Business Ethernet: Dedicated Circuits for UK Companies
Ethernet is the procurement word for what a leased line delivers: a dedicated, symmetric, SLA-backed circuit into your premises. 100Mbps from £69/month, 1Gbps from £129 — specification-led, quoted per address across every carrier that reaches you.
Business ethernet is a dedicated, symmetric, uncontended data circuit delivered into your premises over fibre — in UK procurement it is the same product as an ethernet leased line or dedicated internet access. AMVIA delivers business ethernet from £69/month for 100Mbps and £129/month for 1Gbps on 36-month terms in well-served areas, SLA-backed (typically 99.99% uptime), quoted per address across Openreach, CityFibre, Virgin and route-dependent carriers.
Ethernet, leased line, DIA: one product, three names
If you're comparing quotes that variously say “business ethernet”, “ethernet leased line” and “dedicated internet access”, compare specifications, not names — they describe the same thing: a point-to-point or internet-connected fibre circuit reserved for your business, symmetric at every tier, uncontended by definition, and sold with an SLA. The vocabulary varies by carrier heritage; the engineering doesn't. Our dedicated internet access page covers the internet-facing product in depth, and the pricing page publishes the per-tier floors most providers hide behind quote forms.
Specification checklist for procurement
Six lines that belong on any ethernet RFQ, in the order they decide the outcome: bearer and service speed (specify both — 200Mbps on a 1Gb bearer beats 200Mbps on a 200Mb bearer for anyone growing); contention (must be 1:1 — anything else is broadband wearing a suit); symmetry (upload equals download, stated); SLA (uptime target, fix time, and the service credits that make both mean something); diversity options (second circuit on a separate route, or 4G/5G backup, if downtime is existential); and excess construction charges (confirmed by survey before signature, never after). A quote that goes quiet on any of these is telling you something.
What about EFM and EoFTTC?
Ethernet in the First Mile (bonded copper pairs) and Ethernet over FTTC had their era when full fibre was scarce: real SLAs at sub-fibre prices. In 2026 that era is closing — copper is being retired, speeds are capped, and the price gap to true fibre ethernet has narrowed to the point where we rarely recommend either except as a stopgap on genuinely hard-to-reach sites. If a provider leads with EFM in 2026, ask them why — and then ask us to check which fibre routes actually reach your postcode.
Pricing
From £69/month for 100Mbps, £129/month for 1Gbps, £349/month for 10Gbps and £1,999/month for 100Gbps on 36-month terms in well-served areas; installation typically £500–£2,000 depending on the civil works your address needs, confirmed by survey. Every figure is a published floor on a spec-dependent range — the exact number is a per-address fact, and we return it within 24 hours, carrier-compared.
The specification, up front
Ethernet variants, decoded
Procurement vocabulary differs; the products underneath are a short list.
Fibre ethernet (ethernet leased line)
Full fibre to your premises on a 100Mb–100Gb bearer. The default for every new circuit — everything else on this list is a fallback or a special case.
EoFTTC
Ethernet over FTTC: fibre to the cabinet, ethernet service over the last copper stretch. Cheaper, speed-limited, useful only where full fibre construction is uneconomic.
EFM — ethernet in the first mile
Ethernet over bonded copper pairs. A legacy product from before fibre coverage widened — still quoted occasionally, rarely the right answer in 2026, and copper's retirement is against it.
Dark fibre
The unlit fibre itself, for organisations running their own optical equipment — a different procurement conversation entirely.
Bearer vs service speed
Buy the service speed you need on the bearer you'll grow into: a 200Mbps service on a 1Gb bearer upgrades by config change, not construction.
The SLA
Uptime targets (typically 99.99%) with defined fix times and service credits — the line that separates ethernet products from any broadband product.
Order to live circuit
Ethernet installs are construction projects with a network at the end. We manage all of it.
Route check & quote
Every carrier reaching your postcode compared — Openreach, CityFibre, Virgin, plus Zayo, Colt and regional networks where on-net. Exact pricing within 24 hours.
Survey
The carrier surveys the route to your premises and confirms any excess construction charges before you commit — no surprises after signature.
Build & install
Civils where needed, fibre pulled, hand-off installed. Lead times vary by route complexity; we chase the carrier so you don't have to.
Live, monitored, SLA-backed
Router configured, circuit monitored proactively, faults worked to the SLA clock — with 4G/5G backup and diverse secondary circuits available where uptime is existential.
Why buy ethernet through AMVIA
Carrier-independent quoting with security-first delivery.
Every carrier, one quote
The cheapest correct answer is usually about which network is already in your street — we check them all rather than reselling one.
Secure at the edge
Circuits delivered by a provider that also runs managed firewalls and holds Cyber Essentials Plus — the hand-off is configured like infrastructure, not left at defaults.
Published SLAs, UK support
Sheffield-based engineers, defined fix times, service credits — in writing.
Multi-site ready
Ethernet everywhere, SD-WAN over the top, one provider accountable for the lot.

Business ethernet questions
Yes. Business ethernet, ethernet leased line, dedicated leased line and dedicated internet access all describe the same product: a fibre circuit reserved for one business, symmetric and uncontended, with an SLA. The name varies by seller; the specification is what to compare.
From £69/month for 100Mbps, £129/month for 1Gbps and £349/month for 10Gbps on 36-month terms in well-served areas, with installation typically £500–£2,000 depending on address. Prices are per-postcode floors — carrier competition on your street decides how close to them you land.
The bearer is the physical capacity of the circuit; the service speed is what you pay to use. A 200Mbps service on a 1Gb bearer upgrades to 500Mbps or 1Gbps by configuration change — the same upgrade on a 200Mb bearer means new installation. Growing businesses should almost always buy the bigger bearer.
Rarely. EFM runs over copper pairs that are being retired, its speeds are capped far below fibre, and fibre ethernet prices have fallen to the point where the saving seldom justifies the ceiling. It survives as a stopgap for genuinely hard-to-reach sites — and even there, checking every fibre route first is the right move.
It depends on the route: premises near existing carrier fibre can be weeks; sites needing new construction, wayleaves or road crossings take longer. The survey stage tells you honestly before you commit, and we manage the carrier throughout — including escalations when a build slips.
