Technical Support

Please visit our Frequently Asked Questions page to find answers on many issues, If you can not find any answers there we have a technical support hotline. The technical support line number is 01728 727424. The line is manned during normal working hours, Monday to Friday. Alternatively you may e-mail us if you wish.
If your query relates to a recent purchase, please have available your Castle Technology Invoice number as this will be required before we can issue a returns number.

If you did not purchase the Castle Technology product directly from Castle Technology, any warranty is, in the first place, with your supplier. You will need to contact your suppler and get them to tell you the Castle Technology invoice number on which the goods were supplied to them. As long as the goods are still in warranty with Castle Technology (the date of the Castle Technology invoice provides the start date for this warranty) we will be happy to deal directly with you.
