Gas cooker. (Glenfield LE3)

Hi i'm wondering if anyone has got a gas cooker as My Mum's cooker has stopped working (it's completely broken) so My Mum badly needs a cooker asap please. My Mum is on a pension so she can't afford to buy one. I would be really grateful someone could help me get a cooker for my Mum please. (It must be Gas )
