Section 75 for a UK locksmith overcharge — the exact claim, and the letter that starts it
Which route applies to you?
Section 75 applies if the item cost was over £100 and up to £30,000. Your card provider is jointly liable with the trader.
Chargeback under the Visa / Mastercard scheme rules. Not statutory, but widely honoured. Usually a 120-day window.
No card-provider route. Recovery is via the trader direct, Trading Standards (via Citizens Advice on 0808 223 1133), and the small-claims court for larger amounts.
The four conditions that unlock Section 75
- 1The card must be a credit cardSection 75 applies to credit cards, store cards and certain credit agreements. Debit cards fall under chargeback (see above), not Section 75.
- 2The item price must be more than £100 and no more than £30,000The threshold applies to the cash price of the service — not to the amount you actually put on the card. A £50 credit-card deposit on a £450 job still qualifies the whole £450.
- 3There must be a breach of contract or misrepresentationBeing charged materially more than the agreed or reasonable price is the classic breach. Section 51 of the Consumer Rights Act 2015 says only a reasonable price is payable where none was fixed — that is the underlying rule the card provider will apply.
- 4You must have paid the trader directly on that card (not via a third-party wallet)Payments routed through PayPal, Klarna or another intermediary usually break the direct-payment link Section 75 needs. If in doubt, the card statement's merchant name is the test — it should show the trader, not the intermediary.
Build your Section 75 / chargeback claim letter

Your letter
What happens after you send the letter
- 1
The card provider acknowledges the claim, usually within 5 working days, and opens an investigation.
- 2
They may ask you for further evidence: the invoice, the card statement, any written price agreed before work started, and photographs of the work performed and any damage caused. Send whatever they ask for promptly.
- 3
The investigation window is typically up to 8 weeks under the FCA's complaint-handling rules. Most Section 75 claims are decided sooner.
- 4
If the claim is upheld: the disputed amount is credited back to your card. The card provider then pursues the trader for recovery — that is their problem, not yours.
- 5
If the claim is refused: they must provide a written reason and confirm you may escalate to the Financial Ombudsman Service. The FOS is free to consumers and its decisions are binding on the card provider.

Before the next job, the timing rule that keeps Section 75 intact: pay a UK locksmith before or after the work — paying the balance on completion by credit card puts the full amount inside the Section 75 umbrella.
