Complaint & Appeal: templates and forms

For a person on a flight that arrived three hours or more late, was cancelled at short notice or on which boarding was denied: the letter claims from the airline the €250, €400 or €600 compensation under Regulation (EC) No 261/2004 for each passenger on the booking, and invites it to negotiate as Spanish Organic Law 1/2025 requires before suing. If the airline does not answer within a month or refuses, a complaint to AESA, Spain's aviation safety agency, is free and its decision binds the airline. Send it by burofax or through the airline's complaint form. In Spanish.

For a person in Spain whom an electricity, gas, phone or other company has signed up, switched from their supplier or charged for a service they did not ask for. The letter denies any consent, recalls that silence is not acceptance and that unsolicited supplies need not be paid for (art. 66 quáter of the Spanish Consumer Protection Act, TRLGDCU), asks for the contract to be cancelled, a return to the previous company and a refund, and invites the company to negotiate as Spanish Organic Law 1/2025 requires. Send it by burofax with certified content. In Spanish.

A Spanish written complaint, in Spanish, for a person treated at a public hospital or health centre in Spain, or a relative, who wants to complain in writing about the care: an excessive wait, a cancelled appointment, poor treatment, a lack of information. It is addressed to the patient service (servicio de atención al paciente), asks for the facts to be looked into and for a reasoned answer within the period set by the region's rules. It is not a claim for compensation. File it at the service itself, at any public registry office, at a post office or online. It holds health data, so it is sold blank and filled in by hand.

For a person who booked a package holiday in Spain or with a Spanish organiser (flight and hotel, a cruise or an agency package) that did not go as agreed: a different hotel, excursions that did not happen, missing services. The letter claims from the organiser or the agency a price reduction for the days affected and compensation for damage (arts. 161 and 162 of the Spanish Consumer Protection Act, TRLGDCU), and invites it to negotiate as Spanish Organic Law 1/2025 requires before suing. Send it by burofax with certified content to the organiser or the agency that sold the trip. In Spanish.

For a consumer in Spain who already asked for a faulty product to be repaired or replaced and did not get it: the company did not do it within a reasonable time, refused, the fault came back or it is serious. The letter requires the seller to reduce the price in proportion or to end the contract and refund the money (arts. 119 to 119 ter of the Spanish Consumer Protection Act, TRLGDCU), and includes the invitation to negotiate that Spanish Organic Law 1/2025 requires before suing. Send it by burofax with certified content. In Spanish.
