With temperatures soaring across the UK, many homeowners are looking for ways to keep their homes cool, comfortable and healthy. If you're struggling with overheating rooms, sleepless nights, condensation, or poor indoor air quality, the answer may lie in your home's ventilation strategy.
Modern homes are built to be more airtight and energy efficient than ever before. While this helps reduce heat loss and lower energy bills, it also means that fresh air cannot enter the home as easily. Without effective ventilation, homes can become stuffy, humid and uncomfortable, particularly during periods of hot weather.
To help homeowners, self-builders and renovators better understand their options, the National Self Build & Renovation Centre (NSBRC) is hosting a FREE Ventilation Drop-In Clinic on Saturday 4th July.

Why Ventilation Matters
Good home ventilation does far more than simply move air around your property.
A well-designed ventilation system helps remove stale air, excess moisture, pollutants and allergens while introducing fresh, filtered air into the home. The result is a healthier indoor environment and improved year-round comfort.
Effective ventilation can help:
- Reduce overheating during hot weather
- Improve indoor air quality
- Filter pollen and airborne pollutants
- Help relieve hay fever symptoms
- Prevent condensation, damp and mould
- Improve energy efficiency
- Meet current building regulations
- Create a healthier living environment
Whether you're planning a self-build project, renovating an older property or upgrading your existing home, understanding ventilation is an important part of creating a comfortable and energy-efficient home.

Learn About MVHR and Modern Ventilation Systems
One of the most popular solutions for modern homes is Mechanical Ventilation with Heat Recovery (MVHR).
MVHR systems continuously extract stale air from wet rooms such as kitchens and bathrooms while supplying fresh, filtered air to living spaces and bedrooms. The system recovers heat from the outgoing air and uses it to warm incoming fresh air, helping to maintain comfort and energy efficiency.
At the Ventilation Drop-In Clinic, visitors can learn how MVHR works, explore alternative ventilation solutions and discover which systems may be most suitable for their project.
