E.ON District Heating Lawsuit in Germany: What Renters Need to Know
A class-action lawsuit against E.ON over district heating price hikes of hundreds of percent has started in Germany. Here's what it means for expat renters.

If you rent a flat in Berlin — or are trying to find one — you have almost certainly felt the city's brutal housing pressure firsthand. What you may not know is that a landmark democratic vote is hanging unresolved over the entire market, and it is now the defining issue of Berlin's coming September state election. In 2021, more than 56% of Berlin voters backed a referendum to expropriate up to 240,000 apartments from large, for-profit housing companies and transfer them to public ownership. Years later, no action has been taken — and the political battle over what to do next is intensifying. For expats and immigrants who rent privately in Berlin, understanding this debate is essential context for navigating the city's housing market both now and in the years ahead.
The Deutsche Wohnen & Co enteignen (DW Enteignen) initiative gathered enough support to place a question on the Berlin ballot alongside the 2021 state elections: should the city socialise — effectively nationalise — apartments owned by landlords with more than 3,000 units in Berlin?
Voters said yes, with 56.4% in favour. The vote was non-binding in a strict legal sense — it required follow-up legislation from the Berlin Senate to become law. A subsequent expert commission, tasked with assessing legal and financial feasibility, concluded in 2023 that expropriation was in principle legally possible, though it would cost the city between €29 billion and €39 billion in compensation to landlords.
The sheer scale of that cost effectively stalled any legislative action under the previous SPD-led Senate. The current CDU-led Senate, which came to power after a 2023 re-run election, is opposed to expropriation entirely.
Berlin holds state (Abgeordnetenhaus) elections in September, and housing affordability has become the dominant voter concern. The DW Enteignen campaign has successfully kept its referendum result politically alive, demanding the Senate either implement the vote or explicitly reject it with a counter-proposal.
Left-wing parties — including the SPD left wing, Linke, and Grüne — have used the referendum as a rallying point, arguing that the democratic will of the people is being ignored. The CDU and FDP argue that expropriation is financially irresponsible and would not actually add new housing supply, only redistribute existing stock.
The September vote could significantly shift the balance of power in the Berlin Senate and determine whether this referendum ever moves toward implementation — or is definitively buried.
This is the key practical question for expats. Expropriation would transfer ownership of up to 240,000 privately held apartments to a public housing company. Tenants in those apartments would remain in place — their rental contracts would be inherited by the new public owner.
Supporters argue this would create a large, stable pool of affordable, rent-capped housing that would reduce pressure on the wider market and slow overall rent growth. Critics counter that the billions spent on compensation would crowd out investment in new construction, worsening the supply shortage that is the root cause of high rents.
For expats currently in the private rental market — especially those hunting for a new flat — neither outcome guarantees immediate relief. Berlin's fundamental problem is a shortage of housing units, and expropriation does not build a single new apartment.
In practical terms, the referendum has no immediate legal effect on your rental situation today. Your rights as a tenant in Berlin — including protections under the Mietpreisbremse (rent brake) and standard German tenancy law — remain unchanged regardless of the political debate.
However, the election outcome in September will shape Berlin's housing policy for the next five years. If a left-leaning coalition takes power and pushes for implementation, you could eventually see expanded social housing stock and tighter rent controls in the medium term. If the CDU retains power, housing policy is likely to focus on building incentives rather than expropriation.
No. The referendum has not been implemented into law, and even if it were, existing tenants in affected buildings would keep their rental contracts. Your current lease, rent price, and tenant rights remain governed by standard German tenancy law.
Not in the short term. The practical advice remains the same: register on platforms like ImmoScout24, Wohnungsbörse, and WG-Gesucht; prepare all required documents (Schufa, income proof, ID); and consider approaching public housing companies (Wohnungsbaugesellschaften) such as degewo, GEWOBAG, or HOWOGE directly for their waiting lists.
Yes. The Mietpreisbremse (rent brake) currently applies in Berlin and limits how much a landlord can charge for a new rental contract — in most cases, no more than 10% above the local Mietspiegel (rent index) reference price. This applies regardless of who owns the building.
Berlin's housing referendum is a politically charged, legally complex debate that has not yet produced concrete changes for renters. The September election is the next critical moment: watch which parties form a governing coalition and what housing commitments they make. In the meantime, know your tenant rights, use the Mietspiegel as a reference when negotiating rent, and explore public housing waiting lists as a long-term option. For the latest on Berlin housing policy, the tenant association Berliner Mieterverein is an excellent resource and offers advice in multiple languages.
