Endesa Única is much more than a flat-rate tariff:

What exactly is a flat-rate tariff? This is an important question as there are plenty of options in the market that call themselves flat rates but aren't really. They fall short of what a real flat-rate tariff should be. Endesa Única exceeds it.

You pay a stable price every month

You consume what you need

You get money back for being efficient

100% sustainable energy

No minimum duration It depends It depends

You can tailor it to your needs

The price is unique for you and your home

  • Endesa unique has all the advantages of a flat-rate tariff. Your monthly quota remains fixed while you consume all the energy you need. In this section we will explain what we do if you consume too much.
  • Endesa Única goes beyond the flat rate concept, as you get money back if you become more efficient and consume less energy. 
  • Endesa Única is not just a tariff. It is much more than that: It is a service platform where you can take control of your energy and add other features.

"Flat rate" is a term we have become used to when talking about our mobile phone and Internet... and now also for energy. You have to go back to the beginning to understand what a flat rate tariff really is.

Everything began before mobile phones had become smartphones. Flat rate tariffs were a ground-breaking idea then: Talk for as many minutes as you need and at the end of the month pay a fixed quota. Later, this spread to the Internet: Consume all the MB (and then GB) you need without changing the amount on your bill. 

We need to distinguish clearly between true flat rates, false flat rates and other revolutionary options that exceed what has become established.

True flat rates

The original concept as applied to mobile phones and the Internet is still valid: Use whatever you need to and pay a fixed monthly quota. That is how Endesa Única works.

The minutes, GB and kWh you use will be a line with peaks and troughs, but the line showing what you are going to pay at the end of the month stays flat:

A true flat rate:

  • You always pay the same.

Not a true flat rate:

  • Adjustments are always implemented at the end of the year for excess consumption.

This idea obviously predates the term "flat rate". We can find it in open bars and the payments for services such as gyms, where you pay and can use the gym as often as you want.

Endesa Única is a genuine flat rate tariff, as it meets the following key requirement:

  • What you pay does not depend on what you end up using.

This is the case as long as both sides respect some minimum principles of transparency and common sense. It would be unreasonable for anyone to order twenty coca colas in a bar in five minutes or for someone to sleep in the gym.

If you consume too much there will be no surprise bill but we will contact you to recalculate your monthly quota.

False flat rate tariffs

As flat rate tariff sounds attractive, it has been used for tariffs that are not really flat rates. It might seem like they are, because they assure you that what you pay each month never changes... unless you exceed your consumption limit.

Sometimes this is an annual limit. In other words, you pay the same every month, but your consumption is checked at the end of the year and you have to pay more in compensation if you've exceeded your limit. This process is called regularisation. With Endesa Única there is no regularisation

There is nothing wrong with these options. The only problem is that they are being marketed by calling them something they are not. These options are a world away from Endesa Única

If we think about the gym, it would be like them telling you at the end of the year that you have done too many hours of exercise and that you have to pay another 50 euros at Christmas.

There are many examples of false flat rates with electricity and gas tariffs.

It looks like you always pay the same, but at the end of the year it's time to do the sums and see if you have to pay more or get a refund. The threat of a surcharge for excess consumption is always hanging over you. These are not true flat rate tariffs. This is not Endesa Única.

False flat-rate tariffs

Flat-rate tariff is a very attractive term, so it has sometimes been used for rates that are not really flat. It might seem like they are, because they assure you that what you pay each month never changes... unless you exceed your consumption limit.

Sometimes this is an annual limit. This means that: You pay the same every month, but your consumption is verified at the end of the year. If you have exceeded your limit you have to pay an additional amount as compensation.  

These options are absolutely legitimate, the only problem is that they try to call them flat-rate tariffs. Which what they are not.  

If we think about the gym, it would be like them telling you at the end of the year that you have done too many hours of exercise and that you have to pay another 50 euros at Christmas.

There are many examples of false flat rates with electricity and gas tariffs.

It looks like you are going to have a fixed quota, but at the end of the year the time comes to do the sums and see if you have to pay more or get a refund. There is always the threat of a surcharge for excess consumption. These are not true flat-rate tariffs. These are not Endesa Única.

 

Much more than a flat-rate tariff

But why do you keep talking about the concept of an open bar? It is practical and simple, but it's a bit out of date. Endesa Única exceeds it. 

Imagine an open bar where you get back most of what you paid if you drink only half an orange juice, because you have hardly caused any costs.

You have the peace of mind of being able to consume whatever you need, but if you don't some of what you paid is refunded.

Imagine a gym where you get some of your quotas back if you miss a few months.

Imagine this:

  1. Based on the data for your historical consumption, a customised quota is calculated. You do not pay the same as everyone else: You pay a price that is unique for you.
  2. You pay a fixed quota every month. No surprise invoices, just your customised monthly quota for the year your contract lasts. At the end of that year, we review your quota to fit your true needs.
  3. If you meet the energy efficiency challenge and consume less electricity or gas, your bills will include a refund of part of your quota. In other words, if you use less, you pay less.

Do you understand what we are saying? You can stop imagining because this is already the case and it takes less than 5 minutes to contract. It is called Endesa Única and it is much more than a flat-rate tariff. Because, in addition to all that we have told you, it includes:

No minimum duration: If you are not satisfied, you can change your tariff or retailer any time you like, with no penalties.
