Utilities in Spain

Before you compare a single tariff, answer one question: whose name is on the supply right now? Almost every utility problem a new arrival has in Spain traces back to that — an account still in a previous owner's name, a supply that was cut when a property stood empty, a bill the landlord pays and recharges, or a connection that never legally existed.

Tariffs are the easy part, and the part everyone starts with. The contract holder is the hard part, and the part that decides whether you have power on the day you move in.

The question that decides everything

Three situations, and they are genuinely different jobs:

The supply exists and is active, in someone else's name. The normal case when buying or renting an existing property. What you want is a cambio de titular — a change of account holder. It is administrative, it is the cheapest route, and it is what you should insist on rather than accepting "just leave it in my name, I'll forward the bills".

The supply exists but has been cut off. Common with properties that stood empty, were repossessed, or belonged to someone who stopped paying. Reconnection is slower and costs more than a transfer, and it may surface problems — an unpaid balance, or paperwork the property never had.

There is no supply, or no legal connection. New builds, rural properties, anything converted or extended without the right certification. This is a project, not an errand, and it needs someone local who does it professionally.

Why "leave it in my name" is a bad deal, even when kindly meant: the account holder is the person the company deals with. If the bill is wrong, you cannot argue it. If the direct debit fails, you do not hear about it first. If you want to change provider, you cannot. And you are relying on someone else forwarding you a bill accurately and indefinitely.

What each utility actually needs

Each column answers a different question: who you are dealing with, and what they will ask you for.

Table 1

Source: change of supply holder is regulated by Real Decreto 1955/2000; the supply point is identified by its CUPS; the installation certificate is the CIE (boletín eléctrico) issued by an authorised installer. Verified October 2026. No tariff, unit rate or standing charge is published.

The pattern: identity, the property's own reference number, and a Spanish bank account. Assemble those three and every one of these becomes routine.

Electricity: the two things worth understanding

Your supply has a reference number that belongs to the property, not to you. It is called the CUPS — the universal supply-point code — a 20- or 22-character identifier unique to that connection. It appears on any existing bill and it is what every provider asks for first. Get it from the seller, the landlord or the previous bill before you need it; tracking it down afterwards is tedious.

Your contracted capacity is a decision, and it has a standing cost. Spanish electricity contracts specify how much power you can draw at once. Set it too low and the supply trips when the oven and the air-conditioning run together; set it too high and you pay a standing charge for capacity you never use. It can be changed, with a process.

We publish no rates. Spanish electricity pricing has structures that vary by time of day and by tariff type, and the numbers move. Compare on your own current consumption, from an actual bill, rather than on any figure you read in a guide — including this one.

Internet: check the property, not the provider

Spain has extensive fibre coverage, and it is genuinely very good where it exists. What matters is whether it reaches the specific building.

Coverage can differ between one side of a street and the other, and between a village and the urbanización two kilometres outside it. If you work remotely, treat this as a property-selection criterion rather than a post-move errand: check the address with the providers directly, and ask a neighbour what they actually have rather than what is advertised.

If you are renting

Establish, in writing, before signing: which supplies are in the landlord's name and which will be in yours; whether any are included in the rent; and if the landlord pays and recharges, what evidence of the actual bill you will receive.

A landlord who wants to keep everything in their name and recharge you is not necessarily acting badly — it is common, especially for short lets and in communities where water is billed collectively. But it does mean you cannot see, query or change those supplies, and you should know that is the deal you are accepting.
