Companies House

14 posts on companies house.

Every UK limited company files its accounts, confirmation statements and officers with Companies House, and all of it is public. These guides explain how the public record works and how to turn it into a source of clients: reading filings, spotting deadlines, and finding the companies that need help before they ask. Leadistry keeps a live, enriched copy of the public record, so each guide ends with something you can actually run.

19 SEPT 2026 · 6 MINCompanies House data for lead generation: what it gives you, and what it leaves outCompanies House publishes every UK limited company, free, with dates that tell you when a firm needs something. It publishes no email addresses, no phone numbers and no websites. This is what the data holds, how to get it, and what it takes to turn a filing into a lead.Read →20 AUG 2026 · 6 MINRegistered office changes: the register's quiet switching signalMost small UK companies use their accountant's address as their registered office. When that address changes, the most common story is that they changed accountant, or are between accountants. Here is how to read the signal, and how to write to it without assuming too much.Read →19 AUG 2026 · 8 MINWhich SIC codes actually describe your customersThe code you need is the one your customer filed, not the one that describes what you sell them.

That published, predictable window is one of the best timing signals in UK B2B sales.Read →29 JUL 2026 · 6 MINWhy filing-traced data beats scraped profiles for UK salesData traced to a statutory filing has a named source, a date, and a legal duty of accuracy behind it.

For UK sales, that difference decides bounce rates, compliance and trust.Read →29 JUL 2026 · 6 MINFirst 90 days: selling to new companies at the right momentA company incorporated this week has no incumbent suppliers and a to-do list full of first-time purchases.

Leadistry finds UK business leads directly from the Companies House public record. You describe who you sell to in a short conversation, in your own words, and the AI sets up what to watch for: there are no filters or search syntax to learn. Every lead arrives complete, with the registered company record, the director's name when it is on the public record, a working website and a business email on a domain confirmed to accept mail. One lead is one lead: anything else we find, such as a LinkedIn profile or their socials, comes with it at no extra cost. If we cannot complete a lead, you never see it and you are not charged for it, and if a first email bounces, the lead is credited back.

Agents keep watching the public record for you. Each morning we add the companies registered at Companies House the day before, and the rest of the record is refreshed from the Companies House monthly file. Every lead comes with a dated reason to get in touch, such as accounts coming due. A company registered this month rarely has a website or a working email yet, so we hold it back until it can actually be reached.

Each lead is written individually, inside your own template with your logo, pictures, video and links: the opening line is about that company and the specific reason it turned up, so no two emails are the same, and your own words carry the offer. Everything waits for you to approve it, unless you switch Autopilot on, in which case your agents' cards go out on their own in your sending hours. Sending starts at five a day from your own mailbox and warms up slowly, and a reply lands in your own inbox, stops the follow-ups and shows on your Desk.

Company data comes from Companies House under the Open Government Licence. Websites and emails are found on each company's own site and checked against the filing, field by field, so every claim traces to a source. Nothing is bought from brokers, and no email address is guessed from a pattern. Leadistry covers UK companies only. Plans start at £29 a month: Growth £29, Pro £69 and Scale £139. The free trial is 25 leads, once (they do not refill), and your first 25 emails from your own mailbox, with no card. Any company or person can ask to be removed at any time.
