Hi graham and welcome to the forum
I think that you need to discuss your circumstances with your employer and come clean about your situation to avoid embarrassment. The credit check will identify the fact that your are in an IVA, but if your company are going to be the ones responsible for paying the account then you do not need to disclose this to your IP.
I feel that it is unlikely that you will pass a credit check with an ongoing IVA on your record, so do beware the sales talk.
