Advantages and Disadvantages of FTTP for Business

What Is FTTP and How Does It Differ From FTTC?

FTTP — Fibre to the Premises — runs a glass fibre cable from the exchange or local distribution point all the way to the building. There is no copper in the local loop, the stretch of network between the street cabinet and your premises. That single design choice removes the bottleneck that holds copper-based services back.

FTTC (Fibre to the Cabinet) runs fibre only as far as the street cabinet, then falls back to existing copper telephone wire for the final hop. The copper local loop is what limits FTTC performance. FTTP eliminates it entirely, which is why the two technologies behave so differently in real use. If you are weighing your options across both products, our business broadband guidance walks through what each delivers for a working office.

What Are the Advantages of FTTP for Business?

FTTP gives a business faster uploads, steadier performance, lower latency and an infrastructure base that matches where UK networks are heading. For cloud-first teams running backups, video calls and hosted apps, those gains are immediate and measurable rather than theoretical.

Faster Upload Speeds

Upload speed is the single biggest practical win. FTTC typically delivers 10–20Mbps upstream. FTTP delivers upstream speeds from 50Mbps to 1Gbps depending on the product tier. For cloud backups, video conferencing, hosted applications and client file sharing, that gap changes how the working day actually feels.

More Consistent Performance

FTTP performance barely cares where you sit relative to network infrastructure. An FTTC line a long way from the cabinet might manage only 20–30Mbps download despite being sold as an "up to 80Mbps" product. FTTP holds its speed regardless of premises location, so what you buy is far closer to what you get.

Lower Latency

Full fibre carries lower round-trip latency than FTTC. Typical FTTC latency runs 10–25ms; FTTP latency typically sits at 5–10ms. For VoIP calls and other real-time applications, lower latency means less audio delay and a more responsive connection. If voice quality is a priority, our business VoIP services explain how connectivity and call performance fit together.

Future-Proof Infrastructure

The UK's analogue phone network (PSTN) is being retired and migrated to digital, a transition overseen by the regulator (Ofcom). FTTP is the baseline infrastructure for converged voice and data once copper goes. Moving to FTTP now aligns your business with the direction of UK network investment rather than against it.

Competitive Pricing

FTTP pricing has fallen sharply as rollout has accelerated. A 1Gbps business FTTP connection is now available from roughly £60–£120/month in many UK areas — comparable to, or cheaper than, 80Mbps FTTC products cost only a few years ago.

What Are the Disadvantages of FTTP for Business?

The drawbacks are about guarantees and reach, not raw speed. FTTP is not yet available everywhere, carries no formal SLA, shares capacity with other users, and takes weeks to install. None of these are dealbreakers for most offices, but they matter where downtime has a price.

Availability Is Not Universal

Coverage is the biggest limitation. Openreach FTTP has passed over 16 million UK premises as of 2026, yet many addresses — especially in rural areas and smaller towns — are still unserved. Ofcom tracks national full-fibre reach in its Connected Nations programme (Ofcom Connected Nations). If FTTP has not reached you, no budget makes it appear.

No Formal SLA

FTTP, like all broadband, is a best-efforts service. There is no guaranteed uptime commitment in the sense a leased line provides. Standard business FTTP offers next-business-day fault response, not the rapid repair guarantee that comes with a dedicated circuit. Where downtime carries real financial or operational cost, that distinction is the whole argument.

Contended (Shared) Infrastructure

FTTP is shared infrastructure, so bandwidth is contended between multiple users. Contention ratios are generally far lower than FTTC, meaning less slowdown at peak times — but it is not the dedicated, uncontended capacity of a leased line. During congestion events, FTTP speeds can dip below the tier you purchased.

Asymmetric Speeds on Some Products

Depending on provider and product, FTTP upload speed can be lower than download. Most business FTTP products are symmetric or near-symmetric, but confirm this rather than assume it — the headline download figure does not always tell you the upstream story.

Installation Lead Times

A new FTTP connection needs a physical install visit, typically 2–4 weeks from order. If you are planning an office move or need connectivity urgently, build that lead time into the plan rather than discovering it the week before go-live.

FTTP vs Leased Line: Which Should a Business Choose?

For most SMEs, FTTP is a clear step up from FTTC and represents strong value. Where internet reliability is genuinely mission-critical, a business leased line — from around £69/month — gives dedicated, uncontended bandwidth with a contractual SLA that FTTP cannot match.
