Hmm, ok. So you'll be handling the .com which targets the UK and each other location will be responsible for their own optimisation?
That does make it somewhat more viable, provided they are actually going to optimise their respective sites and do it properly.
If not, there's still no real reason why all locations couldn't exist in subfolders for all the reasons I mentioned above.
As a working example of a large site covering multiple locations with this subfolder model, check out HP. Below are 2 different location "home pages" depending on where you are.
http://www8.hp.com/au/en/home.html
http://www8.hp.com/uk/en/home.html
Depending on your position in the company/team, if I were in your shoes I'd be pushing to have all locations run from the subfolder model and setting the international standard that other locations must abide by to keep it all uniform. ie Each page must use the same template including styling etc and cover the same information on their equivalent pages.
As an example, since artificial grass is your product, you might add content to your UK page that offers sections about general information, size and colour options, photos of the product and shipping information for the UK in that order.
You can then use that as a template that must be followed for /dk/, /uae/ etc. The aim here isn't to be a control freak but to maintain a certain standard of quality and continuity; the last thing you want is for any use who jumps from one location to another to feel as though they just arrived on a new website. Much like in the HP example, it's actually pretty hard to tell you're on a different subfolder until it comes to shipping or price information.
Also, I hope you don't mind but I had a 30 second skim over your website. While it's generally a pretty good site, it is a little too keyword-heavy and this isn't something you want to replicate across multiple subfolders.
Looking at the page title for the home page as an example, it's Artificial Grass Lawn, Astroturf, Fake Turf | Easigrass.
The fact that it starts with "Artificial Grass Lawn" is already a signal to users who see your site in the SERPs that it's probably quite spammy and should be avoided.
There are a few other similar elements on the site too, even the location page URLs:
http://www.easigrass.com/uk/glasgow-artificial-grass/
Just easigrass.com/uk/glasgow would be sufficient. Having 25+ pages with artificial-grass in the URL isn't ideal.
I also found 5x 404s and a bunch of internal links pointing to redirected pages. If you want to look into these, Screaming Frog's SEO Spider is a great option for that.
Also, from a user perspective I'm a little confused as to why there are locations under "Find Local Branch" and what seems to be a different set of locations under "Artificial Grass".
Rand actually just did a Whiteboard Friday that covers some of this if you'd like some more info
