Broadband Speed Guide

A practical guide to broadband speeds, connection types and choosing an appropriate package.

Headline speed is only one part of the experience

Broadband packages are usually compared by download speed, but upload speed, latency, jitter, Wi-Fi coverage and congestion also affect how a connection feels. A household that streams on several televisions while people work from home needs more headroom than one person browsing and checking email.

Common connection types

ADSL uses copper telephone lines and is generally the slowest fixed-line option. Fibre-to-the-cabinet still uses copper for the final section. Full fibre connects the premises using fibre and can provide higher, more consistent speeds. Cable and fixed wireless services have different performance characteristics.

Choosing a package

Typical useSuggested capacity
Browsing and email10 Mbps+
HD streaming and calls30–50 Mbps+
4K streaming and busy homes100 Mbps+
Heavy downloads and creators300 Mbps+ with strong upload

These are broad guides rather than guarantees. Count simultaneous users and choose enough spare capacity for peaks.
