Thinkbroadband reports that from July through to 24th September UK ISP's will be able to migrate ADSL broadband customers internally between providers for free.

The promotion, which is only applicable to ISP's and not end-users, will cover the IPStream, IPStream MAX (up to 8Mbps), Datastream, Datastream MAX and related premium ADSL products.

Typically it appears to cover all of the major consumer ADSL products, excluding unbundled (LLU) providers.
