Wired Telecommunications Carriers in the UK Industry Data and Analysis
Over the five years through 2025-26, wired telecommunications carriers' revenue is set to contract at a compound annual rate of 3.5% to £14.4 billion. The slump in revenue has been driven by a drop in landline use, cable TV subscriptions, intensifying competition among providers, stimulating price reductions and the shift towards wireless connections as they improve in speed. As consumers shifted to more readily available wireless options, revenue from traditional wired services took a hit. Alongside this, the Local Loop Unbundling has made it easier for new entrants to the market, intensifying competition for established carriers. Nevertheless, demand for fast, reliable connections and expanding full-fibre network services has kept demand fairly strong.
