The Department said that the increased complexity of its accounts when compared to those of DIT was driven by balances moving across from BEIS.64 These balances had to be accounted for to a much higher level of precision due to the accounting concept of ‘materiality’. The materiality level set in BEIS for the audit of the Core Department was £575 million.65 The new department’s gross expenditure is significantly lower than that spent by BEIS and accordingly, the materiality level for the 2023–24 accounts of the Department was £43.5 million.66 This meant that some 59 HM Treasury, DAO 06/23 - Accounts Directions 2023–24, December 2023 60 DBT ARA 2023–24 61 Q 35 62 HM Treasury, Government Financial Reporting Manual: 2023–24, December 2023, p 84 63 Q 35 64 Q 35 65 BEIS, Annual report and accounts 2022 to 2023, p 179 66 DBT ARA 2023–24, p 123 19 balances which were previously immaterial in BEIS became highly material to the new department, necessitating increased work by the Department’s finance team.
