Overview
- Mayor Dieter Reiter, now chair of Münchner Wohnen’s supervisory board, commissioned the review and apologized to tenants who had been blamed for high consumption.
- Inspectors found that the old one-pipe systems combined with upgraded insulation caused extreme heat losses and made apartment-level consumption allocation unreliable.
- Münchner Wohnen was told to clarify all billing issues, repay wrongly charged amounts quickly and unbureaucratically, and establish a causation-based, legally compliant method.
- In the Hasenbergl buildings on Winterstein- and Fortnerstraße, many tenants had faced back payments of several thousand euros and will now receive reimbursements.
- According to the tenants’ association, the affected buildings will have 2024 and the retroactive 2022–2023 heating costs billed by floor area rather than consumption, with a 15% statutory reduction granted and no back charges for those previously underbilled.
