Who says you need a new one? Maybe a different kind is needed- eg a fuller check. The DBS update service is worth having- saves having several DBS certs as others can view it online
Yes, you will have to pay an annual fee of £13 but it's cheaper than taking out new checks every 18 months. I don't understand though why we can claim income tax back on it as to me it's an essential cost of employment- no different to a uniform or subscription to professional body, for example
Applied at 2.35pm yesterday and got notification the certificate was in the post at 2.05pm this afternoon. 23 hrs 30minutes. Is that a record I wonder?
