Don't even think of buying *drawn* frames.
Insulate.
If the bees are in a full hive, use a dummy board to bookend the frames they are using plus (at most) two of foundation. Those frames to be tight to one side/end of the hive.
The ideal place for the undrawn frames (one at each side of the brood nest) is between the last frame with brood and any that are stores-only (if the outside frame has brood, then outside it). Add another frame once one is drawn.
Fill the void space beyond the dummy with, for example, a binbag of polystyrene chippings.
Close any hole in the cover/crown board not being used by your feeder. The feeder would normally be surrounded by a shallow (super) box.
Use a feeder that you can refill without removing. Keep it topped up.
And insulate around it - and if possible over it as well.
Feed 50/50 syrup for now. 50/50 by weight, white sugar and water.
Ideal fuel for comb-drawing, which is your current priority.
Reduce the entrance to about three fingers-worth - principally to prevent robbing by wasps.
Later you can change to stronger 60/40 syrup (for storing), but after October they are unlikely to take any syrup, so additional support would then be in the form of fondant (which Americans call 'candy').
Have you asked one of your pals from your Association to come round and take a look at your bees?
