Hoarding: 'Thousands of homes could be at risk of fire'
About 670 hoarders are known to Welsh fire services but they estimate up to 150,000 people could have the disorder.
Statistics show 25% to 30% of fire deaths are related to hoarding.
A leading fire officer in Wales has said extra resources are needed to protect those at risk of death or injury in house fires across Wales.
The Welsh Government said it had invested £3m in psychological therapies in Wales in the past two years.
