This on-net data file contains a list of addresses where our network records show we have existing on-net presence i.e. where Openreach fibre infrastructure already exists at the location. Having existing fibre infrastructure, typically means we’re able to deliver Ethernet connectivity within 20 working days. Actual delivery timescales will be confirmed, on a per circuit basis, through our standard Ethernet order process.

The on-net data file below lists postcodes within most metro areas, including the Central London Area (CLA), where our records show we have fibre capacity within a given building. Central London Area is the area consisting of the postal sectors set out in Schedule 2 of Annex 35 to Ofcom’s BCMR Statement of 28 April 2016. Please note some address points do not include a building number, however we have still included these for completeness. We aim to refresh the list at least every six months.

We’re making this data available to CPs who intend to purchase wholesale Ethernet services from us, on the terms and conditions of data usage applicable to the existing Openreach Infrastructure Discovery map tool.
