Service and support FAQ /

Our customers generally find that the most convenient method to return a product for repair is to take it back to the retailer from where it was originally purchased. You can also directly send a repair to us by completing the online repair request form through your My Sigma account.

1. Login and complete the online repair request form.

2. Print copy of confirmation email with the supplied RMA number and include it in your returns package.

3. Include a copy of your sales receipt/proof of purchase if the item is within warranty.

4. Ship your item to us to the address below using an insured and tracked delivery service or via an authorised SIGMA UK reseller who can send it on your behalf.

We also offer a repair collection service for £28 (UK mainland only). Collections are handled by DPD and insured up to £5000.
To use this service, please call us on 01707 329999 (option 2) or email after completing the online repair request form.

Our postal address is:

Service Department

If the product is still within its 1-year manufacturer warranty (or 3-year extended UK warranty) the repair will be free of charge. If the product is outside of the warranty period, or the fault is not covered by the warranty, we will raise an estimate upon inspection.  A repair will not be carried out until we receive confirmation that you are happy to proceed.

Our service tariff can be used to find out what lenses can be repaired and as a general guide to standard costs. All repairs have a six month guarantee on work carried out.

All standard charges include parts, labour, return postage and VAT. Prices listed are intended only as a guide and charges may be revised on further examination. If you refuse the estimate, we will return your product un-repaired, which will incur a £14.99 charge that covers administration fees and return postage costs.

There is no need to contact us directly before returning a product, however the online repair form must be completed and a return confirmation email must have been received before being sent.
