“I chose a cheap tariff – and the annual bill was still a shock.” Here is how a German energy contract is built.
Two prices, one bill
Every tariff has a standing charge (Grundpreis) – fixed per month or year – and a unit price (Arbeitspreis) per kilowatt hour. Annual cost = standing charge + unit price × consumption, so compare the total for your consumption. The monthly instalment (Abschlag) is an advance payment; at least once a year (§ 40b EnWG) the annual bill settles actual consumption. It must arrive within six weeks of the billing period; credits must be offset or refunded within two weeks (§ 40c EnWG). An instalment set too low ends in a back payment.
Price guarantees: three kinds
According to the Federal Network Agency (1 April 2025), household electricity splits into about 40 % procurement, sales and margin, 28 % grid and metering charges and 32 % taxes, levies and surcharges; the industry association BDEW puts 2026 at 41/25/34 %. Gas also carries the CO2 price, in 2026 within 55 to 65 € per tonne.
| Guarantee | Covers | Does not cover |
|---|---|---|
| Energy price guarantee | energy share only | grid charges, taxes, levies |
| Limited price guarantee | energy share and usually grid charges | taxes, levies, surcharges |
| Full price guarantee | all components | usually only VAT changes |

Term, renewal and special cancellation
For contracts since March 2022 (§ 309 No. 9 BGB): initial term at most two years; renewal only open-ended with one month’s notice; notice before the end of the initial term at most one month.
On a price increase, household customers must be informed at least one month ahead and may cancel without notice, effective when the increase takes effect (§ 41 (5) EnWG) – even if grid charges or levies are blamed (BGH, VIII ZR 163/16). Only a one-to-one VAT pass-through gives no such right (§ 41 (6) EnWG). The right lapses once the increase applies – open the supplier’s letters.
Bonus traps: a new-customer bonus is usually credited only with the first annual bill; what counts is the price from year two.
Basic supply or special contract
Doing nothing lands you with the basic supplier (Grundversorger) (§ 36 EnWG): cancellable with two weeks’ notice (§ 20 StromGVV), a safe fallback but usually the most expensive tariff – on average 44.93 ct/kWh against 38.20 ct/kWh elsewhere (Federal Network Agency, April 2025). Any other contract is a special contract. If your supplier fails, you fall into replacement supply (§ 38 EnWG) without interruption. Since 6 June 2025 a switch must be completed within 24 hours (§ 20a EnWG). Five myths: fact check on switching.
How to proceed
- From your last bill note consumption, standing charge, unit price, contract end and notice period.
- Read your meter at year end, at every price change and when switching, and report it.
- Compare the total for your consumption, deduct bonuses, look at year two.
- Take increase letters seriously – special cancellation until the effective date.
