I'd rather you call me

Living in Spain

Spanish bills weren't written with you in mind.

Different vocabulary, different rules, and nobody explains them. These are the three things we fix most often for people who moved here.

Holiday home

Paying for an empty house

The fixed part of the bill, the potencia, is charged every single day, whether anyone is there or not.

  • We check if you are contracted for more power than you use
  • Lowering it is paperwork only: no engineer, no visit
  • The saving repeats on every bill, all year
Just bought

Bills in someone else's name

Many buyers inherit the previous owner's contract, tariff and add-on services without ever choosing them.

  • We move the contract into your name
  • We find extras you never asked for
  • NIE or passport: we tell you exactly what is needed
In English

No Spanish required

You deal with one adviser, in English, by WhatsApp, phone or email. Not a call centre and not a translation app.

  • Your bill explained line by line
  • We handle the supplier for you
  • Based in Torrevieja, on the Costa Blanca

Cómo funciona

Three steps. Only the first is yours.

1

Send us your bill

Leave your name and phone number. It takes less than a minute and we ask for nothing else.

2

Get your review in 24h

We compare tariffs and contracted power, then message you on WhatsApp with your savings explained in plain language.

3

We handle the switch

If you're happy, we take care of all the paperwork. No power cuts and nothing for you to do.

What we check

Four places where your money usually hides.

An electricity bill has more small print than a contract. These are the four points we always check.

Price per kWh

We compare what you actually pay against the best tariffs on the market right now.

Contracted power

Many homes pay for more power than they use. Adjusting it saves money every single month.

Time bands

We look at when you use energy to see whether a time-of-use tariff suits you.

Add-ons and lock-ins

We spot maintenance fees, insurance and lock-in clauses that quietly inflate your bill.

What do you need?

Both options are free. The only difference is how soon you want to move.

Who it's for

If you get a bill, this is for you.

We review electricity and gas supplies across Spain, whatever your contract.

  • Power matched to your real usage
  • Peak, standard and off-peak bands
  • Fixed vs indexed price comparison
Self-employed

Transparency

It's free for you. And we'll explain why.

We earn a commission from the supplier only if you decide to switch. Never from you. That's why we only recommend switching if you truly save.

No cost, no small print

The review and the switch cost you nothing. If there are no savings, we tell you and that's that.

No interruption to supply

Switching supplier is purely administrative. Same installation, same meter.

Your data, protected

We use your bill only for your review, in line with GDPR. You can ask us to delete it at any time.

The difference

Doing it alone or doing it with us.

On your own

  • Comparing dozens of tariffs and small print
  • Guessing how much power you need
  • Calling a call centre and waiting
  • Discovering the lock-in when you try to leave
  • Doing it all again every time prices rise

With Voltaris

  • We calculate your power from real data
  • You always speak to the same person
