I'm going to hazard a bit of detective guesswork, I say hazard as I'm not going to check every page. I'm guessing that Google has mistaken "photo booth hire Surrey" as your company name in a way and I think it's due to the navigation.
View source on brighton-photo-booth-hire.html, croydon-photo-booth-hire.html and photo-booth-hire-sutton.html. When you search for the term it appears twice, both as;
<a href="https://myfunphotobooth.com">Photo Booth Hire Surrey</a> ... all the other navigation links go to their correct location, it's just the Surrey ones that link to the home page. If you times each page you have by 2 links (min) per page then site wide it's not inconceivable they think your brand name is "photo booth hire Surrey".

I don't know WordPress mate, I scratch write projects so unsure what it essential vs what can wait. I'll pm you my website so you can have a dig about and see how it's done.

I don't see how it could, it just duplicates certain rows in the posts table. Although if it's a theme, it's possible the theme editor stores the scripts etc in the database for some horrible reason. It's possible a caching plugin could be causing issues too, but it's hard to tell.
 

Great. But that still leaves 50 requests. You can get rid of a lot more  if you tweak the theme and clear out the plugins you don’t need.

My advice on general speed is to only load what's required and to split the assets accordingly. Simplified, I add essential page forming css inline in the head, and then load an external css file for everything else which requires interaction e.g. hover and focus states, lightbox gallery styles etc. You can do the same with js, for example don't load google maps on every page if it's only ever used on the contact page or don't load the gallery js unless it's on the gallery page.
