Frequently Asked Questions

How many questions are in the TfL SERU test?

TfL has confirmed 36 questions, a 60% pass mark and around 45 minutes for the taxi driver SERU assessment. The private hire SERU is widely reported to follow the same format, but TfL has not published exact figures for it, so treat these numbers as a guide and check your booking confirmation.

Is the SERU test open book?

Yes. Following a trial in 2024, the PHV Driver's Handbook is available to refer to during the SERU assessment. But time is limited, so you cannot look up every answer. Drivers who pass first time know the handbook well and only use it to double-check.

How much does the SERU test cost?

The SERU assessment costs £40 for your first attempt and £30 for a resit at 2026 rates. You are eligible for one resit. Always check TfL's current fees before booking, as they can change.
