FAQs: leased line cost calculator How much does a leased line cost in the UK?
A leased line can cost from around £150-£300+ per month for lower-speed dedicated internet, with higher-speed 500Mbps, 1Gbps and 10Gbps services costing more. Final pricing depends on postcode, contract length, installation and provider availability.
Why are leased lines more expensive than broadband?
A leased line gives your business dedicated bandwidth, stronger service levels and usually symmetrical upload and download speeds. Standard broadband is normally shared and less guaranteed.
Is a 100Mbps leased line enough?
A 100Mbps leased line may be enough for small offices, VoIP, cloud apps and everyday business use. Larger teams or businesses with heavy uploads may need 500Mbps or 1Gbps.
Is a 1Gbps leased line worth it?
A 1Gbps leased line can be worth it for larger teams, cloud-heavy businesses, high upload requirements, multi-site operations and companies that need guaranteed bandwidth.
What is a bearer?
The bearer is the maximum capacity of the circuit. For example, a business may buy a 100Mbps service on a 1Gbps bearer, allowing easier upgrades later.
Do leased lines have installation fees?
Some leased line installations are included, but excess construction charges may apply if extra work is needed to connect your premises.
How long does leased line installation take?
Installation times vary by provider, building and network availability. Survey, wayleave and construction requirements can affect timescales.
Can I get a short leased line contract?
Some providers may offer shorter contracts, but 36-month and 60-month terms are often more cost-effective.
Should I choose a leased line or FTTP?
FTTP may be enough for many SMEs, but a leased line is usually better if you need dedicated bandwidth, stronger upload performance, SLA-backed service or critical uptime.
Can I compare leased line quotes for free?
Yes. You can compare leased line quotes based on your postcode, speed needs, contract length and business requirements.
