• Fiber-to-the-home: symmetric by design, lowest jitter, and the most reliable under real-world load
• Coax, copper, and fixed-wireless: competitive download figures, but upload and peak-time performance vary by neighborhood and time of day
• What "good" looks like: a wired test in the 80–95% range of your advertised speed, with upload in the same ballpark your plan promises

ISPs at a glance

Measured speeds are wired-test ranges observed across consumer plans; actual figures depend on plan tier, address, and time of day. Always check each ISP's address-level availability tool for accurate plan and pricing information.

Speed Test Tips for London Residents

• Use Ethernet for the true line speed: even a modern Wi-Fi 6 router can cap or inflate results depending on distance, interference, and channel width
• Test morning and evening separately: ISP networks are provisioned for average load, not peak — prime-time slowdowns are the most telling metric
• Track upload as carefully as download: a "fast" line with slow upload will still drop video calls and stall file backups
• Record the minimum across a burst of tests: a single high number is easy to catch; what matters is the floor your connection hits under real conditions
