We recently deregistered for VAT and I have followed all of the actions on the Sage advice in relation to VAT deregistration.

However, on Company Preferences although I have deleted the VAT reg number the instructions do not say whether I need to change the VAT scheme selection. 
This is currently set to Standard VAT, there are 4 options -

Standard VAT
VAT Cash Accounting (UK)
Flat Rate - Invoice Based
Flat Rate - Cash Based

But no option to remove this completely. The instructions on Sage - De-register for VAT - UK only - does not mention having to do anything with this, just deleting the VAT number once all the other actions have been completed. So do I just leave it as we have deregistered part way through a financial year?

Thanks in advance for any help and advice people can offer.
