What's Happening with Broadband in Castleton?
Castleton residents in Bury are well placed when it comes to broadband connectivity. Full fibre (FTTP) is available at speeds of around 887 Mbps, putting the area significantly ahead of the UK national average.

No specific Openreach expansion announcements for Castleton or the wider Bury area were found in recent ISPreview reporting at the time of writing. The absence of news is itself a reasonable indicator: areas that already have strong FTTP coverage tend to generate fewer headlines than those still waiting for it.
In terms of providers, Openreach's network serves as the primary full fibre infrastructure here, with all the major ISPs selling packages over it, including BT, Sky, EE, Vodafone, Plusnet, and TalkTalk. The Greater Manchester geography means CityFibre has also been active in the region, so it is worth checking whether their network extends to your specific street, as this would give you an additional choice of providers such as Zen Internet, Vodafone, or Giganet.
One change affecting every household in Castleton is the PSTN copper switch-off. Openreach has confirmed the analogue phone network will close in January 2027, with all voice calls moving to digital (VoIP) services delivered over your broadband line. If you still use a traditional landline, you will need to confirm with your provider that you are migrated to a digital alternative before that date.
