Do Heated Blankets Catch Fire

Find out if heated blankets catch fire, how safe they are to use, and the best practices to reduce risk while keeping warm in the UK.

Heated blankets have become increasingly popular in the UK as a way to stay warm and cosy during colder months. They are often seen as an energy-efficient alternative to keeping the central heating running all night, providing gentle warmth at a fraction of the cost. However, many people worry about safety and ask whether heated blankets can catch fire. This is a valid concern, as any electrical appliance that generates heat carries a potential risk if it is not designed, used, or maintained correctly.

Understanding How Heated Blankets Work

A heated blanket contains thin electrical wires or heating elements that warm up when connected to mains power. Most modern blankets are fitted with thermostats and automatic shut-off features to regulate temperature and reduce the risk of overheating. They are typically made with fire-resistant fabrics that have been tested to meet UK safety standards. As with any electrical product, however, the risk of fire depends on the quality of the blanket, how it is used, and whether it has been properly maintained over time.

Are Heated Blankets Safe to Use?

The short answer is yes, heated blankets are generally safe if they are manufactured to UK standards and used correctly. Modern products sold by reputable retailers must comply with strict electrical safety regulations. They are fitted with safety mechanisms such as overheat protection, automatic timers, and low-voltage wiring to minimise hazards. Fire incidents involving heated blankets are rare, and most cases reported by fire services involve older models that have not been replaced or maintained. For this reason, experts recommend replacing blankets that are more than ten years old and avoiding the use of second-hand or uncertified products.

Situations That Can Increase Risk

Although modern heated blankets are designed with safety in mind, certain situations can make them more dangerous. Using a damaged blanket with frayed wires or scorch marks significantly increases the risk of fire. Folding or creasing the blanket while it is switched on can also damage the internal wiring, leading to hotspots. Another concern is leaving the blanket switched on for long periods without supervision, especially overnight if the product does not have a built-in timer. Pets jumping onto the bed or small children playing with the blanket can also increase risk if the wiring is compromised.

How to Use Heated Blankets Safely

The best way to minimise fire risk is to follow the manufacturer’s instructions carefully. Heated blankets should always be laid flat while in use and never folded or tucked under heavy bedding. They should be plugged directly into a mains socket rather than an extension lead, as overloading circuits can create additional hazards. Before storage, ensure the blanket is fully cool and neatly folded without sharp creases. It is also important to inspect the blanket regularly for any signs of wear, damage, or exposed wiring. If any issues are found, the blanket should be replaced immediately rather than repaired at home.

What the Fire Services Say

UK fire services advise that heated blankets are safe when used properly, but they stress the importance of annual checks and replacing old or unsafe products. Some local fire brigades even offer free blanket testing schemes for vulnerable people, particularly elderly homeowners who may have older models. Statistics show that most incidents occur with blankets over ten years old, which are more likely to lack modern safety features such as automatic cut-off mechanisms. By contrast, the risk of fire from a modern, well-maintained blanket is extremely low.

Should You Sleep with a Heated Blanket On?

Many people enjoy the comfort of sleeping with a heated blanket switched on throughout the night. While some modern blankets are designed for all-night use, it is generally safer to use them to warm the bed before sleeping and then switch them off. Automatic timers are a useful feature for those who prefer to keep them on, as they reduce the chance of overheating. Ultimately, the safest practice is to switch off and unplug the blanket before going to sleep unless it has been specifically designed for overnight use.

Alternatives to Heated Blankets

For those who are still concerned about safety, there are alternatives that provide similar warmth without relying on mains-powered heating. Hot water bottles, microwaveable heat packs, and thicker duvets can all help retain heat. Electric throws and mattress toppers are also available, many of which come with built-in safety features similar to heated blankets. Choosing the right product comes down to personal comfort, cost, and confidence in the safety of the appliance.

Conclusion

Heated blankets can catch fire if they are old, faulty, or misused, but modern designs with built-in safety features are generally safe for everyday use. By choosing a blanket that complies with UK standards, following the manufacturer’s guidance, and replacing older products when necessary, the risk of fire can be kept extremely low. With proper care, heated blankets can provide affordable warmth without posing a danger to your household.
