The Universal Service Obligation (USO) for Broadband (323 KB , PDF)
The Universal Service Obligation (USO) for broadband is a UK-wide measure intended as a “safety net” to deliver broadband to those premises that do not have access to a decent and affordable connection.
The Government have defined a decent connection as one that can deliver 10 megabits per second (Mbps) download speed and 1 Mbps upload speed (along with other defined quality parameters). Ofcom has defined an affordable connection as one that costs less than £45 per month.
The USO provides a legal right to request a decent broadband connection, up to a cost threshold of £3,400 per premises.
BT (and KCOM in Hull) are the Universal Service Providers responsible for fulfilling requests from eligible consumers.
Residents and businesses are eligible for the USO if:
As of September 2021, Ofcom estimated around 123,000 premises UK-wide (0.4%) did not have access to a decent broadband connection. These premises are largely in remote, rural areas. Figures for individual constituencies can be found our our broadband speeds data dashboard.
The USO opened for requests on 20 March 2020. Requests must be made through BT (or KCOM in Hull).
BT’s website on the USO includes further information and an eligibility postcode-checker. KCOM does not expect to have any premises eligible in their area due to the reach of their existing network.
Ofcom’s FAQ page on the USO: Your right to request a decent broadband service: What you need to know (20 March 2020) provides further information and contact details.
Any technology capable of delivering the minimum technical USO standards could be considered to deliver connections, including mobile broadband. In practice, most connections under the USO are likely to use full-fibre or fibre-to-the-cabinet technology.
Depending on the technology used, some consumers may receive a higher quality connection than the minimum standards.
Ofcom reported that BT received just under 1,350 USO orders up to 14 October 2021. These orders will lead to full-fibre connections being built that can serve just under 6,500 premises.
Where BT estimate that the cost of connecting a premises under the USO would be more than £3,400 per premises, customers have the option of paying the excess costs.
Following concerns about the number of quotes that were falling above the cost threshold, Ofcom opened an investigation into how BT was calculating costs in July 2021. In response, BT agreed to change its method for calculating costs. The changes relate to how the cost of connecting a particular premises within a cluster of premises is calculated and shared.
Even with these changes Ofcom says there remains a “small but significant” number of premises for which the costs of building a connection are very high, mostly in remote rural areas. Following a call for evidence on connecting ‘very hard to reach’ premises’ in 2021, the Government said it would set out proposals for addressing connectivity challenges to these premises later in 2022.
