Alquiler de contador: qué es y cuándo se paga (Forensic Guide)

⚡

Respuesta rápida

Meter rental is a mandatory monthly fee paid to the electricity distributor for the use and maintenance of the power meter. In Spain, most consumers pay this regulated cost as part of their electricity bill instead of owning the device. The amount is fixed by the government and varies depending on the type of installation.

What is 'alquiler de contador' and when is it paid?

The meter rental is a regulated cost for the hardware that measures your consumption. Unless you own the meter, this fee is mandatory.

The definition in one sentence

It is the daily rent for the meter owned by the distributor, regulated by the government.

Where it appears on the bill

Usually in the 'Other concepts' or 'Detail' section of your PDF invoice.

Why it matters: Money and traps

It's a small fee but a common place for 'vampire' costs that drain your bank account.

The most common error

Ignoring extra services bundled with the rental that double your fixed costs.

The forensic clue

Check the daily rate; it should be around 3 cents for most domestic contracts.

How to check it in 60 seconds

A quick scan of your PDF can save you money without needing to call anyone.

What to search for

Search for 'medida' or 'alquiler' in your digital bill.

The Case of the Silent Vampire

A retired homeowner who avoids sales calls noticed his monthly bill was creeping up. He assumed it was the price of light, but a forensic audit revealed he was paying for a 'Premium Protection' service hidden right next to his meter rental. He hadn't noticed because the line item looked official and was only a few euros, but it added up significantly over the year.

Hallazgos

✓Contracted power was 4.6 kW while his actual peaks never exceeded 2.8 kW.
✓A hidden maintenance fee of €6.99/month was bundled with the meter rental.
✓His effective price was €0.23/kWh, significantly higher than market alternatives.
