I think you may have som good plants there, so don't rush to cut them back. Wait and see how they perform. Evergreen shrubs (which some of them must be) are usually quite low-maintenance and give interest all year round.
Looking at your photo, it looks as if you've got a whopping great honeysuckle on the left-hand fence. You may want to prune that drastically, they can rather take over (and they can block drains). On the bottom right, it looks like lily of the valley, which either won't grow or won't stop growing (the latter in your case! Mine all died). You might want to get that under control too. Close to the path you have some pretty dianthus (pinks) and some sort of herbaceaous thing (a geranium?) that may soon flower. Those look worth keeping. At the back there'a nice yellow bush - possibly euonymus, which is attractive all year round. Between the solar lights is possibly a herb (oregano?), I'm not sure, and behind it is what looks like a hydrangea - leave that alone and see if it flowers later in the summer. They're usually quite well behaved. The heather looks a bit big and dominant, but they're not eay things to tame once they spread.
All this is just opinions and guesses, but do give your garden time to show you what it can do, and then you can decide what you want to keep or change. You'll get lots of support here.
