UK VAT investigation help

[Bry]

Hello,

I have just been assigned a client in my new workplace and was just hoping for a few tips on how fellow accountants would go about things.

The client's bookkeeper did not realise the company was exceeding the VAT threshold. It is now my job to ascertain when VAT should of been registered for and how much VAT is now due.

Any tips on how i go about this and what order i should do things in?

Also does anybody know of any tax relief on catering for government and professional associations? Just heard somewhere it may be zero rated or exempt.

Would greatly appreciate some advice.

Thanks
