Questions to ask before a garage fits parts you’ve bought

Last updated 19 October 2026

Buying parts yourself can save money, but it changes who is responsible for what. Ask these questions before you order.

1. Will you fit parts I’ve bought?

Many garages do, some charge differently, and some only fit parts they supply. It’s better to find out before you buy.

2. What exactly will you charge?

Ask for a labour-only quote in writing. Is it a fixed price or an estimate? Are there extras, such as fixings, fluids or disposal of the old parts?

3. What does your warranty cover?

A garage’s warranty often covers its workmanship but not the part itself. If the part fails, the claim may go to the retailer. Ask how it works and get the answer in writing.

4. Can you check the part before I order it?

Give the garage your registration and the part number or listing, and ask them to confirm it’s correct. Catching a wrong part before it’s bought is much easier than after.

5. Can the parts be delivered to you?

If you want the parts sent straight to the garage, ask about the address, opening hours, who signs for the delivery, how long they’ll hold the parts, and whether they’ll handle any returns.

6. What if the part turns out to be wrong?

Ask about the retailer’s return window, and whether the garage charges for wasted time or a missed appointment if the part is wrong.

7. Keep your records

Save the receipt, part numbers, the quote and the invoice. Photos of the packaging can help if there’s a dispute.

8. Leave time

Order early enough for the parts to arrive before the appointment, with a day or two spare.

In the UK, services must generally be carried out with reasonable care and skill, and goods bought from a retailer should be of satisfactory quality and as described under the Consumer Rights Act 2015. Terms with individual garages and retailers vary, so ask before you buy. This isn’t legal advice.
