The National Literacy Trust is a charity.  It has a wonderful site called 'words for life' where parents can go to access resources and information about supporting their child to become literate and enjoy reading.

'We are the UK's largest reading charity and we reach millions of children every year with books, resources and support to get every child reading, regularly and by choice.'

The CLPE (Centre for Literacy for Primary Education)

Lots of useful and interesting research and some free resources for teachers, home educators and parents and anyone interested in literacy.
