In a Warsaw rental, almost every utility comes with the apartment: heating runs through the building, water hides inside the czynsz administracyjny, the electricity contract is usually in the landlord's name. Internet is the exception. It's the one service you choose, order, and pay for entirely yourself — and the one that can tie you to a 12–24 month contract in an apartment you might leave in a year.
That's why home internet in Warsaw deserves a tenant's approach, not an owner's: check what actually reaches the building, get the landlord's OK for any installation, and only then sign — ideally a contract you can walk away from without a penalty.
Check coverage before you sign the lease
The single most important thing to understand: fiber coverage in Warsaw varies not by district but by building. A new development in Wola might offer a choice of three fiber providers, while a pre-war kamienica two blocks away has only an old phone line or one cable operator. "Warsaw has fast internet everywhere" is true of the city — not necessarily of your address.
Checking takes five minutes and costs nothing:
- Use the address checker on each provider's site. Every major operator has a "sprawdź dostępność" (check availability) form — enter the street and building number to see what's offered there. Run the address through two or three providers before signing the lease.
- Ask the landlord. Was there internet in the apartment, with which provider, and is the wall socket still there? Reactivating an existing line is the fastest and cheapest scenario.
- Ask the neighbors, or glance at the stairwell. Operator stickers on the telecom cabinets are a surprisingly reliable guide to who's actually wired into the building.
Who to check first: Orange — the city's largest fiber network, covering more than half of Warsaw addresses; Play — owner of the biggest cable network since absorbing UPC, often the option in older buildings; T-Mobile and Netia — their own infrastructure plus access to other networks; Vectra — a cable operator strong in particular buildings and residential estates. Price-wise, expect 50–100 zł per month for 300–1000 Mbps, with introductory promos sometimes down to 30–40 zł.
If neither fiber nor cable reaches the building at all, there's mobile internet — a router with a SIM card. Speeds are less predictable, but there's no installation and usually no long contract.
Installation needs the landlord's consent
If there's no existing socket, getting connected means installation: drilling walls, running cable from the riser, sometimes work in the stairwell. That's an intervention in someone else's property, and it needs the owner's consent. Get it in writing — a messenger chat or an email is enough — before you place the order. Otherwise you're risking a conflict and a "damages" conversation when your deposit is returned.
If a socket is already there, everything is much simpler: usually it's just an activation or a provider switch on the same line, nothing gets drilled, and in practice no separate consent is needed. Which is why "what internet was here before?" is worth asking at the viewing.
The 24-month contract trap
The lowest advertised prices almost always come with a 12–24 month commitment. Fine for an owner, risky for a tenant: your internet contract can easily outlive your lease. Breaking it early means paying back the discount you received — capped, for contracts signed since late 2024, at the sum of the remaining monthly fees, but still easily a few hundred złoty.
What to do about it:
- No-commitment offers (bez zobowiązań). Nearly every operator has a no-fixed-term option — usually 10–20 zł per month more expensive, but you can cancel any time. If you might move within a year, this often beats the "cheap" tariff plus a penalty.
- Cesja — transferring the contract to the next tenant. Operators generally allow the contract to be signed over to another person with their approval. When you move out, offer your internet to the next tenant or the owner: they skip the installation, you skip the penalty.
- Moving the service to a new address. If your new address has coverage from the same operator, the service is usually transferred free or for a token fee. And if the operator confirms in writing that there's no technical possibility at the new address, you can typically terminate without a penalty.
- Return the equipment. After termination the router has to go back within the stated window (usually around 14 days) — otherwise a bill for the hardware lands on top of everything else.
A simple rule: your internet contract shouldn't be longer than your rental horizon — either take a no-commitment offer or ask the operator up front how cesja works.
Who pays: internet is your own contract
Unlike water and heating, which flow through the building as monthly advances and yearly settlements (how rozliczenie and dopłaty work), internet is a direct contract between you and the operator. The landlord isn't involved: there are no meters to transfer, no surprise top-up at the end of the year — you pay a fixed amount on your own tariff, and when you move out you take the contract with you or close it.
The one exception is "internet w cenie" — internet already connected and included in the rent. Convenient, but clarify before signing: whose name is on the contract, what happens if you want a faster tariff, and whether the owner's promo runs out halfway through your lease, taking the "included" price up with it.
In the overall cost picture, internet is a small but permanent line: it's part of the roughly 800 zł per month that Warsaw tenants pay on top of rent at the median (Passflat tenant data, August 2026). The full breakdown of what costs what beyond the rent is in the Warsaw rent prices report.
What to do before you sign the lease
Internet is the rare case where the tenant fully controls both the choice and the price. To keep that control from ending in a termination penalty, three steps are enough: check coverage at the address before signing the lease, get the landlord's written OK for installation, and don't sign an internet contract longer than your plans for the apartment.
And since you're checking the address anyway — check the whole building: its tenants may have already shared their real costs, from czynsz to dopłaty. Once you're connected and the first bills arrive, add your own numbers — it takes two minutes, no account needed, and the next tenant will have it easier.
