Condensation and black mould don’t happen by magic. They’re a sign your home is holding on to moisture and stale air. A PIV unit fixes that by pushing a gentle flow of filtered, fresh air from your loft into the house. That slight positive pressure moves the old, damp air out through trickle vents and gaps, so your rooms stay drier and fresher.

Why choose PIV

• Cuts condensation and mould by reducing indoor humidity
• Cleaner air thanks to built-in filtration that helps trap dust and allergens
• Warmer feel as dry air is easier to heat, helping reduce window misting and musty smells
• Quiet and low running cost typically only a few pence per day
• Set and forget continuous operation with simple filter checks
• Heated option available to gently temper incoming air on colder days

How we fit it

• Loft-mounted unit with a neat ceiling diffuser, usually in the landing
• Discreet install, no mess, typically completed in a single visit
• Plug-in or hard-wired via a fused spur by a qualified electrician
• We show you how to use it and advise on trickle vents for best results
