Electric blankets must be checked regularly and used with care. They don’t last forever and after their guarantee runs out (usually 3 years) they should be tested and serviced by the manufacturer.
It might just be cheaper and safer to buy a new one.
Portable heaters can be handy in the winter to keep the cold off but they need to be used carefully - and, extra carefully if they’re in the bedroom!
A smoke alarm placed near to bedrooms will alert you to a fire, even when you’re sleeping.
Smoking in bed is definitely not recommended, but if you do, there should be a smoke alarm inside the bedroom. Remember to test all your smoke alarms every week.
Make sure your bedroom door is kept shut at night – it’ll will help stop the spread of smoke and flames if fire does start.
