Step 1
You have to apply for a new check (unless you’ve just done so: see Step 2)
Step 2
Send your fully-completed application form and identity documents, off for countersigning. Our countersigners will send on your form to the DBS, returning your ID to you at the same time: you should then straight away register with the DBS Update Service using the application reference number on your application form, entering a few personal details and paying the yearly sub (£13 at August 2014).

Step 2
When you get your certificate, subscribe as above but using the certificate number. You have to do this within 30 days of the date the certificate was issued - so that doesn’t allow much leeway for delays in the post, you being away, etc.
Step 3
You add the details of your new certificate to your account. The DBS will then search regularly to see if any new information has come to light since it was issued, and the certificate details will be updated if there is new info (Reasons 2 or 3) on you
Step 4
You show your certificate to a prospective employer, and (unless there are problems, see below) they use the details on it to check online whether there has been new info on you since it was issued
Step 5
If you get a new certificate (eg because you need one for a different workforce (Reason 3) or to show updated info on you) you can add the details as in Step 3. You can have more than one certificate listed.
Step 6
You can keep an eye on who’s checking your certificate. If you don’t want them to do so, tell them you’ve revoked your permission - it would then be illegal for them to carry on checking (but you can’t actually block them from doing so).
