Chimney Gallows Brackets: A Practical Guide
Removing a chimney breast is a common part of modern renovations, loft conversions, and structural alterations in older UK homes. When the internal chimney breast is taken out but the external stack remains, the remaining masonry must be supported safely. This is where chimney gallows brackets become essential.
At Buildware, we supply robust, red‑oxide‑painted chimney gallows brackets in two sizes — 380×380×50mm and 380×380×70mm — giving builders and homeowners a reliable, structurally sound solution.
What Are Chimney Gallows Brackets?
Chimney gallows brackets are heavy‑duty steel brackets designed to support the remaining chimney stack when the internal breast is removed. They form a triangular support system that transfers the load into the party wall.
They are commonly used in:
- Chimney breast removal
- Loft conversions
- Structural alterations in older brick‑built homes
- Situations where full chimney stack removal isn’t possible
When Do You Need Gallows Brackets?
Whether gallows brackets are suitable depends on several factors:
- The thickness and condition of the party wall
- The weight of the remaining chimney stack
- Whether the chimney is shared with a neighbouring property
- Local building control requirements
- Structural engineer recommendations
Gallows brackets are widely accepted by UK building control when the wall is strong enough and meets the required thickness. Always confirm with a structural engineer before installation.
