Cast iron hoppers do far more than connect guttering into a downpipe. On traditional buildings, they become part of the architecture itself. Positioned beneath roof valleys, parapet outlets, or along prominent elevations, hopper heads help manage concentrated rainwater flow while adding real depth and character to the façade.
At Cast Iron Warehouse, we supply genuine Alumasc Apex Heritage cast iron hoppers designed to match traditional cast iron guttering systems perfectly. Manufactured using authentic sand cast methods and produced to BS460 standards, the Apex range combines heritage detailing with the long-term durability expected on modern restoration and specification projects.
This range includes decorative fluted hopper heads, flat back hoppers, corner hoppers, and rectangular cast iron rainwater hoppers designed to work alongside both round and rectangular cast iron downpipes. These profiles are widely specified across listed buildings, churches, period homes, conservation work, and architectural developments where standard plastic rainwater fittings simply do not suit the building. If you need inspiration, have a look at our gallery here.
Unlike cast iron effect hopper heads, genuine cast iron creates a far more authentic finish once installed. The weight, detailing, and deeper cast texture give the system proper architectural presence, especially when paired with traditional cast iron guttering and downpipes.

Cast Iron Rainwater Frequently Asked Questions
How Quick Is Delivery?
How Quick Is Delivery?
Popular painted black cast iron guttering sizes are typically available for next working day delivery across the UK when ordered before 11:30am, subject to stock availability.
Primed systems are stocked across selected sizes, while custom RAL powder coated cast iron guttering is usually supplied within 7–10 working days.
What Makes Apex Heritage Different From Cheaper Cast Iron Systems?
What Makes Apex Heritage Different From Cheaper Cast Iron Systems?
We think the consistency is noticeably better. Apex Heritage cast iron guttering is manufactured using traditional sand cast methods alongside modern quality control standards, giving cleaner alignment, more reliable fitment, and a far better painted finish compared with lower-grade imported systems.
What Size Cast Iron Guttering Do I Need?
What Size Cast Iron Guttering Do I Need?
For most standard residential properties, 115mm (4½”) Half Round cast iron guttering is the most commonly used size. Larger roofs, commercial buildings, or areas with heavier rainfall may benefit from 125mm or 150mm systems. If you're replacing existing guttering, matching the current profile and outlet size is usually the safest option.
Is Cast Iron Better Than Cast Iron Effect Plastic Guttering?
Is Cast Iron Better Than Cast Iron Effect Plastic Guttering?
They’re completely different products really. Plastic cast iron effect guttering is lighter and cheaper upfront, but genuine cast iron is significantly stronger, longer lasting, and far more authentic visually. Proper cast iron guttering can last well over 40 years and suits heritage buildings far better than imitation systems.
Are Custom Colours Available?
Are Custom Colours Available?
Yes. Custom RAL colour cast iron guttering is available for heritage and architectural projects requiring a more bespoke finish. These systems are professionally powder coated in the UK with typical lead times of 7–10 working days.
How Heavy Is Cast Iron Guttering?
How Heavy Is Cast Iron Guttering?
Cast iron guttering is substantially heavier than plastic or aluminium systems, which is part of why it lasts so long. Proper bracket spacing and secure fixing into suitable surfaces is important for long-term performance.
How Long Does Cast Iron Guttering Last?
How Long Does Cast Iron Guttering Last?
