None vat purchase items appearing in box 7 (screen shot)

when i download the calculations i noticed it adds up all the sales the first 4 are to sub contractors that aren’t vat registered and i have a cash sale vehicle

it makes my Total value of purchases exc VAT a lot more .

is this normal to have sub contractor in there and other nil value vat things ?

Yes any items with zero VAT would normally be included in the total for box 7, but this does not affect your final VAT calc. If you mark the invoice as exempt or out of scope then they will be completely excluded from the return, if that’s what you want.
