Does radiator foil work?
It can help most on radiators fitted to poorly insulated external walls, by reflecting heat back into the room. The benefit is smaller on well-insulated walls.
Is a heated throw cheaper than central heating?
It depends on your tariff and how long you use each one. Work out your own unit rates with the meter reading calculator before deciding.
Can renters draught-proof?
Usually, yes. Removable options like under-door stoppers, brush strips and self-adhesive foam strips don't normally need permission. Check your tenancy agreement before drilling or making changes.
