Looking for a Companies House database or list you can actually work with? That is exactly what you build here. Companies House registers 5,486,785 limited companies and PLCs. Our file holds 8,852,655 UK businesses, because it also covers the sole traders, partnerships and branches that never appear on the register. Companies House publishes its register for free, but the download carries no telephone number, no email address and no turnover, and you cannot select part of it. We add phone numbers, mobile numbers, email addresses, revenue and group structure. Filter by SIC code, region and company size and take your file as Excel, CSV or through the API.

is all you can get: the whole register or nothing. Selecting by industry, region or size is work you do after the download.
At CompanyData

UK businesses in our file: the 5,486,785 companies on the register, plus the sole traders, partnerships and branches it does not list.
telephone numbers, plus 904,397 mobile numbers and 1,308,989 business email addresses.
companies with a named director in the same row. Revenue, employee numbers and group structure come with it.
Companies House publishes the whole register for free. The Free Company Data Product is a monthly ZIP of CSV files covering every live company, and it is refreshed within five working days of each month end. What you get is the register: company number, registered address, status, incorporation date, SIC code, filing dates and basic charge information. For checking a company, that is exactly right, and it is hard to argue with free.
Where it stops is the moment you want to do something with it. There is no telephone number, no email address and no turnover in that file. Directors sit in a separate download rather than next to their company. Accounts data only exists for electronically filed accounts, roughly 60% of the 2.2 million filed each year. And you cannot ask for a slice: it is the entire register or nothing, so selecting construction firms in Yorkshire with more than ten staff is work you do yourself, after the download, with no support to fall back on.
Our file starts from that same register and adds the fields it leaves out. Of the 8,852,655 UK businesses in it, 2,676,335 carry a telephone number, 1,308,989 a business email address, 2,682,960 a website and 6,300,196 a named director. You select by SIC code, region, company size or revenue and take the result as Excel, CSV or through the API. Prefer a general UK list without the Companies House angle? See the UK company database. Looking up a single company is free in our Companies House lookup, and for a connection to your own software there is the Companies House API.
