Rick, Firstly thankyou for your time on this it is massively appreciated and i would buy you a pint if you worked for me :)

Please find below the schema for the other 2 tables i am joining too. I do have these indexed. I also amended my query and removed the left from the joins to group and data however i do need the left join on the site rates as they may be nulls.
