When choosing your cowl it is always worth keeping in mind how your chimney sweep will clean your chimney once the cowl or bird guard has been installed.

Below is a list of cowls that I have come across as my time as a chimney sweep.

Cowls that require removing or being maintained from the roof.

H-Cowls
Spinning Cowls
Powered Cowls

Bird guards that require periodically removing to ensure a clear sweep.

Cone Top Birdguards
Many guards that pushes into the pot may need removing annually or bi-annually depending on your soot quality and quantity. This is to ensure a clear sweep can be performed.

Bird guards that can be swept in situate.

High Top Birdguard
In general, if it has a jubilee clip attaching it to the pot, your burning correctly and you have a good updraught then it usually can be safely swept from the ground.

Cowls for disused chimneys.

The clay hood cowl
This cowl is a vent to stop dampness occurring in you disused chimney stack. Unfortunately  I see this one a lot on live fires, which results in a 'do not use' notice that explains that the clay hood cowl needs removing before she can be signed off.

C-Cap Cowl

Cowls for gas.

GC1 - Gas Cowl
This is the most common terminal for gas appliances

Overview.

It's always worth thinking, “how can my sweep, sweep this?” when purchasing a cowl or bird guard, as by selecting a cowl that's difficult to sweep will in turn cost you more money in the annual maintenance of your chimney.

Always seek advice from a professional to ensure your cowl is suitable for your instillation.
