Portugal electricity contract and meter procedures
Short answer: E-REDES operates the distribution network; your chosen supplier manages the contract and bills. Switching is free and supply should not be interrupted.

E-REDES, supplier and CPE

E-REDES handles the distribution network, technical faults and meters; the supplier handles your contract and bills. The CPE identifies the delivery point.

Contracting and switching

Identity, NIF, occupancy evidence, CPE and payment details may be requested. ERSE states that switching is free, should not interrupt supply and must be completed within three weeks. An existing loyalty term may still create an exit charge.

Contracted power and time tariffs

Contracted power affects simultaneous appliance capacity and the fixed charge. Use ERSE’s power simulator. Compare single, dual and triple time tariffs against your actual usage.

Bills, readings and outages

Separate energy, power, network and tax items. Submit readings when remote readings are unavailable. Contact the network operator for a network fault and the supplier for billing issues.

Social tariff and deposits

Check current social-tariff conditions with ERSE. A security deposit is not an automatic condition for every new low-voltage household contract.
