How much does the TfL topographical assessment cost?

Current published fee: £40 first attempt, £30 resit

TfL’s current 2026 fee information lists the initial topographical assessment at £40 and a topographical resit at £30. Those are official assessment fees and are separate from optional independent training products.

Check the official TfL amount when you are invited

PCO Topography does not hard-code a TfL assessment fee into this guide because charges and arrangements can change. Use your current TfL invitation and TfL licensing information for the amount actually payable for your assessment or any retest.

Training cost is separate

Private training is optional and varies widely. Compare what you actually receive: static notes, classroom tuition, practice questions, interactive route plotting, access period and feedback. A lower price is not automatically better if the material does not match the skill you need to practise.

Budget for the possibility of a retest

If a retest is required, there may be another official charge as well as additional preparation time. That is one reason to practise the route-planning process before the assessment rather than relying on memorised answers.

PCO Topography pricing

The current PCO Topography prototype is designed around one free Cassland Road route followed by a one-off 90-day Pro access period. The final live price will be shown clearly before purchase.

Common mistakes when working on assessment budgeting

A common mistake is trying to solve assessment budgeting too quickly. Candidates can recognise the general area yet miss the first important restriction or connection. Slow the decision down long enough to explain why the first road choice works. That small pause is usually cheaper than repairing several later turns after the route has already moved away from the best corridor.

Another mistake is treating every visible difference from the accepted line as the same problem. With assessment budgeting, the useful question is whether the road sequence is wrong or the drawing is merely imprecise. PCO Topography separates those signals so you can prioritise separating official TfL fees from optional independent preparation costs. A route-choice correction should come before cosmetic line placement.

Finally, avoid memorising the shape of one map. Repeat the underlying decision on a different exercise. If you can explain the rule and apply it elsewhere, the skill is becoming transferable. That is why the route bank combines focused practice with full routes rather than asking you to repeat one screenshot until it looks familiar.

A practical study drill for assessment budgeting

Use a three-pass drill. On pass one, inspect the map without plotting and say the likely corridor aloud or write it down. On pass two, plot and submit normally. On pass three, review the first meaningful divergence from the accepted model and state the reason for it in one sentence. This keeps the session focused on decisions instead of random repetition.

For the next attempt, change only the behaviour that caused the main error. If the issue was direction, check arrows earlier. If it was a structure, verify the actual connection. If it was road position, keep the same route choice and place the line more carefully. This controlled correction makes score changes easier to interpret.

Finish by transferring the skill into checking official fees before payment. Do not require a perfect score before progressing; require that you can identify what you did, why it was correct or incorrect, and what you would check on an unfamiliar map. That is a stronger preparation habit than simply accumulating completed route numbers.
