A common question we receive is: Should the toilet extract fan be interlocked with the lights?

Integrating the extract fan control with lighting is often a practical solution, as it ensures the fan operates whenever the bathroom is in use, thereby enhancing ventilation. However, this approach isn’t always ideal. For instance, in bathrooms with ample natural daylight, the lights may remain off, leaving the fan inactive when ventilation is still required.

The optimal solution depends on the specific characteristics of the space and user preferences, striking a balance between functionality, comfort, and sustainability.

Additionally, if using a manual bathroom extract switch, be sure to include a timer. This ensures the fan runs long enough to effectively remove moisture, reducing the risk of mould growth.
