There were approximately 18.4 million fixed broadband lines in the UK at the end of Q4 2009 including those used by small and medium enterprises (SMEs)

Subscriber growth over the past year has continued to drop but the rate of decline has slowed to the lowest ever. Year-on-year subscriber growth in Q4 was 5.7%, only slightly down on Q3

Looking at net additions, Q4 saw the strongest sequential growth in percentage terms since the early days of UK broadband, with growth of 54% compared to 10% in Q4 2008. The leap in Q4 2009 was from a relatively low base, but even in absolute terms, the sequential increase in net adds of 111k was the highest since Q3 2004

O2’s plan to launch competitively-priced ‘home phone’ offers in March should help sustain its current growth in fixed broadband, but is unlikely on its own to transform O2 into a significant player in UK fixed telecoms

The company’s fixed line foray is unlikely to reduce its mobile churn significantly, but nor does it look likely to increase it, with any residual net effect muted by the relatively small scale of O2’s fixed business

Demand for residential fixed telephony is declining gradually, and O2’s play is likely to make life more difficult for some established players, notably TTG, which is relatively dependent on demand from more price-sensitive customers
