I've charged vat on an invoice that should haave been zero rated?

It's great to see you around, @W Everitt,

You can manually correct the invoice to remove the VAT from that sale. Here's how:

1. Go to the Sales menu then tap the Invoices tab.
2. Locate the invoice to edit from the list.
3. Click the arrow below the Actions column.
4. Select the View/Edit option. (See sample screenshot.)
   

After the correction is made, the discrepancy will show as VAT exceptions in the current VAT return.

To learn more about VAT exceptions, see this article: VAT exceptions and reports.
