Managing Multiple Companies on Companies House: Director's Guide

Running one UK limited company means two annual filings and occasional event-driven changes. Running three means six annual filings, each on a different schedule. Running ten — common for portfolio landlords with SPV structures — means twenty annual deadlines, each with its own countdown.

The challenge isn't knowing what to file. It's tracking when to file across every entity without one slipping through. A single late set of accounts costs a private company at least £150 in penalties (£750 for a public company), and the more companies you manage, the higher the probability that one gets forgotten.

Why Multi-Company Filing Is Hard

Each company has its own independent timeline:

• Different incorporation dates create different confirmation statement cycles
• Different accounting reference dates create different accounts deadlines
• Each company files independently — each filing is made company by company
• Identity verification must be provided per-company, even though you only verify once

A single Companies House WebFiling account can hold all the companies you're authorised to file for (its 'Your companies' page), but each filing is still made company by company, and Companies House's email reminders are managed for each company separately. For directors with 3+ companies, this creates a fragmented picture where it's easy to miss that one entity's confirmation statement slipped past its deadline three weeks ago.

The Portfolio Landlord Problem

Portfolio landlords operating through SPV structures face a specific version of this challenge:

• Each SPV is a separate company with its own filing obligations — even if it only holds one property and has no active transactions
• Dormant SPVs still file — annual accounts (free, simplified) and a confirmation statement (£50 per company)
• SPVs are often incorporated at different times as properties are acquired, creating scattered deadlines throughout the year
• The penalty risk compounds — a £150 penalty on each of 5 SPVs is £750 in avoidable fees

Example: A landlord with 5 SPVs incorporated between 2019 and 2024 has 5 different ARDs and 5 different confirmation statement cycles. That's 10 separate filing deadlines per year, none of which align.

Strategies for Multi-Company Management

Align Your Accounting Reference Dates

You can change each company's ARD using form AA01 at Companies House. Aligning all your companies to the same ARD means all annual accounts are due at the same time. This doesn't eliminate the work, but it concentrates it into one period rather than spreading deadlines across the year.

How to align:

1. Choose a target ARD (many directors use 31 March to align with the tax year)
2. File an AA01 to shorten each company's current financial year to end on your chosen date
3. Shortening has no limit on frequency — you can shorten as many times as needed

Note: You can't extend your ARD again within 5 years of the end of a period that was previously extended, so shortening is the practical route for alignment.

Track Every Deadline in One Place

Whether you use a spreadsheet, a calendar, or dedicated software (see how to choose company secretarial software if you're weighing that up), the minimum information to track per company is important. Our free filing deadline countdown tool estimates one company's accounts and confirmation statement deadlines at a time, shows when the identity-verification transition period ends, and exports the dates to your calendar, so you can build one calendar across all your companies. Here's what to track:

Company	Company No.	ARD	Accounts deadline	Last CS date	CS deadline	ID verified?
ABC Trading Ltd	12345678	31 Mar	31 Dec	15 Jun 2025	29 Jun 2026	Yes
123 Property SPV	87654321	30 Sep	30 Jun	1 Mar 2025	15 Mar 2026	No

Update this after every filing. Set reminders at 30 and 14 days before each deadline.

Batch Your Filings

If you've aligned your ARDs, batch your accounts filings — prepare and submit all companies in the same session. For confirmation statements, each company's cycle runs 12 months from its last confirmation statement date (or from incorporation, for its first statement). You can bring them into line by filing early: you choose a new confirmation statement date, and the next review period starts the day after it. The £50 annual fee follows a separate payment period that can't be changed, so an extra statement filed within the same payment period costs nothing more. Until they're aligned, set aside one day per month to check and file any that are due.

The same monthly slot is the right place for one-off company changes, which are easy to lose track of across a portfolio: changing a company name, changing your registered office, or appointing and removing officers. Each is per-company. Director appointments and removals must be notified within 14 days, and a name-change special resolution must reach Companies House within 15 days. A registered office change has no deadline but only takes effect once Companies House registers it.

Use One Authentication Code Per Company

Each company has its own authentication code. Keep them all in one secure location. If you don't have the code for one of them, request it well before your next filing, not when the accounts are due — it's posted to the company's registered office and can take up to 10 working days to arrive.

Identity Verification Across Multiple Companies

Identity verification is per-person, not per-company. You verify your identity once (our identity verification guide covers how) and receive one personal code. But you must provide that code separately for each company when filing its confirmation statement.

If you're a director of 5 companies, you include your personal code in all 5 confirmation statements. If you have co-directors who are also directors of your other companies, each person verifies once and provides their code per-company.

The common mistake is thinking verification is done once and applied automatically. It isn't — you actively link the code once for each company: with that company's next confirmation statement (or the appointment filing for a new director).

When to Consider Professional Help

Managing filings across multiple companies is administrative work with serious consequences for errors. Consider professional help when:

• You have 10+ entities — the administrative burden becomes a meaningful time cost
• You regularly miss deadlines — repeat offender penalties double, making the cost of errors compound
• Your companies have complex structures — holding companies, subsidiaries, and group structures add filing complexity
• You're adding new companies frequently — each new SPV adds another set of deadlines to track

A company secretary or accountancy firm can handle all filings across all entities, typically for a fixed annual fee per company. Compare that fee against the penalty cost of missing even one deadline.

Key Takeaways

• Each company files independently, so you need your own cross-company deadline tracker
• Align ARDs to concentrate deadlines and reduce the chance of one slipping through
• Track every company's deadlines in one place — spreadsheet, calendar, or dedicated software
• Identity verification is per-person but the code must be linked once per company (with each company's next confirmation statement)
• A single late set of accounts costs a private company at least £150 — the more entities you have, the higher the risk
• Consider professional help if you have 10+ entities or you're regularly missing deadlines
