TalkTalk follows BT by raising line rental charges
TalkTalk has said it will increase its monthly line rental charge to £13.80 from October.
The 9.5% rise - which will add £14 to customers' annual bills - follows a 5% increase in line rental and call charges announced by BT last week.
TalkTalk said it also offers the option of an annual upfront charge equivalent to £9.50 per month, although it only applies to customers taking broadband.
The new standard rate is still less than BT's monthly charge of £14.60.
However, BT has promised to freeze its prices until 2013.
