In line with our commitment to be transparent about how much we spend and on what, we publish the details of our spending. We record the spending in the form of a register, listing individual items of expenditure and details such as the payee and the date of payment. The threshold which we include an item of expenditure on the register stands at £250 (excluding VAT) for each item of expenditure.
