At present, fixed line to mobile calls constitute one third of all business telephone costs. These costs will drop by 25-30 per cent under BT, meaning an 8-10 per cent overall saving.
These measures will also allow BT Business plan customers to opt for a 30p cap on calls to mobiles lasting up to an hour.
Craig Rowland, managing director of BT Business, said: “This is the end of expensive business calls. The combination of the 10p cap for inland calls, the 20p cap for most international calls and now the 30p cap for calls to mobile phones, will give customers the peace of mind that they can talk for as long as they want without running up a large bill.
With these caps put in place business customers will not pay on average for the 64 per cent of the time spent on the phone to mobiles.
These reduced rates were introduced on September 1 for all customers and the 30p cap will be introduced on the same date for business plan customers spending over £500 per year with BT. BT Business Plan customers spending less than £500 per year will be able to opt into the 30p cap from October 1.
The news may be seen as a response to falling pre-tax profits for the tele-communications giant.
