Setting up utilities in Madrid: water, gas, and electricity

Understanding utilities in Spain

When you rent a flat in Spain, the utilities are rarely included in the rent. You will be responsible for el agua (water), la luz (electricity), and often el gas (gas/heating). The landlord usually leaves the utilities connected, but it is your legal and financial responsibility to change the contracts into your name (cambio de titularidad).

Do not rely on simply paying the landlord back every month. If they stop paying the bill, the provider will shut off your electricity, and reconnecting it is expensive and requires a new safety certificate (boletín eléctrico).

Step 1: Electricity (La Luz)

Spain's electricity market is divided into two parts: the distributor (distribuidora), who owns the cables, and the marketer (comercializadora), who sends you the bill.

1. Find the current bill from the landlord.
2. Note the CUPS number (Código Universal de Punto de Suministro). This is a 20-character ID for your meter starting with "ES".
3. Check the contracted power (potencia contratada). This dictates how many appliances you can run simultaneously before the breakers trip. For an average flat, 3.45 kW or 4.6 kW is standard. Do not increase it unless necessary, as you pay a fixed monthly fee based on this number.
4. Call your chosen provider (Endesa, Iberdrola, Naturgy, or smaller ones like Holaluz or Lucera) to request the name change. You can stay with the landlord's provider or switch.

Free market vs. Regulated market (PVPC)

You must choose a tariff:

• Regulated (PVPC): The price changes every hour based on wholesale market demand. It is historically cheaper but volatile.
• Free market (Mercado libre): You agree on a fixed price per kWh with the provider, offering stability but often at a premium.

Step 2: Water (El Agua)

Water in the Community of Madrid is managed by a single public company: Canal de Isabel II. You cannot choose your provider.

1. Locate the Número de Contrato (contract number) on the landlord's old water bill.
2. Go to the Canal de Isabel II Virtual Office or call their customer service.
3. Request a cambio de titularidad.
4. You will need your NIE/Passport, a copy of the signed rental contract, and a Spanish IBAN for the direct debit.

Step 3: Gas

Many Madrid flats use natural gas for heating (calefacción) and hot water.

1. Like electricity, find the CUPS number on an old gas bill.
2. The process is identical to setting up electricity: call the provider, request a name change, and provide your bank details.
3. Keep an eye out for mandatory annual gas inspections. The cost is usually added to your monthly bill, but scammers sometimes pose as inspectors demanding cash at your door. Never pay cash to an inspector.

Red flags

• Door-to-door salesmen: Ignore salespeople who knock on your door claiming to be from your electricity company. They are usually third-party marketers trying to switch you to an expensive contract on the spot.
• Missing boletín: If the electricity was disconnected entirely, you must pay an electrician to issue a new Boletín Eléctrico (Certificate of Electrical Installation) before a provider will reconnect you. This costs around 100-200€.
• Estimated readings (Lectura estimada): Modern flats have smart meters (contadores inteligentes), but older buildings might require you to read the meter yourself and submit it via the provider's app. If you don't, they will estimate your usage and overcharge you.

5-day setup plan

1. Day 1: Obtain the most recent electricity, water, and gas bills from your landlord upon signing the lease.
2. Day 2: Call Canal de Isabel II to complete the water name change.
3. Day 3: Call your chosen electricity provider and initiate the transfer using the CUPS number.
4. Day 4: Contact the gas provider, if applicable.
5. Day 5: Confirm that direct debits (domiciliaciones) are active in your Spanish bank account.
