Positive Input Ventilation (PIV) Systems in Lancashire
What is Positive Input Ventilation ?
Positive Input Ventilation (PIV) is a whole-home ventilation system designed to reduce condensation by improving the airflow inside your property. It works by drawing in fresh air, filtering it, and gently introducing it into the home. This creates a steady flow of air that helps push out the stale, moisture-heavy air that causes condensation to build up.
For homeowners and landlords, the main benefit of PIV is that it tackles the cause of the problem rather than just the signs of it. Instead of repeatedly cleaning mould or wiping down wet windows, a properly installed PIV system helps lower moisture levels throughout the property, making it harder for condensation, damp and mould to return. It can also help create a fresher, healthier indoor environment with better overall air quality.

Our Process
Is a PIV System Right for Your Property?
A PIV system is ideal for properties where condensation is caused by poor airflow and trapped moisture. It’s particularly effective in homes where humidity builds up over time and has no consistent way to escape.
PIV may be the right solution for your property if you’re experiencing:
- Condensation on windows, especially in the mornings
- Mould growth on walls, ceilings, or around windows
- Damp patches that keep returning
- A property that feels humid or poorly ventilated
- Issues in multiple rooms rather than just one area
PIV systems work best as a whole-home solution, helping to balance airflow throughout the property and reduce moisture levels consistently.
If you’re unsure whether a PIV system is right for your home, we can assess your property and recommend the most effective solution.
