Frequently Asked Questions
List each part separately with its description, quantity, and cost so customers see exactly what you've replaced. Clearly distinguish parts costs from labour charges, and include the component name and any relevant specifications (e.g. "Bosch front brake pads, 205/55R16"). This transparency prevents disputes and provides clear documentation for warranty claims. You can mark up parts based on your business model; customers accept this if clearly itemized. Include quantity only when multiple identical items are replaced, such as paired brake pads or wheels.
Show labour as a separate line item with an hourly rate or flat rate depending on the work. For complex jobs, break down labour by task (e.g. "Diagnostic scan: 0.5 hrs," "Brake pad replacement: 1.5 hrs") so customers understand the time investment required. Document actual hours worked or agreed-upon estimates to support your invoice if questioned. UK garages typically charge £40–£120 per hour depending on specialization and location. Itemized labour rates reduce disputes and position you as a transparent, professional operation.
Yes—diagnostic work is a distinct service and should be invoiced separately, even if the customer declines repairs. Charge a flat rate (typically £30–£80) or hourly rate for diagnostic time, depending on complexity. Make clear whether this fee is refundable if the customer books repairs with you, or whether you'll credit it against larger repair costs. State this policy on the invoice to avoid confusion. Separate invoicing for diagnostics protects you and sets clear expectations about what customers are paying for before repairs begin.
Most repair services, labour, and parts attract the standard 20% VAT in the UK. However, MOT testing fees are exempt from VAT—invoice these separately without VAT added. If you're below the VAT registration threshold (currently £85,000 annual turnover), you don't have to register, but you can choose to. If registered, you must charge VAT on invoices and declare it quarterly to HMRC. Always show VAT as a separate line item so customers understand the total cost breakdown.
Keep all invoices and service records for at least six years for tax purposes, as required by HMRC. This includes labour timesheets, parts documentation, and customer correspondence related to each job. Detailed records also protect you if a customer makes warranty or quality claims months later—your invoice proves what work was carried out and when. Digital backup is wise; scan or photograph invoices if you issue paper copies. Six years covers the statute of limitations for most disputes and ensures you can evidence income if audited.
Issue a new invoice for any follow-up work, even if it's related to a previous repair. Reference the original invoice number and date so you and the customer can easily connect the jobs. Clearly state whether it's under warranty (no charge), a warranty extension, or a separate service. If the original invoice included a warranty period, state the coverage terms so customers know what's protected. For repeat visits on the same fault, document the first attempt, diagnosis, and subsequent repair on separate invoices with clear dates for a complete service history.
Most UK garages request payment in full at the time of service or within 7–14 days for account holders. State payment terms clearly on the invoice (e.g. "Payment due within 7 days" or "Payment required before collection"). Specify accepted payment methods: cash, card, bank transfer, or cheque. For regular business customers, you might offer 30-day terms, but document this in a separate credit agreement. Late payment penalties under the Late Payment of Commercial Debts (Interest) Act 1998 can be added after the agreed date, but these must be stated upfront.
Address disputes promptly and professionally by reviewing your documentation: labour hours, parts used, and any quotes or authorizations provided before work started. If you gave a price estimate, honour it unless you discovered additional faults during diagnosis—in which case you should have communicated this before proceeding. Offer to explain line items in detail and show the parts or evidence of work. If you can't resolve it, refer to your terms and conditions for your dispute resolution process. Detailed, transparent invoices prevent most disputes by itemizing all work clearly from the start.
