It's the Lack of choice for schools From ICT4Leeds / Leeds Learning Network.
Even offering a 2 year deal at a more expensive price may have tempted more schools into moving to ICT4Leeds.
But schools can sign up for a 1 year contract with another provider, if they don't like it the can move on the following year. But if they don't like ICT4Leeds, they're tied in for 4 years.
Sorry, just my opinion. Hope schools make the right choice
