Switching internet provider in Belgium without downtime

Switching provider without losing a day of connectivity is possible in Belgium, and the rule fits in one sentence: never cancel yourself. Easy Switch hands the cancellation to the incoming provider, which activates its services before having the old ones cut. Here is the real timeline, the cases where downtime stays unavoidable, and the scale owed if the switch goes wrong. Recorded on 3 September 2026.

Can you really switch internet provider without downtime?

Yes. In the vast majority of cases, at least.

The Easy Switch procedure, imposed on providers by BIPT (Belgian Institute for Postal Services and Telecommunications) since 1 July 2017, rests on a very simple order of operations: activate first, deactivate afterwards. Telenet writes it plainly on its help page, and it is the single most important sentence in this whole file: you are the one who chooses when your old subscriptions are stopped, on the day the new ones are activated at the earliest, or later. Orange takes the same line by letting you specify how many days your old services should stay live once its own are installed.

That deliberate overlap is the entire mechanism. You pay two subscriptions for a few days, and you never lose the line.

The condition lies elsewhere: the two subscriptions have to be able to coexist technically.

One physical line, or two separate networks

The whole difference sits there, and no Belgian comparison site states it clearly.

If your future provider uses a different infrastructure from the current one, the two services run in parallel without interfering: two sockets, two modems, two live subscriptions during the transition. If both brands travel over the same cable into your home, the overlap is physically impossible. Orange admits as much on its own Easy Switch page for moves between Orange and hey!: the two services use the same cable, which makes simultaneous use impossible.

Nicolas's own analysis, built from the terms published by the providers and recorded on 3 September 2026. The Orange to hey! row is confirmed by Orange itself.

The practical consequence is counter-intuitive: changing network is more comfortable than changing brand. Two neighbours on the same street may not even have the same options, since the wholesale network deployed at the address, Proximus, Fiberklaar or Wyre, dictates the catalogue you can actually subscribe to. Our guide to checking fibre availability at your address explains how to find out before ordering.

How long does a provider switch take, day by day?

Between three days and three weeks, depending on how the connection is made.

The only regulated delay is the start: the incoming provider must trigger the procedure within two working days of your request, provided it holds your customer number and your Easy Switch ID. The rest depends on the ground.

Delays recorded on 3 September 2026 from the official pages of Proximus, Telenet and Orange, and from the obligations published by BIPT. A fibre connection still to be pulled to the home falls outside this timeline and is counted in months.

One administrative constraint slips into the middle. Telenet accepts Easy Switch details online up to three days before installation, or on the day itself if an engineer visits. After that, the train has left.

The procedure in seven steps

1. Find your Easy Switch ID and your customer number at the top of your bill, in your customer area or in your current provider's app. Since October 2023 a check number accompanies the ID.
2. Check what serves your address before choosing. Two separate networks beat a change of brand on the same line.
3. Order from the new provider and sign the Easy Switch mandate. Do not warn the old one, cancel nothing, send no letter.
4. Explicitly request the transfer of your phone numbers. Without that request they stay with the old provider.
5. Set the stop date of the old contract after activation of the new one, not on the same day. Three to seven days of overlap cost a few euros and remove all risk.
6. Request retention of your email address before the subscription ends, never afterwards.
7. Return the equipment on time and keep proof of deposit. The full procedure is set out in our guide to cancelling and switching provider.

What if the downtime happens anyway?

Claim, and know what is automatic.

Three compensations have coexisted since the scheme was strengthened on 2 October 2023, when the missed-appointment payment rose from €10 to €30. Nobody publishes them side by side, yet they do not follow the same rules.

Easy Switch scale in force since 2 October 2023, recorded on 3 September 2026 from the official pages of Orange Belgium and Telenet. Amounts are credited on the next bill issued in the customer's name.

The example given by BIPT speaks for itself: old service cut on the Thursday, new service live on the following Tuesday, and €30 is owed to you automatically. Add the billing rule, which is often forgotten: the provider you are leaving must stop billing its services by the end of the day following the day it was informed of your transfer. If you then get nowhere, the Ombudsman Service for Telecommunications handles this type of dispute free of charge.

Can you keep your landline number and your email address?

Both can be kept, and both are lost by omission. Here are the points to check before signing.

• The landline number only follows you if you request the transfer. By default it stays with the old provider, as BIPT explicitly points out.
• Telephony left behind is a poorly documented Belgian trap: Telenet warns that VOO, edpnet and Scarlet do not offer telephony without internet or TV. Moving the internet alone therefore means losing the number at those three providers.
• The email address is kept free of charge for eighteen months, on request, under article 121/1 of the Electronic Communications Act of 13 June 2005. The provider cannot refuse.
• Beyond eighteen months, a Royal Decree in force since 1 January 2024 allows an extension, again on request, for a maximum of €1.50 per month.
• The request must be made before the subscription ends. Filed afterwards, it has no object.
• TV recordings and content stored with the provider do not transfer. Back them up first.

Does the switch work the same way in all three regions?

The procedure is federal and strictly identical in Brussels, Flanders and Wallonia. The risk of downtime is not, because it depends on the infrastructure present in the street.

In Flanders and Brussels, the coexistence of a dense cable network and an advanced fibre rollout, on the order of 78 % of homes passed in Brussels and 71 % in Flanders according to mid-2026 figures, makes changing network easy, and therefore makes the overlap almost always possible. In Wallonia, where the rate sits around 44 %, some streets still have only the old former-VOO coaxial network or Proximus copper: the room for manoeuvre narrows there, and switching from one brand to another on the same line is more common. Check the BIPT coverage atlas to see what actually serves your address, then the official meilleurtarif.be comparison tool for prices.

One closing remark, less procedural. A successful provider switch is not judged on changeover day but twelve months later, when the promotion expires and the bill returns to its real level. We compare that price, physical network by physical network, in our ranking of the best fibre internet deals in Belgium. Switching cleanly is pointless if it lands you on an offer that will cost more than the last one.
