Consumer Rights in Peer-to-Peer Transactions Explained | LegalDocuments.co.uk

Overview

A peer-to-peer transaction, in plain terms, is a sale or exchange between two private individuals rather than between a consumer and a business. The distinction matters a great deal legally. When you buy from a trader, the Consumer Rights Act 2015 gives you robust rights around satisfactory quality, fitness for purpose and matching the description.

When you buy from another private person, those statutory consumer protections largely fall away, and you are left relying on general contract law and a narrower set of rules. Platforms such as eBay and Facebook Marketplace add their own layer on top, buyer protection schemes, dispute resolution processes and rules about listings, but those are contractual arrangements with the platform, not your legal rights.

Understanding which category your transaction falls into is the first question to ask when something goes wrong. Someone who sells the odd unwanted item is private. Someone who consistently lists for profit may legally be a trader even if they claim otherwise, and that changes everything.

Key steps

1. Work out whether the seller is private or a trader. The protections available to you depend entirely on this. Look at how often they list, whether they buy stock to resell, and how the listings are worded. Someone running a de facto business from a personal account may still owe you trader-level duties regardless of how they describe themselves.
2. Keep every piece of evidence from the listing and messages. Screenshot the original advert, save all chat history, keep payment confirmations, and photograph the item on arrival before unpacking fully. If a dispute follows, this contemporaneous record is usually the difference between a successful claim and a he-said-she-said stalemate that goes nowhere.
3. Raise the issue with the seller directly and in writing. Most disputes resolve faster when the first approach is civil, specific and documented. Explain what the problem is, reference the listing wording, and say clearly what you want, a refund, a partial refund, or return of the item. Give a reasonable deadline for a response before escalating.
4. Use the platform's dispute resolution before going legal. eBay's Money Back Guarantee, PayPal's buyer protection, and similar schemes on other sites often resolve issues quickly without anyone needing a lawyer. Facebook Marketplace offers less in-built protection, but Purchase Protection applies to some shipped items paid through checkout. Check the specific terms for your transaction.
5. Consider the small claims track if informal routes fail. For sums up to £10,000, the small claims procedure in the County Court is designed to be used without a solicitor. You will need to show a contract existed, that the other side breached it, and what your loss was. Mediation through the court's free service resolves many claims before a hearing.
