Full Fibre (FTTP) Broadband 2026: UK Coverage, Speeds, and Provider Comparison

Older FTTC technology delivers asymmetrical speeds: impressive downloads (67Mbps) but constrained uploads (6–18Mbps). This asymmetry creates professional bottlenecks for anyone creating or broadcasting content.

Casual Zoom and Teams video conferencing require just 3–4Mbps upload—FTTC handles this easily. However, streaming 1080p60fps to Twitch demands 8–10Mbps upload, leaving marginal headroom on FTTC's 18Mbps cap. Add simultaneous gaming (2Mbps), Discord communication (2Mbps), and Windows background updates (1–2Mbps), and you're consuming 13–18Mbps of available 18Mbps. Peak CPU load during intense gameplay spikes demand higher, throttling your stream bitrate—visible quality degradation your audience sees.

FTTP's 150Mbps symmetrical upload changes everything. That same workflow (12–15Mbps demand) uses just 10% of available capacity, leaving 135Mbps headroom for any simultaneous activity without throttling.

Professional content creators uploading edited 4K video files experience time-saving transformations. A 100GB 4K file upload takes 12+ hours on FTTC's 18Mbps connection—forcing overnight uploads that delay client deliverables. The same file uploads in 90 minutes on FTTP's 150Mbps symmetrical connection, enabling same-day turnaround for professional workflows.

For 4K30fps streaming (20–30Mbps upload requirement), FTTC becomes impossible—the 18Mbps upload can't sustain the bitrate. FTTP 150Mbps handles 4K streaming comfortably with room to spare.

The verdict is straightforward: Casual users streaming Netflix or attending Zoom calls don't benefit from FTTP's symmetrical uploads—FTTC's 18Mbps upload more than adequate. Serious streamers broadcasting whilst gaming simultaneously require FTTP 150Mbps minimum to avoid throttling. Professional creators handling 4K editing and large file uploads depend on FTTP 300–500Mbps for reasonable workflow turnaround that doesn't consume entire evenings uploading files.
