The Complete Guide to UK Leased Line Costs in 2025

What is a Leased Line?

A leased line provides your business with a dedicated, private circuit for internet connectivity and data communications. Unlike standard broadband, this symmetric connection delivers identical upload and download speeds through a dedicated fiber line that isn't shared with other businesses.

How Leased Lines Differ from Broadband

While standard broadband might seem sufficient for smaller operations, leased lines offer several critical advantages:

Feature

99.9% to 99.999%

Standard business broadband connections share bandwidth with neighboring businesses and homes, leading to fluctuations in speed, especially during peak usage times. This shared nature means your internet access can become unreliable precisely when you need it most.

Technical Benefits of Leased Lines

Leased lines offer several technical advantages that make them ideal for businesses with demanding connectivity requirements:

  • Symmetrical Speeds: Unlike broadband's asymmetric design (faster download than upload), leased lines provide identical speeds in both directions. This is crucial for businesses that regularly upload large files, host servers, or use cloud-based applications.
  • Low Latency: Leased lines deliver significantly lower latency (the delay in data transmission) than standard connections. In 2025, typical leased line latency is under 15ms compared to 30-50ms for standard broadband. This reduced delay is vital for applications like VoIP, video conferencing, and real-time data processing.
  • High Uptime: With guaranteed uptime of 99.9% or better (many providers now offer 99.999% or "five nines" reliability), leased lines minimize costly downtime. This translates to less than 5 minutes of unplanned downtime per year with a 99.999% SLA.
  • Dedicated Connection: Your bandwidth isn't shared with other businesses, meaning consistent performance regardless of what others in your area are doing online.

Business Applications

Leased lines support a wide range of business needs and applications:

  • Video Conferencing: High-quality video meetings require consistent, reliable connections with low latency. Leased lines ensure your important client presentations aren't interrupted by buffering or quality issues.
  • Cloud Services: As more business applications move to the cloud, reliable internet access becomes essential. Leased lines provide the consistent performance needed for smooth operation of Software-as-a-Service (SaaS) applications, cloud storage, and virtual desktops.
  • VoIP and Unified Communications: Voice and video communications are highly sensitive to connection quality. Leased lines deliver the low latency and consistent bandwidth necessary for crystal-clear voice calls and video communications.
  • Data Backup and Disaster Recovery: Regular backup of critical business data requires substantial upload bandwidth. Symmetrical speeds make this process faster and more reliable.
  • Multiple Site Connectivity: Businesses with multiple locations can use leased lines to create secure, high-performance networks connecting all sites.

Factors Affecting Leased Line Costs

Understanding what drives leased line pricing helps you make informed decisions and potentially identify cost-saving opportunities. Several key factors determine how much you'll pay for your connection:

Bandwidth Options

The bandwidth you choose has the most significant impact on your monthly costs. As your speed requirements increase, so does the price:

100Mbps Pricing

Entry-level leased lines typically start at 100Mbps. This speed is suitable for small to medium businesses with moderate internet usage needs.

Typical usage scenario: Small offices with 10-20 employees using cloud applications, email, and occasional file transfers.

Average monthly costs across providers (2025):

  • Urban areas: £175-£270
  • Suburban areas: £195-£290
  • Rural areas: £220-£320

1Gbps Pricing

1Gbps (1000Mbps) connections provide enterprise-grade performance suitable for larger organizations or those with higher bandwidth demands.

Typical usage scenario: Medium to large businesses with 50+ employees, heavy cloud usage, frequent video conferencing, and regular large file transfers.

Average monthly costs across providers (2025):

  • Urban areas: £300-£450
  • Suburban areas: £350-£500
  • Rural areas: £400-£650

10Gbps Pricing

These ultra-high-speed connections are designed for organizations with exceptional bandwidth requirements.

Bearer Capacity

The bearer capacity of your leased line determines both your current service and future flexibility.

Explanation of Bearer vs. Committed Rate

The bearer is the physical capacity of your leased line connection, while your committed rate is the guaranteed bandwidth you pay for. For example, you might have a 1Gbps bearer with a committed rate of 200Mbps, meaning you can upgrade to anywhere between 200Mbps and 1Gbps without requiring new physical infrastructure.

Cost Implications of Different Bearer Sizes

Bearer Size
Available Speed Range
Monthly Premium
Typical Installation Costs
100Mbps
10Mbps-100Mbps
None
£0-£1,500 (36+ month contract)
1Gbps
100Mbps-1Gbps
5-15% more than direct 100Mbps
£0-£2,000 (36+ month contract)
10Gbps
1Gbps-10Gbps
15-25% more than direct 1Gbps
£1,500-£3,500 (36+ month contract)

Future-Proofing Considerations

Selecting the right bearer capacity requires balancing current costs against future needs:

  • Bandwidth growth trends: Most businesses see 20-30% annual bandwidth growth
  • Upgrade costs: Increasing speed within your bearer typically costs £20-30 per additional 100Mbps
  • Physical installation: Changing bearer size requires new physical installation
  • Technology evolution: Consider emerging applications your business might adopt

A future-proof approach often means selecting a bearer that accommodates 3-5 years of anticipated growth, typically one step above your current needs.

Contract Length

The duration of your contract significantly impacts both monthly costs and installation fees.

12-Month Options and Costs

Short-term contracts offer maximum flexibility but at a premium:

  • 30-40% higher monthly costs compared to 36-month terms
  • Full installation fees typically apply (£1,500-£3,000)
  • Most suitable for businesses with uncertain future plans or temporary locations

24-Month Options and Costs

Mid-term contracts balance flexibility with better pricing:

  • 15-25% higher monthly costs than 36-month terms
  • Reduced installation fees (often 50% discount)
  • Good option for businesses expecting significant changes within 2-3 years

36-Month Options and Costs

The standard contract length offering optimal pricing:

  • Baseline pricing used for most advertised rates
  • Installation fees usually waived on standard installations
  • The most common choice for established businesses

60-Month Options and Costs

Long-term contracts provide maximum cost savings:

  • 5-15% lower monthly costs than 36-month terms
  • Installation fees waived, sometimes with additional incentives
  • Best for stable businesses in owned premises with predictable connectivity needs

Contract Negotiation Tips

To secure the best contract terms:

  • Compare quotes from multiple providers
  • Negotiate based on competitor pricing
  • Consider bundling with other services (voice, cloud, security)
  • Ask about mid-contract bandwidth flexibility
  • Request SLA improvements rather than just price reductions
  • Discuss installation fee waivers for shorter contracts

Location and Distance Factors

Your physical location significantly impacts leased line costs and availability.

Urban vs. Rural Pricing Differences

60-90 days
3-5 providers
Rural Areas
30-50% higher
90-120+ days
1-3 providers

Distance from Exchange Impact

The proximity to the nearest point of presence (PoP) or exchange directly affects costs:

  • Under 2km: Minimal impact on pricing, standard rates apply
  • 2-5km: 10-20% premium on monthly costs
  • 5-10km: 20-35% premium, potential for additional installation costs
  • 10km+: Substantial premiums, often 40%+ over baseline rates

These distance-based costs reflect the provider's expense in connecting your location to their core network.

Excess Construction Charges Explained

Excess Construction Charges (ECCs) cover the costs of building new infrastructure to reach your premises:

  • What triggers ECCs: Lack of existing duct infrastructure, need for road crossing, difficult terrain
  • Typical costs: £50-£150 per meter of new duct work
  • Impact range: From zero to £20,000+ depending on survey results
  • Mitigation options: Longer contracts often include ECC absorption by the provider
  • Alternative solutions: Wireless leased lines can sometimes avoid ECCs altogether

Frequently Asked Questions

Common Questions About Leased Line Pricing

What's the minimum leased line speed available?

Most providers offer starting speeds of 100Mbps, though some offer 10Mbps or 50Mbps options in certain areas. Lower speeds don't always mean proportionally lower costs due to fixed infrastructure expenses.

Can I change my bandwidth during the contract?

Yes, most providers allow bandwidth changes within your bearer capacity. Upgrades are typically processed within days, while downgrades may have contractual limitations or notice periods.

Are there any usage limits on leased lines?

Unlike broadband, leased lines typically don't have data caps. You're paying for a guaranteed bandwidth that you can utilize 24/7 at 100% capacity if needed.

Technical Questions

What's the difference between bearer and committed rate?

The bearer is the physical line capacity, while the committed rate is your guaranteed minimum bandwidth. For example, a 1Gbps bearer with 100Mbps service can be upgraded to any speed up to 1Gbps without new physical installation.

How reliable are leased lines compared to broadband?

Leased lines typically offer 99.9% to 99.999% uptime guarantees, equating to just minutes of downtime per year compared to potential hours or days with standard broadband.

What equipment do I need for a leased line?

Providers typically supply a termination unit and router. For higher bandwidths (1Gbps+), you may need to ensure your internal network infrastructure (switches, cabling) can support these speeds.

Contract and Provider Questions

What's the minimum contract length?

Most providers offer 12-month minimum terms, though these come with higher monthly costs and installation fees. Standard terms are 36 months, with 60-month contracts offering the lowest monthly costs.

Can installation fees be waived?

Yes, most providers waive standard installation fees on 36+ month contracts. Some will waive fees on shorter contracts in competitive areas or when winning business from competitors.

Why are there such price differences between providers?

Price variations reflect different infrastructure ownership, service levels, support quality, and target markets. Some providers focus on premium service, while others compete primarily on price.

Is it worth using a leased line broker or consultant?

Brokers can save time by gathering multiple quotes and may access better pricing through volume discounts. However, comparison platforms now offer similar benefits with transparent, real-time pricing.
