Hot water allowance wrongly calculated by the Jobcenter — how to check your decision

Anyone who heats their own hot water — with an instantaneous water heater (Durchlauferhitzer), boiler or electric under-sink device — does not get these costs reimbursed through the heating-costs statement. Instead, you receive a monthly additional need (Mehrbedarf). This is exactly where Jobcenters miscalculate noticeably often: wrong percentages, forgotten items, capped amounts. It is worth running the decision through your calculator.

The most important points in 30 seconds

• Anyone who heats their hot water decentrally (instantaneous heater, boiler) is entitled to an additional need (Mehrbedarf) under § 21 Abs. 7 SGB II.
• The allowance is a fixed percentage of the applicable standard need (Regelbedarf) — 2.3 % for adults, less for children.
• Typical errors: wrong percentage, allowance completely forgotten, capping at a fictional consumption, additional need granted for only one person despite a benefit community (Bedarfsgemeinschaft).
• With central hot water supply (hot water via the ancillary-costs bill) there is no allowance — this is part of housing costs (Kosten der Unterkunft, KdU).
• Against a faulty decision you have one month to file an objection (Widerspruch) (§ 84 SGG).

Why the Jobcenter gets this wrong so often

The allowance for decentralised hot water provision (Warmwasserpauschale) is a small but permanent item. It is paid automatically each month — or not. And because the percentages are different for every family member, something regularly slips through the cracks. Sometimes the additional need is only accounted for the "main applicant", sometimes it is capped at a flat rate, sometimes it is missing altogether.

The background: since 2011, the cost of hot water is no longer covered through the standard need (Regelbedarf) but calculated separately. The legislator wanted to do justice to the fact that households with an instantaneous heater actually use more electricity than households with central supply. Because the real costs are hard to determine, fixed percentages were set, derived from the respective Regelbedarf.

A concrete calculation example: Frau Z. lives alone, has an instantaneous heater in the bathroom and an electric under-sink boiler in the kitchen. Her Regelbedarf as a single person is 563 € (as of 2025). The additional need works out like this: 2.3 % × 563 € = 12.95 € per month. The Jobcenter had entered only 8.50 € in her decision — a difference of 4.45 € per month, or 53.40 € across a year. Sounds small, but it runs quietly in the background, month after month.

A second example: Familie W. — two adults and two children (aged 8 and 12) — lives in a flat with an instantaneous water heater. The additional need is calculated like this: 2 × 2.3 % × 506 € (Regelbedarf for partners in a Bedarfsgemeinschaft, RS2) = 23.28 €, plus 2 × 1.2 % × 390 € (Regelbedarf for children aged 6–13, RS5) = 9.36 €. Together: 32.64 € per month. The decision contained only an amount for the parents — the children had been forgotten.

Your rights in concrete terms

1. Entitlement to the additional need (§ 21 Abs. 7 SGB II). As soon as your flat is supplied decentrally with hot water, you are entitled to the allowance — and that applies to every member of the benefit community (Bedarfsgemeinschaft). In the Bedarfsgemeinschaft (all persons in the household whose income is counted together), each person receives their own percentage on their own Regelbedarf.

2. The correct percentages (as of 2025, § 21 Abs. 7 SGB II):

   • 2.3 % for adults (Regelbedarfsstufe 1 — single persons, 563 €)
   • 2.3 % for partners in a Bedarfsgemeinschaft (Regelbedarfsstufe 2, 506 €)
   • 2.3 % for adults under 25 living with parents (Regelbedarfsstufe 3, 451 €)
   • 1.4 % for adolescents aged 14 to 17 (Regelbedarfsstufe 4, 471 €)
   • 1.2 % for children aged 6 to 13 (Regelbedarfsstufe 5, 390 €)
   • 0.8 % for children aged 0 to 5 (Regelbedarfsstufe 6, 357 €)

3. Entitlement to the actual costs if they are higher (§ 21 Abs. 7 Satz 2 SGB II). The allowance is only the default. If you prove through invoices that your real hot-water costs are higher, the Jobcenter must cover the actual need. The Jobcenter may not use the allowance as a cap.

4. No deduction with central hot water supply. If your hot water is generated centrally (via the heating system of the building, billed through ancillary costs), this belongs to the housing costs (Kosten der Unterkunft, KdU) under § 22 SGB II. An allowance under § 21 Abs. 7 SGB II is then not permissible — neither as a top-up nor as a deduction.

5. Right of objection (Widerspruch, § 84 SGG). Against any decision in which the allowance is missing or wrongly calculated, you can file an objection within one month. If the deadline has already passed, a review application under § 44 SGB X (Überprüfungsantrag) often helps: this lets you obtain back payments for up to one year retroactively.

Current case law

The basic structure of the additional need has been legally clear since the 2011 reform. Case law mainly develops at three points.

First: Capping the allowance in the face of proven higher costs. The Federal Social Court (Bundessozialgericht, BSG) has clarified that the flat amount under § 21 Abs. 7 Satz 2 SGB II is only the rule, not the upper limit. Anyone who provably consumes more — for example, because of particularly old, inefficient appliances or a large number of people relative to the flat size — gets the actual costs reimbursed ([URTEIL-REFERENZ]).

Second: Distinction between central and decentralised. If the hot water is produced via the heating system, it belongs in the ancillary-costs statement and thus in the KdU under § 22 SGB II. The additional need under § 21 Abs. 7 SGB II is not applicable in that case. State Social Courts (Landessozialgerichte) have stressed in several proceedings that what counts is the actual type of supply, not the designation in the tenancy contract ([URTEIL-REFERENZ]).

Third: Mixed forms. If a flat has partly central, partly decentralised heating (e.g. central heating but an under-sink boiler in the kitchen), there are diverging rulings. The prevailing case law also recognises a proportional additional need here if the decentralised generation plays a significant role ([URTEIL-REFERENZ]).

How to proceed now

1. Establish how your hot water is generated. Check your bathroom and kitchen. An instantaneous heater (Durchlauferhitzer) is usually a small white or silver device above the sink or in the bathroom, often with a toggle switch. A boiler is a round or square tank, sometimes under the sink ("Untertisch"). Anything that runs on electricity or gas inside your flat is decentralised.

2. Pull the decision out of the drawer. Look in the approval notice for the item "Mehrbedarf für Warmwasser", "dezentrale Warmwassererzeugung" or "§ 21 Abs. 7 SGB II". Sometimes it appears under the benefits per person, sometimes as a total.

3. Recalculate using the correct percentages. For every person in your Bedarfsgemeinschaft, take the applicable Regelbedarf and multiply by the correct percentage. The total must appear in the decision.

4. Cross-check actual costs. Is your electricity consumption for hot water clearly above the allowance (e.g. with an old instantaneous heater and a large family)? Then collect annual bills and invoices. You can demand the higher amount.

5. File an objection (Widerspruch). In writing, within one month after the decision was delivered. A single sentence suffices at first: "Hereby I file an objection against the decision of … . Reasons will follow." You submit the calculation with the reasoning.

6. Submit a review application for older decisions. If you notice that the allowance has been wrong for a long time: an informal application under § 44 SGB X, retroactive back payment for up to one year is possible.

Typical mistakes to avoid

• Do not accept a "forgotten" additional need. Particularly in initial decisions, the allowance is often missing completely because the Jobcenter did not ask for it in the application. Actively include it, at the latest in the objection.

• Do not let yourself be confined to a flat rate. If your hot-water electricity is provably more expensive, you are entitled to the real costs. "The allowance is the maximum" is a common but incorrect statement from case workers.

• Do not forget the children. Every child has their own percentage on their own Regelbedarf. If the decision is missing the item for one of your children, the decision is wrong.

• Do not let yourself be charged for central supply. Some Jobcenters wrongly deduct the allowance from the heating-costs statement, although the hot water is already part of the KdU. That would be a double cut and is not permissible.

Frequently asked questions

How do I know whether I have central or decentralised hot water supply?

If there is a dedicated device in your flat that heats water — instantaneous heater, boiler, under-sink device, a gas combi-boiler only for your flat — it is decentralised. If the hot water already arrives through the pipe ready-made and appears on your ancillary-costs bill as "Warmwasser" or "Warmwasserzubereitung", it is central. When in doubt, look at your tenancy contract or briefly ask your landlord.

How much is the allowance in 2025 for a single person?

For a single adult, the additional need is 2.3 % of the Regelbedarf. With a Regelbedarf of 563 €, that is 12.95 € per month. For a couple in a Bedarfsgemeinschaft, 2.3 % of the Regelbedarf of 506 € applies per partner, i.e. 11.64 € per person — together about 23.28 € per month.

What do I do if the allowance has been wrongly calculated for years?

File a review application under § 44 SGB X (Überprüfungsantrag). This lets you have final decisions corrected retroactively. Back payments are possible up to one year back. The application is informal; a letter to the Jobcenter is enough — asking for review and recalculation of the hot water allowance (Warmwasserpauschale) since the first faulty decision.

Do I also get the allowance if I heat hot water with gas instead of electricity?

Yes. § 21 Abs. 7 SGB II does not distinguish between energy sources. What matters is that generation takes place decentrally in your flat. A gas combi-boiler that supplies only your flat triggers the additional need just as an electric instantaneous heater does.

Do I have to submit my electricity bill to get the allowance?

Not for the allowance. It is automatically due as soon as decentralised generation is established. Only if you want more than the allowance because your real costs are higher, do you have to produce invoices and consumption statements.

Have your decision reviewed now

The hot water allowance (Warmwasserpauschale) is small, but it runs month after month. Anyone who gets 4 € or 10 € too little here loses three-digit amounts over the years — without noticing. A brief look at the decision is often enough to spot errors.
