BT's new boss Ben Verwaayen hopes to kick-start the broadband revolution in the UK by making high-speed net access more affordable.
The Dutchman, who took over as chief executive last week, plans to outline "substantial" reductions to wholesale broadband charges in a fortnight.
BT sells space on its network to rival service providers wanting to supply faster net access to homes and businesses.
Cuts from the current £30 a month per line should help ISPs lower their own prices, reductions likely to be mirrored by BT's own Internet arm BTopenworld.
Mr Verwaayen, one of only a few foreign bosses in charge of a FTSE 100 firm, said: "We will have a substantial reduction in cost on a wholesale basis.
"I believe strongly that a commitment from BT to broadband will give an important impulse to the market."
The comments will be a lift to the Government, which wants broadband take-up to increase markedly in the UK and approach levels seen elsewhere in Europe.
