BPA Code of Practice: the signage rules operators must follow

From the AppealAirportPCN team • LAST UPDATED: OCTOBER 2026

Many private parking companies belong to the British Parking Association (BPA). Members must follow its Code of Practice. Its rules about signs can be relevant when you challenge an airport PCN.

Signage is usually one point to raise alongside others. Our appeal templates include it where it may apply.

What the Code asks for

Paragraph 18 covers signs. In general, signs should be:

  • Prominent: easy to see and not hidden.
  • Legible: readable in the conditions where drivers approach.
  • At the entrance: displayed before drivers enter or commit to the area.
  • Clear about the price: the charge and main terms should be easy to find.
  • Frequent enough: placed around the site where drivers need the information.

A parking charge is usually claimed under a contract. If important terms were not clearly shown before a driver entered, that may support an argument that the terms were not agreed.

What to look for at an airport

Signs appear after the route commits you

At Stansted and Luton, check whether you could see the charge and choose another route before entering the zone.

Signs are hard to read

Small print, low contrast, poor lighting or signs placed too high or too far away can make terms difficult to read. Note what you could see from the driver's position.

The price is not clear

Check whether the amount is easy to find on the entry sign. A price hidden in small print or only available through a QR code may be difficult for a driver to see before entering.

Using this in your appeal: Explain which signs were missing, unclear or too late for you to make a choice. If possible, include your own photos or describe where the signs were. The operator may provide its own evidence in response.

Why signage can matter

If key terms were not clearly brought to the driver's attention, that may affect whether a contract was formed or what terms it included. Raise this point alongside other relevant grounds, such as the POFA relevant-land rule or late-notified charges.
