For sole traders and home-based businesses SoGEA is fibre broadband without a landline: fibre to the cabinet, then copper to the building, with no phone service on the line. Openreach
Onestream home broadband
Onestream sells home full fibre, and part fibre without a landline (SoGEA), on 12, 18 or 24-month contracts. Its prices depend on your address, so it isn't in the table above, and you should ask about price rises during the contract before you sign. These are home plans: we haven't seen a business tariff on Onestream's site, so ask Onestream before ordering for business premises. Our Onestream guide.

Questions
What is true monthly cost?
The total you'd pay over the minimum term (monthly prices including stated rises and intro discounts ending, plus any stated set-up fee), divided by the number of months. It assumes you start in November 2026.
Do I need broadband with a phone line?
Not any more. Most business broadband now runs without an old analogue line, and the old network switches off on 31 January 2027. If you need a phone number, ask for a digital (internet) phone line.
