For most new broadband connections delivered over the Openreach network, the installation process typically takes between 10 and 15 working days from the point an order is confirmed, although this can vary depending on the type of service and the readiness of the existing line. Standard business broadband or fibre-to-the-cabinet (FTTC) services often fall towards the shorter end of this range when an active line is already present and no engineering visit inside the premises is required. In such cases, the work is largely completed at the local exchange or street cabinet, and the service can go live once the agreed activation date is reached and the router is correctly connected on site.
Where a new line is required, or where full fibre (FTTP) is being installed for the first time, the timeline can extend to several weeks, particularly if additional external engineering work, wayleaves, or access to shared areas are needed. Openreach will usually provide a provisional installation date soon after the order is placed, and this may be refined following preliminary checks or a survey. Businesses should also factor in potential delays caused by engineer availability, complex building layouts, or the need to coordinate access with landlords or facilities managers. Planning ahead, providing accurate site information, and being flexible with appointment slots can all help to keep the installation on schedule and minimise disruption to day-to-day operations.
For a straightforward transfer of an existing Openreach-based service, the typical lead time is around 10 working days. This covers the minimum regulatory notice period and allows Openreach to schedule any necessary work at the exchange or cabinet. In many such cases, no engineer visit is required inside the premises, and the changeover happens remotely on the agreed activation date.
Where a new line must be installed, an engineer visit is usually required, which can extend the process to 10–15 working days or more, depending on engineer availability. If external work is needed, such as running new cabling from the street, the appointment may be split across multiple visits, adding further time.
Full fibre (FTTP) installations can take longer, particularly in areas that have not previously been served or where wayleaves are required. Here, timescales can range from a couple of weeks to several months for complex sites, especially multi-tenant offices or business parks.
