HM Treasury publishes the total level of public sector liabilities for previous financial years in the Whole of Government Accounts (WGA). This sets out the total level of central and local government liabilities, which includes any debt owed by their arm’s length bodies (ALBs).
HM Treasury does not however hold information on the specific levels of debt attributable to each ALB.
This information can be found in the individual accounts of each body, and is aggregated in the accounts of the ALB’s parent department. WGA contains a list of all such bodies consolidated into the account.
Where ALB's are permitted to borrow, they must do so in accordance with the restrictions and controls set out by HM Treasury in Consolidated Budgeting Guidance and Managing Public Money.
