Platform-to-Business Regulation: Fair Rules for UK Online Sellers

Into to Platform-to-Business Regulation

The Platform-to-Business Regulation (EU Regulation 2019/1150) is a law designed to protect small businesses and traders who sell through major online platforms (marketplaces, app stores, social media shops and the like). It takes effect in the UK just as it did in the EU. In plain English, it means platforms must play fair: they have to use clear contracts, give sellers advance notice of changes or suspensions, explain their decisions, and set up simple appeals. This levels the playing field against powerful “gatekeeper” platforms (think Amazon, eBay, Apple’s App Store, Google Play, etc.) that connect you to consumers.

How it works in the UK after Brexit

The UK adopted the P2B rules into law on 12 July 2020 and has retained them after Brexit. In practice, that means from 2020 on, online marketplace rules in the UK are governed by the same safeguards that applied in the EU. UK-based platforms (and foreign platforms serving UK businesses) must follow these rules. The UK “Enforcement Regulations 2020” make non‑compliance legally binding: sellers can go to court if a platform breaks the rules, and contract clauses that break the rules may be void.

In short, P2B is UK law now. It creates a framework where contract terms and dealings with platform sellers must be fair, clear and predictable. Although this regulation came from the EU, UK courts can enforce it, and affected businesses or trade associations can take action if needed.

Key protections for sellers

Under the P2B rules, platforms must follow specific requirements that protect you as a seller. In clear terms, your online “contract” with the platform must cover important points in plain language, and the platform can’t change the rules on a whim. For example:

• Transparent terms & changes: The platform’s Terms and Conditions must be easy to read and find (for example, on its website). Any change to fees or rules requires at least 15 days’ notice, and you must be given the right to leave if you don’t agree. In other words, they can’t slip in changes overnight without warning.
• Suspension/Termination rules: If the platform wants to suspend or ban your account or listings, it must tell you why. In particular, before termination (ending your contract entirely), you must get at least 30 days’ advance notice with clear reasons. If the suspension is temporary, they still have to give you a statement of reasons beforehand. You should never lose access without explanation.
• Ranking transparency: Platforms that rank or sort products (like search results or app charts) must explain the main factors that determine those rankings. If paying more money or accepting extra conditions can improve your rank, that has to be disclosed. You should know why one product appears above another in search or recommendation lists.
• Fair treatment / data access: If the platform sells its own goods or services, or promotes certain sellers’ products, it must disclose any “differentiated treatment”. For example, if the platform’s own product always wins in a category, that should be clearly stated. The platform must also explain how it uses any data about your sales or customer reviews. They must tell you if they share your data (like customer reviews or ratings) with third parties, and under what conditions.
• No hidden restrictions: The rules prohibit secret barriers on how you sell outside the platform. If the platform has policies that stop you from offering your goods cheaper or in other channels, they must explain the legal or commercial grounds for that restriction. For instance, if the platform forbids you from selling the same item at a better price on your own website, it must justify that rule in writing.

These points can be summarised from UK guidance and expert summaries. In practice, any clause in a platform’s contract that violates these rules cannot be enforced against you.

What platforms cannot do

Because of the P2B rules, platforms cannot take unfair shortcuts. For example, they cannot:

• Delist or deactivate your account without giving a reason. (They must issue a clear statement explaining the suspension or ban.)
• End your contract on a whim. (They must give at least 30 days’ written notice and valid grounds.)
• Change fees or other key terms overnight. (They need to notify you 15 days in advance of changes.)
• Bury important rules in legalese. (Terms must be in plain, intelligible language.)
• Hide how their search or ranking works. (They must share ranking criteria and any paid influence.)
• Secretly favour their own products. (They must explain any different treatment of their goods vs. yours.)
• Block you from selling better elsewhere without good reason. (They must explain restrictions on outside sales.)

In short, surprises and unfair treatment are forbidden. The law explicitly bans sudden, unexplained actions by the platform. If they fail to follow these obligations (for example, by changing terms with no notice or suspending you without objective reasons), those particular terms or actions are not binding.

Your rights and dispute resolution

If you feel a platform has treated you unfairly, you have rights and avenues to challenge it:

• Right to information and appeal: You can demand a written explanation if you’re suspended or closed out. As noted, a platform must give reasons and notice. You also have the right to terminate the contract if you don’t agree with late changes. Keep records of all communications.
• Internal complaints process: Most platforms are required to offer a free complaint-handling process for business users. (Only the very smallest platforms may be exempt.) This means you should find a way to formally complain to the platform – often via email or a support form – about the unfair practice. The platform’s contract should tell you how to do this.
• Mediation/ADR: If the platform’s response is unsatisfactory, the P2B rules say there must be a way to escalate. Large platforms must identify at least two independent mediators or ADR bodies that they would use to resolve disputes. You can then ask the platform to mediate via one of those organisations. The platform is supposed to engage in good faith mediation and cover at least half the cost. For example, CEDR offers a UK mediation service for platform disputes.
• Legal action: If mediation fails or isn’t suitable, you can pursue legal action. UK law now explicitly allows you (or a representative body) to take a non‑compliant platform to court or tribunal. Non-profit trade associations (like retail or seller groups) may also sue on behalf of sellers. In practice, this means you could claim breach of these P2B rules through civil proceedings.

Example scenario: Suppose you sell gadgets on a big online marketplace, and suddenly one of your listings disappears. Under P2B, the platform must immediately tell you that it is suspending that listing and why (e.g. alleged policy violation). If it instead simply shut you down with no notice, you could cite the regulation and ask for an explanation. If unsatisfied, you could file a complaint through the platform’s customer support, then request mediation. If the platform refuses to cooperate, you could involve a trade association or lawyer to enforce your rights.

Another example: A platform announces new fees effective in 5 days, and gives no way to opt out. P2B says you should have been given 15 days’ notice and the option to end your contract if you disagree. You could formally protest this change, citing the regulation’s notice requirement, and (if needed) threaten to terminate or seek mediation.

Resolving disputes

In summary, if you’re unfairly treated on a platform:

1. Use the platform’s internal complaint process. Clearly state the issue and cite the rule if possible (e.g. “The Platform-to-Business rules require you to give 30 days’ notice before termination”).
2. Request mediation. If unresolved, ask for the names of the mediators listed in the platform’s terms and initiate a mediation session.
3. Seek legal remedies. If needed, contact a solicitor or trade association to explore court action. The law supports your ability to sue for breaches of P2B rules. Keep in mind that consumer and competition watchdogs (like the CMA) may also take interest in systemic issues.

Each step should be in plain, documented form (emails, letters). By law, the platform cannot charge you to appeal or force you out unreasonably. Your rights under this regulation are tools to ensure fairness. Use them to negotiate or challenge any action that seems unjust.

In short: The Platform-to-Business Regulation gives UK sellers clear protections – transparent terms, fair notice, and avenues to complain. It stops platforms from springing surprises and helps ensure you have a voice if something goes wrong. Remember that this is backed by law – if a platform oversteps, the offending terms can be voided and you can fight back, up to taking legal action.
