A trial of BT's high speed fibre broadband has been described by experts as "the lowest fibre service in Europe".

The fibre broadband trial will take place in Kent, but will start by offering just 2.5Mbps. Five different speeds options will be available in total to the 300 newly built homes in Ebbsfleet, Kent, ranging from 2.5 to 10Mbps. Upload speeds will range from 0.5 to 2Mbps. Some options will, however, also feature 'bursts' of faster download speeds.

Jupiter Research analyst Ian Fogg told the BBC: "I am surprised. This is a trial and I see no reason why they aren't trialling the highest speed the technology can deliver. What is the point of a trial if you don't really test things?" he said.

A BT spokesperson said the speeds would be "higher in fact that anyone currently needs".

BT is hoping to encourage Ebbsfleet residents to take part by offering reduced telephone line rental although this must first be approved by Ofcom.

Andrew Ferguson, editor of broadband comparison site ThinkBroadband, said: "How often people at Ebbsfleet will see 100Mbps speeds depends on how much capacity is available to link the site to broadband providers, and how much capacity they have out to the internet."
