I bought something small — does that count as a genuine customer?

The defense is about the purpose of the car park, not the value of your purchase. If the car park exists for customers of the premises, any genuine purchase during your visit supports the defense. There is no minimum spend requirement in the case law or the Code.

I was at the car park for longer than the permitted time as a customer — does this defense still apply?

This is more nuanced. If you significantly overstayed (e.g., 3 hours over a 2-hour limit), the Beavis proportionality argument is weaker. However, if the time overstayed was modest and you spent the whole time as a genuine customer, the defense still has merit — combine it with the grace period ground if the overstay was 10 minutes or less.

What if I was visiting a business in the building but didn't buy anything?

A business appointment (medical, legal, financial) may still support the genuine customer defense — the test is whether you were a genuine user of the premises the car park is designed to serve. An email confirmation of an appointment is useful evidence.

Does this work against IPC operators?

This defense is most clearly established under the BPA Code. IPC-regulated operators are subject to their own Code, which has similar provisions about legitimate interest. The Beavis principle is general case law and applies regardless of trade body, but POPLA (BPA appeals) is where most decisions on genuine customer grounds appear.

Summary

ParkingEye v Beavis [2015] UKSC 67 established that private parking charges are only proportionate if they serve the legitimate interest of managing parking for customers of the premises. Penalising an actual customer undermines that purpose. POPLA assessors apply this principle: a genuine customer with a receipt or bank statement showing a purchase during the parking period has approximately a 60% success rate. This defense applies to BPA-regulated operators only (not IPC or councils).

Legal Basis
ParkingEye v Beavis [2015] UKSC 67 (Lords Neuberger and Sumption, paras 94–99): 'Both ParkingEye and the landowners had a legitimate interest in charging overstaying motorists, which extended beyond the recovery of any loss. The interest of the landowners was the provision and efficient management of customer parking for the retail outlets.' BPA Code of Practice: signage must distinguish between customer and non-customer parking.

When This Defense Applies

This defense applies to BPA-regulated operators at retail, supermarket, or commercial sites where the car park exists to serve customers of those premises. The defense is that you were, in fact, a genuine customer of a business at the location during the parking period — and that penalising you contradicts the very purpose the parking restrictions are designed to serve. It does not apply to pure residential car parks, where no commercial premises relationship exists.

Evidence Required

One or more of the following strengthens the appeal:

Receipt from a store or business at the location, dated and timestamped during the parking period
Bank or credit card statement showing a transaction at the premises during the parking period
Evidence of an appointment at the premises (confirmation email, booking receipt)
Photo of signage distinguishing customer from non-customer areas, if relevant

Win Rate

Approximately 60% success at POPLA for genuine customer appeals against BPA members, particularly ParkingEye-managed sites. Higher success rates when combined with inadequate signage grounds.

Operator-Specific Patterns

ParkingEye: Manages many UK retail and supermarket sites. Genuine customer defense is strong at POPLA for ParkingEye cases, particularly where a receipt is produced. Euro Car Parks: Similar retail site pattern. Check whether signage on the site clearly distinguishes customer parking time limits from general public limits — if it does not, this is a signage compliance failure too.
