Is a Leased Line Faster Than Business Broadband?
A clear, direct answer to this question — written for UK business owners and IT decision-makers.
Direct Answer
A leased line provides dedicated, symmetrical speeds guaranteed to your business alone — typically 100Mbps to 10Gbps up and down. Business broadband shares capacity with other users, so speeds vary. For cloud-heavy businesses, VoIP users, or those with SLA requirements, a leased line's consistency matters more than peak speed. AMVIA recommends leased lines for businesses running mission-critical applications or handling high call volumes.

Frequently Asked Questions
SD-WAN can reduce WAN costs by approximately 50% compared to traditional MPLS. The UK SD-WAN market is projected to grow from $4.8 billion in 2025 to $14.6 billion by 2031. SD-WAN is complementary to — not a replacement for — dedicated leased lines for primary connectivity.
A leased line provides dedicated, uncontended bandwidth exclusively for your business. Unlike broadband, leased lines guarantee symmetrical upload and download speeds with 99.9% uptime SLAs. Fixed leased lines account for over 39% of UK business internet connections.
Standard installation takes 30-90 working days depending on whether existing fibre infrastructure reaches your premises. The critical pricing factor is distance — premises beyond 20 miles from a provider's nearest Point of Presence see costs rise 30-50% for the same speed.
This depends on your number of users and applications. VoIP requires approximately 100 Kbps per call. Cloud applications and video conferencing need more. The UK average business broadband speed is 131 Mbps, but 20% of UK businesses report insufficient internet speeds for their needs.
UK businesses lost £3.7 billion to internet outages in 2023. Small businesses lose £350-£450 per minute of downtime. 92% of UK businesses take 24 hours or longer to recover from a significant outage. Backup connectivity and failover solutions are essential for business continuity.
