Statistics on the present education system

I have been finding it difficult to source relevant data on the present structure of education. Fortunately I have just found the latest stats from the Dept for Children, Schools and Families.

That shows some 25000 schools in England with 8.1 million pupils. For a summary table, click here.

I am now searching for basic data on the financing and budgetary side. If you know where it is best obtained please le me know. I want to research suitable sources so as to ensure that any policy ideas for the future are based on the realities of today.
