The Openreach Fibre Availability Checker is a straightforward online tool that allows you to see what fixed-line broadband technologies are available at a specific address or telephone line. By entering either your business landline number or full postcode and address, you can quickly identify whether fibre-to-the-cabinet (FTTC), fibre-to-the-premises (FTTP), or only standard copper-based services are currently available. The checker draws on Openreach’s network data, which underpins the majority of UK business broadband and telephony services, so it is one of the most reliable indicators of what services can realistically be ordered at your location. For organisations planning upgrades, office moves or new sites, this information is essential for understanding what connectivity options you can expect before committing to contracts or premises.
To use the Openreach Fibre Availability Checker, visit the Openreach website and locate the broadband or fibre checker tool. You will usually be given the option to search by phone number or by address. If you have an existing fixed line, enter that number and follow the prompts; this typically gives the most accurate result. If not, use the address option, ensuring you select the exact premises from the list provided. The checker will then display the types of broadband available, estimated speeds, and any notes about planned upgrades. While you cannot order services directly from Openreach, the results provide a clear view of what fibre-based products service providers can offer at your business location.
To begin, open a web browser and go to the Openreach website, then navigate to the broadband or fibre availability section. Choose whether you want to search by landline number or by address. Using a landline number usually gives the most precise result, as it is tied directly to a specific line on the network.
If you search by address, enter your postcode first, then select your building and, where applicable, your unit or suite from the dropdown list. Check that the address you choose exactly matches your premises, as neighbouring units may have different availability. Once submitted, the checker will query the Openreach database and return the technologies and estimated speeds available.
Review the results carefully. Look for indicators such as FTTC, FTTP or Gfast, along with maximum download and upload speeds. If fibre is not yet available, the checker may show whether upgrades are planned, helping you plan future connectivity and discuss alternatives with your chosen service provider.
