Logged in Users

Hi, so…

I’m working on a site – https://www.the1810company.co.uk
and I have an area of the site called the ‘trade portal’
which I have a specific menu set up for.

This menu only appears if users are logged in as ‘wholesale customers’
which is great and exactly how it should work.

Issue I have is that all pages within this section are supposed to only be viewable by logged in users, but if you were to stumble on one of these pages in a google search then non users can see these pages.

For instance this page – https://www.the1810company.co.uk/credit-application/
is for wholesale customers to use to apply for a trade account. But currently non logged in users can see the page also.

What should happen here with non logged in users?
Should they be redirected to the login page or a 404?

Im stuck, send help!
