How to read your electricity bill and find what you really pay per kWh

Your real price per kWh is the total of the bill divided by the kWh you used in the period it covers. That number is always higher than the energy price printed in your offer, because the bill also charges for carrying the electricity to your home, for system costs set by law, for fixed monthly fees and for taxes. For the typical household ARERA uses as its reference, the regulator’s own figure for October to December 2026 is 43.43 cents per kWh, taxes included, of which the energy itself is about two thirds.

Below, the Italian bill with the regulator’s names, then the UK, Germany, Spain and the US. All figures were checked on 31 October 2026 on the official sources linked.

What are the parts of an Italian electricity bill?

Since 1 July 2025 suppliers use the same layout, set by ARERA in delibera 315/2024 (press release); the press release notes that households still in the regulated Maggior Tutela service are not covered. ARERA’s bill guide lists five parts:

Frontespizio, the front page: amount due, due date, updated annual consumption.
Scontrino dell’energia, the “energy receipt” on page two: the charges, as quantity times price.
Box dell’offerta: your offer code, whether the price is fixed or variable, and whether it is the same at all hours or different by time band.
Elementi informativi essenziali: boxes with readings, consumption, supply details and history.
Elementi di dettaglio: a separate document, reached through the QR code next to the receipt, with every unit price.

The receipt groups the charges into the quota per consumi, which depends on the kWh you used, and the quota fissa, paid even with zero consumption, which on electricity bills includes a quota potenza line charged for each kW of contracted power. Each block is split again into vendita (the seller’s part, set by your contract) and rete e oneri (network and system charges, set by ARERA). Taxes have their own line, “Accise e IVA” (“Totale imposte e IVA” in ARERA’s guide); recalculations, the social bonus and the TV licence appear where they apply.

ARERA’s quarterly price announcements still use the older names for the same money:

ARERA’s name	What it pays for	Who sets it
Spesa per la materia energia	Buying the energy, dispatching and the seller’s commercial costs	Your contract (on the free market)
Spesa per il trasporto e la gestione del contatore	Carrying electricity to your meter and measuring it	ARERA, same across Italy
Spesa per oneri di sistema	General system costs set by law, mainly support for renewables	ARERA; they do not depend on your offer
Imposte	Excise duty (accisa) and VAT (IVA)	The law

The TV licence, listed on the receipt as “Canone di abbonamento alla televisione per uso privato” (canone TV for short), is not an energy charge: the Agenzia delle Entrate says it is 90 euro a year, charged on electricity bills in ten monthly instalments from January to October.

What does a typical bill look like, line by line?

Every quarter ARERA publishes the price for its “cliente tipo”: 2,000 kWh a year, 3 kW of contracted power, in the regulated Maggior Tutela service for vulnerable customers. From 1 October 2026 it is 43.43 cents per kWh, taxes included, 37.3% more than in the previous quarter because wholesale prices rose. The last column applies it to a two-month bill of 333 kWh, one sixth of the year.

Line	Cents per kWh	Share	On a two-month bill (333 kWh)
Materia energia: buying the energy	27.64	63.7%	€92
Materia energia: retail sales costs	2.11	4.9%	€7
Trasporto e gestione del contatore	6.18	14.2%	€21
Oneri di sistema	3.32	7.6%	€11
Imposte (excise and VAT)	4.18	9.6%	€14
Total	43.43	100%	€145

Assumptions: ARERA’s reference household and prices for October to December 2026; consumption spread evenly over the year; rounded to the euro. On the free market the network and system charges are the same, because ARERA sets them; the materia energia depends on the offer.

How do you work out what you really pay per kWh?

Take the Totale bolletta from the receipt. It is the amount for the electricity supply: the canone TV and add-on services come after it, on the way to the Totale da pagare, the amount you actually pay.
Take out what belongs to other periods: the ricalcoli line and any importi relativi a bollette precedenti.
Divide by the kWh billed in the same period, shown on the quota per consumi line.

Example values, to change to yours: a two-month bill with a Totale da pagare of €150, of which €18 is canone TV (two instalments of €9) listed after a Totale bolletta of €132, for 330 kWh. €132 divided by 330 kWh is €0.40 per kWh. If the Box dell’offerta says €0.25 per kWh, the gap is network, system charges, fixed fees and taxes.

The “prezzo medio” on the quota per consumi line is a different number: ARERA’s rules define it as the average of the per-kWh charges only, without fixed fees and taxes.

How much do fixed fees weigh if you use little? In ARERA’s 2026 values for households (spreadsheet, September 2026), a primary residence pays network charges of €23.04 a year plus €23.72 per kW a year: about €94 a year at 3 kW, before taxes and before the seller’s own fixed fee. Spread over 2,700 kWh that is 3.5 cents per kWh; over 1,000 kWh it is 9.4 cents. ARERA’s own price series shows the same effect: for April to June 2026 its 2,700 kWh household paid 28.89 cents per kWh and its 2,000 kWh household 30.24 cents.

Resident or not? The same spreadsheet charges a home that is not the holder’s registered residence (residenza anagrafica) a further €95.09 a year of fixed system charges, which a residence does not pay. A second home with 3 kW using 1,000 kWh a year thus pays about 19 cents per kWh in fixed network and system charges, before taxes, the seller’s own fixed fee and the energy itself. The excise exemption in article 52 of the excise code also applies only to the home of residence with up to 3 kW: it covers the first 150 kWh a month, and is taken back gradually above 150 kWh a month up to 1.5 kW, or above 220 kWh a month between 1.5 and 3 kW.

What do F1, F2 and F3 mean, and where do you see them?

They are the time bands ARERA defines:

Band	Hours
F1	Monday to Friday, 8:00 to 19:00, national holidays excluded
F2	Monday to Friday, 7:00 to 8:00 and 19:00 to 23:00; Saturday, 7:00 to 23:00; national holidays excluded
F3	Monday to Saturday, 0:00 to 7:00 and 23:00 to 24:00; Sundays and national holidays, all day

A “bioraria” price splits F1 from F23, which is F2 and F3 together. The bands change what you pay only if the Box dell’offerta says your price is by band.

With an electronic meter, the smart meter that records consumption at short intervals, the readings and consumption box must show each band separately (article 8.3), and the bill’s history shows the last 18 months, split by band where the data exist (article 8.9). The receipt itself never splits by band, and the unit price for each band is in the Elementi di dettaglio (article 11.4). For a longer view, ARERA’s free Portale Consumi, run by Acquirente Unico, shows up to 36 months of your data, down to 15-minute intervals where the meter data allow, after logging in with SPID.

How can you tell if your bill is too high?

Compare your annual consumption. The front page shows your updated consumption over the last 12 months. ARERA’s reference households use 2,000 and 2,700 kWh a year with 3 kW. They are reference profiles, not limits.
Check whether the readings were real or estimated. ARERA explains that estimated consumption is billed provisionally and recalculated later. A “ricalcolo” line on the receipt means the bill includes earlier periods, which explains a sudden jump.
Check the contracted power. Most Italian homes have 3 kW, and ARERA says each kW costs about 26 euro a year, VAT included. The bill lists your highest monthly power draw over the last 12 months: if it stays well below the limit, a lower one may do. Changing it is a contract change and the supplier may charge a one-off fee.
Check the prices against the Box dell’offerta. With a fixed price, ARERA says the energy price does not change for at least 12 months; a variable price follows the index named in the box.
Compare with other offers on ARERA’s Portale Offerte, which is free, run by Acquirente Unico, and lists all offers on the retail market. The offer code from your Box dell’offerta works there too.

Households with a low ISEE, the official measure of family income and assets, may be entitled to the electricity bonus sociale, applied automatically on the bill.

How do bills work in other countries?

United Kingdom

Bills show a unit rate per kWh and a daily standing charge. Ofgem’s price cap limits both, not the total bill. From 1 October to 31 December 2026 the average cap for Direct Debit in England, Scotland and Wales is 26.32p per kWh and 54.83p a day, with no VAT on electricity until 31 March 2027. At 2,700 kWh a year that is about 34p per kWh all in; at 1,500 kWh, about 40p.

Germany

The bill has an Arbeitspreis in cents per kWh and a Grundpreis per month or year: the yearly cost is the Arbeitspreis times your consumption plus the Grundpreis, as the Bundesnetzagentur explains. Its latest average household price, 40.05 cents per kWh on 1 April 2025, predates the 2026 cut in network charges, just under 2 cents per kWh on average at the 15 largest grid operators. The Verbraucherzentrale’s checklist (14 March 2025) adds that estimated readings must be clearly marked on the bill.

Spain

The regulated price, the PVPC (precio voluntario para el pequeño consumidor), is open to low-voltage supplies up to 10 kW (Real Decreto 216/2014, article 5); its energy price is set hour by hour, from the daily and intraday wholesale markets and partly from a basket of futures contracts (article 6). Household supplies up to 15 kW have a término de potencia, charged on contracted kW, and a término de energía whose regulated charges follow three periods (CNMC Circular 3/2020, article 7; CNMC explainer): on weekdays punta 10:00 to 14:00 and 18:00 to 22:00, llano 8:00 to 10:00, 14:00 to 18:00 and 22:00 to 24:00, valle 0:00 to 8:00; Saturdays, Sundays, 6 January and national holidays are valle all day.

United States

The EIA puts the average residential price at 18.16 cents per kWh in August 2026 (preliminary), from 12.72 in Nevada to 47.18 in Hawaii, and average use at 10,791 kWh a year in 2022. The EIA does not publish rate schedules: your utility’s tariff sheet lists the fixed and per-kWh charges.

Where does this answer stop?

Gas bills, business supplies and homes with solar panels have extra lines not covered here. Regulated prices and network charges change every quarter or year; each figure carries its period.

Common questions

How do I know how much I pay per kWh?

Start from the Totale bolletta on the receipt, which already leaves out the TV licence and add-on services; take out any recalculations and amounts from earlier bills; divide by the kWh billed in the same period. That is your real price per kWh, with network charges, system charges, fixed fees and taxes all included. The energy price written in your offer covers only part of it.

What do F1, F2 and F3 mean on the electricity bill?

They are the time bands ARERA defines. F1 is weekdays from 8:00 to 19:00; F2 is weekdays from 7:00 to 8:00 and from 19:00 to 23:00, plus Saturdays from 7:00 to 23:00; F3 is every night from 23:00 to 7:00 and all of Sundays and national holidays. They change what you pay only if your offer has prices by band.

How can I tell if my electricity bill is too high?

Look at the annual consumption on the front page and compare it with ARERA's reference households of 2,000 and 2,700 kWh a year at 3 kW. Then check whether the readings were real or estimated, whether the bill contains a recalculation of earlier periods, and whether the prices match the offer box. Your own consumption history is on ARERA's free Portale Consumi.

Why does a second home pay more for electricity in Italy?

Because some charges depend on residence. In the values ARERA published for September 2026, a home that is not the holder's registered residence pays about 95 euro a year in fixed system charges that a primary residence does not pay, before taxes. The excise exemption on the first kWh each month also applies only to the home of residence with up to 3 kW.

How much is the electricity bill if I use nothing?

You still pay the fixed fee and the power fee. For a primary residence with 3 kW, ARERA's 2026 network values add up to about 94 euro a year before taxes, plus whatever fixed fee your supplier charges. For a home that is not your residence, add about 95 euro a year of fixed system charges.
