Fixed price with no surprises and without permanence.
Your bill has two main components:
There are easy “amateur” ways of working it out: if your circuit breaker never trips, it’s likely you have some margin to reduce service capacity. However, you’re already at the limit if it frequently trips.
Whatever the case, changing service capacity is not a decision you can take lightly. It’s better to forget about doing it yourself, and leave it to the professionals. We recommend you ask an approved installer to take a look at your set-up.
Endesa can help if you have any questions (after opening the contact form, select “Consultation", the category "Advice" and the subject "Doubts about the service capacity I need").
Unnecessarily higher bills.
Interruptions in supply, which will mean you have to increase the service capacity again (at an extra cost).

The distributor is responsible for supplying energy to your home. You can’t choose distributors because they are assigned by area. Your distributor may charge you for making changes to service capacity. Details of which distributor covers each area are provided here:
Your distributor will charge you:
Be careful! Sometimes what appears to be cheap at first ends up costing a lot. If you reduce service capacity by too much, you might not have enough (your circuit breaker may trip when you turn on several appliances at the same time). You’ll have to increase it again and will pay quite a bit more than you had expected. Distributors are also only obliged to alter your service capacity once a year, so you may encounter problems if you need to make more changes.
You may also have to pay for a new Electrical Installation Certificate on top of all these charges (which costs 50-200 euros).
It’s a document that certifies your supply is in working order. In this section, we explain why the Electrical Installation Certificate (CIE) is so important.
Your distributor requires one in the following circumstances:
You’ll need to call an approved technician to get a new certificate: charges vary a lot (50-200 euros), so we recommend asking for several quotes. If you live in Catalonia, these charges are higher if you request another type of certificate (Blue Certificate or BRIE - Electric Recognition Bulletin -).
Once you have a certificate, please send it to us at the following email address: firstname.lastname@example.org (you have 30 days to send us the certificate after applying for your service capacity to be changed).
Decreasing your service capacity will have an immediate effect on your bill, and will continue to do so because it means reducing a fixed charge.
For an average home, you’ll save around 5 euros a month or 60 euros per annum for each service capacity band you drop down to.
