Right so I built a homegym and in UK. By far the best options are either Strengthshop or BulldogGear.
I went with bulldog gear in the end and would recommend. It's literally a rogue clone but for UK, by far the best I've seen, quality better than strengthshop and also the cheapest for what I needed. (Squat stand, dip wall thing, plates, non power bar, spotter arms, bench etc)
Another nice thing is that they are growing bigger and offering more items identical to rogue but cheaper price in UK.
I spent months autistically looking so I'm sure these are the best options. (Although, a full cage is probably cheaper from strengthshop)
I'm not sure if strengthshop save much from a quote, but if you need a lot of homegym items, it's worth contacting both companies. I saved a lot of money with bulldoggear because I just contacted them about offering a discounted price since I was ready to get almost everything from them.
