Hi Hazel, welcome to the communities. I don't have specific experience of your sector and perhaps you've already looked at this for general guidance but as a precaution if you haven't - this is the guidance from GOV.UK: www.gov.uk/.../right-to-work-checks-employer-guidance

Recommendations are fine... but please no self-promotion / advertising (I've had to remove one).

I used to work for an IT consultancy, we used HireRight then Onfido for these checks.

In reply to Lorraine:

Hi Hazel
ID / right to work in UK are really prerequisites, and then very much dictated by role, eg if there's likely to be unsupervised contact with under 18s / vulnerable adults or it's otherewise necessary, DBS checking, and of course employment history.

No need IMHO to pay for third party checking agents usually, although that said I've used specialist agents (usually retired senior police detectives etc) on a few occasions where we needed to be sure and / or send a message to the person involved that all possible stones would be uplifted and closely examined underneath.

It's really horses for courses and following up on anything that doesn't quite ring true and can't really see that it's useful to be any more prescriptive than just that.
