How to Change Your Registered Office: Form B2

Quick answer

The directors approve the new address, and the company files Form B2 with the CRO on CORE within 14 days. There's no CRO fee. The change takes legal effect only when the CRO registers the form, and Revenue must be told separately.

The steps

  1. Agree the new address with its owner or provider.
  2. Directors approve the change, usually by board resolution or minute.
  3. File Form B2 on CORE within 14 days of the change. It's free.
  4. Tell Revenue through ROS, because the CRO doesn't pass the change on.
  5. Update stationery, invoices, website and email signatures that show the registered office.

When it takes effect

The CRO's guidance is that a change of registered office becomes legally effective only when the CRO has registered the B2. Until then, documents sent to the old address on the register still count as delivered, so don't delay filing.

Using a Registered Office Agent

If the new address belongs to a CRO-approved Registered Office Agent, the B2 names the agent and records the company's consent to the appointment. Ending the arrangement later takes another B2, signed by an officer of the company.

New companies

A company being set up gives its registered office on the incorporation form (Form A1), so no B2 is needed.
