Common questions
How long does a switch between Brsk and BT Broadband take?
Under the UK One Touch Switch process introduced by Ofcom in 2024, most switches between two UK fixed-line broadband providers complete within ten working days. The gaining provider takes responsibility for the switch and your existing contract ends automatically. See Fibreswitch.com for the live status of your switch.
Will I lose service during the switch?
Most One Touch Switch moves between Openreach-based providers happen with no service downtime, because the underlying line stays connected. Moves between Openreach and a separate network (Virgin Media, Hyperoptic, Community Fibre, Netomnia, CityFibre via altnet retailer) can involve a brief overlap period to avoid any gap in connectivity. Your gaining provider will confirm the precise method during the order.
Can I keep my router?
Generally no. Most UK ISPs issue their own router optimised for their network and supply chain. You can use your own router on most Openreach FTTC and FTTP services, but bear in mind support and Wi-Fi guarantees apply to the supplied router. Cable, XGS-PON and certain proprietary altnet networks require the supplied modem or ONT.
Is the switch process the same in Northern Ireland?
One Touch Switch covers Great Britain. In Northern Ireland, switching processes follow Ofcom NI guidance and may differ for the Hull region where KCOM operates the historic incumbent network. Check with your gaining provider for region-specific guidance.
