Leased line quotes in the UK can differ by hundreds of pounds—even when the specifications appear similar. But why is there such a wide variation in price between providers? Understanding the reasons can help you make informed choices and avoid overpaying.
1. Infrastructure Ownership vs Reselling
Some providers own their fibre infrastructure (like Openreach or Virgin Media), while others lease it and resell services.
- Infrastructure Owners: Often cheaper and faster in their own network zones.
- Resellers: Rely on third-party infrastructure, may charge more to cover wholesaler fees.
Knowing who physically delivers the line helps explain cost differences.
2. Geographic Location and Coverage
Your postcode plays a big role:
- Urban Areas: Better coverage, more competition, lower costs.
- Rural Locations: Longer installation routes, fewer providers, higher prices.
For example, a leased line in central London might cost £250/month, while a rural site in Cumbria could pay over £600/month for the same speed.
3. Bandwidth Availability and Bearer Size
Quotes vary based on:
- Required bandwidth: 100 Mbps vs 1 Gbps
- Bearer size: 1 Gbps bearer with 100 Mbps commit is costlier than a capped 100 Mbps line
A 1 Gbps bearer allows future upgrades but costs more upfront.
4. Service Level Agreements (SLAs)
Better SLAs mean higher prices:
- Fix times: 2-hour vs 8-hour response
- Uptime guarantees: 99.99% vs 99.9%
Higher-tier SLAs come with costs, especially for 24/7 support and proactive monitoring.
5. Contract Terms and Incentives
Longer contracts may:
- Waive installation fees
- Offer lower monthly rates
Shorter contracts mean flexibility but usually cost more.
| Term Length | Typical Monthly Cost | Installation Cost |
| 12 months | £350–£600 | Often £1,000–£3,000 |
| 36 months | £250–£400 | Often £0 |
6. Setup Costs and Surveys
Quotes may vary if:
- Civils work (digging) is required
- Extra hardware is needed on site
- Surveys uncover unexpected infrastructure needs
Always check whether the site survey is included and whether costs may increase post-survey.
7. Value-Added Services
Some providers include:
- Fully managed routers
- Backup connections
- Proactive 24/7 support
Others offer a “wires-only” service. The more value-added options included, the higher the monthly price.
8. Promotions and Reseller Margins
Resellers may:
- Mark up quotes for profit
- Offer volume discounts
- Apply time-limited promotions
A provider offering a special deal may undercut others temporarily. Always confirm if pricing is permanent or promotional.

Final Thoughts
Leased line quotes vary for good reason. A cheaper quote might mean fewer features, longer fix times, or reseller mark-ups. Always review the full picture—not just the price tag.
