Don’t Just Insulate, Ventilate! VENTI Group Ltd Launches New Campaign to Tackle UK’s Growing Damp and Mould Crisis

A growing number of UK homes are grappling with severe damp and mould issues, a direct consequence of poorly executed government-subsidized insulation retrofits. This crisis has highlighted a critical disconnect between a focus on energy efficiency and the fundamental need for proper ventilation, prompting a renewed discussion on risk management and sustainable development within the domestic building sector. VENTI Group Ltd, a leading supplier of residential ventilation systems, is addressing this systemic failure head-on by championing the “Insulate Tight, Ventilate Right” principle.

In response to the crisis, VENTI is leveraging its expertise and product portfolio to provide a holistic solution for affected homeowners. The company reports an increase in inquiries from homeowners struggling with condensation and mould after upgrading their properties’ thermal fabric without an accompanying ventilation strategy. This problem is rooted in a lack of competent installers in the industry, who often fail to recognize that making a home more airtight necessitates a new way to manage indoor air quality.

VENTI’s core solutions, including decentralized Mechanical Heat Recovery Ventilation (dMHRV) systems like the FLUXO and AUREN, are specifically designed to address these challenges. Unlike simple trickle vents, these systems provide a controlled exchange of stale, moist indoor air with fresh, filtered outdoor air via a highly efficient heat exchanger. This process removes airborne pollutants and excess humidity, preventing the conditions that lead to condensation and mould, all while minimizing heat loss. The decentralized design makes these units ideal for retrofit, refurbishment, and extension projects, offering a straightforward yet powerful solution where traditional ventilation methods are no longer effective.

“The current crisis is a stark reminder that we cannot treat building retrofits in isolation,” said Bradley Pallister, Technical Manager at VENTI. “By making homes airtight without considering how to manage the moisture and pollutants, we are creating a new set of health and structural problems. Our FLUXO and AUREN systems are designed precisely for this challenge, providing a controlled, continuous flow of fresh air that works in harmony with modern insulation to protect both the building fabric and the well-being of its occupants.”
