Virgin Media is to put up the price of its broadband-only services - which are taken without a landline - in the autumn.
The cable provider is increasing the cost of standalone broadband by £1.50 per month on October 1st, following a £2.50 per month hike 12 months earlier.
At present, Virgin Media's standalone broadband deals are priced at £26.50 per month.
Virgin Media is able to deliver broadband services without a landline because it operates its own cable network, rather than using BT's telecoms infrastructure.
Virgin's network - which is largely urban-based - reaches 12.5 million premises in total, with 4.4 million customers taking services from the firm.
Joe Lathan, Director of Broadband at Virgin Media, told TechweekEurope that the company is carrying out a review of the services it offers.
As part of this, the company is changing the price of taking broadband in a standalone deal.
But despite the latest hike, Mr Lathan claimed his company offers "unbeatable value for money" for those customers who simply want access to the internet with no other services.
"Virgin Media is the only major provider able to supply broadband without a phone line because of our unique cable network," he noted.
TechweekEurope suggested the decision to raise prices may be an attempt to encourage broadband-only customers to upgrade to a double-, triple- or quad-play bundle.
Virgin Media recently refreshed its range of broadband bundles, which offer internet, home phone and TV services, plus the option to bolt on a SIM-only mobile contract.
An entry-level broadband bundle costs little more per month than a standalone broadband deal.
Virgin Media is currently offering money off its Big Easy (£30), Big Bang (£60) and Big Kahuna (£90) bundles, which are also discounted for 12 months.
Consumers signing up for the firm's top-tier package, the Big Daddy, can get their hands on a free Samsung Galaxy Tab 4 mobile device, which ordinarily retails at £159.99.
