How much does a leased line cost?
Leased lines are dedicated, symmetrical broadband connections that offer the most reliable and stable high-speed internet connection available to UK businesses.
The costs for this premium service range from as low as £2,500 per year to over £15,000, depending on the agreed bandwidth, business location, contract length, installation difficulty and add-ons.

Top tips to pay less on leased line
The cost of a leased line isn’t fixed and depends on several factors your business can control. Reduce your expenses by following these tips:
Compare leased line quotes
Accurately assess your current and future broadband and network requirements to optimise your spending. Request quotes from multiple providers to negotiate a better deal or leverage price-matching offers.
Commit to a long-term contract
Choosing a longer-term agreement (3–5 years) can significantly reduce monthly fees and may include additional discounts.
Factors affecting leased line costs
The total cost of your leased line will depend on the following factors:
Bearer capacity
The maximum speed your leased line infrastructure can support ( typically 1 Gbps or 10 Gbps) depending on your scalability needs.
Circuit speed
The speed your provider guarantees in the Service Level Agreement (SLA), often tiered at 100 Mbps, 500 Mbps, 1 Gbps, or 10 Gbps.
Enhanced SLA
Premium SLAs ensure higher uptime and better support but come with added costs.
Provider premium
Pricing also depends on the provider’s reputation, costs, and customer acquisition strategies.
Contract length
Longer contracts (3–5 years) lower fees and may include perks like free installation or enhanced SLAs.
Installation complexity
Complex leased line installations incur Excess Construction Charges (ECCs) for trenching, laying ducts, securing wayleaves or extending fibre long distances.
Location
Urban areas have lower costs due to dense fibre networks, short distances to hubs and access points, abundant backhaul infrastructure, and intense competition from multiple providers.
Managed leased line
Many businesses choose to outsource the security, monitoring and support for their leased line at an extra cost.
Add-On services
Extras like managed leased lines, VoIP, or SD-WAN cost extra but are cheaper when bundled than bought separately.
Types of leased line costs
All leased line broadband deals include one-time setup costs and recurring monthly expenses. Below is a comprehensive breakdown with cost estimates provided by our business broadband experts:
Recurring costs
Recurring costs are typically charged every month through the duration of the contract:
Broadband service fee
This fee covers the broadband service provided to you to the standard of your SLA.
Cost estimate: £200 – £1,500+ per month
Enhanced Service Level Agreements (SLAs)
Businesses requiring higher uptime guarantees or faster response times can opt for an enhanced SLA, ensuring optimal performance.
Cost estimate: £50 – £200 per month
Managed leased lines
Specialised third-party providers may offer leased line management services, relieving your IT department of tasks like remote network monitoring, maintenance, 24/7 support, cyber security software, and broadband scalability.
Cost estimate: £100 – £400 per month
UCaaS & VoIP
Some providers bundle UCaaS or a business VoIP phone system with leased line connections for businesses with high call volumes, with costs depending on specific VoIP features.
Cost estimate: £10 – £50 per month, per user. See our business VoIP costs article for further details.
SD-WAN and SASE
Businesses operating across multiple premises usually add SD-WAN or SASE solutions, which enable centralised network management across multiple leased line contracts.
Cost estimate: £200 – £600 per month
One-time costs
One-time leased line costs are usually paid upfront upon signing a business broadband contract and include:
Broadband setup fee
This one-off cost covers leased line setup, including router installation and network configuration. Many providers waive this fee for contracts lasting three years or longer. See our business broadband installation guide to understand what happens in practice.
Cost estimate: £500 – £1,000+
Excess Construction Charges (ECCs)
This fee applies to any additional engineering work required to install your leased line. This might involve extending fibre to your premises, setting up Network Termination Equipment (NTE), or construction tasks such as trenching, duct installation, pole upgrades, or wayleave agreements.
Cost estimate: £1,000 – £10,000+
Local Area Network (LAN) setup
Managed leased line providers may also offer LAN setup services. This includes configuring network switches, business broadband routers and mesh networks to optimise your internal network for leased line performance. Costs vary based on complexity and scale.
Cost estimate: £1,000 – £10,000+
