Refund & cancellation policy.

You may cancel any order for a full refund at any time before we begin building your calibration file, and before hardware has been activated or dispatched. Email support@norrismotorsports.co.uk with your order number and we will refund the full amount to your original payment method.

Every calibration is built individually from your own ECU file, for your specific vehicle, fuel and hardware. Because these are custom-made digital goods, the standard 14-day cooling-off period does not apply once work has started and the file has been delivered — you agree to this when you place your order.

• Before work starts: full refund.
• Work started but not yet delivered: partial refund reflecting the engineering time already spent.
• File delivered or downloaded: no refund, but we will keep revising the calibration until it runs correctly.
• If we cannot support your ECU after you have paid, you receive a full refund.
• If your file is never delivered, you receive a full refund.

If a delivered file does not behave as expected, contact us first. Stage 2 orders include post-flash datalog review, and we will revise your calibration free of charge until it is right for your vehicle. Most concerns are resolved by a revision rather than a refund.

Installation bookings can be cancelled for a full refund up to 48 hours before your appointment. Cancellations inside 48 hours, or missed appointments, may be subject to a charge from the partner garage.

• All refunds are issued in pounds sterling (GBP, £) to the original payment method.
• Approved refunds are submitted within 3 working days.
• Your bank or card issuer typically shows the money within 5–10 working days.
• We do not charge any administration fee on an approved refund.

Email support@norrismotorsports.co.uk with your order number and a description of the issue. We acknowledge every message within 24–48 hours and aim to resolve disputes directly with you before any card chargeback is needed.
