The Companies House reform impact on businesses is huge and already being felt by UK limited companies.
Now, directors and people with significant control must verify their identity and businesses need an appropriate registered office and email address. Companies House can also query or challenge information that looks incorrect.
If you are trying to understand the Companies House reform impact on businesses, you are in the right place.
Let us break down exactly how the ongoing changes will alter your compliance routine!
What Is The Companies House Reform, Exactly?
Companies House has been given new legal powers and new jobs to do. Previously, businesses used to send information to Companies House, and they used to store it. But nobody really checked whether it was true.
That basically has changed now.
Now, Companies House is no longer just a place where companies send information and accounts once a year.
Under the Economic Crime and Corporate Transparency Act 2023, Companies House has been given stronger powers. The power to query information, reject filings that look wrong, and remove false or misleading data from the register.
Companies House reform impacts on businesses also involve identity checks so the register actually reflects real people.
The entire goal of this legal update is to stop fraud and clean up the public register.
You must know that the Companies House reform impacts UK businesses in stages rather than all at once. Some parts are already in force. Some kicked in earlier in 2026. Some won’t land until 2027 or 2028.
What Is The Full Timeline For the Companies House Reform Impact On Businesses?
If you want a clear look at the actual Companies House reform impact on businesses, you need a concrete timeline. Here is that timeline to help you understand what is already live and what you still need to prepare for.
| Date | What Changed |
| 4 March 2024 | A registered office must be an “appropriate address” (no PO boxes). Registered email address required. Lawful purpose statement added to confirmation statements. |
| 1 May 2024 | First round of fee increases. Digital incorporation rose from £12 to £50. |
| 18 November 2025 | Identity verification became a legal requirement. New directors and PSCs must verify from this date onward. 12-month transition period opened for existing directors and PSCs. |
| 1 February 2026 | Second round of fee increases across incorporation, confirmation statements, and ACSP registration. |
| 17 November 2026 | Final backstop date for the identity verification transition period (though individual deadlines are triggered earlier by each company’s confirmation statement due date). |
| No earlier than November 2027 | Identity verification for people filing documents and requirements for third-party agents to be registered as ACSPs are expected to be introduced, subject to the final implementation timetable. |
| 1 April 2028 | All companies will need to file annual accounts using commercial software. Small companies and micro-entities will need to file profit and loss accounts, although they will be able to opt out of publication on the public register. The option to file abridged accounts will be removed. |
It is worth noting that a few of these dates have shifted over time. For instance, the accounts filing changes were originally due to land in April 2027. However, the government decided to pause the rollout to give businesses more time to prepare. As a result, they officially confirmed in June 2026 that the new rollout date will be April 2028.
How Does Companies House Reform Impact On Businesses?
The current rules under the Companies House reform impact on small businesses focus heavily on who controls a company and where that business is located.
1. Identity Verification (Already Live, Deadline 17 November 2026)
One of the biggest changes of the Companies House reform impacts UK businesses is the introduction of mandatory identity checks. Since 18 November 2025, any new director or PSC has needed to verify their identity before appointment. If you are already a director or PSC, your individual deadline depends on your role and circumstances. Existing directors generally provide their personal code with the company’s next confirmation statement, while PSCs have a separate 14-day period based on their circumstances.
Verification takes about 10 to 15 minutes through GOV.UK One Login, or your accountant can handle it if they’re registered as an Authorised Corporate Service Provider (ACSP). Once done, you get a personal code that covers every company you’re involved with. So it is a one-off job.
If you are both a director and a PSC of the same company, you must provide your personal code separately for each role. The director requirement is linked to the company’s confirmation statement, while the PSC requirement follows the separate 14-day PSC process.
2. Higher Companies House Fees (Already Live, In Force Since 1 February 2026)
Digital incorporation jumped from £50 to £100. Confirmation statements went from £34 to £50 digitally, and £110 on paper. ACSP registration now costs £63.
Oddly, voluntary strike-off got cheaper, dropping to £13 digitally. This is because Companies House wants unused dormant companies closed down rather than left cluttering the register.
It is another direct Companies House reform impact on businesses aiming to clean up stale registry data.
3. Registered Office And Lawful Purpose Rules (Already Live Since March 2024)
This is older than the other changes. Your registered office must be an appropriate address. Yes, the address must be a physical location where legal documents can be delivered and physically acknowledged by someone representing the firm.
Companies can no longer use PO boxes or completely unmonitored virtual spaces as a registered office address.
Failure to maintain an appropriate registered office can lead to Companies House taking enforcement action, including changing the address to a default address and potentially starting strike-off proceedings if the company does not provide an appropriate replacement.
Alongside this, you must keep a registered email address on file. Separately, companies must confirm on their confirmation statement that their intended future activities are lawful. The government will use it to send you official warnings, updates, and filing notices. You must monitor this inbox regularly.
The Companies House reform impact on limited companies is about better record-keeping, better evidence, and, of course, more responsibility for directors.
4. Presenter Verification For Agents (Not Yet In Force, No Sooner Than November 2027)
This one’s different from the director and PSC verification above. It applies to anyone filing documents on a company’s behalf. This also includes accountants and agents.
It was originally expected around November 2026 but has been pushed back by a year.
So for now, nothing to act on here. This is something you should be keeping an eye on for next year. Understanding the Companies House reform impact on businesses means tracking these shifting agent deadlines.
5. Profit And Loss Filing For Small Companies (Not Yet In Force, From 1 April 2028)
This is the big one everyone’s heard about but confused the timeline on. Small companies and micro-entities will need to file a profit and loss account with Companies House. This is something that’s currently optional.
It was originally planned for April 2027, paused in January 2026, then confirmed again for April 2028.
So no, this isn’t affecting your 2026/27 filings. It’s a 2028 change, and there’s genuinely time to prepare properly.
6. Software-Only Accounts Filing And The End Of Abridged Accounts (Not Yet In Force, From 1 April 2028)
Alongside the profit and loss change, the free WebFiling service and postal filing will close for accounts. This means that everyone needs to file using commercial software in iXBRL format from April 2028. The option to file “abridged” or “filleted” accounts, the simplified versions many small companies use, disappears at the same time.
Again, this sits in 2028, not now. But if you currently rely on abridged accounts to keep your figures private, it’s worth understanding that Companies House is bringing changes to accounts filing from April 2028.
Managing Companies House Reform Impact On Businesses: What To Actually Do
Managing Companies House reform impact on businesses comes down to a few simple habits.
First, you need to check your confirmation statement date because that’s what determines your real identity verification deadline.
Get every director and PSC verified through GOV.UK One Login, or ask your accountant if they’re an ACSP and can handle it for you. Don’t leave it until the week your confirmation statement is due.
Check your registered office actually meets the appropriate address standard.
Also, make sure to budget for the new fee levels in your annual running costs.
