The client transitions worth catching the night they happen
Clients change their companies without telling their accountant. An officer is appointed, a charge is registered, the accounting reference date moves, the company is proposed for strike off. Each is filed at Companies House and none generates a phone call. The gap between the change happening and the firm finding out is where the problems live.
What actually changes without warning
| Change | Why it matters to you |
|---|---|
| Officer appointed or resigned | Affects who can authorise, who signs, and your AML position on the people behind the company |
| PSC change | Control has moved. Your client due diligence may no longer be current. |
| Charge registered | The company has borrowed, secured on its assets. Relevant to the accounts, and to any advice you are giving. |
| Accounting reference date changed | Every deadline you hold for that client just moved |
| Registered office changed | Correspondence may be going somewhere you do not know about |
| Proposed strike off | The most urgent of all, with a short window to object |
| Company name changed | Your records, engagement letter and filings now disagree with the register |
Why a quarterly check is not enough
Because the two changes that matter most have clocks on them.
Accounting reference date changes
A client who shortens or extends the period has changed the filing deadline. If your practice system still holds the old date, you are working to a deadline that no longer exists — and finding out late means finding out with no time.
Proposed strike off
A first gazette notice starts a short window in which objections can be made. A company can be struck off with tax outstanding, assets still in its name, and a director who did not understand what was happening. Catching that notice quickly is the difference between a phone call and an application to restore.
On a quarterly cycle, both of these can be over before you look.
Why clients do not tell you
Not obstruction. It simply does not occur to them:
- They used a formation agent's portal to add a director and assumed it was handled
- They changed the year end to line up with a funder's request, thinking it was administrative
- Their bank registered the charge, so from the client's side nobody filed anything
- The strike off notice went to a registered office they no longer check
From the client's perspective a form was submitted and the matter closed. The consequences land on you.
The AML angle
Officer and PSC changes are not just administrative. Your client due diligence is based on who controls the company. When that changes and you do not know, your file is out of date on the point regulators care about most.
Finding out at the next review is finding out late. The date you should have known is the date it was filed.
What a nightly sweep gives you
Not more data. Earlier data, and only where something moved:
- Reference date changes reach your deadlines the same week, not the next cycle
- Strike off notices reach a partner while the objection window is open
- Officer and PSC changes trigger a due diligence refresh at the right moment
- Charges surface before they appear as a surprise in the accounts
The value is not that you eventually learn about these. It is that you learn on the day, when there is still a choice to make.
Turning it into a habit
Fynvro OS syncs Companies House daily for every client and surfaces transitions as they happen, routed by severity — a strike off notice reaches a partner, a registered office change reaches the team.
Where a change moves a deadline, the deadline moves with it, so the firm is not working to a date the register has already changed.
Frequently asked questions
How do I find out when a client changes their company details?
Companies House publishes filings publicly, but it will not tell you unless you look. Firms either check manually, subscribe to a follow service, or use software that sweeps the register automatically.
What happens if a client changes their accounting reference date?
The filing deadline changes with it. Any deadline you hold for that client becomes wrong until you update it, which is why catching the change early matters.
How long is the strike off objection window?
A first gazette notice starts a defined period during which objections can be made. Because it is short, the practical requirement is to hear about it quickly — check Companies House guidance for the current period.
Does a PSC change affect our AML obligations?
It can. Client due diligence rests on who owns and controls the company, so a change in control is a reason to revisit the file.
Why does a registered charge matter to the accountant?
It means the company has borrowed against its assets. That affects the accounts, any advice you are giving, and your understanding of the client's position.
