Acceptable Use Policy

Last updated: 26 September 2026

This policy sets out what you may and may not do when using DormantFile. By using the service, you agree to comply with this policy.

Permitted use

DormantFile is provided for the sole purpose of filing annual accounts (dormant accounts or FRS 105 micro-entity accounts, for companies and LLPs alike) with Companies House, and nil CT600 returns (companies) or nil SA800 partnership returns (LLPs) with HMRC, on behalf of UK limited companies and limited liability partnerships (LLPs) that are not trading — whether genuinely dormant or non-trading with limited transactions such as a loan being repaid. The tools that come with it — deadline reminders and register monitoring, the free checks, the compliance assistant, the letter decoder and penalty appeal letters — are provided for that same purpose.

You must not

Use the service to file returns for companies or LLPs that are trading, or that are required to file full or small-company (FRS 102) accounts.
File dormant accounts for a company or LLP that is not genuinely dormant, or micro-entity accounts for a company or LLP that does not qualify as a micro-entity.
Submit false, misleading, or fraudulent information to HMRC or Companies House.
Use another person's HMRC Gateway credentials or Companies House authentication code without proper authorisation.
Upload to the letter decoder a letter that was not sent to a company or LLP you are entitled to act for, or that contains another person's personal information you have no right to share.
Attempt to access, interfere with, or disrupt any part of the service, its servers, or connected networks.
Reverse engineer, decompile, or attempt to extract source code from the service.
Use the service in any way that breaches applicable law or regulation.
Buy or send a penalty appeal letter for a company or LLP you are not entitled to act for, or sign one in a name that is not your own.
Put into an appeal letter any statement you know to be untrue, or have no reasonable grounds to believe is true. The letter goes to HMRC or Companies House over your signature.
Include in an appeal another person's health, bereavement or other personal information that you have no proper reason to share.
Create multiple accounts to circumvent subscription limits.

Consequences

If we reasonably believe you have breached this policy, we may suspend or terminate your account without notice. We may also report suspected fraudulent filings to HMRC or Companies House, and we report suspected money laundering to the National Crime Agency — see our anti-money laundering policy for the due diligence we carry out.

Reporting

If you become aware of any misuse, contact us at hello@dormantfile.co.uk.

Changes

We may update this policy from time to time. Your continued use of the service after changes take effect constitutes acceptance of the updated policy.
