On-network churn across the whole business fell to 1.2%, its lowest level since 2004, but a shift of existing customers to lower priced packages contributed to a decrease in average revenue per user from £42.24 in the previous quarter to £41.91.
Revenues were down 2% year on year to £1bn but the company narrowed its net loss from £120.3m a year ago to £104.4m.
The number of subscribers with Virgin's V+ digital video recorder grew 101,800 during the quarter to 364,200.
Neil Berkett, chief executive of Virgin Media, said: "Our first quarter results represent another solid operational performance. In particular, churn continued to decline, reflecting the emphasis that we have placed on this area."
