For UK businesses that depend on fast, reliable, and symmetrical connectivity, business Ethernet represents the gold standard. Unlike consumer broadband — which is designed for domestic use and shared across your neighbourhood — business Ethernet delivers a dedicated, uncontended connection directly to your premises, backed by enterprise-grade service level agreements. Whether you’re running latency-sensitive cloud applications, hosting on-site servers, or connecting multiple offices over a wide-area network, Ethernet gives you the performance guarantees that standard broadband simply cannot match.
But the landscape of business Ethernet in the UK has changed dramatically. Where once the only option was a costly Ethernet Access Direct (EAD) circuit delivered over dedicated fibre, businesses today can choose from a range of bearer technologies — including the increasingly popular Ethernet over FTTP (EoFTTP), which delivers many of the same benefits at a fraction of the price. With Openreach, Virgin Media Business, CityFibre, and other alternative network providers all expanding their fibre footprints, UK businesses have more options, more competitive pricing, and faster installation timescales than ever before.
This guide breaks down everything you need to know about business Ethernet in 2026: the different product types, how they compare on speed, SLAs, and cost, what the ordering and installation process looks like, and how to choose the right circuit for your organisation.
What Is Business Ethernet?
At its core, business Ethernet is a dedicated data connectivity service that delivers symmetrical upload and download speeds over a fibre-optic connection to your premises. Unlike standard broadband — which shares bandwidth between multiple users on the same local exchange or cabinet — a business Ethernet circuit provides a guaranteed amount of bandwidth exclusively for your organisation.
The term “Ethernet” refers to the network protocol used to deliver the service, which is the same technology used in local area networks (LANs) inside offices. This means the connection integrates seamlessly with your internal network infrastructure — no protocol conversion, no bottlenecks at the handoff point, and no additional equipment beyond a Network Terminating Equipment (NTE) device installed at your premises.
Key Characteristics of Business Ethernet
- Symmetrical speeds — identical upload and download bandwidth, critical for cloud applications, video conferencing, VoIP, and data backup
- Uncontended bandwidth — the full circuit speed is available to your business at all times, regardless of what your neighbours are doing
- Guaranteed SLAs — contractual commitments on uptime, latency, jitter, and fault repair times, with financial penalties if breached
- Low latency — typically sub-5ms to the provider’s core network, essential for real-time applications
- Scalable — available from 10 Mbps right up to 10 Gbps, with the ability to upgrade without changing the physical circuit in many cases
If your business relies heavily on cloud-hosted applications (Microsoft 365, Salesforce, hosted VoIP, or cloud ERP), symmetrical upload speeds are just as important as download speeds. Standard broadband may offer 80 Mbps download but only 20 Mbps upload — a bottleneck that business Ethernet eliminates entirely.
EAD: Ethernet Access Direct
Ethernet Access Direct (EAD) is the premium business Ethernet product delivered by Openreach, BT’s network infrastructure arm. It is the traditional “gold standard” for dedicated connectivity in the UK and has been the backbone of business networking for over a decade.
How EAD Works
An EAD circuit provides a dedicated point-to-point fibre connection from your premises directly to a Point of Presence (PoP) or data centre operated by your chosen service provider. The fibre is not shared with anyone else — it is your dedicated physical link. This means your bandwidth is guaranteed 24/7, regardless of network congestion elsewhere.
EAD circuits are available in several speed tiers:
- EAD 100 — 100 Mbps symmetrical
- EAD 1000 — 1 Gbps symmetrical (also known as “GEA 1G” in some contexts)
- EAD 10000 — 10 Gbps symmetrical
Each tier can also be provisioned with lower bandwidth options on the same bearer. For example, you might install an EAD 1000 bearer but initially purchase 200 Mbps of bandwidth, with the option to upgrade to the full 1 Gbps later without any physical line changes.
Advantages of EAD
- Dedicated fibre — truly uncontended at the physical layer, not just at the service level
- Industry-leading SLAs — typically 99.95% uptime with 5–7 hour fault repair targets
- Proven reliability — mature technology with a decades-long track record in the UK
- Carrier-grade performance — sub-5ms latency to the provider PoP, near-zero jitter
- Resilience options — dual-path and diverse-route configurations available for mission-critical sites
Limitations of EAD
- Cost — significantly more expensive than alternative Ethernet products, with monthly rentals typically starting from £300+ for a 100 Mbps circuit
- Long lead times — installation can take 60–90 working days, sometimes longer if civil works (digging up roads or pavements) are required
- Excess construction charges (ECCs) — if new fibre needs to be laid to reach your premises, you may face one-off build costs running into thousands of pounds
EoFTTP: Ethernet over FTTP
Ethernet over FTTP (EoFTTP) is a newer Openreach product that delivers business-grade Ethernet services over the existing FTTP (Fibre to the Premises) network — the same full-fibre infrastructure used for consumer and business broadband. Launched to address the cost and lead-time limitations of EAD, EoFTTP has rapidly become one of the most compelling connectivity options for UK businesses.
How EoFTTP Works
Unlike EAD, which uses a dedicated point-to-point fibre, EoFTTP uses the GPON (Gigabit Passive Optical Network) architecture that underpins Openreach’s FTTP broadband network. While the underlying fibre is shared at the physical layer (via passive optical splitters), Openreach applies traffic prioritisation and dedicated bandwidth allocation at the service level to ensure your Ethernet traffic receives guaranteed performance.
EoFTTP is available at the following speed tiers:
- EoFTTP 100/100 — 100 Mbps symmetrical
- EoFTTP 160/160 — 160 Mbps symmetrical
- EoFTTP 330/330 — 330 Mbps symmetrical
- EoFTTP 500/500 — 500 Mbps symmetrical
- EoFTTP 1000/1000 — 1 Gbps symmetrical
Why EoFTTP Is a Game-Changer
The appeal of EoFTTP is straightforward: it delivers the majority of EAD’s benefits at 40–60% lower cost, with significantly shorter installation timescales. For many businesses, the slight reduction in SLA stringency compared to EAD is a worthwhile trade-off for the dramatic cost savings.
EoFTTP is only available at premises where Openreach FTTP infrastructure has already been deployed. As of early 2026, Openreach’s FTTP network reaches approximately 15 million UK premises, with a target of 25 million by the end of 2026. If your premises are not yet FTTP-enabled, EAD or an alternative network provider may be your only dedicated Ethernet option. Use the Openreach FTTP checker or ask Cloudswitched to run an availability check for your postcode.
Ethernet First Mile (EFM)
Ethernet First Mile (EFM) is an older business Ethernet product that delivers symmetrical bandwidth over bonded copper pairs — the same copper telephone lines used for ADSL broadband. Multiple copper pairs are bonded together to achieve higher speeds, typically up to 35 Mbps symmetrical.
EFM was historically a popular choice for businesses that needed guaranteed symmetrical bandwidth but could not justify the cost of EAD. However, with the rollout of FTTP and the availability of EoFTTP, EFM is now largely considered a legacy product. Openreach has stopped selling new EFM circuits in many exchange areas, and existing circuits will eventually be migrated as the copper network is retired.
If your business currently uses EFM, now is an excellent time to review your options. An EoFTTP circuit will typically deliver 3–10 times the bandwidth at a similar or lower monthly cost, with better SLAs and lower latency.

Speed Tiers: 100 Mbps to 10 Gbps
Choosing the right speed tier depends on your number of users, the applications you run, and your growth trajectory. Here is a practical guide to help you match bandwidth to business need.
Bandwidth Requirements by Use Case
| Speed Tier | Best Suited For | Typical User Count |
|---|---|---|
| 100 Mbps | Small offices running cloud apps, VoIP, email, and web browsing | 10–30 users |
| 200–330 Mbps | Medium offices with video conferencing, cloud CRM, and regular file transfers | 30–75 users |
| 500 Mbps | Larger offices or multi-site hubs with heavy cloud usage and backup traffic | 75–150 users |
| 1 Gbps | Head offices, data-intensive operations, on-site servers, large VoIP deployments | 150–500 users |
| 10 Gbps | Data centres, large enterprise campuses, ISPs, media production facilities | 500+ users or high-throughput workloads |
Bandwidth Consumption by Application
When calculating your bandwidth requirements, plan for peak usage, not average usage. If 50 staff join a company-wide video call at 9 AM while cloud backups are running, your circuit needs to handle that concurrent demand without degradation. As a rule of thumb, provision at least 50% more bandwidth than your calculated peak to allow for growth and headroom.
Openreach vs Alternative Network Providers
Openreach is the dominant infrastructure provider for business Ethernet in the UK, but it is far from the only option. A growing number of alternative network providers (alt-nets) now offer competitive or superior Ethernet services in many areas.
Openreach
As BT’s network arm, Openreach operates the largest fibre infrastructure in the UK. Most internet service providers (ISPs) and managed service providers resell Openreach connectivity, meaning you can buy EAD or EoFTTP from a wide range of suppliers, all delivered over the same underlying Openreach network. The advantage is near-universal coverage; the limitation is that pricing and lead times are set by Openreach, so there is relatively little variation between resellers on the wholesale cost.
CityFibre
CityFibre is the UK’s third-largest full-fibre platform, with coverage across over 60 cities and towns. They provide dedicated Ethernet circuits with competitive pricing, often undercutting Openreach EAD on like-for-like products. CityFibre circuits are particularly strong in urban areas where they have their own duct and fibre infrastructure, enabling faster installation and lower ECCs.
Virgin Media Business (VMO2)
Virgin Media Business operates an extensive cable and fibre network that covers large parts of the UK, particularly urban and suburban areas. Their Ethernet products are delivered over their own infrastructure, independently of Openreach. For businesses in Virgin Media’s footprint, this offers a genuinely diverse connectivity option — ideal for resilience when paired with an Openreach circuit.
neos Networks, Zayo, euNetworks, and Others
Several specialist providers focus on high-capacity Ethernet and dark fibre for enterprise and data centre connectivity. These providers are particularly relevant for businesses needing 1 Gbps and above, multi-site MPLS or SD-WAN solutions, or connections between data centres.

Ordering and Installation Process
Understanding the Ethernet installation journey helps you plan timescales and avoid costly surprises. Here is what to expect for each major product type.
EAD Installation Timeline
- Site survey and availability check (Day 1–5) — your provider submits an order to Openreach, who check whether existing fibre reaches your premises or whether new build is required
- Wayleave and planning (Days 5–20) — if civil works are needed, Openreach must obtain permission from landowners and local authorities to dig or install overhead cables
- Fibre installation (Days 20–60) — physical fibre is pulled from the nearest Openreach PoP to your building, with NTE installation inside your premises
- Circuit testing and handover (Days 60–75) — end-to-end testing of the circuit, followed by handover to your provider for service activation
- Service activation (Days 75–90) — your provider configures their network equipment and activates your Ethernet service
Total typical timescale: 60–90 working days (can extend to 120+ days if significant civil works are needed).
EoFTTP Installation Timeline
- Availability check (Day 1–2) — confirm FTTP is available at your premises via Openreach’s systems
- Order placement (Day 2–5) — your provider places the EoFTTP order with Openreach
- ONT installation (Days 5–20) — if FTTP is not already installed at the premises, an Openreach engineer installs the Optical Network Terminal (ONT)
- Service activation (Days 15–25) — the Ethernet service is provisioned over the FTTP connection and handed to your provider for activation
Total typical timescale: 15–30 working days (often faster if FTTP is already installed at the premises).

SLAs and Support
One of the primary reasons businesses invest in Ethernet over standard broadband is the contractual service level agreement (SLA). An SLA defines the minimum performance the provider guarantees, and what compensation you receive if they fail to deliver.
Key SLA Metrics
| SLA Metric | EAD (Typical) | EoFTTP (Typical) | Business Broadband |
|---|---|---|---|
| Availability (uptime) | 99.95% | 99.9% | No SLA |
| Fault repair target | 5–7 hours | 7–12 hours | Next business day (best effort) |
| Latency to provider PoP | <5 ms | <10 ms | No SLA |
| Jitter | <2 ms | <5 ms | No SLA |
| Packet loss | <0.1% | <0.1% | No SLA |
| Proactive monitoring | 24/7 NOC | 24/7 NOC | Rarely included |
| SLA credits | Yes — percentage of monthly rental | Yes — percentage of monthly rental | None |
For businesses running mission-critical applications — VoIP phone systems, EPOS terminals, real-time data replication, or cloud-hosted ERP — the difference between a 5-hour repair target and a “next business day” response can mean thousands of pounds in lost revenue. This is where Ethernet pays for itself many times over.
Enhanced Care Levels
Both Openreach EAD and EoFTTP circuits can be ordered with enhanced care levels that reduce fault repair targets further. The most common options are:
- Standard Care — fault repair within 40 hours (EAD: included by default on older products)
- Enhanced Care — fault repair target of 7 hours, available 24/7
- Premium Care — fault repair target of 5 hours, available 24/7, with proactive monitoring and priority engineer dispatch
Upgrading from standard to enhanced or premium care typically adds £30–£80 per month to the circuit rental, depending on the product and speed tier. For any business-critical circuit, this is money very well spent.
Pricing Comparison
Ethernet pricing in the UK varies significantly depending on the product type, speed tier, contract length, location, and provider. Here is a realistic pricing guide based on typical market rates in 2026.
| Product | Speed | Typical Monthly Rental | Typical Installation Cost | Contract Term |
|---|---|---|---|---|
| EoFTTP | 100 Mbps | £150 – £250 | £0 – £250 | 12–36 months |
| EoFTTP | 330 Mbps | £200 – £350 | £0 – £250 | 12–36 months |
| EoFTTP | 1 Gbps | £300 – £500 | £0 – £500 | 12–36 months |
| EAD | 100 Mbps | £300 – £500 | £1,000 – £5,000+ | 36 months |
| EAD | 1 Gbps | £500 – £900 | £2,000 – £10,000+ | 36 months |
| EAD | 10 Gbps | £1,500 – £3,000+ | £5,000 – £20,000+ | 36 months |
| EFM (legacy) | Up to 35 Mbps | £200 – £350 | £200 – £500 | 12–36 months |
3-Year Total Cost of Ownership: 100 Mbps Ethernet
As the numbers show, EoFTTP delivers significant savings over EAD while still providing guaranteed bandwidth and SLA protection that standard broadband cannot offer. For many UK businesses, EoFTTP occupies the ideal “sweet spot” between enterprise-grade performance and cost-effectiveness.
Use Cases: Which Ethernet Product Is Right for You?
The right Ethernet product depends on your business requirements, risk tolerance, and budget. Here are common scenarios and our recommendations.
Small to Medium Office (10–50 Users)
A professional services firm with 30 staff running Microsoft 365, a hosted VoIP phone system, and cloud-based accounting software. They need reliable, symmetrical connectivity but are budget-conscious.
Recommendation: EoFTTP 100–330 Mbps. Delivers ample bandwidth for all cloud applications and VoIP traffic, with an SLA that ensures problems are fixed within hours, not days. Monthly cost of £150–£350 is easily justified against the revenue impact of downtime.
Multi-Site Business with Hub-and-Spoke Network
A retail chain with 15 locations and a head office running centralised EPOS, stock management, and a private MPLS or SD-WAN network. Branch sites need reliable connectivity; the head office needs high bandwidth and maximum resilience.
Recommendation: EoFTTP 100–500 Mbps at branch sites, EAD 1 Gbps at head office. This hybrid approach puts premium connectivity where it matters most (the hub) while keeping branch costs manageable. Consider adding a secondary broadband connection at the head office for failover.
Data Centre or High-Throughput Facility
A SaaS company hosting production infrastructure in a co-location data centre, requiring ultra-low latency and high-capacity connectivity to multiple carrier networks.
Recommendation: EAD 10 Gbps or dark fibre. At this scale, the premium for dedicated fibre is a small percentage of overall infrastructure costs, and the performance guarantees are non-negotiable. Consider dual-path EAD for full resilience.
Startup or Growing Business
A technology startup with 8 staff today but planning to scale to 40+ within 18 months. They need flexibility to upgrade without contract penalties or re-installation.
Recommendation: EoFTTP 100 Mbps on a 12-month contract, with a plan to upgrade to 330 Mbps or 500 Mbps as headcount grows. EoFTTP’s speed upgrades can often be applied remotely without an engineer visit, making it ideal for fast-growing businesses.
Healthcare or Regulated Sector
An NHS trust or private healthcare provider running clinical applications, electronic patient records, and medical imaging systems that demand guaranteed low-latency connectivity with strict uptime requirements.
Recommendation: EAD 100 Mbps–1 Gbps with premium care SLA. Healthcare environments cannot tolerate connectivity interruptions that affect patient care. The 5-hour repair target and proactive monitoring of premium EAD provide the assurance these organisations require.
Making the Right Decision
Choosing between EAD, EoFTTP, and alternative Ethernet products is not a one-size-fits-all decision. The right answer depends on your specific combination of performance requirements, budget constraints, geographic location, and risk appetite. Here is a decision framework to guide your choice.
Choose EoFTTP If:
- Your premises are in an Openreach FTTP-enabled area
- You need up to 1 Gbps symmetrical bandwidth
- A 99.9% uptime SLA and 7–12 hour repair target are acceptable
- Budget is a significant factor and you want enterprise-grade connectivity without enterprise-grade pricing
- You need fast installation (under 30 days)
Choose EAD If:
- You need speeds above 1 Gbps (up to 10 Gbps)
- Your applications demand the absolute lowest latency and jitter
- A 99.95% uptime SLA and 5-hour repair target are essential for your operations
- You require a truly dedicated, uncontended physical fibre connection
- You are connecting to a data centre or building a carrier-grade network
Consider an Alt-Net Provider If:
- Openreach pricing or lead times are prohibitive in your area
- You need a diverse route for resilience alongside an existing Openreach circuit
- CityFibre, Virgin Media Business, or another provider has infrastructure directly serving your premises
