Openreach fibre broadband for business typically delivers download speeds ranging from around 40 Mbps on entry-level fibre-to-the-cabinet (FTTC) services, up to 1 Gbps and beyond on full fibre-to-the-premises (FTTP) connections. The speed you can expect will depend on the specific product available at your address, the quality of your internal network, and how many users and devices are sharing the connection. For many small and medium-sized businesses, a 40–80 Mbps FTTC service can comfortably support email, web browsing, cloud applications, and VoIP calls, provided usage is moderate and not heavily reliant on large file transfers or high-definition video conferencing.
For organisations with more demanding requirements, such as multiple cloud-based systems, frequent video meetings, remote access for staff, or large data backups, full fibre (FTTP) services of 160 Mbps, 330 Mbps, 500 Mbps or 1 Gbps are more appropriate. These higher-speed options provide greater headroom at busy times, reduce the risk of congestion, and offer significantly improved upload speeds compared with older copper-based services. As a general guide, a small office of up to 10 users may be well served by 80–160 Mbps, while larger teams, multi-site operations, or data-heavy environments will benefit from 330 Mbps and above. Choosing the right Openreach fibre speed is about matching available products to your current and future usage patterns.
Openreach FTTC (often marketed as “Superfast Fibre”) typically offers download speeds of around 40/10 Mbps or 80/20 Mbps (download/upload). These speeds are usually sufficient for smaller offices using email, web-based tools, basic cloud services, and a few concurrent VoIP calls. However, performance can vary slightly depending on your distance from the street cabinet and the quality of the copper line.
Openreach FTTP (“Full Fibre”) removes the copper element and delivers fibre directly to your premises, enabling much higher and more consistent speeds. Common business-grade FTTP profiles include 160/30 Mbps, 330/50 Mbps, 500/75 Mbps and 1000/115 Mbps. These are well suited to businesses running multiple cloud platforms, high-definition video conferencing, or regular off-site backups.
When planning, consider both download and upload needs, the number of simultaneous users, and any growth expected over the contract term. It is often more cost-effective to choose a slightly higher speed tier than you currently require, to accommodate new applications, additional staff, or increased reliance on cloud services without needing an early upgrade.
