Hoarding Level IV: Serious
Level IV is serious. Several rooms are unusable, exits are blocked, and there may be pests, mould, spoiled food, animal waste or structural damage. The health and safety of the people living in the home are at risk, and specialist trades are usually needed before hands-on sorting can start.
Signs of a Level IV home
- Access
- Exits blocked, and parts of the home can’t be reached.
- Rooms
- Several rooms unusable, including essential ones like the bedroom or bathroom.
- Hygiene
- Strong odour, spoiled food, mould, or animal or human waste.
- Pests
- Established insects or rodents.
- Structure
- Water damage, leaks, broken fixtures or sagging floors.
- Utilities
- Some appliances or services not working.
Risks at this level
- Serious fire risk and difficulty escaping
- Health risks from mould, pests and waste
- Falls and injuries, and difficulty for paramedics to reach someone
- Tenancy, insurance or council action
First steps
- Check whether anyone is in immediate danger. If so, call 000
- Arrange pest control and, where needed, specialist biohazard cleaning
- Fix urgent repairs, such as leaks, power or gas
- Clear safe exit paths
- Start emotional and planning support alongside the trades
If it’s a family member’s home
Safety comes first, and forced clear-outs often lead to distress and relapse. Involve the person’s GP where you can, and keep the person in the decisions about their belongings even while trades make the home safe.
How to help a parent who hoards →Common questions about Level IV
Do you work on site at Level IV?
Not straight away. Pest control, biohazard cleaning and repairs are separate trades and come first. We support the person and family by video while that happens, then hands-on sorting can start once the home is safe.
Who should be involved at Level IV?
Usually the person, their family, a GP, and trades such as pest control and specialist cleaners. If a landlord or council is involved, a coordinated plan helps everyone.
