Setting Up Utilities in Spain: A Step-by-Step Guide for Renters

Moving into a rental in Spain comes with a pile of admin, and utilities are the part that trips people up because every one has its own provider, its own paperwork and its own quirks. The reassuring bit is that none of it is hard once you know the order. This is the sequence we walk clients through on the Maresme coast and in Barcelona.

Start with the basics: NIE and bank account

Before you can set anything up you need a NIE, the foreigner's identity number, and a Spanish bank account. Utilities are paid by direct debit (domiciliación bancaria) almost without exception, and providers will ask for both the NIE and an account number before they'll even start.

You'll also want your rental contract handy. Most providers ask for it as proof you're entitled to the property, along with the CUPS code for the electricity, which is printed on any existing bill or on the meter itself.

Electricity first, because everything runs on it

Electricity is the one to do first. In Spain you contract two things: the potencia, the amount of power in kilowatts you can draw at once, and the tariff. Get the potencia too low and the breaker trips when the oven and the air conditioning run together.

• Find the CUPS code — a 20-character code starting with 'ES', on the meter or a previous bill.
• Pick a supplier — Endesa, Iberdrola, Naturgy and Repsol are the big four, with smaller players like Holaluz and Octopus Energy often cheaper.
• Contract the potencia — a typical villa might want 6 to 10 kW, a flat 4 to 6 kW.
• Give them the NIE, the bank account and the CUPS, and it's usually switched on within a day or two.

Water is local, and that's the surprise

Water doesn't work like electricity. There's no national market. Each municipality has its own operator, and you deal with whoever runs it where you live. In Barcelona city and much of the metropolitan area that's Aigües de Barcelona; across Maresme it varies town by town, with operators from the Agbar group such as Sorea handling much of the coast.

You usually can't switch water suppliers, so there's nothing to compare. You register the account in your name with the local operator, using your NIE, contract and a meter reading. It's slower than electricity and can take a week or two. Don't assume the water is on just because the electricity is.

Internet, and the mobile that goes with it

Internet in Spain is genuinely fast and, by European standards, cheap. Fibre is available in Barcelona and across the Maresme towns, and the main operators are Movistar, Vodafone, Orange and MásMóvil, with budget brands like Digi and Pepephone riding on the bigger networks.

Installation usually takes from a few days to a couple of weeks, and most operators bundle a mobile line with the fibre. The bundle is often worth taking because the combined price is barely more than the fibre alone. Bring your NIE and bank account, and be ready for a one-year contract on some tariffs.

The admin people forget until it bites

Two things catch renters out. First, empadronamiento — registering your address at the town hall — is separate from utilities, and you'll need it for healthcare, schooling and a lot of paperwork. Second, if your landlord has included bills in the rent, check exactly which ones and up to what cap, so a summer of air conditioning doesn't turn into a surprise.

None of this needs to eat your first week. Do the NIE and bank account early, contract electricity on day one, file the water form, and the rest falls into place while you're unpacking. See our Moving to Barcelona as an expat.
