At KS Electrical Solutions, we provide professional Positive Input Ventilation (PIV) services for properties across Exeter and the surrounding areas. With over 50 years’ experience in the electrical industry, we deliver a completely bespoke service for all our clients.
PIV systems are commonly specified to help manage condensation, improve air circulation and support healthier indoor environments. Our team offers a complete service, from initial assessment through to installation, commissioning and ongoing support.
Positive Input Ventilation is a whole-property ventilation solution designed to introduce a continuous supply of fresh, filtered air into a building. Typically installed in loft spaces or designated service areas, a PIV unit gently pushes fresh air into the property, allowing stale air to be displaced through natural leakage points such as vents and air bricks.
PIV systems are commonly installed in a variety of settings and are designed to:
PIV systems are typically installed in houses, flats, offices and light commercial buildings where airflow is limited or where moisture levels need to be carefully managed.
Properties, whether homes or commercial spaces, often struggle with poor airflow, trapped moisture, and stale or stuffy air. These issues can lead to condensation, damp patches, mould growth, and even damage to walls, ceilings and furnishings.
A Positive Input Ventilation (PIV) system helps to resolve these problems by gently introducing a continuous flow of fresh, filtered air throughout the building. The results include:
Every property is different, which is why our service is fully bespoke. We carefully assess your building’s layout, ventilation needs, and moisture patterns to ensure the PIV system addresses the specific problems affecting your space. This makes it effective for a wide variety of settings, from family homes and rental properties to offices and commercial buildings.
Our electricians install PIV systems in accordance with manufacturer guidelines and current UK regulations. Each installation begins with a detailed assessment of the property to ensure the system is correctly specified and positioned for effective airflow.
We work with leading PIV manufacturers and can advise on suitable models for a wide range of property types, from older homes to modern commercial premises. Here, we break the installation process down into clear stages to keep it simple and transparent for homeowners and tenants.
Before installation:
During installation:
Once the system is in place, we explain its operation to the homeowner or tenant. We’ll also check all settings, provide you with documentation, and outline any ongoing support. Throughout the whole process, we will treat your property with care, using dust sheets and leaving everything clean before we leave.
If an existing PIV unit is outdated, inefficient or no longer functioning correctly, we can replace or upgrade the system. This includes safe removal of old equipment, installation of a new unit and full testing to confirm correct operation.
Regular maintenance keeps your PIV system running efficiently and prolongs its lifespan. Our team carries out inspections and servicing, checking electrical connections, fans, controls, and filters to ensure everything is working correctly.
Filters typically last up to five years, and we recommend an annual visual check to spot any issues early. Additionally, optional service plans are available for ongoing peace of mind, and running costs are very low — often just pennies per day. With regular upkeep, your PIV continues to improve airflow, reduce condensation, and support a healthier, more comfortable indoor environment.
Not every property is the same, but PIV can be installed in a wide range of homes and commercial spaces. Generally, a property is suitable if it has:
