Direct answer: How to switch broadband provider: a step-by-step UK guide starts with checking whether you are in or out of contract, comparing deals at your address, then placing the new order. In many cases, One Touch Switch lets your new provider manage the move. You still need to check notice, installation timing, early exit fees and whether you want to keep your home phone number.
- Check your current contract end date before you do anything else.
- Use One Touch Switch where available, because your new provider usually handles the transfer.
- If you want to keep a landline number, tell the new provider before ordering is finalised.
- Avoid overlap charges by matching activation and notice dates carefully.
- Moving to a different network, such as Virgin Media or some altnets, can involve a different process.
If your contract is ending soon, or your current deal no longer looks good value, the best first step is to compare broadband deals by postcode: https://broadbandswitch.uk/compare/. That shows what is actually available at your address, which matters because FTTP, FTTC, cable and altnet coverage vary street by street.
When can you switch broadband provider?
You can switch at any time, but the cost and process depend on your contract status.
If you are out of contract, switching is usually straightforward. You can place a new order and move with little risk beyond timing the change properly. If you are still in contract, you can still leave, but early termination charges may apply, and those can wipe out the value of a cheaper deal.
Your latest bill, online account or contract paperwork should show your minimum term end date. Providers such as BT, Sky, TalkTalk, Vodafone, EE and Plusnet also send end-of-contract notifications. Those notices are useful because they usually confirm your current monthly price and what it may rise to if you stay put.

How does the One Touch Switch process work?
One Touch Switch is designed to make most UK residential broadband switches simpler.
Under One Touch Switch, you normally contact your new provider, not your old one. The gaining provider arranges the transfer and keeps you updated. This reduces the chance of accidental double cancellations or unnecessary loss of service. Ofcom introduced the process to make switching easier for consumers.
Once you place the order, the new provider will usually confirm key details, including the proposed switch date and whether any engineer visit is needed. Your existing service stays live until the agreed handover date in most standard switches.
There are exceptions. If you are moving from or to a provider on a different type of network, the process may not be identical. Virgin Media uses its own network, and some altnets do too. In those cases, you may need to deal with cancelling the old service yourself, so read the order journey carefully rather than assuming everything is automatic.
What notice period do you need to give?
Notice periods vary, so check your provider's terms before you commit.
Many switches handled through One Touch Switch do not require you to separately serve notice in the usual way, because the transfer itself triggers the closure of the old service. Even then, you should still verify whether any chargeable notice period applies, especially if you are leaving a bundled broadband and phone package or moving to a different network.
A common mistake is assuming that ordering a new line automatically ends the old one. That is not always true. If the switch is not covered by the gaining-provider process, your old broadband may keep billing until you cancel it.
This is where provider trade-offs matter. Openreach-based providers often fit more neatly into the standard switching journey. Cable and some full fibre altnets may involve separate activation and cancellation steps.

Can you keep your landline number when you switch?
Yes, often you can, but only if you ask early and the transfer is eligible.
If you still use a home phone number, tell the new provider at the point of sale that you want to keep it. Do not cancel the old service yourself before the number transfer is arranged, because that can cause the number to be lost.
Number porting is usually more straightforward when you are switching between compatible services and keeping the same address. It can be less predictable if you are moving home, changing network type, or leaving a legacy landline setup as providers migrate customers towards digital voice services.
If keeping the number matters for family, work calls or business use, ask the new provider to confirm the process before installation is booked. Small firms and home offices should be especially careful here, because losing a published number can be disruptive. If that applies to you, the business broadband hub is a useful next step: https://broadbandswitch.uk/business-broadband-hub.html
How do you avoid overlap charges and double billing?
The safest approach is to line up activation, notice and final billing dates before the switch goes live.
Overlap charges happen when your new service starts before your old one has properly ended, or when a final notice period runs on after migration. Sometimes a short overlap is worth it if you work from home and cannot risk downtime. Often, though, it is avoidable.
Use this quick check before ordering:
| What to check | Why it matters | What to do |
|---|---|---|
| Minimum term end date | Leaving early can trigger exit fees | Check your latest bill or account before switching |
| Switch type | Not all moves are covered the same way | Ask if One Touch Switch applies to your order |
| Activation date | Starting too early can cause overlap | Choose a date close to your old service end date |
| Notice requirements | Some services still need separate cancellation steps | Read the provider's confirmation and terms carefully |
| Equipment returns | Late returns can add extra charges | Keep return packaging and proof of postage |
Also watch for setup fees and in-contract price rises. A cheaper monthly deal is not always cheaper overall. If budget is the priority, compare shortlists that focus on total value, such as deals under £25: https://broadbandswitch.uk/broadband-deals-under-25.html and options under £30: https://broadbandswitch.uk/broadband-deals-under-30.html
What if you are moving home or upgrading to full fibre?
A home move or technology change can alter the normal switching process.
If you are moving, broadband at the new address may be available from different providers and on different terms. Never assume the same package can simply be transferred. New-build areas, blocks of flats and rural properties can be particularly mixed, with Openreach FTTP, FTTC, Virgin Media or altnets available in different combinations.
If you are upgrading from FTTC to FTTP, installation timing matters. Full fibre can need a new ONT, a new router, or an engineer appointment. That can justify a planned overlap if you cannot afford interruption. If full fibre is available where you live, reviewing FTTP broadband deals first can help you decide whether a speed upgrade is worth the contract commitment: https://broadbandswitch.uk/fttp-broadband-deals.html

A simple step-by-step way to switch
The best way to switch is to treat it as a timing exercise, not just a price comparison.
First, check your current provider, contract end date, monthly price, and whether any early exit fees apply. Second, compare available deals at your exact address, not just your postcode area, because available networks can differ even on the same road.
Third, choose the deal based on total contract cost, not the lowest monthly price alone. That means looking at setup fees, in-contract rises, contract length and whether the package suits your speed needs. Fourth, confirm whether One Touch Switch applies and whether the new provider will manage the transfer.
Fifth, if you want to keep a phone number, raise that before the order is completed. Sixth, choose an activation date that reduces the risk of paying for two services longer than necessary. Finally, return old equipment promptly and keep records until the final bill is settled.
If cost pressure is part of the reason you are switching, it may also be worth checking whether you qualify for a social tariff before committing to a new standard deal: https://broadbandswitch.uk/social-tariffs-uk.html
FAQs
Do I need to cancel my old broadband before switching?
Usually no, if your switch is covered by One Touch Switch, because the new provider normally manages the transfer. If you are moving to a different network, check carefully, because separate cancellation may still be needed.
Will I lose service on the day I switch?
Often there is little or no downtime, but it depends on the network and whether installation is required. Full fibre upgrades and some home moves can involve a longer changeover.
Can I switch broadband if I am still in contract?
Yes, but you may have to pay early termination charges. Always compare those costs against any savings from the new deal.
Can I keep my landline number?
Often yes, especially if you are staying at the same address and the transfer is compatible. Tell the new provider immediately that you want to keep the number, and do not cancel the old line first.
How do I avoid paying for two broadband services at once?
Check your notice terms, confirm the switch type, and pick an activation date that lines up closely with the end of your existing service. A short overlap can be sensible if you rely on broadband for home working.
Is switching worth it if my service works fine?
Often yes, especially once you are out of contract and prices rise. Even if you stay with a similar speed, a new deal can offer better overall value or a better fit for your current needs.
