I'm not sure what you mean, Des. Are they very young plants or did they grow poorly and not form tubers? I am not sure if they will survive winter but your best bet is a frost free greenhouse, cool and bright and very little watering, I should think. If they are not very special, it might not be worth the trouble because well formed tubers will be available and inexpensive in Spring.
My Dahlia tubers are washed and dried anytime now , removing all traces of soil ; stored in the dark , bone-dry in a cool spare room upstairs . I do this every year and they always seem to 'get through' .
I have grown some of my Dahlias from seed for the first time. I was told that they would form tubers this year, so should I lift them just as I do with established tubers or leave them in their large pots and put them somewhere sheltered over the winter?
I grow Bishops Children from seed, it’s amaing how big the tubers are now, I have brought the ones I grew in big tubs, into the greenhouse while the soil drys off on them then, when they are dry, i will wrap them in newspaper and store till next year, the ones in the garden stay out with a big pile of home made compost on the top.
I wonder if the OP has those tiny ones they sell in supermarkets, if they were full sized dahlias they would have made tubers. If so, I would dump them and start again next year.

Gardening on the wild, windy west side of Dartmoor.
Thanks Posy and Lyn. I will put the seeded (tubers) either in or just outside the cold greenhouse, with a covering and hope for the best. I am very pleased with my seeded Dahlias, they took a while to get going but have flowered continually over the summer and now into the autumn.

With your mild winters they should be fine in a sheltered position, though they probably have made tubers if you prefer to lift them.
