An extended vehicle warranty is a way for you to pass the risk of your vehicle suddenly or unexpectedly suffering a mechanical or electrical failure to a covered component on to someone else.

An extended vehicle warranty has traditionally been a product that was sold or given away by the motor dealer at the same time as the used vehicle was purchased. Typically manufacturer warranties cover the vehicle for the first three years of its life.  After this cover expires, you are on your own.

This is where we step in and take care of all the stress and hassle for you. Our Best4 Warranty policies are designed with you in mind. You will find no other extended vehicle warranty brand that displays and lives by the principles of honesty, fairness and helping those most affected by the unexpected. These values extend to the very core of our business and it is these values that will define our relationship with you.

Your policy booklet will explain what is and what is not covered by the warranty you have taken out. If you cannot find your policy booklet either download the booklet PDF from this website or call us on +44 (0)3300 944 444 and request a handbook to be sent to you.

If the vehicle shows signs of an imminent failure, do not continue to use it. Providing that this is not the case please take your vehicle to any VAT registered garage and authorise them on your behalf to carry out diagnostics of the fault. When the garage has fully diagnosed the fault with your vehicle, but before they carry out any repairs, they must call us on +44 (0)3300 944 444 and advise us of what the fault is and what the cost of the repair is likely to be.

Please refer to your Best4 policy schedule to find your claim limit and hourly labour rate cap as this may influence your choice of garage. If your claim is successful you will still be liable for any costs that exceed the claims limit or hourly labour rate.

If you don’t have your policy schedule with you please call best4 on +44 (0)3300 944 444 and have your vehicle registration number.

No. It is essential that the claim has been approved by Best4 before any repairs have been carried out. However, we will, of course, consider emergency repairs if needed.

For you to be reimbursed you need to send Best4 the following paperwork within 30 days of the claim being approved:

  • Signed claim form (that the garage should give you to sign)
  • Correctly detailed VAT invoice made out to Best4
  • Proof of payment (that you made to the garage)

The exception to this requirement is if a Halfords Autocentre has repaired your car. In this situation, you don’t need to send Best4 warranty any documentation.

Please note: If you have fixed-term contract (e.g. a 12 month policy) and are paying monthly instalments then any remaining premium due will need to be settled before a claim can be finalised.

Once Best4 has received all the fully completed claim-related paperwork, we will transfer payment to your designated bank account within 14 days.
