The Topographical Assessment is one of the steps you’ll need to complete before getting your PCO licence and becoming a private hire driver in London. It catches some applicants off guard, but with the right preparation it’s very achievable. Most drivers who put the time in find it much more manageable than they expected.

Here’s what you need to know before you book.

What Is the Topographical Assessment?

If you want to become a private hire driver in London, TfL requires you to pass a Topographical Skills Assessment before your licence is approved. It’s a test of your knowledge of London: its areas, roads, landmarks and postcodes.

It’s nothing like the Knowledge of London that black cab drivers have to pass, which takes years of study. The Topographical Assessment is a computer-based multiple choice test. It requires real preparation, but it’s completely achievable for anyone who puts in a few focused weeks.

What Does the Test Cover?

London boroughs

You’ll need to know the 32 London boroughs, roughly where they are and what areas they cover.

Major roads

Key main roads, ring roads and motorway routes into London come up regularly. Knowing the road numbers and roughly where they run is worth focusing on.

Landmarks and places 

Airports, train stations, hospitals, sports venues, hotels and tourist attractions are all covered. If it’s somewhere a passenger might ask to go, it’s worth knowing where it is.

Postcodes

London’s postcode areas follow a clear pattern once you get the hang of it. Knowing which postcode covers which part of the city is tested directly, and it also helps you place everything else on the map.

Thames crossings

Bridges, tunnels and ferry crossings across the Thames come up often. There are more than most people realise before they start studying.

How to Prepare

Most drivers who pass first time spend two to four weeks preparing. Here’s what works:

Get a map

A physical or digital map of London is your best study tool. Spend time with it regularly rather than trying to take it all in at once. Geography sticks better when you keep coming back to it.

Use practice tests

There are free and paid resources online that work like the real TfL test. Going through practice questions regularly helps you get used to the format as well as the content.

Learn the postcode system

London’s postcode areas go by compass direction from the centre: N, NW, NE, E, SE, S, SW, W and EC/WC for the central zones. Once that clicks, it all gets much easier.

Start with what you know

If you’ve spent time in London, you already have a head start. Build out from the areas you’re familiar with rather than trying to learn everything from scratch.

Pay attention while you drive

If you’re already driving in London, notice the road numbers, borough signs and area names as you go. It adds up over time without any extra effort.

What to Expect on the Day

The test is taken at a TfL-approved test centre on a computer. It’s multiple choice, with a fixed number of questions and a time limit.

Bring your booking confirmation and valid ID. Once you’re at the screen, take your time with each question, pick your answer and keep moving. If you’re not sure on something, make your best guess and move on rather than spending too long on one question.

Results are usually confirmed on the day or shortly after.

What If You Don't Pass First Time?

You can retake the test. Most drivers who need a second attempt work out which areas they were weakest on and come back better prepared. The booking process for a retake is exactly the same.

If you do need to retake, give yourself proper time to review those weaker areas before you book again rather than rushing back in.

After You Pass

Your Topographical Assessment certificate is one of the documents you’ll need for your full TfL PCO licence application. Once you have it, along with your SERU certificate, medical report and Enhanced DBS check, you’re ready to submit your application and take the final steps towards your licence.

Once you’re licensed and ready to become a PCO driver, registering with Addison Lee is the natural next step for drivers who want consistent, quality work from day one.

Put the time in, prepare properly, and you’ll be fine. The assessment is straightforward when you’re ready for it.
