A home with good ventilation contributes to better health and a safer home. Read our guide for valuable tips on improving your home's airflow, preventing condensation, and keeping your heating costs manageable.
Without adequate airflow, issues like damp and mould can arise, impacting your health and your home’s structure.
Why is Home Ventilation Important?
Ventilating your home means replacing stale indoor air with fresh air, which offers numerous benefits:
Reduces indoor pollutants, allergens, and airborne viruses, especially important for anyone with asthma, respiratory issues, or allergies.
Eliminates unpleasant odours, including lingering cooking smells and bathroom scents.
Prevents condensation, damp, and mould, protecting your property from potential damage.
The Importance of Effective Ventilation
Imagine entering a room that feels stuffy and smells musty. It is uncomfortable and could signal poor ventilation. Proper ventilation removes excess moisture, pollutants, and odours while allowing fresh air to circulate.
“Indoor air pollution 3.5 times worse than outdoor air pollution and at its peak can be up to 560 times higher.” - Researched by Clean Air Day.

The following strategies can improve air quality, minimise damp and mould risks, and create a healthier environment.
Install Exhaust Fans
Exhaust fans exist to expel indoor air to the outside, removing moisture and pollutants from specific areas like kitchens and bathrooms.
How to Implement
Install exhaust fans in high-moisture areas such as bathrooms and kitchens.
Clean the fans regularly to prevent dust buildup, which can restrict performance.
Run the fan during and after activities that generate moisture, like showering or cooking.
Benefits
If your bathroom mirrors frequently fog up after showers, installing a bathroom exhaust fan, such as a Mechanical Ventilation with Heat Recovery (MVHR), will significantly reduce condensation and improve the air quality.
Use Natural Ventilation
Natural ventilation involves using natural forces, like wind and temperature differences, to circulate air through your home. It is energy-efficient and cost-effective.
How to Implement
Open windows on opposite sides of the home to allow a breeze to pass through.
Open windows during colder parts of the day, like early morning or late evening, to avoid bringing in hot air.
Benefits
Opening windows on both the north and south sides of your house during the early mornings will create a pleasant airflow, reducing reliance on air conditioning.
Install Ventilation Grilles
Ventilation grilles are openings that allow air to move between rooms, helping to balance indoor air pressure and improve circulation.
How to Implement
Place grilles in rooms that tend to retain heat or moisture, such as utility rooms.
Choose grilles that match the room size and ventilation needs.
Example
If your home has a central heating system, installing ventilation grilles in all interior doors will improve airflow and make your heating system better.
Use Dehumidifiers
Dehumidifiers remove excess moisture from the air, preventing damp and mould, especially in humid environments.
How to Implement
Use dehumidifiers in any area prone to high humidity.
Adjust the humidity level to approximately 30-50% for optimal comfort and health.
Benefits
If you are finding your home feels damp. Consider introducing a dehumidifier. You may notice a marked decrease in moisture-related problems, such as mould on walls.
Regular HVAC Maintenance
Heating, ventilation, and air conditioning (HVAC) systems help maintain indoor air quality. Regular maintenance ensures they function efficiently.
How to Implement:
Change air filters every 1 to 3 months.
Schedule annual inspections with a qualified tradesperson.
Benefits
If you notice that your HVAC system is not heating evenly, having a professional inspect the system's efficiency will noticeably improve the indoor air quality.
Positive Input Ventilation (PIV)
Positive Input Ventilation systems work by introducing fresh air into the home from the outside.
How to Implement:
Position the PIV unit in a central area, often in the loft or hallway, to distribute air evenly throughout the home.
Look for a PIV system that matches your home’s size and specific needs.
Clean the system’s filters every few months to maintain airflow and efficiency.
Keep an eye on humidity and condensation levels to gauge the system’s impact, especially in winter months when ventilation needs are highest.
Benefits
Having a PIV system installed in your home, you should notice a reduction in humidity levels, condensation and dampness, especially in older properties.
Create a Ventilated Loft
A well-ventilated loft helps regulate temperature and moisture levels, prolonging the life of your roof and improving overall home ventilation.
How to Implement
Use ridge vents or soffit vents to allow air to circulate.
Ensure good insulation to prevent heat and moisture from accumulating.
Benefits
If your attic has condensation, installing ridge vents in your loft can reduce moisture buildup and prevent further damage by allowing a steady flow of fresh air.
Mechanical Extract Ventilation (MEV)
Mechanical Extract Ventilation continuously supplies and extracts air at a low rate, removing stale and moist air from wet rooms like bathrooms and kitchens.
How to Implement
Choose the Right MEV System:
Centralised MEV: Ideal for whole-home extraction, with ducts leading from each room to a single fan unit. This setup is efficient for larger homes.
Decentralised MEV (dMEV): Individual units in specific rooms, like bathrooms or kitchens. This is more common in smaller homes or apartments.
Decentralised Mechanical Ventilation Heat Recovery (dMVHR): Ideal when energy-efficient heat recovery is required on a room-by-room basis.
Focus on high-moisture areas such as bathrooms, kitchens, and utility rooms.
Centralised MEV systems require ductwork from each extraction point to the central fan unit, often routed through the ceiling or walls.
The MEV fan unit is usually installed in a loft space, utility room, or cupboard.
Regularly check and clean filters to maintain airflow efficiency.
Benefits
Introducting MEV, especially in closed spaces, can make a notable difference in air quality, helping reduce moisture, odours, and pollutants.
Use Air Purifiers
Air purifiers can remove pollutants and allergens from the air, complementing natural ventilation methods.
How to Implement
Use in bedrooms or living areas where you spend the most time.
Choose air purifiers with HEPA filters for maximum efficiency.
Benefits
If you introduce air purifiers to your home, alongside regular ventilation practices, you may notice allergy symptoms start to improve.
Seal Duct Leaks
Leaky ducts can lead to energy loss and poor air quality. Sealing them improves efficiency and helps maintain balanced airflow.
How to Implement
Check ducts for visible gaps or loose connections.
Hire a technician to seal leaks with mastic or metal tape.
Benefits
After noticing high utility bills, you might discover leaky ducts. Sealing them could lead to noticeable savings and better air distribution throughout the house.
Use Ventilated Appliances
Certain appliances, like tumble dryers, produce moisture and should be vented to the outside to prevent indoor humidity.
How to Implement
Inspect vents for blockages or lint buildup.
Ensure appliances like dryers are correctly vented outside.

Benefits
In an apartment with a dryer venting indoors, you might encounter dampness. Redirecting the vent outdoors can eliminate the problem.
Regular Home Inspections
Regular inspections can identify potential ventilation issues early, preventing expensive repairs and improving air quality.
How to Implement
Arrange for a professional inspection every few years.
Regularly check for signs of mould, leaks, or blocked vents.
Benefits
Performing regular checks can help you discover early signs of mould, such as, in a wardrobe. Addressing it immediately can prevent a larger issue from developing.
How much does it cost to make your home ventilation better?
Opening windows and trickle vents come at no cost.
Regular maintenance of kitchen and bathroom extractor fans is inexpensive and can help prevent more serious and expensive issues.
A new extractor fan in the kitchen or bathroom could expect you to spend between £100 to £300 plus, for the fan and installation.
A PIV or MEV system might range from £500 to £1,000 plus, including installation, but they offer low running costs.
For an MVHR system, costs can reach thousands, with estimates between £2,000 and £9,000 plus, depending on your home's size, the desired system, and the installation complexity.
How to Improve Ventilation in Social Housing
There are simple ways to make ventilation better in your rental property without needing your landlord's involvement:
Ensure extractor fans are cleaned frequently.
Keep bathroom and kitchen windows open while in use.
Regularly open other windows to promote airflow; for instance, open your bedroom window for 15 minutes upon waking.
Always use the provided extractor fans in the kitchen and bathroom when the spaces become steamy.
If you suspect that the ventilation system in your rented space is malfunctioning, reach out to your landlord to request an investigation and necessary repairs.
