Why Might You Need A PIV Unit?

A positive input ventilation system helps to control humidity in the home. It works by drawing in fresh, clean air from outside replacing stagnant, damp air inside your home. This helps to prevent issues such as damp, condensation and mould occurring, leaving you with a more pleasant and healthier living environment.

Our Locations Include

We cover most locations in the East Midlands area and would be more than happy to come to your property to see if you’d benefit from installing a PIV unit.


When we carry out a full survey of your property, we’ll advise you on whether a PIV unit would be beneficial to you and if so, where we think it should be installed to get more fresh air into your home. PIV units are often installed in a loft space or on an external wall.

The cost depends on the level of work involved and how sophisticated you want the PIV unit to be. PIV units that push around heated air will be pricier and more expensive to run. However, most PIV unit installations cost in the region of £700 – £1,000. We will provide you with a detailed quotation before carrying out any work at your property.
