      Who is the SIA?

      The Security Industry Authority (SIA) is the organisation responsible for licensing individuals who work in certain parts of the UK’s private security industry.

      Common SIA licence questions

      • The SIA should have sent you a licence application reference number. Bring this to a participating branch within 3 months of completing your on-line Security Industry Authority licence application.

        Make sure you bring originals of any documents requested, not photocopies. We'll send your application electronically to the SIA.

        We will check your documents, take your photograph, record your signature and take payment (if applicable.)

        For an additional fee we'll post any supporting documentation off to the SIA for you.

      • Your Next Steps Notification from SIA will tell you if you need to send any documents directly to them.

        You need to send everything to the SIA within 21 days of visiting the Post Office or your application may be withdrawn.

        Until the SIA receive your documents they will not be able to progress your application further.

      • Yes; if you want the Post Office to post any extra documents to the SIA, you’ll be charged an additional fee to cover the cost of postage and envelope.

        You will also need a covering note with your reference number and your full name and address.

      • Once we’ve taken your photo and recorded your signature, we send them electronically to the SIA where they're added to your application.

        The SIA will then continue to process your application.
