Setting Up Utilities in a German Flat: The Checklist (2026)

Moving into a German flat, you flip the light switch and it works, so you assume the utilities are sorted. Sometimes they are, bundled into your rent; sometimes they are not, and you are unknowingly on the most expensive default tariff or about to face weeks without internet because nobody told you it takes that long to install. German utilities split confusingly between what your landlord handles and what you must arrange yourself, and they run on an estimated-payment-then-reconcile model that can spring a surprise bill once a year. Knowing which utilities are yours, how the contracts work, and the right order to set them up saves money and avoids the cold, disconnected first weeks.

This guide covers setting up utilities in a German flat: what is yours versus the landlord's, how electricity and internet work, the annual reconciliation, and the order to do it in. The checklist for a properly connected flat.

What is yours vs the landlord's

The first thing to establish: which utilities you arrange yourself, and which come through the landlord.

The typical split (but always check your contract, flats vary a lot):

• You arrange yourself: usually your own electricity contract and your own internet
• Often included via the landlord: water, heating, and building services, bundled into the Nebenkosten (additional costs) you pay alongside rent

So in many flats, electricity and internet are the renter's job, while water and heating are handled by the building and billed through the Nebenkosten. But this is not universal: some flats bundle more (occasionally even electricity) into the Nebenkosten; others leave most utilities to you. The only way to know is to read your rental contract and see exactly what the Nebenkosten covers.

So your first action in any new flat is to check the contract: what utilities are included in the Nebenkosten, and what must you set up yourself? That tells you which contracts to arrange. The two you most often handle personally are electricity (your own provider) and internet (always your own), so those are the focus below.

How electricity contracts work

For electricity, the German system has a quirk worth understanding: the default provider and the easy switch.

How it works:

• On moving in, you are automatically placed with the local default provider (Grundversorger) until you choose one
• The default is reliable but usually not the cheapest
• Switching to a better-value provider is easy and common, Germans do it routinely

So when you move in, you have electricity (good), but likely on the most expensive default tariff (less good). The money-saving move is to switch to a cheaper provider, a quick, standard process via comparison sites, that can noticeably cut your bill. Many newcomers never switch and overpay for years on the Grundversorger default.

How you pay: you pay a monthly amount based on estimated usage, then receive an annual reconciliation (below) comparing estimated to actual use. The monthly payment is an estimate; the yearly statement settles up.

So the electricity action is: you start on the default automatically, then switch to a better-value provider to save, and pay estimated monthly amounts settled by an annual bill. Payments go by SEPA direct debit from your German bank account, so have that ready.

The annual reconciliation

A concept that surprises newcomers and can spring a bill: the annual reconciliation (Abrechnung).

How it works across utilities (electricity, gas, and the Nebenkosten):

• During the year, you pay estimated monthly amounts
• Once a year, you get a statement (Abrechnung) comparing your estimated payments to your actual consumption
• If you used less than estimated, you get a refund
• If you used more, you owe the difference (a back-payment, Nachzahlung)

So unlike a pure pay-as-you-go system, German utilities estimate, then reconcile. Your monthly payment is a smoothing estimate; the real cost is settled annually. This is mostly convenient (steady monthly payments), but it means a possible back-payment once a year, especially for heating, which is hard to estimate and where a cold winter or higher usage can leave you owing a meaningful sum.

So budget for a possible annual back-payment, particularly on heating in the Nebenkosten reconciliation. Conversely, you might get a pleasant refund if you used less than estimated. The key is not to be blindsided: know that the Abrechnung is coming yearly, and keep a small buffer for a heating Nachzahlung. The full Nebenkosten reconciliation mechanics are in our Nebenkosten guide.

Internet timing and the setup order

Internet, the lead-time trap: of all the utilities, internet is the one that takes time.

• Getting connected can take a few weeks from ordering to activation
• Because of provider scheduling and technician appointments

So order your internet as early as possible, ideally the moment you have the flat (or even once your move-in date is confirmed), to avoid weeks without a home connection. Mobile data can bridge the gap, but the home internet itself often has a frustrating lead time you cannot rush. The single biggest internet mistake is ordering it after moving in and then spending a month tethering to your phone. Provider options are covered in our internet and mobile guide.

The setup order (the checklist): putting it all together, the right sequence for a new flat:

1. Check your rental contract, what is in the Nebenkosten vs what you arrange
2. Set up electricity: confirm you have the default provider, then switch to a better-value one
3. Order internet early, it has the longest lead time, so do this first among the things you control
4. Confirm heating and water arrangements (usually via Nebenkosten, but verify)
5. Set up SEPA direct debits from your German account for the contracts you hold yourself
6. Note the annual reconciliation is coming, budget for a possible back-payment

Doing this promptly and in order avoids the two classic failures: overpaying on the default electricity tariff for years, and spending your first weeks without internet. This fits within the broader arrival setup, and naturally follows your move into the flat.

The bottom line: German flat utilities split between what you arrange (usually electricity and internet) and what the landlord bundles into the Nebenkosten (often water and heating), so check your contract first. Switch off the default electricity provider to save, order internet early because it takes weeks, and budget for the annual reconciliation that can spring a heating back-payment. Set up your direct debits, follow the order, and your flat is properly connected without the common overpayments and gaps.

What to do this week

• Read your rental contract to see exactly what utilities are bundled into the Nebenkosten versus what you must arrange yourself (usually electricity and internet).
• Order internet immediately (it can take weeks), and after moving in, switch your electricity from the default provider (Grundversorger) to a cheaper one to save.
• Set up SEPA direct debits for your own contracts and budget for the annual reconciliation (Abrechnung), which can produce a heating back-payment.
