UK business internet typically ranges from £30-£60/month for FTTC (fibre to the cabinet), £40-£100/month for FTTP (full fibre), and £300-£800/month for a dedicated leased line, depending on speed and contract length. Leased lines cost more but offer guaranteed symmetrical speeds not shared with other users.
FTTC uses fibre to a street cabinet then copper to your building, capping realistic speeds around 60-80Mbps. FTTP runs fibre directly to your premises, supporting speeds up to 1Gbps. A leased line is a dedicated, uncontended fibre circuit just for your business, guaranteeing speed and uptime - this calculator compares 3-year costs across all three.
For most UK SMEs under 20 staff, FTTP is usually sufficient and considerably cheaper. A leased line becomes worthwhile once you rely heavily on cloud applications, VoIP, video conferencing, or need guaranteed uptime for revenue-critical systems, since it offers symmetrical speeds and an SLA that broadband typically doesn't.
Business broadband contracts commonly run 12-36 months, while leased lines usually require 36-60 month terms due to the installation costs involved. Shorter contracts generally carry a higher monthly price, so this calculator lets you compare total 3-year cost across different contract lengths and connection types.
