Companies House updates list of authorised corporate service providers
Companies House has published an updated list of Authorised Corporate Service Providers (ACSPs), also known as authorised agents. The update was published on 9 November 2026 and is relevant to UK firms that use accountants, solicitors or other agents to handle filings.
What ACSPs do
ACSPs are agents that have registered with Companies House to file information, or carry out other activities, on behalf of clients. To qualify, an agent must be supervised by a UK Anti-Money Laundering (AML) supervisory body.
Limits of the list
- It covers only agents that asked for their details to be published, so it may not include every registered ACSP.
- It is not updated on a set schedule, so entries may be incomplete or out of date.
- Companies House does not endorse or recommend any agent on it.
Checks before appointing an agent
Companies House advises businesses to check its separate list of ceased and suspended ACSPs before using an agent. Any agent on that list cannot act as an ACSP.
It also recommends researching an agent's reputation and experience, and contacting them directly or checking their website. One point added to the guidance is to ask whether an agent needs to carry out checks in person or can provide services remotely.
The guidance also links to information on using an ACSP to verify your identity for Companies House.
