- Absent is not zero. A figure shown as Not reported was not given in the accounts we hold. Small and micro companies do not have to file a profit and loss account, so turnover and profit are usually absent for them.
- Accounts for years ending in 2025 and 2026 are still being filed, so the newest years may be missing.
- * This filing does not give total assets less current liabilities, so the figure shown is fixed assets.
- Employees, cash and net assets are shown as Not shown when the filed figure is not possible (for example a negative headcount or negative cash).
Definitions
- Total assets less current liabilities
- Fixed assets plus current assets, minus what the company owes within a year. It is not total assets: cash can be larger than this figure when the company owes a lot in the short term. Where a filing does not give it, the table marks the fixed-assets figure used instead.
- Net assets
- What the company owns minus everything it owes. Also called shareholders' funds.
- Turnover
- Sales for the year. Only larger companies report it.
- Accounts
- The accounting framework named in the filing (for example FRS 102). Not stated means the filing does not say.
