For a customer in Ireland with a problem with a mobile, landline or broadband provider: a slow or broken service, wrong bills, charges you did not agree to, or trouble moving or switching. The letter is the formal complaint ComReg asks you to make first, and asks for a complaint reference number. If the provider does not resolve it within 10 working days, or you are not satisfied with its response, ComReg's Consumer Care team can take it up free. Send it by email or through the provider's complaints channel.

Common questions

When can I take a phone or broadband complaint to ComReg in Ireland?
Once you have made a formal complaint to the provider and have its complaint reference number, which it should give you within two working days. If the complaint is not resolved within 10 working days, or you are not satisfied with the provider's response, contact ComReg's Consumer Care team, free. Raise the complaint with the provider within 12 months of the problem.
What should a complaint to an Irish broadband or mobile provider include?
The dates and length of each fault, what the provider told you each time, any reference numbers, and what you want: a repair date, a refund or credit on your bill, or release from the contract. Keep copies of chats and emails, and screenshots of speed tests or error messages. The clearer the record, the easier it is for ComReg to take the complaint up if you need it.
Can I complain to my phone or broadband provider in Ireland by email?
Yes, where the provider's complaints code of practice allows it; every provider publishes one, saying how to complain — by phone, online chat, email or post. A written complaint by email gives you a dated record. Whatever channel you use, ask for the complaint reference number and keep it, since ComReg asks for it.

    For a traveller whose package holiday — transport and accommodation, or other travel services, sold together — was not as booked. The letter tells the organiser that it is responsible for every service in the package under the European Union (Package Travel and Linked Travel Arrangements) Regulations 2019 (S.I.

  • Chargeback request to your card provider (Ireland)

    For someone in Ireland who paid by debit or credit card and did not get what they paid for — goods never delivered, faulty or not as described, a refund never paid, a payment taken twice — and could not settle it with the trader. The letter asks the card provider to raise a chargeback under the card scheme's rules and to answer in writing. Many providers have a free online dispute form that does the same job; ask the trader first.

  • Complaint to an energy supplier (Ireland)

    For a household customer in Ireland with a problem with an electricity or gas supplier: a high or estimated bill, a wrong meter reading, a payment taken twice, trouble switching, or arrears you dispute. The letter is the formal complaint under the supplier's own complaints code. If its final response does not settle it, the Commission for Regulation of Utilities (CRU) Customer Care Team takes the complaint free. Send it by email or registered post (An Post), with a meter reading.

  • Claim for a delayed or cancelled flight (Ireland)

    For a passenger whose flight arrived three hours or more late, was cancelled with less than 14 days' notice, or who was denied boarding, on a flight covered by Regulation (EC) No 261/2004: every flight from an EU airport, and flights into the EU on an EU airline. The letter claims the fixed compensation — €250, €400 or €600 per passenger, by distance — from the airline that operated the flight. The airline's own claim form and the EU complaint form are free and do the same job. Send it by registered post (An Post) or, where accepted, by email, and keep proof of sending.

  • Complaint about an order that never arrived (Ireland)

    For a consumer in Ireland whose order from an online or high-street trader has not arrived. Under the Consumer Rights Act 2022 the trader must deliver as agreed or, if no time was agreed, within 30 days, and the goods stay at its risk until you have them, so a parcel lost on the way is its problem. The letter gives a final 14 days to deliver, after which you treat the contract as ended and a full refund is due, then the Small Claims procedure (up to €2,000). Send it by email and by registered post (An Post).

  • Complaint about poor work by a builder or trader (Ireland)

    For a consumer in Ireland whose builder, plumber, electrician, garage or other trader did the work badly or not as agreed. Under Part 4 of the Consumer Rights Act 2022 a service must be supplied with reasonable care and skill; the letter asks for the work to be put right at the trader's cost or, where that is impossible or not done, for a price reduction or to end the contract (section 86). It gives 14 days to reply before the Small Claims procedure (up to €2,000). Send it by registered post (An Post) with photos.
