Consumer Complaints in Portugal Hit 485,000 as Regulators Nearly Double Fines to Five Million Euros

Portugal's official complaints system processed 485,203 formal consumer complaints in 2025, a 9.1 percent increase on the previous year, according to figures released Monday by the Direção-Geral do Consumidor (DGC), the national consumer protection authority.

More striking than the complaint volume is what happened on the enforcement side: regulators applied fines totalling 5,003,536 euros last year, an 86 percent increase from the 2,684,722 euros levied in 2024.

Where the Complaints Are Coming From

The sectors attracting the most complaints are the ones that matter most to daily life. Food safety and retail, overseen by ASAE (the food and economic safety authority), topped the list with 229,365 complaints — nearly half of all filings and a 19.8 percent jump from 2024. Electronic communications and postal services, regulated by ANACOM, followed with 102,629 complaints.

Transport complaints surged by 43.9 percent, reflecting the disruptions from the Middle East energy crisis and its cascading effects on fuel prices, flight schedules, and public transit reliability. The energy sector (ENSE) saw a 13.3 percent increase, likely tied to billing disputes during a volatile year for electricity and gas prices.

Not everything went up. Banking complaints filed with the Bank of Portugal fell 5 percent to 21,161 — potentially a sign that the mortgage rate relief from ECB rate cuts eased some pressure. Aviation complaints (ANAC) also dipped 2 percent to 14,843, and transport authority (AMT) filings fell 3.1 percent to 26,933.

Electricity and gas complaints dropped a significant 31.4 percent, despite higher prices — possibly because consumers had already switched providers or adjusted consumption patterns.

The Digital Shift

One trend stands out: 2025 was the first year the electronic version of the complaints book outpaced expectations, recording more digital filings than ever since its creation. Of the 485,203 total, 261,037 were filed using the traditional paper book, meaning roughly 224,000 came through the digital platform at livroreclamacoes.pt.

This matters for expats because the digital system accepts complaints in Portuguese only, which creates a practical barrier. However, the shift toward digital filing also means complaints are processed faster — the regulator receives them electronically in real time, whereas paper complaints require the business to forward them within 15 days.

Five Million Euros in Fines

The 86 percent increase in fines breaks down into two categories. Of the total 5,003,536 euros, 2,874,722 euros came from sector-specific regulatory violations triggered by consumer complaints — meaning the complaint directly led to a fine against the business. The remaining 2,128,814 euros were penalties for violations of the complaints book regime itself: businesses that refused to provide the book, failed to forward complaints, or retaliated against consumers.

This enforcement ramp-up suggests regulators are taking the system more seriously, not just as a consumer outlet but as a compliance mechanism. For businesses operating in Portugal — including those run by foreign entrepreneurs — the message is clear: ignoring a complaint filed in the Livro de Reclamações can now carry real financial consequences.

The Expat Angle

Portugal's complaints book system is unlike anything most foreigners have encountered. Every business with a physical or online presence that serves the public is legally required to have one. This includes restaurants, shops, telecoms providers, health insurance companies, landlords (in certain contexts), and public services.

For expats navigating a new country, the Livro de Reclamações is one of the most powerful consumer tools available. Filing a complaint is free, creates a legal paper trail, and triggers a mandatory response from the relevant regulator. It is the closest thing Portugal has to a universal consumer enforcement mechanism — and based on the 2025 data, it works.

Understanding how to use this system is particularly important for those dealing with utility billing disputes, telecoms issues, blackout-related compensation claims, or poor service from immigration-related services. The DGC data makes clear that complaints are not just symbolic — they drive enforcement action worth millions.
