I recently moved my Drupal 7 site to a new hosting server and I\'m stuck at the login page. As soon as I try and log in, I get directed back to the same page, but the URL change
I suspect your $cookie_domain in /sites/default/settings.php is incorrect.
$cookie_domain
/sites/default/settings.php
Try making it match your new domain and ensure there's a leading dot .

$cookie_domain = '.mydomain.co.uk';
