Are you paying more to heat wet air?

Moisture too low 🏜️

Air conditioning or over-use of a dehumidifier can cause the air to be too dry. Check the settings, or rethink the use of these interventions.

You can also add moisture to your air carefully — some people put a small bowl of water on the radiator, for example.

Dry to normal ✅

Your moisture levels are on the lower end of the healthy range. Keep an eye on things, especially in winter when heating can dry the air further.

Just right ✅

You are maintaining a healthy moisture level in your home. Carry on doing what you are doing.

Normal to wet ⚠️

Your moisture levels are creeping up. Act now to avoid mould risk and higher heating costs.

Step 1 — Reduce moisture and ventilate more: Open windows regularly and make sure extraction fans are on and working.

If moisture remains high despite ventilating, there may be a hidden water source in your home. See the advice below.

Moisture too high 💧

Act fast to avoid mould and other biotoxins that are hazardous to health.

Step 1 — Reduce the amount of moisture you generate and ventilate more:

• Open windows regularly and make sure extraction fans are on and working
• Keep wet room doors closed to avoid moisture spreading to dry areas
• Avoid drying laundry, towels or hair in dry rooms

Step 2 — Finding a moisture source in your home:

If moisture remains high despite ventilating, there may be a hidden water source in your home. An independent damp or housing pathology surveyor* will help you to identify issues in your property.

*Avoid free surveys — these companies normally have a product or solution to sell, which may not be the remedy your home needs.

Step 3 — Want to find the issue yourself? A thermal imaging camera is a great way to check for water leaks inside walls and under floors.
