Hi Pompoms - well done on the weed battle! I garden down in Suffolk so defer to local knowledge when it comes to severity of the winter.
If your plants have been in containers for some time you should be able to plant them at anytime the soil is workable - so starting sooner rather than later to establish them before winter seems like a plan.
Just make sure you prepare the beds well with lots of organic matter as this will help to retain moisture through the summer as well as helping to support the plants in other ways. I would also suggest considering using a mycchorizal root fungus as I found this really got root systems going when I was planting a load of shrubs last year. A bigger, deeper root system should mean they're better protected against ground frosts. I would also use a thick mulch after you've given everything a really good watering - again to help conserve moisture over the summer months.
After that it's a case of keeping everything well watered (unless you're getting lots of rain) - but that shouldn't be anymore work than watering all those containers!
