W1C's standout feature is full fibre availability at 88% of its 115 postcodes across central Westminster. Full fibre and gigabit both reach 88%, indicating direct fibre-to-premises connection enabling maximum bandwidth and future-proofing for residents and offices. Superfast reaches 99.7%, essentially universal. The speed distribution reflects this fibre advantage: 88% of postcodes sustain gigabit speeds through full fibre, just 1.7% are limited to 30 to 300 Mbps superfast, and only 0.3% fall below superfast. No postcodes miss the universal service obligation. For businesses and residents in W1C, full fibre gigabit is the norm rather than the exception. Offices can rely on consistent, symmetric upload and download capacity for video production, cloud services and real-time collaboration. The 1.7% on superfast still enjoy fast, reliable service suitable for most household tasks.
