Amazon Event Shelter Gazebo - £91.68 @ Amazon

Looks like an identical design to the older Coleman Event Shelters - I wonder if they've licenced/sold the design to Amazon as they move to on to their newer designs.

The straps on the floor in the main pic aren't needed once you've put the feet in place, it's just a reference to make sure it's put up square.

Total blatant theft of design from Coleman

I've had a couple of the Coleman shelters which this looks very similar to. I first had the XL Pro which I bought 2nd hand It was brilliant quality just a little large and heavy to fit in my car for camping trips.

II then bought the small version which was noticeably poorer quality fabric, so poor I returned. I suspect this may be made under license by the same people but with the steel poles they're still bulky and heavy. The one on Amazon is between the small and the XL.

I saw Asda have a Ozark Camping Sun Shelter for £89. Erected it's a similar size as the Coleman XL @ 4.3m square but it uses fiberglass poles meaning it's lighter and a smaller package. It may be flimsier to as a result. If you need one to take with you this may be a better option than the one in the OP however if you're just going to use at home the ones with the steel poles may be a better bet. I think in either case the fly sheet will fail before the frame.
