Too much moisture increases the risk of mould and means you need more heating to keep surfaces dry.
By reducing excess moisture, your heating works more effectively and goes further, without turning the thermostat up.
If you have a relative humidity monitor, use this tool to check your moisture levels.
What next?
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.
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.
