Request Letter of Authority for Co Sec to File on Director/PSC’s Behalf at Companies House 
Part of the rationale behind the Economic Crime & Corporate Transparency Act 2023 (ECCTA), is to ensure that the register at Companies House contains accurate information and is updated in a timely manner. The ECCTA is introducing new rules for those filing on behalf of someone else at Companies House. From Spring 2026, an individual may only deliver a document on behalf of another firm or individual if the individual delivering it is ID verified (unless the individual is either an Authorised Corporate Service Provider (ACSP) or an employee of an ACSP) and is not a disqualified person or filing on behalf of a disqualified person. This will therefore impact a company secretary’s ability to file on a company’s behalf or on behalf of the company’s directors and PSCs.
The ECCTA gives Companies House new and enhanced powers to help disrupt economic crime and the ID verification regime is a key component of this. From Spring 2026, any company secretary wishing to file at Companies House will need to identity verify.
In addition, with the abolition of certain statutory registers, there will be more filings that must be made directly with Companies House usually within 14 days and failure to do so is a breach that may attract serious consequences.
Considering this, it is strongly recommended that any individual delivering documents on behalf of another, is given specific authority to do so by the company or individual concerned.
This letter of authority may be used for this purpose in relation to an individual director or PSC. This letter explains to a director or PSC the new rules in relation to making filings at Companies House and requests that the individual authorises the company secretary to file on their behalf. This letter should be accompanied by an acknowledgement form that the director or PSC should sign and return to the Company confirming they agree.
