Spain's TUR tariff and the electricity bill trick that inflates your bill

From an estimated 698 kWh to an actual 2,175: how the electricity bill spirals out of control

A €271 bill for a 60-square-metre flat with two occupants. That is the starting point: 1,691 kWh in a month with two electric radiators programmed at 19-20 degrees, energy-saving light bulbs and class A appliances. The meter, however, held a worse surprise: the previous reading had been estimated at 698 kWh, and the real one jumped to 2,175. The next bill, with the meter already at 2,730, pointed to another rip-off. The question that opens this issue is not how to save a little, but how much of that bill reflects actual consumption and how much reflects a billing system that works against the customer.

How much an all-electric home really uses

The figures reported by different households serve as a yardstick. A 90-square-metre home with five people and all-electric appliances runs between **600 and 700 kWh a month**, according to one forum user. Another, with two freezers, a fridge, a washer-dryer, an induction hob, an oven, a water heater and two computers switched on almost all the time, comes to around **500 kWh a month**, and that without electric heating, according to another. With radiators, last winter one case similar to the initial bill reached **1,200 kWh**, according to the same forum user.

The jump to 2,175 kWh is only explained by three culprits: **electric radiators**, the **water heater** and the **induction hob or oven**, if present. In the case of the initial bill there was no hob or oven, so heating and hot water take the blame. A fact worth remembering: a 1,500 W radiator and a 750 W one switched on intermittently during a cold month add up to hundreds of kWh without the thermostat dropping below 19 degrees.

The estimated reading, the hole nobody looks at

The bill does not always reflect what you consume. When the company does not read the meter, it **estimates** and bills based on that estimate. If the estimate falls short, the adjustment comes later, all at once, with the real reading. In the case that opens this discussion, the difference between the estimated and actual reading was **1,477 kWh in a single bill**. This mechanism explains why one month seems cheap and the next wrecks the household budget.

There is a check that costs nothing and almost nobody does: look at the meter and compare it with what the bill says. If the numbers don't add up, a complaint is worth pursuing. And if the meter over-reads due to a technical fault, the company refunds the overcharge, although verification can cost **more than a hundred euros** if the error is not proven, according to one forum user.

Which tariff is best and how they switch it without telling you

The last-resort tariff, the **TUR** (Spain's regulated electricity tariff), is the regulated option and the cheapest for most households, according to several forum users. Within it, the **time-of-use** variant shifts consumption to cheaper hours: at night and much of the morning in winter, somewhat later in summer. The savings depend on discipline: whoever concentrates the washing machine, dishwasher and water heater in off-peak hours can keep expensive consumption to a third of the total, according to one forum user's calculation.

The problem arises when you ask for one thing and are signed up for another. At a commercial office, the switch to the TUR with time-of-use pricing was requested, but a deregulated-market night tariff with a friendly name was applied instead: **one cent more per kWh in off-peak hours and four cents more in peak hours** than the TUR with time-of-use, according to one forum user's complaint. The complaint is repeated: retailers offer the TUR on their websites in dribs and drabs and push customers to the deregulated market as soon as they ask for a change, according to another.

The price of the kWh that never stops moving

Bills from these months show a price per kilowatt hour that fluctuates more than a commodity quote. **0.142349 euros** in March and **0.168075 euros** in May have been seen, with regularisations and estimated readings mixed into the same bill, according to the bills provided by one forum user. That volatility makes it impossible to compare two bills without breaking down days, time bands and contracted capacity.

In this landscape, contracted capacity also matters. Having **5.75 kW** could leave customers outside the TUR if plans to force millions of users with that capacity out of it are confirmed. The threat, aired in the financial press, adds a layer of uncertainty to any savings calculation.

Heating water: the microwave beats the kettle

Among the small consumption items that add up, hot water for tea has its own logic. An electric kettle seems efficient, but if you already have gas at home, the gas bottle wins on cost, according to one forum user. And when it comes to heating a single cup, the **microwave** is more efficient than the kettle because of its estimulante ilegal, although gas remains the cheapest for cooking, according to the same forum user. Details like this, multiplied by three times a day, are what separate a contained bill from one that hurts.

---

The map of household savings is clear: read the meter, keep an eye on estimated readings, request the TUR with time-of-use pricing in writing and distrust tariffs with commercial names. What remains unresolved is how much of the bill reflects actual consumption and how much reflects a system that bills blind and corrects when you have already paid.
