UPDATE:
<ifmodule mod_rewrite.c="">
RewriteCond %{SERVER_PORT} !^443
RewriteRule ^ https://www.domain.co.uk%{REQUEST_URI} [R=301,L]
</ifmodule>
- so mostly sorted - But do I need to do anything form an SEO perspective?

All your pages will be indexed without the https, but with that 301 redirect it will tell Google that this has now moved Permanently and it'll then index the https version. So it just a case of waiting for google to re index.
