Frequently Asked Questions

What should a mechanic include on an invoice?

Include the vehicle registration, make, model, and mileage. Separate parts and labour clearly, listing part numbers where possible. State warranty terms for both parts and workmanship, and describe the work completed in plain language.

Do garages have to provide an itemised invoice?

While there is no strict legal requirement, the Consumer Rights Act 2015 entitles customers to clear pricing. Providing an itemised breakdown of parts, labour, and VAT builds trust and reduces disputes. It is considered best practice.

How should VAT be shown on a garage invoice?

If VAT registered, show the net amount, VAT amount, and gross total separately. Some parts may be zero-rated. Your VAT number must appear on the invoice. If not VAT registered, state that VAT is not applicable.

Should I include vehicle details on the invoice?

Yes, always include the vehicle registration number, make, model, and mileage at the time of service. This creates a proper service history and protects both you and the customer in case of disputes or warranty claims.
