Setting up electricity, water and internet in san sebastián is usually straightforward, but each service follows a different process. Whether you are renting a flat in Donostia-San Sebastián or moving into a newly purchased home, arrange the utilities as soon as you have access to the property. The most important details are the supply address, existing account information and your Spanish contact and payment details.
Before arranging any service
Ask the landlord, estate agent or previous owner whether the supplies are active. Take photographs of the electricity meter and water meter on the day you move in, including the readings and meter numbers. Keep a copy of the handover document showing the date you accepted the property. This helps prevent you being charged for consumption from before your tenancy.
You will normally need your passport or national identity card, NIE if available, Spanish address, a telephone number, email address and a Spanish bank account for direct debit. Some companies accept an international account temporarily, but this depends on the provider. Renters should also have a copy of the rental contract; owners may be asked for the escritura or another document proving ownership.
How to arrange electricity in San Sebastián
Electricity is supplied through a retailer, while the local distribution network maintains the cables and meter. You can choose a retailer and tariff, but you cannot choose the distributor for your address. If the property already has power, changing the account holder is generally quicker than requesting a new connection.
Request the following information from the landlord or previous account holder:
- The CUPS, a supply code beginning with ES that identifies the property.
- The current contracted power in kilowatts.
- The latest electricity bill and meter reading.
- The name of the current retailer and the distributor, if known.
Compare the total price rather than only the advertised energy rate. Check the contracted power charge, taxes, standing charges, contract length, cancellation conditions and any maintenance package. Spanish domestic electricity uses the 2.0TD access tariff, with different network periods; a retailer may offer a fixed-price or time-based plan. If you regularly use electric heating, an induction hob or an electric vehicle, ask whether the existing power is sufficient before changing it.
Do not cancel an active supply unless you have been advised to do so. A change of account holder normally avoids reconnection charges and leaves the electricity available when you arrive. If the supply has been disconnected, the retailer will explain whether a new contract or technical inspection is required.
Arranging water and wastewater
Water in San Sebastián is managed through the local municipal and regional water-service arrangements, so the billing organisation can depend on the property and the service contract. Check the latest bill or ask the Donostia-San Sebastián municipal water service which office or company handles your address. This is more reliable than assuming that every neighbourhood has the same procedure.
For a change of holder, provide identification, the property address, the meter number or reading, the date of occupation and bank details. Owners may need proof of ownership, while tenants usually provide their rental contract and may need the landlord’s authorisation. Water bills can include supply, wastewater and other municipal charges, and they are often issued less frequently than electricity bills.
If you notice a suspected leak, close the internal stopcock if safe and contact the building administrator or water service promptly. A sudden increase in consumption should be reported with photographs and meter readings. For problems inside the building, the responsibility may belong to the owner or community of owners rather than the public network.
Choosing home internet
Broadband availability is address-specific, especially in older buildings and central streets. Check fibre availability using the complete address, including staircase, floor and door. Providers such as Movistar, Orange, Vodafone and Digi operate in parts of San Sebastián, but coverage, installation dates and available speeds vary by building. Comparing current offers is essential because promotions and conditions change.
Ask whether installation, the router, line activation and any technician visit are included. Confirm the minimum commitment period, early cancellation charge, price after the promotion and whether a mobile line or television service is bundled. If you work from home, check the upload speed and whether the provider offers a backup option. A 4G or 5G router can be a temporary solution while fixed fibre is being installed, subject to mobile coverage at the address.
Useful timing and troubleshooting tips
- Start electricity and water account changes before moving day, particularly during summer and at the end of the month.
- Keep contract numbers, confirmation emails, meter photographs and payment receipts together.
- For a power cut, check whether neighbours are affected and contact the distributor shown on your electricity bill rather than only the retailer.
- For internet faults, use the provider’s technical-support number and request a reference for every report.
- Use 112 only for genuine emergencies, such as fire, serious injury or immediate danger.
Once the services are active, update your correspondence address and arrange final meter readings when leaving. For help comparing providers or finding local installation and maintenance services, browse local businesses in the directory.
