do you have a fire extinguisher in your house?
if not, I highly recommend grabbing one if you can afford it. powder is a good place to start, since it works for almost all household fire types and is safe around electricals. a brand new 1kg one is about £15 and a 2kg one is about £20.
a few years back I had an incident where having a fire extinguisher in our kitchen saved me from severe burns and limited the fire damage to stuff I could cheaply repair. coincidentally, I had bought it that day.
