Hamburg Energie, Hamburger Energienetze, or Vattenfall? Registering Your First Electricity Is Still the Tenant's Job
If you've just moved into a Hamburg apartment with its own meter and haven't signed an electricity contract yet, registering is genuinely your job as the tenant, not your landlord's. Hamburg's setup genuinely confuses newcomers because it splits across three different companies with three different roles. Hamburg Energie, the city-owned green energy brand sold under Hamburger Energiewerke GmbH, is the dominant local choice most residents actively pick, but it is not who you automatically end up with if you register nothing. Hamburger Energienetze, formed in September 2024 from the merger of the city's separate electricity and gas grid operators, owns the physical wires and pipes and coordinates meter readings, a company you'll rarely contact directly since your chosen supplier handles that registration behind the scenes. The automatic fallback if you take no action at all, called Grundversorgung, actually still runs through Vattenfall Europe Sales GmbH for electricity and E.ON Energie Deutschland GmbH for gas, the same incumbent suppliers from before Hamburg bought its grids back in a 2013 referendum, not Hamburg Energie. At handover, get the meter reading (Zählerstand) and meter number from your landlord or the outgoing tenant, ideally written into your Wohnungsübergabeprotokoll. One current rule worth knowing: since 6 June 2025, retroactive electricity registration is no longer possible anywhere in Germany, so register on or before your move-in date. As of April 2026, Vattenfall's Grundversorgung Basis tariff runs 38.95 cents per kWh gross plus a 16.55 EUR monthly base fee, genuinely more than most tariffs you'd find actively comparing Hamburg Energie against competitors on Verivox or Check24.
The Official Rule
Assuming your landlord quietly sorts out electricity for a new Hamburg flat, or worrying you’re somehow expected to go through the Hausverwaltung, are both common but wrong starting points. Registering electricity for an apartment with its own meter is your job as the tenant. This is the same general principle that applies across Germany, and nothing about Hamburg’s ownership structure changes it, even though the city itself owns both the grid and a green-energy retail brand.
What actually trips people up in Hamburg specifically is that “the city owns the electricity company” doesn’t mean what it sounds like. Hamburg genuinely does own its energy infrastructure again, after a 2013 referendum, but that ownership is split across roles that matter differently to you as a new tenant.
| Company | Role | When you deal with them directly |
|---|---|---|
| Hamburg Energie (brand of Hamburger Energiewerke GmbH) | City-owned market supplier, one option among several you can actively choose | Signing a supply contract, if you pick them over a competitor |
| Vattenfall Europe Sales GmbH / E.ON Energie Deutschland GmbH | Grundversorger, the automatic fallback supplier for electricity/gas if you register with nobody | Only if you never actively choose a supplier |
| Hamburger Energienetze GmbH | Netzbetreiber, owns the physical grid, coordinates meter readings | Rarely, mainly for meter issues or submitting a reading directly online |
Hamburg bought this network back from private ownership through a genuine popular vote. On 22 September 2013, Hamburg residents voted in the “Energienetze” referendum, backing full municipal buyback of the electricity, gas, and district heating networks by a narrow but clear 50.9 percent, 444,352 votes to 428,980. The electricity grid (Stromnetz Hamburg) returned to full city ownership by February 2014, the gas network followed in January 2018, and district heating was fully back in public hands by 2019. A decade on, hamburg.de’s own anniversary report puts the city’s total acquisition cost across all three networks at roughly 1.93 billion EUR.
The grid side consolidated further in 2024. Hamburg’s own press release confirms that on 2 September 2024, the previously separate Stromnetz Hamburg and Gasnetz Hamburg merged into a single company, Hamburger Energienetze GmbH, now serving around 1.4 million households and businesses across more than 30,000 km of electricity lines and roughly 7,800 km of gas lines, and also tasked with building out the city’s hydrogen network (HH-WIN). This is genuinely a different company from Hamburg Energie, and one you’ll almost never contact directly: whichever supplier you sign up with handles your registration with Hamburger Energienetze behind the scenes.
Hamburg Energie itself started life as a response to the opposite problem. The brand was founded in 2009 as a subsidiary of Hamburg Wasser, created specifically because the city’s previous electricity utility, HEW, had been fully privatized into Vattenfall’s hands between 1999 and 2002. On 1 January 2022, Hamburg Energie merged with Wärme Hamburg (the formerly Vattenfall-owned district heating supplier the city had by then also bought back) to form Hamburger Energiewerke GmbH, a company Hamburger Energiewerke itself confirms is 100 percent owned by the Free and Hanseatic City of Hamburg. Hamburg Energie continues today as its retail electricity and gas brand.
None of that ownership history makes Hamburg Energie your automatic supplier, though. Hamburg’s own official page listing the region’s basic suppliers names the electricity Grundversorger as Vattenfall Europe Sales GmbH and the gas Grundversorger as E.ON Energie Deutschland GmbH, not Hamburg Energie. German energy law assigns Grundversorger status to whichever supplier serves the most household customers in a network area as of a set reference date, reassessed roughly every three years, and that status doesn’t automatically transfer to a newer municipal brand just because the city now owns the wires it runs on. In practice this means: if you move in and register with nobody, you don’t default to the city’s own green tariff, you default to Vattenfall (or E.ON for gas) at their Grundversorgung rate.
Meter Reading at Handover: What You Actually Need From Your Landlord
The one thing that genuinely is a shared moment between you, the outgoing tenant, and your landlord is the meter reading itself. At your Wohnungsübergabe (handover), get the meter number and the current Zählerstand written into your Übergabeprotokoll, and take a dated photo of the meter for your own records. Hamburger Energienetze’s own guidance is specific about when you’d submit this reading directly to them: at move-in or move-out, when switching suppliers, or if you’ve received an annual reading card, and notes that only the digits before the decimal point actually matter. You’ll need this same reading and meter number whether you submit it yourself or hand it to whichever supplier you sign up with, since they use it to register your connection with Hamburger Energienetze on your behalf.
Registering with a supplier itself is a short online process. Order a tariff from Hamburg Energie or a competitor, and the supplier takes it from there, submitting your registration to Hamburger Energienetze and waiting for confirmation from the grid operator and your previous supplier before your contract is confirmed, typically starting on the first of a month, at the earliest around three weeks after you order.
One genuinely current rule affects the timing, and it isn’t Hamburg-specific, it’s nationwide. Vattenfall’s own page on registering and deregistering contracts confirms that since 6 June 2025, a legal requirement means electricity contracts can only be registered or deregistered for a future date, with at least two business days’ notice, retroactive sign-ups are no longer possible anywhere in Germany. Register on or before your actual move-in date rather than waiting weeks afterward, the way it used to be possible to do.
What Real People Say
Newcomers who assume Hamburg’s city-owned energy company means “the city just handles it” describe genuine surprise on their first bill when they discover they’ve been paying Vattenfall’s Grundversorgung rate the whole time, not Hamburg Energie’s. The recurring advice from people who’ve been through the move: treat registering a supplier as a genuinely separate task from anything to do with your Anmeldung or your lease itself, since nothing about signing a rental contract automatically registers you for power.
People who’ve navigated a Hamburg handover specifically recommend photographing the meter the moment you get the keys, before boxes or furniture block access to it, and asking the outgoing tenant directly for the meter number rather than waiting to find it yourself, since it’s usually easiest to read straight off the previous tenant’s last bill.
Step by Step
- Ask your landlord or the outgoing tenant for the meter number and current Zählerstand at handover, and get both written into your Wohnungsübergabeprotokoll.
- Photograph the meter with a timestamp the day you get the keys, this protects you if a bill later looks wrong.
- Compare tariffs on Verivox or Check24, entering your postal code and consumption, Hamburg Energie is one option among several competing suppliers, not the only one worth checking.
- Register with your chosen supplier on or before your move-in date. Since 6 June 2025, retroactive electricity registration is no longer possible nationwide, so don’t wait.
- If you genuinely register nothing, know the automatic fallback is Vattenfall (electricity) and E.ON (gas), not Hamburg Energie, and it costs more (38.95 cents/kWh gross plus 16.55 EUR/month as of April 2026) than most actively chosen tariffs.
- If you ever need to submit a meter reading directly, Hamburger Energienetze’s own online portal accepts it using just your meter number and postal code.
Compliance Note
This page explains the general framework for registering electricity and gas as a tenant in Hamburg, current as of mid-2026. It is not legal or financial advice. Tariffs, Grundversorger designations, and registration rules can change, confirm your specific situation directly with Hamburg Energie, Vattenfall, E.ON, or Hamburger Energienetze before relying on any figure here.
FAQ & Common Pitfalls
We just signed a Hamburg lease and the flat has its own meter. Is registering electricity our job or the landlord's?
It's genuinely yours as the tenant, not your landlord's or the Hausverwaltung's. Nobody registers it automatically for you. The one narrow exception under German civil law is a fallback: if your landlord told you about it in advance and you still haven't signed your own contract by the actual handover date, they can pass your basic details to the Grundversorger so you're not left without power, but that's a safety net, not a substitute for registering yourself.
Hamburg's grid is city-owned and Hamburg Energie is the local brand. Doesn't that mean we automatically end up with Hamburg Energie if we don't choose anyone?
No, and this genuinely surprises a lot of newcomers. Hamburg Energie, sold under the fully city-owned Hamburger Energiewerke GmbH, is a market supplier you have to actively choose, exactly like any competitor. If you register with nobody at all, hamburg.de's own official page confirms the automatic Grundversorgung fallback is still Vattenfall Europe Sales GmbH for electricity and E.ON Energie Deutschland GmbH for gas, the same companies that supplied Hamburg before the city bought its networks back. Owning the grid and owning the fallback supply contract are two separate things under German energy law.
What's the actual difference between Hamburg Energie and Hamburger Energienetze, they sound almost the same?
Hamburg Energie is a retail brand, the entity you'd sign an actual supply contract with if you choose it, sold through Hamburger Energiewerke GmbH. Hamburger Energienetze is a completely different company, the Netzbetreiber that owns the physical cables and pipes, maintains them, and coordinates meter readings across the city, formed in September 2024 by merging the previously separate Stromnetz Hamburg and Gasnetz Hamburg. You'll almost never contact Hamburger Energienetze yourself: whichever supplier you sign up with, Hamburg Energie or otherwise, handles your registration with the grid operator on your behalf.
Can we still register our electricity if we've already been living here a couple of weeks without a contract?
Not retroactively, no. Since 6 June 2025, a nationwide legal requirement means electricity contracts can only be registered or deregistered for a future date, with at least two business days' notice, never backdated. Register as soon as you can rather than waiting, and in the meantime you're not without power: the Grundversorgung fallback (Vattenfall) supplies you automatically from move-in regardless of whether you've signed anything, it's simply the more expensive default rather than a chosen tariff.
What should we actually get from the landlord or the previous tenant at handover?
The meter reading (Zählerstand) and the meter number, ideally written into your Wohnungsübergabeprotokoll alongside a dated photo of the meter itself. You'll need both figures whether you're registering with a new supplier or submitting the reading directly to Hamburger Energienetze's own online meter portal, and a documented reading at handover protects you if a bill later looks wrong, since it proves what you actually inherited rather than what the previous tenant used.
