Virgin Media says it will offer faster download speeds when there is sufficient customer demand.
The broadband provider currently offers up to 120Mb download speeds in the UK via its fibre network.
However, the company trialled 1.5Gb broadband services in 2011 - speeds far in advance of those currently available to UK households.
Speaking to ISPreview.co.uk, a spokesperson for Virgin Media said the company is continuing to pilot new technologies to boost end-user download capabilities.
"We continue to test various speeds to be ready for when we think the time is right to pre-empt consumer demand and maintain our lead as the UK's fastest widely available broadband company," they told the news provider.
Back in 2008, Virgin Media set itself a target of offering 200Mb broadband speeds by 2012.
However, the firm's spokesperson said these speeds have been "superseded" by the firm's 1.5Mb trials.
