If your business is based in London and you’re exploring high-capacity connectivity solutions, a 100Gb leased line offers unmatched speed, performance, and reliability. Designed for enterprises with demanding digital infrastructure, a 100Gb leased line provides a private, uncontended connection between your premises and your internet provider — delivering symmetrical speeds of up to 100Gbps.
But what does it cost to install and maintain such a powerful internet solution in the UK’s capital? This guide breaks it down.
What Affects 100Gb Leased Line Costs in London?
The cost of a 100Gb leased line in London depends on several factors, including:
- Location Within London
Businesses in central areas like Canary Wharf or The City may enjoy lower installation costs due to better infrastructure. However, sites in outer boroughs or newly developed zones may face higher fees due to additional engineering work. - Distance from the Carrier’s Network
If your premises are close to a provider’s existing fibre network, installation is faster and more affordable. The further away you are, the higher the construction and delivery cost. - Contract Length
Providers typically offer lower monthly rates for longer-term contracts (36 months+), and may waive install fees altogether. - SLAs and Support Packages
Premium support, guaranteed uptime (e.g. 99.99%), and faster fault resolution times can influence the overall pricing. - Additional Services
Managed routers, security add-ons, and traffic monitoring tools may be included in a bundled price or charged separately.
Typical Pricing in 2025
While pricing will vary by provider and business needs, here’s a general guide:
- Installation Costs: £0 – £5,000+ (often free with 3–5 year contracts)
- Monthly Rental: £3,000 – £7,000+ depending on distance and contract terms
Note: 100Gb leased lines are premium solutions, typically adopted by data centres, ISPs, large enterprises, financial institutions, and media firms with enormous bandwidth needs.
Benefits of 100Gb Leased Lines for London Businesses
Ultra-Fast Performance
London’s fast-paced business environment demands dependable internet. A 100Gb line ensures you’re never limited by bandwidth — whether you’re hosting services, managing real-time data, or enabling remote work at scale.
Business Continuity
Avoid costly downtime. SLAs with guaranteed performance protect operations and ensure resilience during peak hours.
Future-Proof Infrastructure
As digital transformation accelerates, businesses will require faster and more stable internet. A 100Gb leased line ensures you’re ready for tomorrow’s bandwidth demands.
Compliance and Security
London-based firms in finance, healthcare, or legal sectors benefit from the security and privacy that dedicated lines offer — meeting strict data protection standards.
Is It Worth the Cost?
For small businesses or startups, a 100Gb leased line may exceed their needs. But for large-scale companies, tech firms, or cloud-reliant teams, it can be a cost-effective investment — especially compared to combining multiple lower-bandwidth lines or dealing with inconsistent broadband performance.
If uptime, speed, and reliability are mission-critical to your operations, then yes — it’s worth every penny.
