I'd keep them in pots in a cold greenhouse over the winter and plant them out when they start to grow again in the spring. The foliage will die down completely soon.
You'll need to use some protection from slugs when you plant them out next year as they find delphiniums particularly tasty and will eat the new shoots as soon as they appear. If that happens to young plants like these it will usually kill them.
A trowel in the hand is worth a thousand lost under a bush.
Thanks for your help I will be watching for the slugs I am constantly at war with them!!
When my delphiniums start peeking through the soil in spring I surround them with a substantial circle of coarse sand - while it doesn't keep all the slugs off it definitely helps

Yes or you can just let them die back, your choice.
I have just bought some plugs from Thompson and Morgan and the are in the greenhouse flowering should I plant them out or leave until after the frosts
