Companies House is one of the most-visited public records databases in the UK, and for good reason — it’s free, official, and covers every registered limited company. But the way people talk about it online has created a handful of persistent myths about what it actually shows. Some of these assumptions are harmless. Others lead people to make real business decisions — lending money, signing contracts, extending credit — based on a picture that’s far less complete than they think. Here are five of the most common ones, and what’s actually true.
Myth: If a company’s filings look clean on Companies House, its finances are healthy.
Reality: A clean filing history means a company has met its legal obligation to submit accounts on time — nothing more. Plenty of struggling businesses file perfectly compliant paperwork right up until the point they stop trading. Filing compliance is a legal checkbox, not a financial health score.
Myth: Every company’s accounts on Companies House show revenue and profit.
Reality: Only larger companies are required to file full accounts with a profit and loss statement. Small and micro-entities, which make up the large majority of UK limited companies, are legally allowed to file abbreviated accounts that can be little more than a balance sheet — no revenue figure, no profit margin, sometimes barely more than a handful of numbers.
Myth: The numbers on file reflect how the company is doing right now.
Reality: Companies have up to nine months after their financial year ends to file, and many use most of that window. A filing dated this month could easily describe a financial year that ended well over a year ago. For anyone assessing current risk, that lag matters a great deal.
Why This Confusion Persists
Part of the problem is language. People search for things like company accounts, annual reports, or balance sheets, and Companies House shows up as the top result every time, since it genuinely is the authoritative public source. But being authoritative and being complete are two different things — the registry is thorough about what it’s legally required to collect, and silent about everything it isn’t.
The other part of the problem is that the filing categories themselves aren’t well known outside of accounting circles. Terms like “micro-entity,” “small company,” and “dormant company” each come with their own filing requirements, and each one reveals a different amount of financial detail. Someone unfamiliar with these categories has no easy way to tell, just by glancing at a filing, whether they’re looking at a fairly complete financial picture or a bare-minimum disclosure.
This is exactly the gap worth understanding before relying on public filings for an important decision. A clear breakdown of what Companies House financial statements actually contain — and what they routinely leave out, depending on company size and filing category — tends to prevent the specific mistake of treating a compliant filing as proof of financial strength.
Myth: If something looks off, Companies House will flag it.
Reality: Companies House checks that filings are submitted in the correct format and on time. It does not audit the figures for accuracy, and it has no mechanism to flag a company that’s technically compliant but financially struggling. Verification of the actual numbers is left entirely to whoever is reading the filing.
Myth: There’s no need to look anywhere else once you’ve checked Companies House.
Reality: For many everyday purposes — confirming a company exists, checking who its directors are, seeing its filing history — Companies House is genuinely sufficient on its own. But for higher-stakes situations, like extending significant credit or signing a long-term contract, most experienced finance and procurement teams treat it as a starting point rather than a complete picture, supplementing it with a credit reference report, a trade reference, or a direct request for recent management accounts.
What a More Careful Approach Looks Like
None of this means Companies House isn’t worth checking — it absolutely is, and it should usually be the first stop. The difference between a careful check and a false sense of security comes down to a few habits: noting the filing date and asking whether that gap matters for the decision at hand, checking whether the accounts are full or abbreviated, and being honest about whether the situation calls for something more current than a filing that could be well over a year old.
For a small, low-risk purchase, the public record is often genuinely enough on its own. For a bigger commitment — a major client, a long-term supplier, a lending decision — it’s worth treating the filing as the first data point in a slightly longer process, not the final word.
The Bottom Line
None of these myths exist because Companies House is doing anything wrong. It does exactly what it was built to do: maintain a free, public, legally required record of company information. The myths exist because people expect that record to answer questions it was never designed to answer. Once that expectation is corrected, the registry becomes exactly what it should be — a solid first step, not the whole due-diligence process.
The next time a filing shows up looking perfectly clean, it’s worth pausing on one question before treating it as reassurance: clean according to what standard, and current as of when? Those two questions alone tend to separate a genuinely useful check from one that only feels thorough.
