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 missed deadline costs at least £150 in penalties, 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 — there's no batch filing mechanism at Companies House
• Identity verification must be provided per-company, even though you only verify once

Companies House WebFiling doesn't offer a multi-company dashboard. You log in to each company separately and manage each one independently. 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 only extend your ARD once every 5 years, so shortening is the practical route for alignment.

Track Every Deadline in One Place

Whether you use a spreadsheet, a calendar, or dedicated software, the minimum information to track per company is important. Try our free filing deadline countdown tool to see all your deadlines in one place. 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 (which can't be aligned easily since they're based on incorporation dates), set aside one day per month to check and file any that are due.

Use One Authentication Code Per Company

Each company has its own authentication code. Keep them all in one secure location. If any have expired, request new ones well before your next filing — they arrive by post in 5–7 working days.

Identity Verification Across Multiple Companies

Identity verification is per-person, not per-company. You verify your identity once 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 provide the code at each filing.

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 — there's no batch filing or multi-company dashboard at Companies House
• 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 must be provided per-company at each filing
• A single missed deadline across multiple companies costs 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
