Which is cheaper, BT Broadband or Sky Broadband?

Headline pricing across BT and Sky is closely matched, with promotional pricing typically £25 to £30 per month for entry full fibre. Out-of-contract uplifts are similar.

Is BT faster than Sky Broadband?

Real-world speeds for the same Openreach line are effectively identical between BT and Sky; the difference is entirely router and Wi-Fi. BT Smart Hub and Sky Hub are broadly comparable; Sky Wi-Fi Max and BT Complete Wi-Fi both offer mesh-style guarantees.

Which has wider coverage, BT or Sky?

Both BT and Sky sell across the full Openreach footprint, which is effectively nationwide for FTTC and a majority for FTTP. Coverage is functionally identical.

Which should I choose, BT or Sky?

Choose BT for the safest mainstream brand and broader Halo bundle value. Choose Sky if your household already pays for Sky TV or Sky Mobile.

Who is each provider best for?

BT suits households who want the largest UK broadband brand with strong support and complete bundle reach. Sky suits households already inside the Sky TV or Sky Mobile ecosystem.

Can I switch between BT Broadband and Sky Broadband?

1. Check availability at your postcode for both providers. Coverage matters more than the headline brand.
2. Compare like-for-like on speed, contract length and total cost of ownership for 12 to 24 months.
3. Use One Touch Switch to move. Your new provider does the heavy lifting.
4. Test your speed after the switch on UKSpeedTest.co.uk and complain if it materially underperforms.

Common questions

How long does a switch between BT Broadband and Sky 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.
