Mr Frank Field: Asked the Secretary of State for the Home Department :

1. how much money was received by the Criminal Records Bureau in income from fees from each type of registered body and umbrella group in 2009-10;
2. how many Criminal Records Bureau disclosures were issued for each type of registered body and umbrella group in 2009-10.

Lynne Featherstone: In 2009-10 the Criminal Records Bureau (CRB) received a total income of £123 million from fees.  Information relating to fees is held on a separate system from that which provides the figures for the number of certificates issued therefore the Bureau is unable to provide a breakdown in the format requested.

During this period the Bureau issued 4,294,977 certificates to Registered Bodies. Of these, 2,495,017 were issued to organisations that are known to operate an Umbrella Body service. I should also note that 933,271 applications were for voluntary positions which the Bureau issues free of charge.

I should explain that there is no legal definition of an Umbrella Body. These are Registered Bodies that are willing to submit applications on behalf of other organisations that are not eligible to submit CRB checks themselves.
