See http://www.disclosure.gov.uk/ for full info. Cost is £29 for standard and £34 for enhanced (you need enhanced if you're going to be working unsupervised with vulnerable people) but if you're applying because of a job that needs a disclosure the employer may pay that fee.
And yes the service is part of the Criminal Records Bureau (CRB), they do a background check on you.
Also make sure you know if you want an enhanced or standard when you phone them. Also they will want your job title and employees address. Plus you need to take identification to your employer for varification.
by vulnerable people i always thought it was for children cases etc. i only thought that because my mum has the second CRB clearance because she works with the poilce, and had to work on something with the child protection unit. i also thought there was another level after that, i cant remember what it was for though.
