The integral rain cap helps reduce water entry, and the supplied stainless-steel strap fixing provides a secure, straightforward installation on a suitable round chimney pot.
- Fits round chimney pots from 150mm to 250mm internal diameter
- Maximum recommended chimney-pot external diameter: 285mm
- Integral mesh birdguard helps prevent wildlife and debris entry
- Built-in rain cap helps minimise rainwater entering the flue
- Stainless-steel strap fixing kit supplied
- Gas, oil and solid-fuel configurations available
Stop birds, nesting material and rain from entering your chimney
An open chimney pot can provide an inviting nesting place for birds and a route into the flue for squirrels, leaves and other debris. Blockages can interfere with ventilation, restrict the safe passage of smoke and gases, create unpleasant smells and increase the need for avoidable chimney maintenance.
The Brewer Rain and Birdguard uses a protective wire mesh around the terminal to discourage wildlife and larger debris while maintaining an open route for flue gases. Above the mesh, an integral rain hat helps shield the chimney opening from direct rainfall and snow, reducing the amount of moisture entering the stack.
This practical rain and birdguard chimney cowl is suitable for both live and redundant chimneys when the correct model is selected for the appliance, fuel and flue system. Its round profile and stainless-steel strap fixing make it a popular choice for standard round chimney pots across UK homes.

Reliable chimney protection without restricting normal ventilation
A well-designed birdguard should deter unwanted entry, reduce rain ingress and still leave adequate space for smoke, fumes and air to move through the chimney terminal.
Prevents bird entry
The integral wire mesh forms a physical barrier that helps stop birds from nesting inside the chimney or falling into the flue.
Discourages squirrels and pests
The enclosed guard helps prevent larger wildlife from accessing a warm, sheltered chimney and causing disruption or blockage.
Reduces rain ingress
The fixed rain hat shelters the chimney opening and helps reduce the volume of rain and snow entering the flue from above.
Helps avoid blockages
Keeping leaves, twigs, nests and debris out of the chimney supports safer ventilation and reduces preventable obstruction.
Secure strap fixing
The supplied stainless-steel strap wraps around the chimney pot and tightens securely without relying on adhesive or mortar.
Choice of finishes
Select Natural, Terracotta, Buff Stone or Black to complement traditional brickwork, rendered stacks and different roof finishes.
Choose by fuel, material and colour
The options at the top of this product page allow you to specify the version suitable for your chimney system and preferred appearance.
Select the fuel type
Choose the version intended for gas, oil or solid fuel. Mesh and construction requirements vary by appliance and fuel, so select the option that matches your installation.
Select aluminium or stainless steel
Aluminium provides a light, corrosion-resistant solution for suitable applications. Stainless steel is recommended for solid fuel, coal and smokeless fuel, where heat and corrosive deposits can be more demanding.
Select the finish
Choose from Natural, Terracotta, Buff Stone or Black to coordinate the chimney cowl with your chimney pot, roof covering and property style.
Match the chimney cowl to the appliance below
The correct terminal depends on the fuel, appliance, chimney type and required mesh configuration. Always select the model specifically intended for your system.
Gas installations
Choose the gas-fuel version. Gas terminals require an appropriate fine-mesh configuration and should be specified for the appliance and flue by a competent professional.
Oil installations
Select the oil-fuel option shown on the product page. Confirm compatibility with the appliance, flue diameter and manufacturer requirements before fitting.
Wood, coal and solid fuel
Choose the solid-fuel version. Stainless steel is recommended for coal and smokeless fuels because these applications can expose the cowl to greater heat and more corrosive deposits.

Correct sizing is essential for a secure strap fit and safe clearance around the flue outlet.

Confirm compatibility
Check the fuel option, internal diameter, external pot diameter and chimney-pot shape before installation.
Inspect and sweep
Arrange for the chimney or flue to be inspected and swept so it is clear, safe and ready for the terminal.
Position the cowl
Place the birdguard centrally over the chimney opening with the legs seated evenly around the pot.
Tighten the strap
Wrap the stainless-steel strap around the pot and tighten it evenly according to the supplied fitting instructions.

Brewer Rain and Birdguard Chimney Cowl FAQs
Answers to common questions about chimney-pot sizing, fuel selection, bird protection, rain entry and strap-fixing installation.
What does the Brewer Rain and Birdguard Chimney Cowl do?
It helps prevent birds, squirrels, nesting material, leaves and larger debris from entering the chimney. Its integral rain cap also helps reduce the amount of direct rainfall and snow entering the flue while leaving space for smoke and gases to escape.
What size chimney pot does this birdguard fit?
It is intended for standard round chimney pots with an internal diameter of approximately 150mm to 250mm, or 6 to 10 inches. The product information also states a maximum external pot diameter of approximately 285mm.
How do I measure my chimney pot?
Measure straight across the internal opening at the top of the pot to obtain the internal diameter. Also measure across the outside of the pot to confirm that the strap and legs can fit. Because roof access is hazardous, measurements should be taken by a competent professional using safe access equipment.
Is the stainless-steel strap fixing included?
Yes. The Brewer Rain and Birdguard is supplied with the stainless-steel strap fixing and associated fittings required for installation on a suitable round chimney pot.
Can this chimney cowl be used on a live chimney?
Yes, provided you select the correct version for the appliance, fuel and flue system and have its suitability confirmed professionally. It can also be used on suitable redundant chimneys.
Is it suitable for gas fires?
A gas-specific version is available. Select the gas option on the product page and have a Gas Safe registered professional confirm compatibility with the appliance and chimney system.
Is it suitable for wood burners and solid fuel?
A solid-fuel version is available for suitable wood, coal and solid-fuel systems. Stainless steel is recommended where higher temperatures and corrosive deposits from coal or smokeless fuels may be present. Always confirm suitability with the appliance and flue requirements.
Should I choose aluminium or stainless steel?
Aluminium is lightweight and corrosion resistant for suitable applications. Stainless steel generally provides greater durability under demanding conditions and is the recommended choice for coal, smokeless fuel and other corrosive solid-fuel applications.
Will the cowl stop all rain entering the chimney?
The integral rain cap substantially reduces direct rain entry, but no open-flue terminal can guarantee that every drop of wind-driven rain will be excluded in all weather conditions.
Will it stop small insects?
The birdguard mesh is designed primarily to deter birds, squirrels and larger debris. It is not an insect screen and will not exclude every small insect.
Does this product cure chimney downdraught?
This product is primarily a rain and birdguard rather than a specialist anti-downdraught cowl. Where smoke or fumes are being blown back into the property, the chimney and ventilation should be assessed professionally and an anti-downdraught cowl may be more appropriate.
Can it fit a square or decorative chimney pot?
This standard model is designed for round chimney pots. Square, crown, bishop and oversized decorative pots may require a different product or a specially adapted cowl. Send photographs and measurements to the team for advice.
Can the chimney still be swept after fitting?
Yes, but access arrangements depend on the chimney, cowl and sweeping method. Tell your chimney sweep that a strap-fixed birdguard is installed so they can advise whether it should be loosened or removed for servicing.
How often should the birdguard be checked?
It should be visually inspected as part of routine chimney maintenance and after severe weather. Solid-fuel systems should be checked for soot or tar accumulation, corrosion, damage and secure fixing in line with professional advice.
Is professional installation recommended?
Yes. Roof work carries a serious fall risk, and chimney terminals must be correctly selected and installed. Use a competent professional with suitable access equipment and relevant knowledge of the appliance and flue.
What colours are available?
The product page provides Natural, Terracotta, Buff Stone and Black finish options. Availability may vary according to the selected fuel type and metal.
How do I order the correct Brewer birdguard?
Return to the product options at the top of this page, select the fuel type, metal and colour, choose the quantity and add the product to your basket. Contact the team before ordering when the chimney-pot measurements or fuel requirements are uncertain.

Very easy fitting – assuming you can get to the chimney top of course! Only just fitted so can’t comment on efficiency but seems well made – and should certainly stop jackdaws from falling down the chimney which is what I bought it for.

The chimney cowl is fine, and was easy to fix. Unfortunately we bought it to stop a leak, which we have discovered is down to damaged flashing. But it offers protection from rain and birds.

Great product at a great price and super fast delivery.
We have all come to expect a purchase acknowledgement email and/or details of despatch and so maybe, that would be my only criticism of this purchase.
I had several orders over a number of weeks and so knew the score after the first batch.
Purchased a number of C-Caps as well and these are proving to be an absolutely brilliant purchase for keeping the heat in and so easy to fit.
