Problem is in this rule:

#Force from http to https
RewriteCond %{SERVER_PORT} 80 
RewriteCond %{HTTP_HOST} !^bbb.example.co.uk/$
RewriteRule ^(.*)$ https://bbb.example.co.uk/$1 [R=301]

Change this rule to:

#Force from http to https
RewriteCond %{HTTPS} off 
RewriteCond %{HTTP_HOST} =bbb.example.co.uk
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301]

You have condition reversed due to use of ! at start and have an extra slash at end which will never be matched hence making your condition always return true.

Make sure to clear your browser cache before testing this.
