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.

Finding an affordable flat in Germany has never been easy for newcomers, but 2026 is adding new pressure in some unexpected places. Nationally, rent increases have been relatively modest — barely keeping pace with inflation — but that headline figure masks dramatic variation from city to city. If you are planning to move to Germany, relocating within the country, or simply renewing a lease, understanding where rents are rising fastest could save you thousands of euros and a great deal of frustration. Spoiler: the cities topping the charts may not be the ones you expect.
Across Germany as a whole, rental price growth in the past year has been comparatively restrained. After the sharp spikes seen in 2022 and 2023, the market appeared to be cooling at a national level. Inflation has remained the main reference point for most landlords operating within the legal framework of rent control mechanisms like the Mietspiegel (local rent index).
However, averages can be deeply misleading when it comes to German housing. The country's rental market is hyper-local, shaped by university enrollment figures, regional economic growth, infrastructure investment, and internal migration patterns. In several cities, these forces are combining to push rents upward at a pace that far outstrips both inflation and the national average.
While The Local's full data is specific, the broad trend reported points to smaller and mid-sized cities — not the usual suspects like Berlin or Munich — leading the surge in 2026. Cities that have attracted significant investment, new tech or logistics hubs, or large numbers of internal migrants from more expensive cities are seeing the sharpest rent hikes.
This reflects a well-documented pattern: as workers priced out of top-tier cities relocate to secondary markets, demand in those markets climbs rapidly while housing supply struggles to keep pace. Construction timelines in Germany remain long, planning permissions are slow, and the social housing stock has shrunk significantly over the past two decades.
For expats, this has a very practical implication: do not assume a city is affordable simply because it is not Frankfurt, Munich, or Hamburg. Research current listings and the local Mietspiegel before signing any contract.
Germany has relatively strong tenant protections compared to many other countries, and expats should be aware of the key tools available to them.
Mietspiegel: Most cities publish a local rent index that sets a reference range for what landlords can charge for a comparable flat. Landlords re-letting a flat generally cannot charge more than 10% above the Mietspiegel figure (and in some areas with Mietpreisbremse — rent brake — the cap is even tighter).
Mietpreisbremse: In designated areas with tight housing markets, landlords are restricted in how much they can raise rents when signing a new contract. Not all cities have this in place, so check whether your target city is covered.
Kündigung (notice periods): German rental contracts are heavily weighted in favor of tenants when it comes to eviction. Landlords must provide significant notice and have limited legal grounds for termination.
If you believe your landlord is charging above the legal limit, you can contact a local Mieterverein (tenants' association). Membership fees are modest and the legal advice they provide can be invaluable.
Navigating the German rental market as a foreigner comes with extra hurdles. Landlords frequently request extensive documentation: proof of income, the last three payslips, a SCHUFA credit report, and sometimes even a letter from your employer. Here is how to prepare:
Search for the Mietspiegel of the specific city or district where the flat is located. Most municipal websites publish this. Enter the flat's characteristics (size, age, features) to find the reference rent. If the asking price is significantly above this figure, you may be able to negotiate or challenge it legally — consult a Mieterverein for advice.
Having no SCHUFA history is different from having a negative one. Many landlords will accept alternative proof of financial reliability, such as bank statements, a letter from your employer confirming your salary and contract type, or a Bürgschaft (guarantor). Be transparent with landlords and proactively provide as much supporting documentation as possible.
Rents in Germany are not rising uniformly, and 2026 is a year to approach housing decisions with up-to-date, city-specific information rather than assumptions. Whether you are arriving for the first time or considering a relocation within Germany, research the local Mietspiegel, understand your legal rights as a tenant, and prepare your documentation in advance. The German rental market rewards preparedness and penalizes those who rush in without doing their homework.
