Direct answer: You can often keep your router when you switch broadband, but only if it is compatible with the new network and the new provider permits it. Retaining it can preserve familiar Wi-Fi settings, but provider-supplied equipment is usually the simplest route to supported installation and fault checks.
Key takeaways
- Your existing router must support the connection type at your new address.
- A full fibre service may require separate equipment where the cable enters your home.
- Using your own router can limit the help available if a connection fault occurs.
- Check the total contract cost, set-up charge and any stated price rises before agreeing to switch.
Can I keep my router when switching broadband?
Yes, provided it works with the new service and your provider allows third-party equipment. A router is not automatically tied to the broadband company that supplied it. What matters is whether it can connect correctly to the technology installed at your address and whether you have the settings needed to configure it.
The practical decision is not simply whether an older router still powers on. Ask whether it supports the connection you are moving to, has enough wired ports for your home office or other equipment, and provides dependable Wi-Fi coverage where you need it. If the new service is FTTC, cable or full fibre, the connection method may differ from the one your current router expects.
There can also be a support trade-off. A provider may ask you to reconnect its supplied router before investigating a fault. Keeping that router in a cupboard is sensible, even if you prefer your own equipment day to day.
Will my router work with full fibre?
It depends on whether the router can connect to the equipment fitted for your full fibre service. Full fibre, also called FTTP, brings fibre to the property rather than relying on the older copper section used by FTTC. This can change what plugs into your router.
Some full fibre installations use a separate network termination box inside the home. In that arrangement, your router connects by Ethernet cable. Other arrangements require a router with a specific fibre-compatible connection. Do not assume that a router used on an FTTC line will work unchanged on full fibre.
Before ordering, confirm the access technology shown for your exact address and ask the new provider whether it supports customer-owned routers. This is especially worthwhile if you are moving home, because availability and installation requirements can change from one street, or even one flat, to another. Full fibre availability should always be checked by address rather than assumed from a nearby property.
Should I use the new provider's router instead?
For most households, starting with the supplied router is the clearest and lowest risk option. It should arrive configured for the service, which reduces the chance of an avoidable delay on activation day. It also gives the provider a known starting point if you report a connection or Wi-Fi problem.
Your own router can still be the better choice where it has stronger Wi-Fi coverage, more Ethernet connections or settings that matter for a home office or small business. The key is to separate a broadband line fault from an in-home Wi-Fi issue. If the supplied router works but your own router does not, the problem is likely to be configuration or compatibility rather than the incoming service.
A sensible approach is to use the supplied router first, check that the connection is stable, then connect your existing router if you still want to use it. Record any settings before changing equipment, and keep cables and packaging until the switch is settled.
What should I check before keeping my router?
Check compatibility, support rules and your whole contract cost before you commit. The table below sets out the questions that prevent the most common surprises.
| What to check | Why it matters | Practical action |
|---|---|---|
| Connection type | FTTC, cable and FTTP may need different router connections. | Confirm the technology available at your exact address. |
| Provider support | Fault testing may be limited with your own equipment connected. | Keep the supplied router available for diagnostic checks. |
| Installation timing | A new full fibre installation can require an appointment. | Do not dispose of working equipment before activation is confirmed. |
| Total contract cost | A lower monthly price may not show every charge. | Review set-up fees, contract length and stated price changes. |
Current month prices, speeds and installation options vary by postcode and address. Compare the stated monthly charge alongside any upfront fee and the contract term. From 17 January 2025, new contracts must show any mid-contract price rises in pounds and pence at the point of sale, rather than linking rises to inflation (Ofcom, 2024). That makes it easier to judge the likely total cost, but you should still read the contract wording carefully.
Can I switch broadband without losing my connection?
Usually, the new provider manages the switch, but installation work or a home move can affect timing. One Touch Switch went live on 12 September 2024 and is run by TOTSCo. Under this process, the customer contacts only the new provider, which then manages the switch process (TOTSCo, 2024).
That does not mean every switch is identical. A move to full fibre may need a visit to install equipment, whilst a transfer at an address with the right service already in place may be more straightforward. Renters should also check any permissions needed for work to the property, particularly where a new cable must be brought inside.
Avoid cancelling your existing broadband before the new provider confirms the planned activation route. If reliable connectivity matters for remote work or a small business, ask about installation timing before placing the order and retain a backup plan for the appointment window. A short period using the supplied router can also make first day testing simpler.
Does keeping my router save money?
It may reduce unnecessary equipment use, but it should not decide which broadband contract you choose. The more meaningful comparison is the full cost over the minimum term: monthly charges, set-up fees, the length of commitment and any stated mid-contract increases. A router you already own is only valuable if it is compatible and meets your household's Wi-Fi needs.
Do not pay more for a slower or less suitable service purely to avoid changing equipment. Equally, do not assume a low headline monthly price is the best value if it comes with a fee, a longer commitment or conditions that do not fit a planned house move. The right speed depends on how many people use the connection at once, whether you work from home and how much of your home relies on Wi-Fi rather than wired connections.
For many households, the most balanced choice is to accept the provider router, test it properly, then decide whether your existing router offers a genuine improvement.
What if my own router does not work after switching?
Reconnect the supplied router first, then check whether the broadband service itself is live. This is the quickest way to establish whether the issue is with the incoming connection or with your own equipment. If the supplied router connects successfully, check the configuration instructions for your router and confirm that it supports the new connection type.
If neither router connects, contact the new provider and explain what has happened. Give clear details of the activation date, any installation work completed and the lights or messages shown on the supplied equipment. This keeps fault checking focused on the service rather than an unsupported configuration.
Do not factory reset your own router until you have noted its current settings. That can remove Wi-Fi names and passwords you may want to restore later. If your router is several years old and coverage has been unreliable, switching equipment may be the simpler fix than spending time on repeated adjustments.
Frequently asked questions
Can I use my old router with a new provider?
Often, yes. It must be compatible with the new connection type and configured with the correct settings. Ask the new provider whether customer-owned routers are supported. Keep the supplied router, because it may be needed for installation checks or fault diagnosis.
Do I need a new router for full fibre?
Not always. Some full fibre installations allow a router to connect through a separate network termination box by Ethernet. Others may require a different connection method. Confirm the installation arrangement at your address before relying on an existing FTTC or cable router.
Can I return the provider router if I use my own?
Follow the return instructions in your contract and keep the equipment until you know whether it is required. Providers may expect their hardware back when a contract ends. Retaining it during the service can also make support and diagnostic checks less complicated.
Will switching broadband affect my Wi-Fi name and password?
It can. A new router may use a different Wi-Fi name and password, so devices may need reconnecting. If your existing router remains in use, you can usually keep its current Wi-Fi details, subject to successful configuration for the new broadband service.
Is One Touch Switch available for every broadband switch?
One Touch Switch is designed so the customer contacts only the new provider, which manages the switching process (TOTSCo, 2024). Installation needs, a house move or a change in access technology can still affect the steps and timing for an individual order.
If you are weighing up whether to keep your router, start with the service available at your exact address, then judge the contract on transparent total cost and support as well as Wi-Fi convenience.
