In practice, duct
access is the right for one network operator to use another party’s underground ducts, conduits or trenches to install, operate and maintain its own cables or sub‑ducts, usually for a fee and on agreed technical and safety terms. It is a descriptive industry term rather than a standalone legal definition, but in telecoms it commonly arises under regulated “physical infrastructure access” (PIA) obligations or bespoke commercial agreements.
Key features include rights to survey, install and maintain equipment; capacity and quality standards; make‑ready works; restoration obligations; service levels; liability and indemnity; and price and dispute mechanisms. In the UK, Ofcom may impose PIA on providers with significant market power (for example, Openreach’s ducts and poles) under the Communications Act 2003, and broader rights to request access to physical infrastructure exist under the Communications (Access to Infrastructure) Regulations 2016. In Ireland, ComReg can impose equivalent access duties under the European Union (Electronic Communications Code) Regulations 2022, alongside cost‑reduction rules enabling access to physical infrastructure.
Usage and legal effect are broadly consistent across England & Wales, Scotland, Northern Ireland and Ireland, though the underlying land rights (for example, wayleaves/servitudes) and specific regulatory conditions vary by jurisdiction.
