Both leased lines and full fibre broadband deliver fast, reliable internet to UK businesses — but they serve very different needs. This honest guide breaks down the differences so you can choose right.
Get a Free Quote →Full fibre is the right choice for most SMEs — it delivers excellent speeds at a competitive monthly cost, and with 4G failover the reliability gap has almost disappeared. Leased lines remain the best option for businesses with mission-critical connectivity needs, symmetrical traffic requirements, or who need guaranteed SLA response times. Telexico provides both — contact us and we'll recommend the right product for your usage and budget.

A leased line is a dedicated, uncontended circuit — your bandwidth is yours alone, 24/7. Broadband is shared between many users on the same network. Leased lines also come with guaranteed fault fix SLAs, static IPs and symmetrical speeds as standard.
For most small businesses, full fibre broadband with 4G failover delivers sufficient reliability at a fraction of the leased line cost. Leased lines make sense when your business cannot tolerate any downtime, handles large data transfers, or runs an on-site phone system with 20+ simultaneous calls.
Full fibre broadband typically costs £30–£150/month. A leased line starts at around £200/month and can reach £2,000+ for higher speeds. Most businesses find full fibre with failover to be 70–90% cheaper.
Yes — and this is a popular configuration. A leased line as primary with full fibre or 4G as automatic failover gives you the best of both worlds.
