What is Companies House?

Companies House is the UK government’s official registrar of companies. It holds the public register of all UK companies and limited liability partnerships (LLPs). Every UK-incorporated business must keep its record with Companies House up to date.

Key Annual Filing Requirements

Statutory Accounts

Every UK company must prepare and file annual statutory accounts in accordance with UK Generally Accepted Accounting Practice (UK GAAP). These accounts must be filed at Companies House and will also form part of the corporation tax filings to HM Revenue & Customs (HMRC). If your UK subsidiary is part of a group that exceeds certain thresholds for turnover, balance sheet size, or number of employees, the accounts may also need to be audited. We offer an integrated solution—accounting and audit services under one roof. Find out more about our statutory accounts services.

Confirmation Statement (CS01)

This is a separate and mandatory filing that confirms the company information held at Companies House is up to date. It must be filed at least once every 12 months, even if there have been no changes to the company.

You must also confirm that your company’s future intended activities are lawful.

Failure to file your confirmation statement can result in penalties or even your company being struck off the register.

At Türner & Co, we take care of this process for you. As an Authorised Corporate Service Provider (ACSP), we are registered with Companies House and can file your confirmation statement on your behalf.

What’s Included in a Confirmation Statement?

  • Company name and number
  • Registered office address
  • Principal business activities (SIC codes)
  • Shareholder details
  • Share capital (statement of capital)
  • Company officers (directors)
  • People with Significant Control (PSC)
  • Registered email address for official communications

 
We ensure all this data is reviewed, correct, and up to date.

Why Use a Professional Filing Service?

Filing the confirmation statement is legally the directors’ responsibility. Using a professional ensures:

  • All filings are timely and accurate
  • Shareholder and PSC registers are correct
  • Registered office and director addresses are used appropriately
  • Your company avoids risk of fines or removal from the register

 
We act as your trusted partner in ensuring regulatory compliance.
