Change of Address Letter (Ireland)

A Change of Address Letter in Ireland puts facts on the record under a formal declaration so they can be relied on by a court, registrar, or third party, and is shaped by the Companies Act 2014.

Under Irish data protection law — the General Data Protection Regulation (GDPR) (Regulation (EU) 2016/679) and the Data Protection Acts 1988 to 2018 — organisations are required to maintain accurate personal data under the accuracy principle in Article 5(1)(d) of the GDPR. An individual who changes address has the right under Article 16 of the GDPR (the right to rectification) to have their address corrected in the records of any data controller holding personal data about them. The Data Protection Commission (DPC), as Ireland's national supervisory authority for GDPR, has noted that address data is particularly sensitive because it can be used to locate an individual. Sending a timely change of address letter confirms organisations can comply with their accuracy obligations and protects the individual from sensitive correspondence — such as bank statements, Revenue notices, medical letters, or court documents — reaching the new occupants of the former address.

For companies registered in Ireland, changing the registered office address requires formal notification to the Companies Registration Office (CRO) by filing Form B2 under section 50 of the Companies Act 2014 within 14 days of the change taking effect. The registered office address must then appear on all company letterheads, invoices, and official business documents under the Companies Act 2014. Failure to notify the CRO or to update business documents after a registered office change may constitute an offence under the Companies Act 2014. For sole traders and partnerships trading under a business name registered under the Business Names Act 1963, any change of principal place of business must also be notified to the CRO by filing Form RBN3.

For individuals in the course of legal proceedings, notifying the court office and all parties to the proceedings of a new address for service is essential to avoid missing critical procedural steps and deadlines. Under the Rules of the Superior Courts (RSC) and the District Court Rules, legal documents are served at a party's last known address. The Irish courts have jurisdiction to grant judgment in default of appearance where a defendant fails to respond to proceedings served at their last known address, even if the defendant has since moved — making it critically important to notify all parties to current or anticipated legal proceedings of a change of address without delay.

For individuals who move address, it is also advisable to notify An Post's address management service and to consider using An Post's mail redirection service (available for up to 12 months) to confirm that correspondence sent to the old address is forwarded to the new address. The letter should include all relevant account, policy, or customer reference numbers so that the recipient can identify and update the correct records promptly, particularly where the individual has multiple accounts or relationships with the same organisation.

An Irish Change of Address Letter is needed whenever an individual or business moves to a new address and wishes to formally notify organisations, institutions, and contacts that their records should be updated.

You need a Change of Address Letter when you are: an individual who has moved home and needs to notify Revenue, the Department of Social Protection, your employer, your bank, your insurance providers, your GP and other healthcare providers, the local authority (for the voter register and property tax records), and An Post of your new address; a company or sole trader that has moved business premises and needs to notify the CRO (by filing Form B2), Revenue, the company's bank and financial institution, regulatory bodies, customers, and suppliers; a contractor, freelancer, or self-employed person who needs to confirm that clients, Revenue, and other business contacts have the correct address for invoices, correspondence, and payments; a tenant who has moved out of a rented property and needs to notify the previous landlord, utility providers, An Post, and other organisations of their new address; a company that is changing its registered office address (which must be notified to the CRO within 14 days under section 50 of the Companies Act 2014); or a person engaged in ongoing legal proceedings who needs to notify the court, their solicitor, and the other parties of a new address for service.

A change of address letter is also important for confirming continued receipt of important documents — such as tax assessments, election polling cards, renewal notices for insurance and vehicle registration, and correspondence from financial institutions. Failure to update address records can result in missed deadlines, lapses in insurance coverage, failure to receive electoral registration notices, and other practical difficulties.

For convenience, many Irish organisations now provide online portals or dedicated procedures for updating address records — including Revenue's myAccount, the Department of Social Protection's MyWelfare portal, and online banking platforms. However, a formal written change of address letter remains important for organisations that do not provide online update facilities and as a record of the notification for the sender's own files.

For businesses, a change of address requires updating the company's letterhead, website, email footers, and any promotional materials to reflect the new address promptly. Under the Companies Act 2014 (and the Business Names Act 1963 for sole traders and partnerships trading under a business name), the registered address must appear on all official correspondence, invoices, and other business documents. A failure to update these materials after a change of address could create confusion for clients and business partners and may technically constitute a breach of the statutory disclosure requirements under the Companies Act 2014.

Under Irish law, the Data Protection Act 2018 and GDPR Article 6 govern personal data in this document. The Consumer Rights Act 2022 protects individuals in consumer transactions. Section 67 of the Land and Conveyancing Law Reform Act 2009 applies to personal property matters. The Circuit Court and District Court have jurisdiction over personal disputes under the Courts (Supplemental Provisions) Act 1961. The Commissioners of Irish Lights and Revenue Commissioners may have compliance roles depending on the transaction type.

A well-drafted Irish Change of Address Letter should contain the following essential elements to confirm it is effective and that the recipient can act on it promptly.

The sender identification clause must state the sender's full legal name, date of birth (for government bodies such as Revenue or the Department of Social Protection that use it for identity verification), and — where relevant — the sender's PPS number, customer reference number, account number, or policy number. Where the sender is a company, the company name, CRO registration number, and the name and title of the authorised signatory must be included.

The old and new address clause must state both the full former address (including Eircode) and the full new address (including Eircode), so the recipient can identify and update the correct record. The Eircode — Ireland's national postcode system, administered by An Post under the Eircode Act 2011 — should be included for both addresses to confirm accuracy and to assist with automated record-matching in large organisations' databases.

The effective date clause specifies the date from which the new address applies — that is, the date the sender moved or will move. This is important so the recipient knows from which date to update their records and to which address any correspondence should be sent.

The update request clause formally requests that the recipient update their records to reflect the new address, and asks the recipient to confirm in writing (or by email or online) that the update has been made. Retaining written confirmation from each organisation is important evidence that the notification was given, which is useful if any organisation fails to update its records and the individual suffers adverse consequences as a result.

The GDPR accuracy clause (where appropriate) references the sender's right to rectification of inaccurate personal data under Article 16 of the GDPR (Regulation (EU) 2016/679) and requests that the recipient update their records in compliance with the accuracy principle under Article 5(1)(d) of the GDPR. This clause is particularly relevant when writing to organisations that process significant volumes of personal data, such as banks, Revenue, insurance companies, and healthcare providers regulated by the Data Protection Commission (DPC).

The forwarding request clause (where applicable) requests that the recipient forward any correspondence sent to the old address — for a specified transition period — to the new address, to confirm that no important documents are missed during the weeks immediately after the move when not all organisations may have updated their records.

The signature clause provides for the sender's handwritten signature and printed name. For companies, the letter should be signed by the company secretary or a senior officer, with their name and title printed below the signature. For a company change of registered office, the letter should be accompanied by — or should cross-reference — the Form B2 filed with the CRO under section 50 of the Companies Act 2014. The Companies Act 2014 requires that the new registered office address appears on all company letterheads, invoices, and official documents from the effective date of the change, and failure to do so is an offence.

The delivery method should be chosen to provide proof of receipt — registered post through An Post, courier with signed delivery, or email with read-receipt or delivery confirmation. For government bodies such as Revenue (via myAccount on revenue.ie), the Department of Social Protection (via MyWelfare), or the local authority (for the Register of Electors), the organisation's own online update portal is often the most efficient channel and should be used in preference to a posted letter where available.
