That really depends on what type of control you have on editing the pages. Is it only in theme settings or a page builder or directly in the php files. How did you add the logo?
Also, I should note that what you really should move is the surrounding
<a> element container and not just the image. Otherwise, you won’t be able to click the logo to get to the home page.
<a href="https://www.sassco.co.uk" aria-current="page" class="menu-image-title-hide menu-image-not-hovered">
<img width="194" height="50" src="https://www.sassco.co.uk/wp-content/uploads/2019/07/main-banner.png" class="menu-image menu-image-title-hide" alt="">
I don’t think I can really help you with this as I don’t know what control and options you have for editing the page.
