I don’t know what advice you’ve previously been offered, but there’s clearly something amiss in where wordpress is trying to place your files:
“Unable to create directory /home/8753/cleareality/www.cleareality.co.uk/public_html/http://www.cleareality.co.uk/wp-content/uploads. Is its parent directory writable by the server?”
/home/8753/cleareality/www.cleareality.co.uk/public_html/wp-content/uploads would be a more likely target. What do the two boxes say under your Miscellaneous settings?
