GermanyMust the Landlord Use the Cheapest Utility Provider?
No — German law requires landlords to act economically, but not to select the absolute cheapest provider. Prices must be objectively reasonable, not necessarily the lowest available.
What the Law Says
German law does not require landlords to obtain multiple quotes or choose the cheapest service provider for operating costs — but it does impose a duty of economic efficiency when managing and billing those costs.
Under § 556 of the German Civil Code (BGB), operating costs ('Betriebskosten') are recurring expenses arising from ownership or proper use of the building and property — such as heating, water, waste disposal, cleaning, and building insurance. Tenants may be contractually required to reimburse these costs, usually via monthly advance payments.
Crucially, § 556(3) mandates that annual operating cost statements must comply with the 'principle of economic efficiency' ('Grundsatz der Wirtschaftlichkeit'). This means the landlord must avoid unnecessary or excessive expenditures — but it does not oblige them to shop around or select the lowest-priced vendor. What matters is whether the chosen price is objectively reasonable in light of market conditions, service quality, and long-term value.
The law also sets strict deadlines: the landlord must send the annual statement to the tenant no later than 12 months after the end of the accounting period. If they miss this deadline, they lose the right to charge any shortfall — unless the delay was not their fault.
Statutory TextÜber die Vorauszahlungen für Betriebskosten ist jährlich abzurechnen; dabei ist der Grundsatz der Wirtschaftlichkeit zu beachten. Die Abrechnung ist dem Mieter spätestens bis zum Ablauf des zwölften Monats nach Ende des Abrechnungszeitraums mitzuteilen. Nach Ablauf dieser Frist ist die Geltendmachung einer Nachforderung durch den Vermieter ausgeschlossen, es sei denn, der Vermieter hat die verspätete Geltendmachung nicht zu vertreten.

What Courts Have Said
Germany’s highest civil court has clarified how the 'principle of economic efficiency' applies in practice — emphasizing substance over procedure.
The court ruled that the 12-month objection period under § 556(3) applies not only to formal errors but also to challenges based on uneconomical spending. It confirmed that economic efficiency does not require obtaining competing quotes — instead, courts assess whether the charged amounts are objectively excessive compared to market standards, considering factors like service scope, contract duration, and reliability.
What to Do
Review your annual operating cost statement carefully — check whether charges align with actual services rendered and appear reasonably priced for your area and building type.
If you suspect uneconomical costs (e.g., unusually high cleaning or maintenance fees), gather local market comparisons (e.g., quotes from other providers or industry benchmarks) before raising objections.
File any written objection within 12 months of receiving the statement — delays may waive your right to challenge even substantively unjustified costs.
Keep records of all communications and statements; if dispute escalates, consider seeking advice from a tenants’ association ('Mieterverein') or legal counsel.
