I first reviewed Company Check (http://www.companycheck.co.uk/) earlier this year (Free UK company information http://www.rba.co.uk/wordpress/2011/01/10/free-uk-company-information/). Since then they have made more UK company information available free of charge. As well as Cash at Bank the service also shows 6 years of figures and graphs for Net Worth, Total Liabilities and Total Current Liabilities. Data is taken from official Companies House documents. Documents can be purchased through UK Data (http://ukdata.com/) but they are much more expensive than ordering direct from Companies House (http://www.companieshouse.gov.uk/) or bizzy (http://bizzy.co.uk/). UK Data’s detailed credit reports are worth considering though if you want more in depth analysis. Although Company Check lists the company directors it does not show other directorships as does bizzy. (See my previous posting Company information: Bizzy for UK company data and credit ratings http://www.rba.co.uk/wordpress/2011/07/19/company-information-bizzy-for-uk-company-data-and-credit-ratings/). This is another very useful site that I recommend you add to your company information toolkit.
