Halloween Costume Safety: How to Avoid Nasty Accidents and Spot Dangerous Fancy Dress

The Chartered Trading Standards Institute (CTSI) recently reported that 91% of the children’s Halloween costumes assessed in a test-purchase investigation failed to meet legal UK requirements.

Halloween is all about dressing up, embracing the spooky season, and enjoying a few frightful festivities. But while witches, vampires and skeletons might be part of the fun, an unsafe costume can turn an evening of trick-or-treating into a real-life horror story.

The frightening truth about Halloween costume safety

Halloween costumes might look harmless hanging on a shop rail or displayed in an online listing, but appearances can be deceiving.

In October 2026, the Chartered Trading Standards Institute (CTSI) reported that 91% of the children’s Halloween costumes assessed in a test-purchase investigation failed to meet UK legal requirements. The investigation focused on costumes sold online by overseas third-party sellers and identified problems including missing safety warnings, inadequate labelling and a lack of information identifying the responsible manufacturer or importer. Although these findings should not be treated as a representative estimate of every Halloween costume on sale, they highlight serious concerns about product safety.

Fire safety is another major concern. Children’s fancy dress costumes are generally regulated as toys rather than ordinary clothing, meaning specific toy-safety requirements apply. However, even a compliant costume can burn if it comes into contact with a naked flame.

The risks are not limited to fire. Poorly fitting outfits and dark coloured clothing can all increase the likelihood of accidents.

The good news is that taking a few sensible precautions before heading out can help reduce these risks.

How to Keep Halloween Costumes Safe

Fire is one of the most serious hazards associated with Halloween fancy dress. Long, flowing sleeves, capes, wigs and synthetic fabrics can come into contact with candles, lit pumpkins, sparklers or other heat sources.
To reduce the risk of burns and clothing catching fire:
  • Use battery-operated candles or LED lights inside pumpkins instead of naked flames.
  • Keep costumes, wigs and accessories well away from candles, open fires and fireworks.
  • Avoid long, trailing capes, oversized sleeves and loose fabric that could brush against a flame.
  • Never assume a costume is fireproof simply because it carries the appropriate safety marking.
  • Consider wearing ordinary clothing underneath a costume where practical, while remembering that this does not make the outfit safe around flames.
  • Practice Safety Drills: Teach children the stop, drop, and roll method, reminding them to cover their face with their hands if clothing ever catches fire.
An outfit that is too long, too loose or too restrictive can create unnecessary hazards, particularly when children are running between houses, climbing steps or walking along pavements in the dark.
Before Halloween night, check that:
  • Trousers, skirts and capes do not trail along the ground.
  • Sleeves do not cover the hands or prevent children from using them properly.
  • Shoes fit securely and provide enough grip for walking outdoors.
  • Masks and headpieces stay in place without slipping over the eyes.
  • Fastenings are secure and do not leave sharp edges or loose components exposed.

Let children try on their complete costume before heading out. A quick check indoors can reveal problems that might otherwise cause an accident when they are outside.

Trick-or-treating often takes place in the evening, when poor lighting and dark clothing can make pedestrians difficult for drivers to see.

Adding reflective tape to costumes, choosing light-up accessories or carrying a torch can improve visibility. Glow sticks may also help, provided they are used according to their instructions and kept away from young children who might chew on them.

Adults should supervise younger children closely, particularly when crossing roads, approaching driveways or walking through unfamiliar areas.

Where possible, stick to pavements, use pedestrian crossings and avoid running between parked cars. A costume that looks fantastic in photographs is not worth compromising road safety.

What should buyers look for when buying a Halloween costume?

Choosing a costume involves more than finding the right character at the right price. A few simple checks can help shoppers identify potentially unsafe products before they are worn.

Look for the appropriate safety marking

Children’s fancy-dress costumes should carry the relevant UKCA or CE marking on their packaging where required under the applicable toy-safety rules. A marking is an important check, but it is not a guarantee that every aspect of a product is safe.

Buy from reputable retailers

Research the retailer before purchasing, particularly when shopping through an online marketplace. Check customer reviews, seller ratings and the information provided about the business supplying the item.

Read the product description and warnings

Look for clear age recommendations, safety instructions and any warnings about fire, small parts or unsuitable use. Be cautious if essential information is missing or the description appears unreliable.

Check the manufacturer or importer details

For children’s costumes, look for the required manufacturer or importer information on the packaging. This can help you establish who is responsible for the product if a safety concern arises.

Inspect the costume when it arrives

Check for loose stitching, damaged fastenings, sharp edges, poorly secured decorations, excessively long cords and other obvious defects. Do not allow a child to wear a costume that appears damaged or unsafe.

Be wary of suspiciously cheap deals

A low price does not necessarily mean a product is dangerous, but an unusually cheap costume from an unknown seller deserves closer scrutiny — especially if the listing contains little safety information.

Check for product recalls

Search the government’s product safety alerts and recalls information if you have concerns about a particular costume or brand.

If you suspect that a costume is unsafe, stop using it and contact the retailer or marketplace. You can also report concerns to Trading Standards through the relevant consumer advice service.

Halloween costume safety

While consumers can take steps to protect themselves, responsibility for safety does not rest solely with the person buying the costume.

Manufacturers, importers and other businesses involved in placing products on the UK market must consider the risks their products may pose and comply with the applicable safety requirements.

Under Great Britain's product safety framework, consumer products must be safe in normal or reasonably foreseeable use. Specific toy-safety requirements also apply to children's fancy-dress costumes. Businesses must establish compliance before products are placed on the market and respond appropriately when safety concerns emerge.

What responsibilities do Halloween costume manufacturers have?

Materials should be selected and tested with their intended use in mind. Children’s costumes are likely to be worn around pumpkins, candles and other potential ignition sources, making flammability an essential consideration.

Manufacturers should carry out appropriate testing against the relevant legal requirements and applicable standards, including the relevant toy-flammability standard. They should not assume that a fabric is safe simply because it is commonly used in clothing.

Designers should also consider how the costume behaves when exposed to heat, including whether materials melt, drip or allow flames to spread rapidly.

A costume may look impressive, but unnecessary design features can increase the risk of injury.

Manufacturers should assess whether long cords, trailing fabric, restrictive masks, sharp components or small detachable parts could pose a danger to the intended age group.

Age-appropriate design is particularly important for younger children, who may be less able to recognise hazards or remove a costume quickly if something goes wrong.

Consumers need accurate information to make informed decisions.

Packaging and product information should include the markings, warnings, instructions and identification details required by the applicable regulations. Any relevant fire warnings should be clear and easy to understand.

Manufacturers and importers should also ensure that the required business details and product or batch references are available so that products can be traced if a defect is identified.

Safety should be considered throughout the manufacturing process, not simply at the design stage.

Businesses should implement appropriate quality-control procedures, carry out relevant testing and ensure that materials and finished products meet the required specifications.

Where production is outsourced, manufacturers should still take appropriate steps to verify that the finished products meet applicable safety requirements.

A manufacturer’s responsibilities do not necessarily end once a costume reaches the shop floor.

Businesses should monitor complaints, investigate reports of defects and take appropriate action when a product presents a safety risk. Depending on the circumstances, this may include notifying Trading Standards, withdrawing products from sale or organising a recall.

Government guidance makes clear that manufacturers and importers must be prepared to address identified risks and provide information that supports product traceability.

What happens if a faulty Halloween costume causes an injury?

Even when families take reasonable precautions, accidents can happen. If an injury is caused by a defective or unsafe costume, the injured person may have grounds to explore a compensation claim.

The circumstances of the accident will be important. For example, a claim might arise where a costume catches fire because it fails to meet applicable safety requirements, or where a defective fastening, sharp component or poorly designed feature causes an injury.

Under the Consumer Protection Act 1987, a person who suffers injury or certain other losses because of a defective product may be entitled to bring a claim against a party in the supply chain, subject to the relevant legal requirements and defences. Other legal routes may also be relevant depending on the facts.

An injury alone does not automatically establish liability. It will be necessary to consider the nature of the defect, the cause of the injury, the available evidence and the applicable law.

If you or your child has been injured by a potentially faulty costume, consider taking the following steps:

  • Seek medical attention where necessary and follow the advice of healthcare professionals.
  • Keep the costume and its packaging, if safe to do so, rather than throwing them away or attempting repairs.
  • Take photographs of the costume, any visible defects and the scene of the accident.
  • Keep receipts and order confirmations, along with any product instructions or safety warnings.
  • Record what happened, including when the accident occurred and any witnesses who were present.
  • Report the safety concern to the retailer and the appropriate consumer safety authorities.
  • Seek legal advice to understand whether you may have grounds to pursue compensation.

It is important not to put yourself or anyone else at further risk to preserve evidence. Where a costume has caught fire or remains hazardous, prioritise safety and follow appropriate professional advice.

Enjoy Halloween without the horror story.

Head of Personal Injury at Watermans, Susanne McGraw, says:

"We are lucky in the UK that we have regulations that ensure clothing is safe for children and adults alike. Many think that this 'red tape' is simply another hurdle that gets in the way of companies being able to provide cheap clothing at a time where the cost of living is already high. It takes time for these regulations to go through Parliament, so there is a purpose and reason behind them, and it would be wrong for them to be disregarded. Whilst it may add a few pounds to the cost of a costume, that cost may prevent serious injury to a child so it could be said that it is well worth it. Unreputable companies are only thinking of profit and not the safety of wearer. Taking time to source a costume which adheres to UK standards could make a huge difference to the experience that a child could have on Halloween."
