Do you claim VAT on B&Q receipts?

No VAT number or VAT breakdown on the receipts however there is a reasonable amount of business expenditure for repairs done on the business premises and there would be about €300 in VAT.

Is it possible to bring back the receipts to B&Q and ask for an invoice?

there is a vat amount and BandQs vat no an the reciepts. I always claim the vat on their reciepts

Just saw the VAT number on the back of the receipt, no breakdown though.
