How to Separate Laundry in Care Homes: Colour Coding and Risk Categories Explained

Proper laundry handling in care homes is more than just good housekeeping—it’s a core part of infection control, resident dignity, and regulatory compliance. When laundry is mishandled, cross-contamination can quickly become a serious risk for both residents and staff.

In this article, we explain how to separate laundry in care homes correctly using colour-coded systems, risk categories, and best practices commonly recommended across healthcare and care environments.

If you’re unsure whether your current laundry separation process follows best practice, we can review your setup and recommend safer, compliant solutions for your care home.


Why Laundry Separation Matters in Care Homes

Care homes process large volumes of laundry every day, including bedding, towels, personal clothing, staff uniforms and occasionally heavily soiled items. If these items are washed together without proper separation, pathogens can spread between loads.

CQC inspections and infection-control audits frequently review laundry procedures. Establishing a safe and consistent separation process helps demonstrate compliance and ensures staff follow clear routines.


Step 1: Use Colour-Coded Bags for Sorting

Colour-coded laundry bags are one of the simplest and most effective ways to separate laundry by risk category before washing.

Typical systems used across healthcare and care homes include:

Colour Use
Red (water-soluble) Infectious or heavily soiled laundry
White / Clear Personal resident clothing
Blue Soiled but non-infectious items such as bedding or towels
Green Kitchen laundry such as aprons or tea towels

Best practice recommends placing red water-soluble bags inside white outer bags and transferring them directly into the washing machine without opening them. This reduces airborne contamination risks and protects staff handling laundry.

If your care home isn’t currently using a structured colour-coded system, our team can advise on the right bags, containers and equipment.


Step 2: Keep Laundry Bins Clearly Labelled and Covered

Each laundry collection point should:

  • Use colour-coded signage matching the bags
  • Provide lidded, easy-clean containers
  • Keep dirty laundry separate from clean storage areas

This clarity helps staff follow procedures consistently, particularly agency staff or new employees.


Step 3: Train Staff to Identify Risk Categories

Items should be sorted according to risk category, not just appearance.

  • Infectious laundry includes items contaminated with blood or bodily fluids
  • Heavily soiled items may still require higher-temperature wash cycles
  • Personal clothing should usually be washed separately to reduce cross-contamination

Wall charts or visual guides in the laundry room can help reinforce the correct sorting procedures.

If you’re unsure whether staff are following consistent sorting practices, we can review your laundry workflow and recommend improvements.


Step 4: Pre-Treat and Handle Soiled Laundry Safely

Handling procedures before washing also play a key role in infection control.

  • Remove solid waste before bagging
  • Avoid shaking contaminated bedding
  • Place infectious items directly into water-soluble bags

These precautions reduce contamination risks and protect staff handling laundry.


Step 5: Use Correct Dosing and Disinfection

Once separated correctly, laundry must be washed using the correct chemical dosing and temperatures. Many care homes now use auto-dosing systems to maintain consistent disinfection levels and reduce human error.

If your home is reviewing its current setup, explore our laundry chemicals and auto-dosing systems.


Step 6: Use the Right Machines for Each Load Type

Commercial washing machines used in care homes must meet infection-control requirements.

  • Machines should support thermal disinfection cycles
  • Wash programs should reach 65–71°C
  • Equipment should be cleaned and maintained regularly

Final Thoughts

Knowing how to separate laundry in care homes is a crucial part of infection prevention. With the right colour-coded systems, clear staff training and suitable equipment, care homes can minimise contamination risks and maintain regulatory compliance.

FAQs: Laundry Separation and Colour Coding in Care Homes

Most care homes use the NHS-aligned system:

  • Red (water-soluble): Infectious or soiled laundry (blood, faecal matter, bodily fluids)

  • White or Clear: Resident personal clothing

  • Blue: Non-infectious soiled laundry (towels, bedding)

  • Green: Kitchen laundry such as aprons and tea towels

Infectious laundry should go straight into red water-soluble bags, placed inside white outer bags, and transferred directly to the washing machine unopened. This minimises staff exposure and airborne contamination.

Laundry is usually divided into three risk levels:

  • High-risk: Infectious or isolation laundry

  • Medium-risk: Heavily soiled but non-infectious items

  • Low-risk: Personal or lightly soiled laundry
    Understanding these helps staff choose correct washing temperatures and disinfection cycles.

Use clear signage, wall charts, and colour-coded bins to match bag colours. Regular staff training and refreshers help everyone follow the same infection-control process.

Yes. CQC and local authorities often review how laundry is separated, stored, and labelled during audits. Following a clear colour-coded system supports compliance and shows best practice.

Thermal disinfection requires at least 71°C for three minutes or 65°C for ten minutes. If lower temperatures are used, detergents must meet EN 1276 or EN 1650 standards for chemical disinfection.
