Lixxus, a new ISP to many, has launched a broadband service this week that only charges users for the bandwidth they use, and no monthly subscription. The company charges by the amount of data downloaded, a tariff structure that should benefit light or irregular users who only download 1GB of data or less a month.

Users are charged 5p  per megabyte for the first 300MB and the above this £15 point, they are charged 0.225p  for each additional megabyte, up to a maximum bill of £25 per month. These prices don't include VAT so the maximum charge would be £29.00 per month.
While this isn't cheap by today's standards, very light users would be the ones to benefit.
For instance someone downloading 1GB a month would be billed £17.62 for the first 300MB and £1.85 for the next 700MB, equal to around £19.50 a month.
Lixxus recognise that this will fit into a niche within the broadband market.

PlusNet and Eclipse have announced products which take advantage of BT's itemised billing, but Lixxus have beaten them out of the trap.
