Share with negative net assets, 2014 to 2025
Share of accounts with net liabilities (total liabilities larger than total assets) by financial year end, for companies on the live register. Dissolved companies are not included because the register no longer lists their industry, so earlier years show survivors. Negative net assets is a warning sign, not proof of insolvency: see what negative net assets means.

Methodology
Industry is the first SIC code each company declares on the Companies House register (snapshot 1 October 2026); the dormant placeholder 99999 is excluded. Status, accounts type and due dates come from the register. Financial measures come from our parse of 37 million iXBRL accounts filed since 2008; values above £100bn are treated as extraction errors. Companies filing paper or PDF accounts are not in the balance sheet figures. Full details: methodology.
