Many company directors in London register a limited company but do not start trading immediately. Even if the company remains inactive, it still has legal reporting obligations. One of the most important requirements is to file dormant company accounts with Companies House.
Failing to submit these accounts correctly can lead to penalties and compliance issues. This guide explains how to file dormant company accounts in London without mistakes, what the filing process involves, and how a small business accountant can help ensure full compliance.
Understanding Dormant Companies in the UK
A dormant company is a business that has had no significant accounting transactions during the financial year. In simple terms, the company exists legally but does not actively trade or generate revenue.
According to Companies House rules, a company is considered dormant if it has no business activity other than specific allowed transactions such as filing fees or share capital payments.
Even if the company is dormant, directors must still file annual accounts with Companies House.
Why Filing Dormant Company Accounts Is Important
Many directors assume that inactive companies do not need to submit financial reports. This assumption is incorrect. Every registered company in the UK must file accounts each year.
Filing dormant company accounts helps maintain the company’s legal status and ensures transparency in the UK corporate system.
Failure to file accounts may result in:
• Financial penalties
• Late filing fines from Companies House
• Possible company strike off proceedings
• Damage to director credibility
Understanding the filing process helps prevent these risks.
Step-by-Step Guide to File Dormant Company Accounts in London
Step 1: Confirm Your Company Is Truly Dormant
Before filing dormant accounts, confirm that your company has had no significant transactions during the financial year.
A company may lose dormant status if it has:
• Business income
• Operating expenses
• Payroll transactions
• VAT activity
If your company has traded during the year, you must file full company accounts instead.

Step 2: Prepare Dormant Company Accounts
Dormant accounts are simpler than active company accounts. They usually include:
• A basic balance sheet
• Notes confirming the company is dormant
• Director confirmation statement
These accounts must still follow UK accounting standards and Companies House formatting requirements.
Step 3: Submit Accounts to Companies House
Dormant accounts can be filed through:
• Companies House WebFiling
• Accounting software
• Professional accounting services
Most small businesses prefer digital filing to reduce errors and speed up processing.
Step 4: File Your Confirmation Statement
Along with dormant accounts, companies must submit a confirmation statement each year. This document confirms that company information such as directors and shareholders remains accurate.
Step 5: Meet the Filing Deadline
Dormant company accounts must be submitted within 9 months after the end of the financial year.
Missing this deadline leads to automatic fines starting from £150.
Common Mistakes When Filing Dormant Company Accounts
Many directors make avoidable mistakes during the filing process.
Incorrectly Declaring Dormant Status
If your company had transactions during the year, you cannot file dormant accounts.
Missing the Filing Deadline
Even a one-day delay can trigger late filing penalties.
Incorrect Balance Sheet Information
Errors in share capital or financial figures can cause Companies House to reject the filing.
Forgetting the Confirmation Statement
Some directors file accounts but forget to submit the annual confirmation statement.
Using Incorrect Filing Software
Improper formatting or submission errors may lead to rejected filings.
Working with a professional small business accountant can help prevent these mistakes.

When Dormant Companies Need to File Full Accounts
Sometimes companies start trading during the year without updating their reporting approach.
You must file full company accounts if your business:
