Dedicated Internet Access (DIA) for UK Businesses

DIA sits at the heart of our business leased lines range. If you are still weighing the basics, start with what a leased line is before you read on.

What is dedicated internet access?

Dedicated internet access is a private fibre circuit that belongs to your business alone, with a 1:1 contention ratio and matching upload and download speeds. No other organisation shares the line, so performance does not sag at peak times. Every DIA circuit ships with a service level agreement that pays out if uptime targets are missed.

That uncontended design is the whole point. A standard broadband connection is sold many times over on the same exchange; a DIA circuit is sold once, to you. The result is predictable latency, predictable throughput, and a contract that holds the carrier financially accountable.

• Uncontended (1:1): the full bandwidth is yours at all hours
• Symmetric: identical upload and download speeds
• SLA-backed: financial credits when the provider misses targets
• Scalable: speeds from 10 Mbps to 10 Gbps on the same circuit type

How does AMVIA deliver your dedicated connection?

AMVIA manages the whole DIA lifecycle: survey, carrier procurement, install, and 24/7 monitoring. We hold the carrier relationship so you deal with one accountable provider, not three. Critical issues are responded to within one hour, with a named engineer assigned to your circuit.

1. Site survey and pricing — we check carrier availability at your postcode and quote across multiple providers to find the best fit. 2. Circuit provisioning — we order and project-manage the dedicated fibre circuit, keeping you updated through every carrier milestone. 3. Install and testing — engineers fit the circuit and CPE, then run throughput and latency tests to confirm the SLA is met on day one. 4. Monitoring and support — round-the-clock circuit monitoring with proactive alerting and direct escalation to the carrier on your behalf.

For sites that need resilience, pair DIA with backup connectivity so a single fibre fault never takes you offline.

DIA vs business broadband: what's the real difference?

Dedicated internet access guarantees the speed you pay for; broadband does not. Broadband contends bandwidth across many users and offers upload speeds far below download. DIA gives you symmetric, uncontended throughput with an SLA — the standard a business running cloud platforms and VoIP actually needs.

For context, the UK average broadband download speed is around 69.4 Mbps (Ofcom Connected Nations 2024). A DIA circuit delivers its rated speed both ways, every hour, regardless of how busy the local exchange gets.

Why do UK SMEs need dedicated internet access?

UK businesses now run on cloud platforms — Microsoft 365, hosted servers, VoIP, video — and every one of those depends on reliable upload as much as download. When a shared broadband line slows at 3pm, calls drop and backups stall. DIA removes that risk with guaranteed, symmetric bandwidth.

The wider network is shifting too: copper-based phone services are being switched off as the UK moves to all-IP connectivity (Ofcom PSTN switch-off guidance). A dedicated fibre circuit is the dependable foundation for that move, and it pairs naturally with SD-WAN connectivity when you scale across sites.

• Cloud backups and large file transfers finish on time, both directions
• VoIP and video conferencing stay clear under load
• Latency-sensitive apps behave predictably for every user
• A financial SLA gives you recourse when something breaks

How much does dedicated internet access cost?

AMVIA dedicated internet access starts from £69 per month for a 100 Mbps circuit, with speeds available from 10 Mbps up to 10 Gbps. Price depends on the speed you need and how far existing fibre reaches your premises. Where new fibre is required, civils work can affect both cost and lead time.

Running several locations? Our multi-site connectivity options bring every office onto one managed network, and leased line security hardens the circuit against threats.

How does AMVIA support your circuit after install?

Support does not stop at handover. AMVIA monitors every DIA circuit 24/7, responds to critical issues within one hour, and escalates faults straight to the carrier so you do not have to chase. You get a named account team that already knows your environment.

AMVIA holds Cyber Essentials Plus certification and Microsoft Solutions Partner status, and we manage IT and connectivity for over 1,200 UK businesses across legal, finance, healthcare, and professional services. One provider, security-first, Microsoft-certified.
