Luckily, fitting a chimney cowl isn't too difficult a job. This project will usually take less than an hour and won’t be too expensive. Most roofers should be able to fit a chimney cowl. However if you need any other work doing on your roof, it may be more cost effective to get both jobs done at the same time.

What is a chimney cap?

Similar to a chimney cowl, a chimney cap sits at the top of your chimney, preventing animals, rain and smoke from entering your home. Chimney caps and chimney cowls have differences in their structure but perform similar functions.

Once you make the wise choice to add a chimney cowl or cap to your chimney, you’re probably wondering how much to budget for this job. Well, the amount you pay will depend on a few factors including:

• Size of chimney - Larger chimneys will need larger cowls, this can increase the price you pay.

• Type of cap or cowl - There’s a wide range of chimney caps and cowls available, all of which have different prices.

• Quality of cap or cowl - Choosing a high quality chimney cowl or cap means a longer lifespan and more effective performance. However, the higher the quality, the higher the cost.

• Accessibility - If your chimney is difficult to access, this may increase the cost of labour for this job.

• Scaffolding - If scaffolding is needed to fit your chimney cowl, this will push up the cost of installation by around £125.

If you’re considering fitting a chimney cowl yourself, first consider whether it’s safe for you to climb onto your roof. This is a risky job, so if you struggle with mobility or don't have a head for heights, we’d recommend speaking to a professional chimney cowl fitter. That way you can save time, energy and a lot of worry.

Wondering how to fit a chimney cowl? Well, different types of chimney cowl are fitted in different ways. For example, a weathering cap chimney cowl is attached to the end of your chimney flue system, resting on top of the chimney. Alternatively, pot hanging cowls can be installed on top of your chimney and held in place using three straps.
