A few herb tips off the top of my head.
Basil - doesn’t like root competition - buy a pre-planted pot but separate each plant before planting out. You can do this more easily under water in a bucket! The plant, that is. The difference is worth it. Buy Greek (small-leaved) basil for a change - it grows well and to a bigger size. Basil doesn’t like cold so don’t plant out just yet.
Rosemary is a shrub. It varies between woody giant, tiny rockery, and prostrate tumbling varieties. Most taste the same, but there’s a lot of difference in the hardiness. There’s a fairly compact one that flowers through winter (looks pretty) which was bred in Canada and is v. hardy called “Bonny Jean”.
Thyme - Reliable, low-growing subshrub (i.e. it’s supposed to get woody!) Lots of different flavoured varieties. Needs sun.
Oregano (aka Wild Marjoram) is a British native, as is thyme. Expect it to attempt to take over your garden (in a good way this time) if you are on chalk.
Try wild garlic (Allium ursinum) on shady banks. True garlic needs a sunny veg. patch.
Mint - don’t forget there are different species (different flavours) of mint too.
Don’t forget sage - another shrub! There are decorative variegated and purple leaved varieties so you can use them decoratively too.
