What Is the BPA and IPC Code of Practice? A Guide for UK Motorists

If you have received a private parking charge in the UK, two acronyms come up repeatedly: BPA and IPC. Both organisations publish a code of practice that their member parking operators must follow. Understanding what these codes say, and when an operator has broken them, is often the key to a successful appeal.

The Two Trade Associations

Private parking in the UK is self-regulated through two rival trade bodies:

Organisation	Full name	Appeals service
BPA	British Parking Association	POPLA (Parking on Private Land Appeals)
IPC	International Parking Community	IAS (Independent Appeals Service)

Every private parking operator that wants to use keeper liability under the Protection of Freedoms Act 2012 (PoFA 2012) must belong to one of these two bodies and comply with its code of practice. PoFA 2012 is the law that allows operators to pursue the registered keeper of a vehicle, not just the driver, so membership matters enormously to them.

Important distinction: The BPA and IPC codes apply only to private parking charges issued by companies on private land. They have nothing to do with Penalty Charge Notices (PCNs) issued by councils or Transport for London, which are governed by separate statutory rules and appealed through the Traffic Penalty Tribunal or London Tribunals.

What Does a Code of Practice Actually Cover?

Both codes set minimum standards for how operators must behave. The rules overlap significantly, though the precise wording differs. Key areas include:

Signage

Operators must display clear, legible signs at the entrance to a site and throughout it. Signs must state the parking conditions, the charge that will apply for a breach, and contact details. If signage is inadequate, the operator cannot lawfully claim a contract was formed with the driver.

Grace Periods

Both codes require operators to allow a minimum grace period before issuing a charge. The standard is currently 10 minutes after the permitted parking time expires. There is also a consideration period, a few minutes, for a driver who arrives, reads the signs, and decides to leave without parking. If a charge was issued within these windows, it is likely to be cancelled on appeal.

Charge Amounts

Codes cap the maximum charge an operator can issue. As of 2024, the BPA cap for most sites outside London is £100, rising to £110 in London. IPC caps are broadly similar. A charge higher than the permitted cap is unenforceable.

Notice to Keeper (NtK)

Under PoFA 2012, an operator must send a compliant Notice to Keeper within 14 days of the parking event if they want to hold the keeper liable. The BPA and IPC codes specify exactly what information that notice must contain. A defective or late NtK breaks the keeper liability chain, meaning only the driver (if known) can be pursued.

Appeals Process

Both codes require operators to run an internal appeals process and, if the appeal fails, to offer an independent appeal, POPLA (BPA) or IAS (IPC), at no cost to the motorist. The operator cannot chase payment while an appeal is live.

Why Does This Matter When You Are Appealing?

When you write an informal or formal appeal, your strongest arguments are often that the operator broke its own code of practice. Common breaches to look for:

• Poor or missing signage, no sign at the entrance, signs obscured, or terms too small to read from a car
• Charge issued within the grace period, check the exact time stamps on any ANPR images
• Late or defective Notice to Keeper, check the date it was sent against the date of the alleged contravention
• Charge above the permitted cap
• No compliant landowner authority, the operator must have a contract with the landowner; some codes require evidence of this

Quoting the specific section of the relevant code that has been breached makes your appeal considerably more persuasive.

How to Find the Codes

Both codes are publicly available:

• BPA Code of Practice: britishparking.co.uk, look under "Accredited Operators Scheme"
• IPC Code of Practice: theipc.uk, look under "Codes of Practice"

To find out which body your operator belongs to, check the parking charge notice itself, it must state whether the independent appeal route is POPLA or IAS.

A Balanced Note on Appeals

Not every code breach will automatically cancel a charge. POPLA and IAS assessors weigh the evidence and use their own judgement. A minor procedural imperfection may not be enough on its own; a combination of issues, or one serious breach such as a late NtK, usually is. If your situation is straightforward, the paperwork is clean, and you genuinely did breach the parking conditions, it may be more practical to pay the reduced early-payment amount than to spend time appealing.

That said, if you have spotted a genuine breach of the BPA or IPC code, it is almost always worth challenging. The codes exist precisely to protect motorists, and operators are well aware that assessors take breaches seriously.
