Criteria for inclusion: Companies must be incorporated in the UK as companies limited by shares, unquoted, independent and at least 25% owned by employees on a broad basis. Companies may have non-UK holding companies if the UK companies are operationally independent and the non-UK holding companies are at least 75% owned by employees. Shares from joint ventures and associate companies are excluded.
Criteria for exclusion: The list does not cover quoted companies, the performance of which is tracked by the UK Employee Ownership Index. In businesses constituted as industrial and provident societies and as community interest companies, employee ownership can be hard to ascertain from published sources so, in such cases, we have relied on a business's membership of EOA as evidence of employee ownership. The list excludes companies limited by guarantee and partnerships such as lawyers and accountants.
Data collection: Several sources were used, including internet searches, lists of EOA members, Companies House searches and professional advisers active in the sector. Figures for employee numbers and revenues are taken from companies’ latest published annual accounts at Companies House as at 22 May 2015. Estimates of the percentage of employee ownership in each company were sourced from the companies’ own websites or EOA or press reports, corroborated where possible from annual returns.
Disclaimer: Employee ownership data is not systematically published by companies so the list may not be accurate. Nominations for inclusion and corrections should be sent to email@example.com.
Definition of terms: Operating profit or EBITDA is defined as earnings before interest, tax, depreciation and amortization. Productivity is defined as value added per employee. Value added is defined as EBITDA plus total wages. Debt is defined as the sum of bank loans and overdrafts, other short term finances and other long term finances minus cash.
