BT to hit millions with New Year price rise of up to 6.5pc The increases will also trigger concerns that BT's ten million customers are having to foot the bill for its unprecedented investment in sports broadcasting. BT has spent around £1bn in picking up the rights for live Premiership football and rugby games for its flagship BT Sport venture, designed to rival Sky. The group has signed up star presenters and pundits such as Clare Balding and Rio Ferdinand. BT insisted earlier this summer that BT Sport would be "free or charge" to existing BT broadband customers. So far around a million have opted to receive the sports channels. The price changes detailed by BT revealed that its standard line rental charge will rise from £15.45 to £15.99 a month. BT's unlimited anytime call package, and its unlimited evening and weekend call plan, will remain unchanged. But customers on its unlimited anytime plus, unlimited anytime and mobile, and unlimited anytime plan will suffer increases of up to 6.4 per cent. BT 1571 will now cost £1.75 a month, while the price of other 'Calling Features' will rise by 6.5 per cent. Anonymous Call Reject, used by households to combat nuisance or cold calls, will up to £4.75 a month. Separate figures on Friday showed complaints about BT's broadband and TV service were on the rise. Ofcom said that BT broadband "generated complaints in excess" of the industry average, at 0.28 for every 1,000 customers, four times as many as Virgin Media. Complaints about BT's TV service were six times the industry average.
