Expert help choosing the right chimney cowl

Consider the chimney’s use, fuel type, chimney-pot shape and diameter, fixing method and the problem you are trying to solve. Common requirements include stopping birds, limiting rain entry, reducing downdraught or capping a disused chimney. Contact us with measurements and photographs when you need help narrowing down the options.

The required measurement depends on the product and fixing method. It may be the outside diameter of a round chimney pot, the internal opening, the width of a square pot or the diameter of a flue liner. Tell us which product you are considering and supply several clear measurements where possible.

Yes. Photographs can be useful when identifying the type and shape of chimney pot or an existing fitting. You can send photographs through WhatsApp. Please also include measurements, fuel type and details of the problem, as a photograph alone may not establish product compatibility.

A purpose-designed chimney bird guard or bird-and-rain guard may help prevent birds and nesting debris from entering the chimney. The correct model must also be suitable for the chimney’s fuel type and dimensions. Do not simply block or seal an active chimney.

Anti-downdraught cowls are designed to help reduce wind entering the chimney and forcing smoke or fumes back towards the room. However, downdraught can have several causes. Persistent smoke or fume problems should be assessed by a suitably qualified chimney or heating professional before a product is selected.

A cap specifically intended for a disused chimney should not be installed on a live flue or active appliance. Active chimneys require an appropriately ventilated terminal that is compatible with the appliance, fuel and flue system.

No. Products can be approved or intended for different applications, including gas, oil, solid fuel, wood, coal or multi-fuel use. Always check the product description and obtain professional advice when you are unsure.

Some cowls use relatively straightforward strap or bolt fixings, but working at roof height carries serious risks. Fuel compatibility, ventilation and safe access must also be considered. We recommend using a competent installer or chimney professional, particularly for active flues and heating appliances.

Yes. Use the contact form or telephone us and include your order number, the name used when ordering and a concise description of the help you need. This will make it easier for us to locate the order.

Stop using the appliance, ventilate the property and seek urgent advice from a suitably qualified heating, chimney or gas professional. A chimney cowl should not be treated as a substitute for investigating a potentially dangerous flue, appliance or ventilation fault.
