Simple steps to reduce mould risk at home (steps that are supported by UK housing and public-health)
1. Ventilate little and often
- Open windows 5–10 minutes, once or twice a day, even in winter (known as “cross-ventilation”)
- Always ventilate after:
- showering
- cooking
- drying clothes indoors
Short bursts of ventilation reduce moisture without significantly cooling the home
2. Keep a consistent indoor temperature
- Aim to keep your home at 18–21°C
- Cold surfaces + warm air = condensation
- Consistent heating helps walls stay warm and reduces moisture settling
3. Manage indoor humidity
- Ideal indoor relative humidity: 40–55%
- Regularly above 60% = high mould risk
A simple digital humidity monitor can be very helpful
4. Avoid trapping moisture
- Don’t push large furniture hard against external walls
- Leave a gap of 5–10 cm for air circulation
- Avoid heavy curtains touching cold walls
- Open trickle vents if your windows have them
5. Be careful drying clothes indoors
- Only dry washing indoors if:
- the room is well ventilated
- a window or extractor is open / on
- Never dry clothes on radiators without ventilation
Indoor laundry releases litres of moisture into the air.
6. Use extractors properly
- Use kitchen and bathroom extractor fans during and after use
- Keep doors closed so moisture doesn’t spread through the house
- If fans are noisy or ineffective, they may not be working properly
7. Deal with condensation early
- Wipe down wet windows and surfaces daily in winter
- Don’t ignore recurring condensation — it’s an early warning sign
Mould can begin to grow within 24–48 hours on persistently damp surfaces
Simple and effective measures to help you
Monitor moisture levels in your home

Monitor moisture levels in your home
Every home should have a rechargeable hand held moisture meter and humidity meter. Check known damp spots on floors and walls to quickly identify problem areas. Once damp is identified, address the cause, and deploy de-humidifiers promptly to help prevent mould growth.
Quick, easy to use and rechargeable. We have tested this damp meter model ourselves (around £25) and humidity meter (around £10):

Simple Agar plates (around £20 for 10) can be used as a basic environmental screening tool to indicate whether airborne mould may be present in the home. Windows are shut for 2 days, the plates are exposed to the air, sealed and incubated for 5 days to allow mould colonies to develop.
IMPORTANT: Agar plates are an indicative tool only and should not be used as a standalone assessment of mould exposure or health risk; they may provide useful supporting information when used alongside visual inspection and other assessment methods.

Hair is often used in toxicology testing because it can reflect cumulative exposure to substances in the environment.
So hair testing may offer useful contextual information when considering environmental factors, including mould.

But the OAT + Mycotoxin test, at a cost saving.
When there is visible mould and you're experiencing ongoing symptoms, this combined test can help build a clearer picture of how yeast and mould overgrowth, and mycotoxins may be affecting yoiur body.
Because mycotoxins have a half life, results from the Mycotoxin test may also offer useful timing context around exposure.
