I have been overwintering chillies in a frost-free greenhouse for several years with some success (and some failures!). However, when they survive it does give you an early crop, much earlier than any seed-raised plants. If they drop their leaves don't worry. So long as the stems stay green they will re-shoot. You can cut them back, too, but leave about 20cm/8" of framework and keep the soil barely damp.
