Ever started a guttering project only to realise you’re short on brackets?
You’re not alone!
One of the most frequently asked questions in gutter installation is: How many downpipe brackets do I actually need?
The right answer depends on the type of guttering system you’re installing, the material, and the size of the downpipe.
Getting this right is crucial—not only for the longevity of your drainage system but also for its structural integrity.
Too few brackets can lead to sagging or even collapse over time. But don’t worry! This guide will walk you through everything you need to know about downpipe brackets, their spacing, and choosing the right size clips for a secure fit.

Why Downpipe Brackets Matter More Than You Think
Here’s why you need to ensure you install the correct number:
- Prevents Sagging & Structural Failure – Over time, heavy rainfall, wind, and even snow can place stress on your gutters. Adequate brackets ensure that your system remains intact.
- Reduces Noise & Vibration – If your downpipe isn’t firmly secured, water flow can cause vibrations, leading to unwanted noise and eventual loosening of the pipes.
- Ensures Proper Drainage – Without enough support, the alignment of your downpipe can be thrown off, causing improper water flow and potential blockages.
- Aesthetic & Compliance Benefits – A poorly installed downpipe with visible sagging or misalignment can impact your property’s visual appeal. In some cases, local building regulations may also require correct bracket spacing.
How Many Brackets Per Length of Guttering?
The number of brackets you’ll need depends on the type of metal guttering you have.
Below is a breakdown for different materials:
Galvanised Steel, Copper, Zinc & Stainless Steel Guttering
- Fascia Brackets: Position every 915mm (3 feet) apart.
- Minimum Per Gutter Length: At least 3 brackets per length.
- Angles & Outlets: Add one extra bracket per angle or outlet.
And How Many Downpipe Clips?
- For a 3-metre downpipe, use 2 clips.
- For each additional drop, add one extra clip.
🔧 Pro Tip: Always match the downpipe clip size to the pipe size for a secure fit! For example, use:
- 60mm clips for 60mm downpipes.
- 80mm clips for 80mm downpipes.
-
100mm clips for 100mm downpipes.
Contemporary Aluminium Guttering (SnapIT Half Round & Moulded)
- Fascia Brackets: Position every 750mm (2.5 feet) apart.
- Minimum Per Gutter Length: At least 4 brackets per length.
- Angles & Outlets: Add one extra bracket per angle or outlet.
How Many Downpipe Clips?
- For a 3-metre downpipe, use 2 clips.
- For each additional drop, add one extra clip to secure the final 1.5 metres.
💡 Note: Other contemporary aluminium ranges follow the same rules as galvanised steel, with brackets every 915mm and at least 3 per length.

Cast Aluminium Guttering
Aluminium guttering is a popular choice for those looking to combine traditional aesthetics with modern performance.
Known for its strength, corrosion resistance, and classic appearance, this guttering type is commonly found on period properties, heritage buildings, and contemporary homes alike.
But just like any other system, it requires the right number of brackets and clips to stay secure and functional. Here’s what you need to know about installing cast aluminium gutter brackets and downpipe clips correctly:
- Fascia Brackets: Use at least 2 brackets per 1.83m gutter length.
- Angles & Outlets: Add one extra bracket per angle or outlet.
Downpipe Fixing for Cast Aluminium
-
Heritage pipes usually come with cast ears, but the final pipe drop will need:
- An eared shoe to secure the bottom, or
- A downpipe clip if it discharges straight into a gully.
🚧 Mounting Tip: Downpipe clips for cast aluminium must be secured using specialised downpipe screws for added durability.

Cast Iron Guttering
If you’re after unmatched strength and a heritage aesthetic, cast iron guttering is the gold standard.
Often seen on historic buildings and period homes, it provides a robust, long-lasting solution that can withstand extreme weather conditions for decades.
However, due to its heavy weight, proper support is crucial. That’s why getting the right number of brackets and securing them correctly is essential for a safe, stable, and efficient drainage system. Here’s how to do it right:
- Fascia Brackets: Use at least 2 brackets per 1.83m length.
- Angles & Outlets: Add one extra bracket per angle or outlet.
Downpipe Fixing for Cast Iron
- Cast iron downpipes usually come with cast ears.
- The final drop requires either:
- An eared shoe, or
- A downpipe clip if it connects directly to a gully.
🔩 Installation Tip: Use cast-iron-specific screws to ensure a firm and lasting grip when securing downpipe clips.
How to Choose the Right Downpipe Clip Size
A common mistake in gutter installations is using the wrong size clip. Here’s how to match them correctly:
- 60mm Downpipes → Use 60mm clips.
- 80mm Downpipes → Use 80mm clips.
- 100mm Downpipes → Use 100mm clips.

FAQs: Your Downpipe Bracket Questions Answered
1. Can I install fewer brackets to save costs?
Not recommended! Reducing the number of brackets increases the risk of sagging and potential damage, leading to higher repair costs in the long run.
2. Should downpipe brackets be installed into brick or render?
For optimal security, always install brackets into brick or solid masonry rather than soft render, which can crack over time.
3. Can I mix different materials for brackets and clips?
While possible, it’s best to use matching materials to avoid galvanic corrosion (especially with metals like zinc and copper).
4. What tools do I need for installing downpipe brackets?
- Cordless drill (for drilling into walls)
- Masonry screws (for secure attachment)
- Spirit level (to ensure proper alignment)
-
Measuring tape (for accurate bracket spacing)
