An Affordable Solution for Condensation, Mould & Stale Air
Condensation on your windows. Black mould is creeping into corners. Stale, stuffy air that just won’t shift. If any of this sounds familiar, a PIV system could be the answer.
From just £899 all in, The PIV Company provides professionally installed, low-maintenance ventilation that tackles the problem at its source – not just the symptoms. Every installation includes a full property assessment, expert fitting by NAPIT-accredited engineers, and an EIC certificate, with no surprise charges.
With over 10 years of experience in damp and ventilation, we know what works. Take our quick suitability checker to find out if a PIV system is right for your home, or call us today.
A Modern Solution for Condensation, Mould & Stale Air
No two homes are the same, which is why we offer a range of Positive Input Ventilation systems to suit different property types, layouts, and air quality concerns. Here’s an overview of what The PIV Company can install for you:
Loft-Mounted PIV Units – Ideal for Houses with a Loft or Attic
Loft-mounted PIV units are our most popular solution, and for good reason. Discreet yet highly effective, they’re ideal for houses with an accessible loft space. The system draws in fresh, filtered air from the loft and distributes it evenly throughout your home, quietly working in the background to improve air quality without disrupting your day-to-day life.
Wall-Mounted PIV Units – Solutions for Flats and Bungalows
Wall-mounted PIV units are designed for properties without loft access, making them the ideal choice for flats, apartments, and bungalows. Compact and versatile, each unit is installed directly onto an internal wall, delivering the same fresh, filtered air and condensation control as our loft-mounted systems, just in a form that works for your property.
Bespoke to Your Property
No two homes are the same, so we never guess. Our ventilation assessors visit your property in person and recommend the right PIV unit based on a selection of factors:
- Whether your property has an accessible attic/loft space
- The presence and severity of condensation or mould
- Existing airflow and ventilation levels
- The type, size and layout of your property
From there, we’ll recommend and install a system that suits your home and your budget:
- Whole-House PIV System – Complete Protection, Every Room
- Flat & Apartment PIV System – Compact, Effective Protection
- Loft PIV System – For Houses with Loft Access

Frequently Asked Questions
Looking for information about our PIV products and services? We’ve compiled answers to our most frequently asked questions below. If you need further assistance, don’t hesitate to contact us
How does a PIV system work, and why does it matter?
A PIV (Positive Input Ventilation) system is a simple but effective way to keep your home smelling fresh and feeling healthy. It works by continuously introducing clean, filtered air, gently pushing out the stale, damp air that causes condensation and mould, without you ever having to think about it.
Will a PIV system work for my property?
Most homes are suitable for a PIV system, including houses, flats, and bungalows. Our assessors carry out a full review of your property before installation to make sure it’s the right solution. If it’s not, we simply won’t install.
How long does it take to install a PIV system?
Most installations take just a few hours. Our engineers work efficiently and cleanly, with minimal disruption to your home or business.
What warranties and certificates will I receive?
Every installation comes with an Electrical Installation Certificate (EIC), a manufacturer’s warranty on your PIV unit, and the peace of mind that all work is fully insured. Our installers are NAPIT registered, so you know you’re in safe hands.
Can a PIV system really solve damp and condensation issues?
Yes, and not just on the surface. PIV systems target the root causes of black mould, damp walls, and window condensation by improving airflow and removing the excess moisture that causes them in the first place.
Are the system settings protected from tenant interference?
Every unit comes with tamper-proof controls fitted as standard. Set it, leave it, and let it work, perfect for landlord-managed properties.
