Five scenarios where London businesses choose dedicated fibre.
Leased lines are 3-10x more expensive than equivalent FTTP, take 30-90 days to install vs 7-14 for FTTP, and only make commercial sense for specific operational profiles. Honest assessment for London businesses:
- High-availability operations. Where downtime cost genuinely exceeds £500+/hour — financial services, regulated industries. SLA with financial credits is operationally and commercially valuable.
- Heavy upload requirements. Video conferencing teams, large file uploads to cloud, off-site backup. Symmetric bandwidth means uploads don't bottleneck.
- VoIP-heavy operations. 50+ concurrent calls with consistent quality requirements. Contended FTTP can introduce jitter at peak times; leased line removes that variability.
- Multi-site connectivity. Where multiple London sites need consistent bandwidth between them — often as MPLS or SD-WAN underlay.
- Contractual bandwidth guarantees. Regulated industries or specific customer contracts requiring dedicated capacity.
For typical London SMEs (5-50 staff, standard cloud apps, voice on a separate VoIP system), FTTP with 4G/5G failover usually delivers leased-line-like effective uptime at much lower cost. We'll tell you which fits your operation honestly.
How leased lines actually arrive at your building.
One of the most competitive uk fibre markets — openreach fttp, cityfibre rollout, hyperoptic in multi-dwelling buildings, community fibre, virgin media business, colt for high-bandwidth leased lines. Different delivery methods have different cost, install timeline, and SLA profiles.
EAD (Ethernet Access Direct)
Pure fibre from your London premises to the Openreach core. Strongest SLA, best for London operations where uptime is genuinely critical. Bandwidth: 10Mbps to 10Gbps. Typical 30-60 day install in urban London, longer if civil engineering needed.
EoFTTC (Ethernet over Fibre To The Cabinet)
Fibre to the local cabinet, copper for last few hundred metres. Cheaper than EAD, still uncontended, slightly weaker SLA. Good middle option for London businesses where cost matters but contention does not.
Pure point-to-point fibre
Direct fibre from premises to provider point-of-presence, no shared infrastructure. Used for very high-bandwidth requirements (10Gbps+) common in London's financial and tech sectors.
EFM (Ethernet First Mile)
Copper-based, legacy product, declining availability. Generally avoided for new installs. Mentioning it for completeness — if your existing setup is EFM, modernising to EAD is usually the right move.
Where in London we deliver.
Every E, EC, N, NW, SE, SW, W, WC postcode covered. Different districts have different fibre infrastructure profiles — we check honestly what's available at your specific address.
City of London (EC1-EC4)
Financial services density, regulated industries, leased-line frequency above UK average. SLAs matter more than headline pricing.
Canary Wharf (E14)
Modern building stock, dense fibre infrastructure, multiple carrier options. Strong 5G coverage. Consultancy and finance SME concentration.
Shoreditch / Tech City (EC2/N1)
Creative, tech, media businesses. Heavy cloud-app usage. Multiple alt-net options including CityFibre and Community Fibre.
West End (W1, WC1, WC2)
Mixed retail, hospitality, professional services. Building stock varies — some postcodes excellent FTTP, others older buildings face install complexity.
King's Cross / Euston (N1/WC1)
Tech and consultancy concentration. Strong fibre infrastructure, multiple carriers. Common managed-office tenants.
South Bank / London Bridge (SE1)
Mixed corporate and hospitality. Newer infrastructure dominates. Strong leased-line availability.
How we deliver leased lines in London.
We're Wolverhampton-headquartered (64 Chapel Ash WV3 0TT). For physical leased line install in London, the civil engineering and fibre work is delivered through Openreach or your chosen carrier's field engineering team — the same engineers who'd install for BT, Virgin, Colt, or any other provider.
What that means:
- Carrier-agnostic quoting. We quote across Openreach, Virgin, Colt and other carriers in London — recommending what genuinely fits your operation, not what makes us highest margin.
- Project management. We coordinate the install timeline with you, the carrier, and your building's landlord/facilities team if needed. No "we'll be in touch" open-ended commitments.
- Ongoing relationship. Single named UK engineer for your account. The carrier handles physical fibre faults via their SLA; we handle the service relationship around it.
- SLA enforcement. Carrier SLA terms are negotiated upfront and committed in your contract. Financial credits if SLA missed — chased on your behalf, not buried in support tickets.

Frequently asked questions
How much does a leased line cost in London?
Typical 2026 London leased line pricing: £300-500/month for 100Mbps symmetric EAD, £400-650 for 200Mbps, £600-1000 for 500Mbps, £800-1500 for 1Gbps. Higher bandwidth (10Gbps+) typically £2,000-5,000+/month. London install costs typically £500-3,000 for standard urban deployments. Complex civils (digging, fibre runs) add significantly. We quote across multiple carriers and pick best fit for your operation.
How long does leased line install take in London?
Typical London leased line install: 30-60 working days for urban locations with existing duct infrastructure. 60-120 days for sites needing new fibre runs. The bottleneck is civil engineering work (Openreach or alt-net scheduling) — not the provider. For interim connectivity during the install window, we deploy FTTP + 4G failover so your operation stays online.
What's the difference between EAD and EoFTTC in London?
EAD (Ethernet Access Direct) is pure fibre end-to-end — strongest SLA, highest cost. EoFTTC is fibre to the cabinet, copper for the last few hundred metres — cheaper, slightly weaker SLA, still uncontended. Both are valid choices for London businesses depending on cost/SLA priorities. We'll recommend honestly based on your operation.
Do I need a leased line in London or is FTTP enough?
For 95% of London SMEs: FTTP with 4G/5G failover delivers leased-line-like effective uptime at much lower cost. Leased lines genuinely earn their cost when: downtime cost exceeds £500+/hour, you need symmetric heavy-upload, you have 50+ concurrent VoIP calls with quality requirements, or contractual SLAs from your customers require dedicated bandwidth. We assess honestly — most London businesses don't actually need leased line.
Can leased lines support multi-site businesses in London?
Yes — leased lines are the standard underlay for multi-site connectivity. For 3+ London sites needing consistent bandwidth between them (often as MPLS or SD-WAN underlay), leased line at each site is the right choice. We coordinate the multi-site rollout, manage install timelines across sites, and configure inter-site routing.
What SLA do London leased lines come with?
Standard 99.95% uptime SLA with 4-hour fix-time for London leased lines, with financial credits if SLA missed. Pure EAD products typically come with the strongest SLA; EoFTTC slightly weaker but still business-grade. SLA terms are committed upfront in your contract — no surprise small print.
How does Telexico deliver leased lines in London?
We're Wolverhampton-headquartered. For London leased line install, physical fibre work is delivered by Openreach or your chosen carrier's field engineering team — same engineers who install for BT, Virgin, Colt. We quote across carriers (vendor-agnostic), project-manage the install, enforce SLA terms, and provide ongoing support via single named UK engineer.
