Shop Chimney Cowls Read the FAQsWhat Is a Chimney Cowl?
A chimney cowl is a specially designed fitting installed at the top of a chimney pot or flue. Depending on the design, it can help protect against rain, birds and debris, improve airflow, and reduce the effects of wind-related downdraught.
For UK homeowners, choosing the correct chimney cowl is particularly important because exposed roofs, strong winds and wet weather can all affect chimney performance.

- Reduce rain entering the flue
- Improve chimney ventilation and airflow

Common Chimney Problems a Cowl Can Help Solve
Smoke Blowing Back into the Room
If smoke enters the room rather than travelling safely up the chimney, wind-induced downdraught may be one possible cause. An anti-downdraught chimney cowl can help stabilise airflow around the chimney top.
Birds Nesting in the Chimney
Birds such as jackdaws can nest in chimneys, potentially causing blockages and ventilation problems. A chimney bird guard or bird guard chimney cowl helps prevent birds entering the flue while maintaining airflow.
Rain Entering the Chimney
Excess moisture can damage chimney liners, masonry and fireplace components over time. A suitable chimney rain cap or rain and bird guard can help reduce water ingress.
Protecting a Disused Chimney
An unused chimney should normally remain ventilated rather than being completely sealed. A disused chimney cap can help protect against rain, birds and debris while allowing air movement through the flue.
