National's Warranty Policy

National Autoparts' policy is to maintain a high standard of quality in all aspects and to continually satisfy customers in respect of products and services.

Our warranty policies are an important aspect of our overall service offer. They cover parts which have failed in service or fitment to defects in materials or workmanship, for passenger cars and light commercial vehicles.


National's Brake Warranty Policy

All of our brake products are guaranteed for 2 years or 20,000 miles (32,000 km) whichever is sooner.

Occasionally, we receive a warranty clutch where cause for the return is clearly beyond the control of the clutch. These types of claims are excluded from our warranty policies - see below.


Warranty Clutch Exclusions

We reserve the right to reject claims where damage has occurred through incorrect fitment, handling, misuse, abuse, contamination by oil or grease, vehicle modification from original specification and any form of racing  activity which can be considered outside of normal road use.

To assist your returns department with a diagnosis, we have provided images of excluded claim types below.

If a returned warranty is deemed to be void due to an avoidable external factor which has resulted in the perfectly good clutch being returned under warranty, or one that has been damaged by external factors beyond the control of the clutch – then we will provide detailed feedback of our findings to our customers.

The feedback will consist of an examination report, test machine printed reports, technical service bulletins and detailed photos whenever relevant.

It is our sincere hope, in providing these examination reports, that our customers will learn what has been done incorrectly when the returned warranty is examined and awareness of any unacceptable fitting practices or vehicle faults are commonly identified at an early stage. This will break the cycle of repetitive clutch replacements when the underlying cause of the complaint lies elsewhere.


Warranty Carriage Charges

From 4th January 2016, all rejected warranty claims will be kept at National Auto Parts for a maximum of 30 days after the rejection date.

A member of National's staff will contact the claimant, as soon as is reasonably possible, to advise of the reason for the rejection and to enquire if the claimed parts are to be returned or disposed of.

Should the customer wish to arrange collection of the goods, please contact our customer service team. A charge will be made for the return of rejected parts at the current rate which could be subject to change without prior notification.

Rejected claims returned along with normal stock order items will not be charged for – the customer must request this at the time of notification of the claim being rejected.

Your statutory rights remain unaffected by the above.


Stock Cleanse

All stock cleanses MUST be agreed with a member of National’s Sales & Marketing team prior to return.

Any unplanned cleanses are likely to be refused delivery. Therefore, all cleanses should be mutually agreed in advance.
