Not too much known on ADSL4LESS claims to be the cheapest Broadband in the UK which to me is not a good sign. They are probably a VISP but a VISP of whom ? 512Kbs for £14.99 inc VAT does not to me seem sensible.
The company has been Trading for 3 months and is based in Jersey and claims to have 3000 customers. Thats a sign up rate of 1000 a month to me this seem an unlikely rate to achieve.
My view is this is very definatly one for the risk takers
