Electric blankets cause more than 5,000 fires a year, 99% of which are believed to be caused by blankets over 10 years old.
If your blanket (or its flex) shows any of these danger signs, you should have it checked or replaced:
You should replace you electric blanket at least every 10 years. Don't buy a second-hand blanket. Look for the British or European standard and make sure it has a safety certification mark. Make sure the blanket has an overheat protection.
Make sure your blanket is tested by an expert at least every three years. You can ask the shop where you bought it about testing and servicing, or contact the us.
