Electricity bill explained — what every line item means in 2026 (UK + EU)

An electricity bill anywhere in Europe has the same four building blocks: unit rate (price per kWh you used), standing charge (fixed daily fee for being connected), network and policy costs (grid + renewables levies), and taxes (VAT and energy tax). What changes between countries is the size of each block, not the structure.

This guide walks through every line on a typical 2026 bill, explains what each charge actually pays for, and compares sample monthly bills across the UK, Germany, France, Spain and the Netherlands so you can spot why your bill is what it is.

The four building blocks

1. Unit rate (also called "energy rate" or "kWh rate")

This is the price you pay for the electricity itself. It's quoted per kilowatt-hour — typically £0.20–£0.32 in the UK, €0.30–€0.40 in Germany, €0.20–€0.25 in France, €0.18–€0.30 in Spain and the Netherlands for households in 2026.

The unit rate has three layers underneath it:

• Wholesale — what your supplier paid for the electricity on the day-ahead market. Usually 30–50% of the unit rate.
• Supplier margin — their profit and operating cost, typically 5–15%.
• Hedging risk premium — built in if you're on a fixed-rate tariff.

2. Standing charge (or "service charge", "fixed fee", "daily charge")

A flat daily fee for being connected to the grid, charged regardless of how much electricity you use. Covers metering, billing and a share of network maintenance.

• UK: 45–62p/day in 2026 (around £165–£225 per year just to be connected)
• Germany: roughly €5–€15/month (Grundpreis)
• France: €12–€16/month (abonnement, depends on contract amperage)
• Spain: €6–€12/month (potencia contratada)
• Netherlands: €15–€22/month (vastrecht + capaciteitstarief)

The standing charge is why even an empty holiday home gets a bill. In the UK it's been the political flashpoint of the last three years — Ofgem reviewed it in 2024 and kept it largely as is, saying the network must be paid for somehow.

3. Network and policy costs

Most countries roll these into the unit rate, but a few break them out separately. They cover:

• Transmission (the high-voltage TSO grid — National Grid in the UK, TenneT in Germany/Netherlands, RTE in France, REE in Spain)
• Distribution (the low-voltage DNO network bringing power to your meter)
• Renewables levies (UK CFD scheme, Germany's old EEG umlage — phased out 2022, France's CSPE, Spain's prima)
• Capacity payments (paying gas plants to stay online for backup)

These together make up 20–35% of a typical EU bill.

4. Taxes

Two layers in most countries: a per-kWh energy tax (Germany's Stromsteuer at €0.0205/kWh, France's TICFE at €0.0225/kWh) and VAT applied to the total.

VAT rates on electricity 2026:

• UK: 5% (reduced rate for domestic energy)
• Germany: 19%
• France: 20% on the full bill (was 5.5% on subscription, now harmonised at 20%)
• Italy: 10%
• Spain: 21%
• Netherlands: 21%
• Norway: 25%

Sample bills compared — 5,000 kWh/year, April 2026

Same household consumption — 5,000 kWh — gives a 70% spread between the cheapest country (Spain) and the most expensive (Germany). That gap is almost entirely tax + grid fees, not the wholesale price.

How wholesale prices feed your bill

Every weekday around midday CEST, the day-ahead auction publishes 24 hourly prices for the next day. Your supplier either:

• Passes them through to you (smart-hour or "agile" tariffs — your unit rate changes every hour) — this is what Octopus Agile in the UK, Tibber in Norway/Sweden/Germany and aWattar in Austria do.
• Hedges them with forward contracts and offers you a flat rate for 6–24 months. That's the standard "fixed-rate" tariff.

Either way, the wholesale price is the foundation. You can see today's day-ahead prices for every EU country on euenergy's homepage, broken into hourly intervals — so you know exactly what wholesale rate fed into your variable bill, or what your fixed-rate supplier is hedging against.

Reading your meter readings

Every bill compares "current reading" to "previous reading" and multiplies the difference by your unit rate. Three things to verify:

• The "current reading" matches what your meter actually shows (write it down once a month).
• Day/night readings (Economy 7, HT/NT, heures pleines/creuses) are charged at the right rates — many bills get these reversed.
• Estimated bills (marked with "E" or "estimated") aren't compounded for too many months in a row — submit your own reading at least quarterly.

Why your bill changes between months

Three drivers:

1. Consumption — winter heating + lighting is 2–3× a summer month for most homes.
2. Wholesale price changes — if you're on a variable tariff, even constant consumption produces fluctuating bills.
3. Annual policy reset — many countries adjust grid fees + renewables levies every January or April. UK Ofgem caps reset every three months.

FAQ

What does kWh mean on my bill?

Kilowatt-hour — the unit of energy you're charged for. 1 kWh runs a 1,000-watt heater for one hour. See our MWh-to-kWh converter for the wholesale-market unit equivalent.

Why is my standing charge so high?

It pays for grid maintenance, metering and supplier billing — costs that exist whether you use any electricity or not. The UK has the highest in Europe at around 45–62p/day; reform has been politically discussed since 2023 but no major change has landed.

How is my electricity bill calculated?

(Standing charge × days in period) + (units used × unit rate) + (energy tax) + VAT on the total. That's it. Anything more complex (Economy 7, time-of-use, capacity charges) splits the unit rate into bands but the formula is the same.

Why do bills differ between suppliers in the same country?

Suppliers compete on margin and on hedging strategy. Two companies buying the same wholesale electricity can end up with 5–10% different unit rates because one locked in 12-month forward contracts and the other tracks spot. The standing charge and tax are essentially fixed.
