A Look at Chimney Cowls and Prices

Chimney cowls are fitted to the very top of chimney stacks and they have several uses; they keep rainwater out of the chimney, they reduce wind noise and also help to improve the updraft of the chimney.

Not every chimney will have a cowl on the top, they’re optional but it’s generally considered a best practice to have one fitted.

If you want to know how much it costs to fit one of these cowls, explore the price guide on this page.

Not Sure Which Cowl to Use? Fit a Multi-Purpose Cowl

There are several different types of chimney cowl and historically gas and coal fireplaces would have different cowls fitted.

Nowadays, installers generally fit multi-purpose cowls.

These can be adjusted to fit almost any chimney size and can be used with gas, oil, wood and coal fireplaces as well as disused chimneys that require ventilation and some protection from the elements.

Our price guide below is for the installation of a multi-purpose cowl, they’re slightly more expensive than other cowls but once fitted, you can forget about it.

Cost to Buy a Cowl

Multi-purpose chimney cowls can be found in most roofer’s merchants, some builder’s shops and also online from well-known retailers such as Amazon.

You can expect to pay around £40.00 for a multi-purpose cowl:

How Much Does it Cost to Fit a Chimney Cowl?

It only takes a few minutes to fit a chimney cowl. In fact, it would take longer to get up on the roof than it would to fit the cowl.

The cost to fit a chimney cowl will depend on the height and location of the chimney and whether it can be reached from a ladder or if access scaffold or even a cherry picker is needed.

Our price guide below assumes that the chimney can be reached without a scaffold or hire equipment.

Tips/Advice

The reason we recommend a multi-purpose cowl is because you won’t ever need to change it, even if you swap a gas fireplace for a coal, wood or oil one.

Multi-purpose cowls also contain a metal grille that prevents birds from nesting in the chimney.

What Type Of Tradesperson Installs Cowls?

Roofers often install cowls and some will also own scaffolding and access towers so they might be able to reach the top of the chimney without using the services of an external scaffolding firm, this could save you money if your chimney is very difficult to reach.

Chimney sweepers can also install cowls to most easy-to-reach chimneys.

How to Keep Costs to a Minimum

If you’re planning to have any other roofing repair work done in the future, there’s no point in paying for the erection of scaffolding or access towers twice.

It may make sense to install a chimney cowl at the same time as the other work is completed.

    You omit to refer to cowls specifically designed for capping-off disused chimneys, although in most older properties (pre-1960) the majority of flues are disused and should be protected from the elements etc.. Please see our website. You might be able to source fitting costs via The National Association of Chimney Sweeps? There are also many ‘Customer Reviews’ on the http://www.fluesystems.com website, some of which state fitting cost.

    What does ‘awaiting moderation’ mean?

    I live in West of England and just had a bloke come round who was in the area and he fitted one for £49 all in.

    Can anyone tell me how often a chimney cowl needs to be replaced?
    My landlord fitted a new one a year ago after that the chimney became blackened
    I moved out early June and he has asked me to pay £150 for a new one because of the dirt that has gathered over the last 12 months

      Tell him to go jump off his own roof. The Cowl is a fixture / fitting and therefore it is his responsibility not the tenants.
