The data we hold is all publicly available so one thing you could do is use Companies House. Since every company in the United Kingdom is required by law to file here you can rely on this data as it’s a matter of public record.
However, Companies House whilst being the source of some of the data – is not the most user friendly – even though they have made massive advances on this in recent years.
Searching for companies individually is easy, so getting information on one company is easy, however once you start doing this for multiple companies, you will soon realise the limitations. Also, in terms of user experience it leaves a lot to be desired, that is why our customers love us.
