You can switch from Sky to BT Broadband with minimal disruption by checking your contract, confirming your activation date and following the UK’s One Touch Switch process. For eligible residential switches, your new provider generally coordinates the transfer, so you do not have to manage every step yourself.
However, a completely interruption-free switch is not guaranteed. Activation delays, installation requirements or technical faults can temporarily leave you without internet access.
Follow these seven steps to prepare your home, connect your BT Smart Hub and troubleshoot common problems if your new broadband does not work as expected.
How to Switch from Sky to BT Broadband Without Downtime
1. Check Your Sky Contract Before Ordering BT

Before ordering BT Broadband, review your existing Sky agreement. Leaving before your minimum contract term ends may result in early termination charges.
Check these details first:
- Contract end date: Confirm whether your minimum term has expired.
- Early termination charges: Ask Sky about any fees for leaving early.
- Bundled services: Check whether your broadband is linked to Sky TV, a home phone or another package.
- Email access: Find out whether leaving could affect an email service supplied by your provider.
- Landline number: If you want to keep your number, tell BT when ordering and confirm that the transfer is supported.
If your Sky package includes TV or other services you also want to stop, ask Sky whether those services need to be cancelled separately. Switching your broadband does not necessarily end every product or agreement on your account.
Once you understand the potential charges and service changes, choose a BT package that suits your household. Checking these details before ordering can help prevent unexpected costs and avoidable complications.
2. Order BT Broadband and Confirm Your Activation Date
Visit BT’s broadband switching page to compare available packages, check availability at your address and place your order.
Enter your address and account details carefully. Incorrect information can complicate the transfer, so review your order before submitting it.
After ordering, check your confirmation for:
- Your expected activation date.
- Whether an engineer appointment is required.
- When your BT Smart Hub should arrive.
- Instructions about your landline number or existing equipment.
- How to track your order and report delays.

Use the activation date confirmed by BT rather than assuming every switch takes the same amount of time. Your timeframe depends on your order, the connection available at your property and whether installation work is necessary.
If BT schedules an engineer visit, arrange access to your property as required. Keep your order confirmation available in case you need to query a delay.
3. Let BT Coordinate the Switch Through One Touch Switch
One Touch Switch is designed to make switching broadband providers simpler for eligible UK residential customers. Generally, you contact your new provider, which coordinates the switch with your existing provider.
When the standard process applies, you usually do not need to contact Sky separately to cancel your broadband.
To help the transfer go smoothly:
- Read switching messages from BT.
- Keep your Sky connection available while the transfer is being arranged.
- Follow BT’s instructions about installation and any phone-number transfer.
- Check for updates if your activation date changes.
Do not arrange a separate Sky broadband cancellation unless BT confirms that the standard switching process does not apply or gives you different instructions. Cancelling independently could complicate the transfer.
Remember that One Touch Switch cannot guarantee uninterrupted internet access. A short outage or activation delay may still occur.
For details about switching arrangements and consumer protections, read Ofcom’s broadband switching guidance.
4. Prepare Your Home Before BT Goes Live
Preparing your equipment before activation makes it easier to connect when your new service becomes available.
Before the changeover date:
- Locate your BT Smart Hub and power supply.
- Read the router setup instructions.
- Identify your broadband socket or fibre equipment.
- Keep your new Wi-Fi name and password accessible.
- Make a list of devices that will need reconnecting.
- Keep your phone available for order updates or engineer appointments.
If you depend on broadband for remote work, online classes or important calls, consider arranging a temporary mobile hotspot. Check your mobile signal and data allowance first, as video calls and large downloads can consume substantial data.
You may also want to avoid scheduling essential online activities around the expected changeover if even a short interruption would cause problems.
These preparations cannot prevent every fault, but they can save time when your new connection activates.
5. Connect Your BT Smart Hub When the Service Activates
When BT confirms that your broadband is ready, follow the instructions supplied with your Smart Hub. The exact connection method depends on the service installed at your property.
A typical setup involves these steps:
- Connect the Smart Hub to the correct broadband socket or fibre equipment.
- Connect the power supply and switch on the router.
- Allow the router time to start.
- Check its status lights against BT’s instructions.
- Connect your phone or computer using the supplied Wi-Fi details.
If the router needs several minutes to start, do not immediately assume activation has failed. If the connection remains unavailable, check your order status and follow BT’s troubleshooting instructions.
Your old Sky Wi-Fi name and password may not work automatically with the new router. Unless you configure compatible settings to match your previous network, you will probably need to connect your devices using the new Wi-Fi details.
Avoid factory-resetting the Smart Hub as your first troubleshooting step. Begin with basic connection checks because a reset can remove configuration settings.
6. Test Your Internet Connection Before Reconnecting Everything
Once the router indicates that the service is active, test the connection before reconnecting every device in your home.
Start with a phone or laptop close to the router. Open several websites and check whether they load consistently. Then test another device to see whether the problem affects your entire network or just one device.
If possible, connect a computer to the router using an Ethernet cable. A wired test helps distinguish a broadband connection problem from weak Wi-Fi coverage.

If the connection works but seems slower than expected:
- Run a speed test more than once.
- Test close to the router or use Ethernet.
- Pause large downloads during testing.
- Check the speed information for your BT package.
- Compare your results with the speeds BT says your line should typically achieve.
Wi-Fi performance can vary because of walls, distance, interference and device limitations. A slow wireless test does not necessarily mean your broadband line is faulty.

How to Tell Whether the Problem Is BT Broadband or Wi-Fi
If your new connection is not working as expected, identify where the problem is occurring before changing router settings.
- No device can access the internet: Check the Smart Hub’s status lights, physical connections and BT activation status.
- Only one device cannot connect: Check that device’s Wi-Fi settings, saved network and password.
- Devices connect but websites load slowly: Test close to the router or use Ethernet to help distinguish a Wi-Fi issue from a broadband performance problem.
- The connection repeatedly drops: Check for service updates and contact BT if the problem continues after basic troubleshooting.
These checks can help you explain the problem more clearly when contacting BT support. If the connection still drops out or websites fail to load, follow a relevant broadband connection troubleshooting guide if one is available on your site, or contact BT for further investigation.
7. Reconnect Your Devices and Check Your Home Network
After confirming that your new broadband works, reconnect your household devices, including phones, computers, smart TVs, games consoles, printers and smart-home equipment.

If a device cannot connect, open its Wi-Fi settings, select your BT network and enter the correct password. Check that you have selected the right network, particularly if your old Sky network name is still visible.
If you configured your new router to use the same Wi-Fi name and password as your previous network, some devices may reconnect automatically. This is not guaranteed, so check each device.
If only one device has a problem, restart it and check its saved network settings. If several devices cannot connect, check the Smart Hub status and confirm that the broadband service itself is working.
If your broadband works but certain devices keep disconnecting from Wi-Fi, consult a relevant Wi-Fi connectivity troubleshooting guide if one is available on your site. Otherwise, follow BT’s router guidance and avoid changing multiple settings at once.
What If Your BT Broadband Is Not Working on the Activation Date?

If BT broadband does not start working on the promised date, check your order confirmation for the scheduled activation time and any instructions from BT. After the activation window has passed, check for service updates and follow BT’s recommended restart procedure for your Smart Hub.
If the connection still does not work, contact BT and ask it to check whether your service has been activated correctly. Have your order number ready and explain the troubleshooting steps you have already tried.
Do not place a duplicate order while BT investigates. Ask whether activation is complete or additional work is required. If the issue remains unresolved, request a reference number and the next expected update, then follow BT’s formal complaints process if necessary.
What If Sky Disconnects Before BT Broadband Is Ready?
If your Sky connection stops working before your BT service becomes available, check your BT order status and contact BT promptly. Explain that your previous connection has stopped working and ask when your new service is expected to go live.
If you need internet access for work or essential tasks, consider using your phone’s mobile hotspot temporarily, provided your signal and data allowance are sufficient.
Keep records of the disconnection date, service interruptions and conversations with both providers. If the interruption lasts more than one working day, ask BT whether you qualify for compensation under the applicable switching rules. Eligibility depends on the circumstances, so do not assume every outage automatically qualifies.
Record when the service stopped and when it was restored. For details about your consumer protections, consult Ofcom’s broadband switching guidance.
Frequently Asked Questions
