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 been one of the biggest challenges for expats and immigrants in recent years. Rising construction costs, high demand in major cities, and limited housing stock have pushed rents upward across the country. The Greix Rent Index for 2026 offers a fresh, data-driven picture of where rents stand today — which cities are still within reach, which have become significantly more expensive, and what trends are shaping the market. Whether you are relocating to Germany for the first time or considering a move between cities, this data can make a real difference to your budget and your quality of life.
The Greix Rent Index is one of Germany's most closely watched benchmarks for residential rental prices. It tracks actual transaction data rather than listed asking prices, which makes it a more reliable indicator of what tenants are genuinely paying. In 2026, the index confirms a pattern that many renters have already felt in their wallets: rents in Germany's largest metropolitan areas continue to outpace income growth, while several smaller and medium-sized cities remain considerably more affordable.
Cities in the eastern and northern parts of Germany — including several in Saxony, Saxony-Anhalt, and Mecklenburg-Vorpommern — continue to offer some of the lowest average rents in the country. These regions attract expats who work remotely or in local industries that do not require a presence in a major hub. By contrast, Munich, Frankfurt, and Stuttgart remain at the top of the price ladder, with average cold rents for a standard two-room apartment well above the national average.
The steepest increases in 2026 are not always in the cities you might expect. While Munich and Hamburg continue their upward trajectory, mid-sized cities that were once considered affordable alternatives — such as Leipzig, Nuremberg, and Freiburg — have seen significant rent growth as demand catches up with their improved infrastructure and quality of life. The so-called "overflow effect," where renters priced out of major cities move to nearby alternatives and push prices up there in turn, is clearly visible in the data.
For expats, this means that the strategy of choosing a second-tier city to save money is becoming less straightforward. The window of affordability in some of these cities is narrowing, and acting sooner rather than later may be advisable if you are considering a move.
Understanding the rent landscape matters beyond just finding a place to sleep. In Germany, your registered address (Anmeldung) determines access to local services, your assigned Ausländerbehörde, and in some cases your eligibility for certain social benefits. Choosing a city purely for immigration convenience while ignoring rental costs can create financial strain that affects your overall integration experience.
If you are on a tight budget — for example, receiving Bürgergeld or starting a new job — cities in eastern Germany or smaller western cities may offer a more sustainable entry point. Families with children may also want to factor in Kindergeld and local childcare availability alongside rent costs when comparing locations.
It is also worth noting that Germany's rental regulations, including the Mietpreisbremse (rent brake), apply differently depending on the city and the type of property. In cities where the rent brake is in force, landlords are legally limited in how much they can charge above the local reference rent (Mietspiegel). Knowing your rights as a tenant from day one can prevent you from overpaying.
Based on the Greix Rent Index, smaller cities in eastern Germany — particularly in Saxony-Anhalt and Mecklenburg-Vorpommern — consistently rank among the most affordable for renters. Cities like Chemnitz and Magdeburg offer significantly lower average rents compared to western counterparts of similar size. However, affordability should always be weighed against local job market conditions and transport links.
Yes, Munich remains at the top for rental costs in 2026, followed closely by Frankfurt and Stuttgart. Average cold rents for a two-room apartment in Munich are substantially higher than the national average, making it particularly challenging for newcomers who have not yet established a stable income in Germany.
Yes. Germany's Mietpreisbremse applies in many cities and means that new rental contracts cannot exceed the local Mietspiegel by more than 10 percent in designated areas. This applies to all tenants regardless of nationality. If you believe your landlord is charging above the legal limit, you can formally challenge the rent. Tenant associations (Mieterverein) offer advice and support, including for non-German speakers.
Yes, indirectly. Your Anmeldung address determines which Ausländerbehörde handles your residence permit applications. Some offices are known to have longer waiting times or different internal practices. This is worth researching before you commit to a location, especially if you need to renew or upgrade your Aufenthaltstitel soon after arriving.
The 2026 Greix Rent Index is a useful tool for any expat making housing decisions in Germany this year. The key takeaways: major cities remain expensive and are still rising; mid-sized cities that were once affordable are catching up quickly; and eastern German cities continue to offer the best value for money, provided they match your professional and personal needs.
Before signing any rental contract, research the local Mietspiegel, consider joining a Mieterverein for tenant support, and factor in all the practical implications of your chosen city — from job access to Ausländerbehörde waiting times. Housing is one of the most consequential decisions you will make as an expat in Germany, and being informed gives you a real advantage.
