Switching

Leaving BT Business? How to switch, keep your numbers and avoid surprises.

By David White, Director, Padel Services · Updated October 2026

The short answer

You can leave BT Business at any time, but leaving before your contract ends usually means an early termination charge set by your terms. Ask BT for your end date and the exact charge in writing. Your numbers can come with you, and your new provider arranges the move.

Find your end date and what leaving costs

Your contract end date and any early termination charge are in your BT account and terms. Ask for both in writing before you decide, so you are comparing real figures.

You do not have to wait

Being in contract puts you in a strong position. Where it makes sense we build the settlement into the deal so it never touches your cash flow, up to an agreed figure and subject to approval. We confirm what is possible before you sign anything.

Who does the moving

We arrange the move of your numbers and lines, and build your new system before we arrive. Your old service stays live until your numbers move, so nothing goes quiet on the day.

The questions businesses ask.

Can I leave BT Business before my contract ends?

Yes. Leaving early usually means an early termination charge from BT, set by your terms. Ask BT for the exact figure in writing.

How do I find my BT contract end date?

It is in your BT Business account and your contract. If you cannot find it, ask BT, or send us your bill and we will help you work it out.

Do I cancel BT myself?

For lines and numbers we move, the switch is arranged as part of the move. Some services, like broadband you are not moving, you cancel yourself once the new service is live. We tell you which is which.

Can I keep my numbers, and is there a charge for porting?

Yes, your numbers come with you. Ofcom rules say you cannot be charged directly for porting a number.

BT has put my price up. Can I leave without a penalty?

It depends on what your contract says about price changes. Ofcom gives business customers rights when a change is not in their favour, so it is worth checking your terms.
