Composting worms will not survive in temperatures below 4 degrees Celsius. In some parts of the UK, the temperature will dip lower so now is the time to consider keeping them warm. It's worth noting that worms will continue activity in the bin but will slow down with temperatures below 10 degrees Celsius.
1: Storing your worm bin:
Shed
Garage
Outbuilding
Sheltered corner of the garden
2: Keep your worm bin off cold floor:
The Ferme du Moutta has wheels so is off the floor. If your worm bin doesn't, then consider standing it on polystyrene, bricks or wooden blocks.
3: Storing a worm bin outside.
My bin was outside last Winter, even when the temperatures reached 4 degrees Celsius. Worms will burrow and move to the central interior or middle trays. My worms inside the Ferme du Moutta survived but the odd escapee froze and I found them on the cold ground next morning.
If outside, consider wrapping the exterior with old carpet or bubble wrap but DO NOT block ventilation holes. Some layer the interior with an old jumper - try your local charity shop. Stuff with cardboard and / or straw.
