Car warranties provide peace of mind by covering the cost of unexpected repairs.
But when it comes to servicing, many drivers worry about whether using the wrong garage could void their warranty.
The good news is that their are consumer protection rules in place that mean you are not tied to the dealership. However, there are also some important conditions to be aware of to make sure you don't fall foul of your warranty agreement.
What is a car warranty?
A car warranty is a protection plan that covers the cost of repairs for mechanical or electrical faults within a set period, usually two to seven years for new cars.
The main types of warranty are:
- Manufacturer warranty – included with new cars, often the most comprehensive.
- Extended warranty – offered by dealers or manufacturers after the original warranty expires.
- Aftermarket warranty – insurance-style policies sold by third parties, which may have stricter terms.
Do I have to service my car at the dealership?
No. Under UK and European “Block Exemption” rules, a manufacturer cannot force you to use its dealer network to keep your warranty valid.
You are free to use an
independent garage, provided that:
- The service follows the manufacturer’s schedule and intervals.
- The correct, approved parts, fluids, and oils are used.
- Full records are kept, including a stamped service book and itemised invoices.
Failing to follow these requirements could invalidate your warranty, so documentation is essential.

How different warranties affect servicing
| Warranty Type
| Can You Use Any Garage?
| Key Notes
|
|---|
| Manufacturer warranty
| Yes, if schedule and parts are correct
| Keep full records
|
| Dealer extended warranty
| Often No
| Many restrict servicing to the dealer network
|
| Aftermarket warranty
| Sometimes
| Terms vary, check carefully
|
| PCP / Lease agreement
| Depends
| Finance companies may require franchised servicing
|
It is worth noting that even when independent servicing is allowed under a warranty, finance or lease agreements may still require main dealer servicing to maintain a car’s guaranteed future value.
Is servicing covered by a car warranty?
No. Warranties cover repairs to faults, not routine maintenance.
You are responsible for paying for
servicing, oil changes, brake pads, tyres, and other wear-and-tear items.
However, neglecting to service your car correctly can void warranty claims.
For example, if your engine fails because servicing was missed, the manufacturer may reject the claim.
Servicing vs MOT - What’s The Difference?
An
MOT is a legal road safety and emissions test, whereas servicing is routine maintenance to keep the vehicle running smoothly.
A warranty will not cover MOT costs, but may cover repairs for faults identified during servicing if they fall under the warranty terms.

Car Warranty & Servicing FAQs
Can a car under warranty be serviced anywhere?
Yes, provided the garage follows the manufacturer’s schedule and uses approved parts and fluids.
Is my car warranty void if not serviced?
Yes. Failing to service your car on time or using incorrect parts or fluids can void your warranty.
What are two reasons not to buy an extended warranty?
1. The cost may outweigh the likelihood of needing major repairs.
2. Many extended warranties exclude wear-and-tear and may restrict servicing to certain garages.
Are services covered under warranty?
No. Servicing is a routine cost and is not included in warranty coverage.
Does getting an oil change somewhere else void the warranty?

What happens if a car cannot be repaired under warranty?
You may be entitled to a replacement, refund, or compensation under the Consumer Rights Act if the car is beyond repair.
