Endesa Energía SAU operates one of the largest energy customer-service operations in the country. The main consumer line 800 76 03 33 routes through an automated menu first — to reach a human agent quickly, press 0 repeatedly or say 'agent' when prompted. Wait times are typically shortest mid-week between 9am and 11am local time, longest on Monday mornings and the day after a service outage or product launch.
Endesa segments specialist teams behind the main number: billing, technical support, account security, and an executive escalation desk reachable only after Tier 1 has logged the case. The brand publishes its contact details at https://www.endesa.com/es/atencion-al-cliente; the page is updated periodically with new toll-free numbers, regional offices, and country-specific lines for international customers. Always verify the number on that page before dialing — scam operators routinely buy ads on the brand's name and substitute their own number to harvest payment details.
If Endesa cannot resolve your case after two contacts, the regulator for this category is CNMC — Comisión Nacional (https://www.cnmc.es/). A regulator complaint forces a written response within 30 days and is the single most effective consumer tool in this market.

Common Endesa issues & solutions
Bill higher than expected
Compare usage to the same month last year on the Endesa portal. Smart-meter spikes are often a faulty appliance (water heater, fridge) cycling constantly. Endesa can send an energy audit free of charge for billing disputes.
Power outage in your area
Report at the Endesa outage map or call 800 76 03 33. Most local outages restore within 2–6 hours. If your outage exceeds 12 hours, you may qualify for a service-credit under the regulator's reliability rules.
Switching supplier or tariff
New tariff takes effect on the next meter-read cycle (1–4 weeks). Endesa legally cannot charge an early-exit fee on standard variable tariffs; fixed tariffs may carry a fee specified in the contract.
Meter reading dispute
Submit a self-read via the Endesa app with a photo. If the bill still doesn't match, request a 'meter test' — the regulator requires Endesa to verify within 28 days at no cost if the meter is found accurate (cost passes to you only if you requested without cause).
Direct-debit refund request
If your account is in credit, you can request the surplus back via the Endesa app under 'manage payments'. Refunds settle within 5–10 business days.
Vulnerable-customer registry / priority service
Sign up via 800 76 03 33 or the website. Priority Service Register members get advance notice of planned outages, free meter reading, and emergency support during cold-weather events.

⚠️ Scam advisory

If any of these happen — hang up. Then dial 800 76 03 33 yourself (never call back a number the caller gave you) to verify there is no real issue.
