Compare electricity prices in Spain: save on your bills

How to use our energy comparator

Finding the cheapest electricity or gas tariff in Spain is simpler than it seems. Our comparator is designed so that any resident can use it without complications, in just a few steps and with no need to be an expert in the Spanish energy market.

• Choose your supply: select whether you want to compare electricity, gas or both.
• Enter your details: tell us your average consumption and your contracted power (Standing Charge). If you do not have these figures to hand, we use default values based on average profiles: for electricity, different proportions of consumption across peak, off-peak and flat-rate hours; for gas, 200 kWh/month if you only use gas for cooking and hot water (RL.1), or variable consumption depending on the time of year if you have central heating (RL.2).
• Personalised results: filter by the cheapest tariffs or those rated highest by our experts.
• Free advice in English: once you have made your choice, a specialist adviser will guide you through the sign-up process free of charge and help you prepare the necessary documentation.

To take out any supply contract in Spain you will need: a valid NIE or passport and the CUPS number for your property (you will find it on any previous bill or you can ask your landlord).

To offer you real savings, we need to understand how you use energy at home. Our interactive process will help you find the best option in under two minutes.

How does our personalised comparison work?

When you start the process, our assistant will guide you through a series of key questions designed to ensure that the savings we show you are real and applicable to your situation. Here are some of the things we will look at together:

• Your switching history: we will ask, for example, when you last changed supplier. This is important because in Spain discounts typically expire after 12 months, meaning you could be paying more than necessary without realising it.
• Your preferences: we will ask a few straightforward questions, what type of tariff you are looking for, when you last switched supplier and whether you have a bill to hand, so we can tailor the results to your actual situation.
• The accuracy of your data: do you have a bill available? If so, we can calculate your potential savings to the last cent. If not, we will help you estimate your consumption step by step, based on the size of your home and the number of people in your household.

What should you look for when comparing electricity tariffs in Spain?

Choosing a tariff in a liberalised market can seem daunting. Here are the five key aspects to bear in mind:

• The standing charge (potencia): this is the fixed cost you pay for your contracted power capacity, regardless of how much electricity you use. It is especially important to get this right for holiday homes or properties that will be empty for extended periods.
• The unit rate (término variable): this is the price you pay for each kWh you consume. Entering your actual consumption into the comparator makes the difference between a rough estimate and a precise calculation. View our full pricing methodology.
• Time-of-use periods: in Spain, electricity prices vary depending on the time of day (Peak, Standard and Off-peak). Consider whether your daily routine allows you to take advantage of cheaper hours or whether a flat-rate tariff would suit you better.
• Discounts and contract terms: some offers include introductory prices that expire after six or twelve months. Always check whether the price remains stable after the initial period or rises sharply.
• Customer service: a key factor, particularly if Spanish is not your first language. Check whether the supplier offers support and contracts in English.

Gas tariff comparator and dual deals (electricity + gas)

In Spain, your gas access tariff (RL.1, RL.2 or RL.3) is assigned based on your annual consumption. Knowing which band you fall into is key to ensuring the comparator shows you accurate prices that match your situation.

How does our personalised gas comparison work?

Just as with electricity, our assistant will ask you a series of targeted questions to filter the offers that genuinely suit you. Here are some of the things we will go through together:

• Your home setup: we will ask what you use gas for, cooking, hot water or central heating. With that information, we find the offers that truly fit your home.
• Seasonal consumption: gas usage can vary significantly throughout the year. If you have a bill to hand, the results will be highly accurate. If not, our system will calculate using average values.

What should you look for when comparing gas tariffs in Spain?

The gas market can seem complex due to the different access tariffs and technical concepts involved. Here are the five key factors to consider:

• Your estimated annual consumption: in Spain, your gas tariff (RL.1, RL.2 or RL.3) is assigned automatically based on how much you consume per year. If you only use gas for cooking and hot water, your profile will differ from that of a home with gas central heating. The comparator adjusts prices according to your profile so there are no surprises.
• The monthly standing charge: just as with electricity, gas has a fixed charge you pay every month simply for having access to the supply. If you have a holiday home that will be empty for long periods, it is worth looking for a tariff with the lowest possible standing charge.
• The unit rate (variable term): this is the price you pay for each kWh of gas you consume. The higher your consumption, the greater the impact this figure has on your final bill.
• Maintenance services: many suppliers offer attractive discounts if you take out their boiler maintenance service. Before agreeing, check whether you already have this covered under your home insurance and whether the monthly cost is worth it compared to the discount on offer.
• Offer duration and contract terms: introductory prices that expire after six or twelve months are very common. At Selectra, we help you identify how long your savings will last and whether you are free to switch supplier if you find a better deal later on.
