Ofcom is reviewing Openreach's proposed October fibre and Ethernet prices
The wholesale prices behind full-fibre broadband and leased-line connections are under review ahead of changes due on 1 October, with a decision expected in the autumn. It is the pricing that shapes what a business connection costs at renewal.
- 05The Switch-Off
The final copper line-rental rise lands on 1 October
Openreach's legacy line rental has already risen twice this year and the last increase is due on 1 October, close to doubling the 2025 cost. With about half a million business lines still on old copper, planning the move to digital is cheaper than paying to stand still.
What we’re watching
Microsoft's next monthly security update lands in August, so keeping your updates current stays on the list. On connectivity, Ofcom's decision on Openreach's proposed October prices for full fibre and leased lines is due in the autumn and will shape what a business connection costs at renewal, and the last of this year's copper line-rental rises arrives on 1 October. If you want a straight answer on what any of this means for your setup, that is a phone call away.
