Subject: Invoice Dispute - Invoice #[Invoice Number] Overcharge Request

Dear [Mechanic/Garage Manager's Name or "Customer Service Team"],

I am writing regarding Invoice #[Invoice Number] dated [Date] for repairs on my vehicle [Make/Model/Reg Number] at your [Garage Name/Location].

The total charged (£[Amount]) exceeds our agreed estimate of £[Agreed Amount] by £[Disputed Amount]. Specifically:

• [Brief evidence summary, e.g., "£500 for unneeded parts not authorized."]
• [Attach photos/receipts/prior quotes.]

Under the Consumer Rights Act 2015, services must be provided with reasonable care and skill, at a reasonable price, and within a reasonable time. This bill breaches these standards.

I request:

1. A revised invoice correcting the overcharge.
2. A full refund of £[Disputed Amount] within 14 days.
3. Confirmation by [Deadline, e.g., 14 days from today].

Please reply by [Date, e.g., 14 days from email date] to avoid escalation to Trading Standards.

Thank you for your prompt attention. I value your services and hope to resolve this amicably.

Best regards,
[Your Full Name]
[Your Phone Number]

Your Legal Rights Under Consumer Rights Act 2015 for Auto Repairs

UK law empowers you against dodgy garage bills. The Consumer Rights Act 2015 (supplemented by Supply of Goods and Services Act 1982) mandates:

• Reasonable Care and Skill: Repairs must meet professional standards--no shoddy work.
• Reasonable Price: Charges can't exceed fair market rates or quotes without agreement.
• Reasonable Time: Delays without reason breach rights.

Stats show strong protections: Citizens Advice resolves 70% of disputes citing the Act. Mini Case Study: A garage charged £500 extra for unneeded parts. Customer emailed citing the Act--full refund issued in 7 days (Contend Legal).

If breached, demand repeat service, price reduction, or refund. No need for court initially--email complaints often suffice.

When to Dispute an Auto Repair Bill: Common Issues and Red Flags

Not every bill is wrong, but these warrant action:
