Cable company Telewest is to offer the UK's first three megabit broadband service.
In a shake-up of existing services it will speed up all its broadband products by 50% for free.
Rival cable net provider NTL is also doubling the speed of its broadband services at no extra cost.
It is part of a fierce ongoing battle between internet service providers to win customers to their high-speed net connections.
Telewest will upgrade services at the end of May.
The three megabit service will offer speeds up to 60 times faster than traditional dial-up access.
People on the 512Kbps Blueyonder service will see speed increase to 750Kb.
