What Is a Leased Line Internet Connection?
A leased line is a dedicated, business-grade internet connection built exclusively for your organisation. Unlike standard broadband, it delivers symmetrical upload and download speeds, guaranteed bandwidth, and an uncontended connectionmeaning you never share capacity with other users.

For London SMEs, this means rock-solid reliability, crystal-clear video calls, faster cloud access, and an internet connection that performs consistently, even during peak hours.

Reliable Connectivity for Day-to-Day Business Operations

Modern businesses depend on uninterrupted internet for video conferencing, VoIP, cloud applications, and file sharing. A business leased line in London removes performance drops and downtime, giving your team a stable connection that keeps operations running smoothly without disruption.

Ideal for businesses that cannot afford slow speeds, outages, or unreliable connectivity.

Scalable Speeds That Grow With Your Business

As your business scales, so do your connectivity demands. Leased line broadband is fully scalable, allowing you to increase bandwidth as required  without changing infrastructure.Perfect for growing SMEs adopting remote working, cloud software, Microsoft 365, VoIP phone systems, and data-heavy applications.
