In the wake of evolving fire safety legislation, the specification of internal fixtures has never been more critical. At Post Boxes UK, we prioritise building integrity by offering a range of specialist fire-rated letterboxes and mailboxes designed to meet the most stringent UK Building Regulations and safety standards.

Our certified systems include options that provide up to 120-minute fire integrity (BS 476: Part 22), making them suitable for installation within critical escape routes where fire containment is essential. Additionally, we provide Class O non-combustible solutions, ensuring maximum resistance to flame spread in high-risk environments (BS 476: Parts 6 & 7). These units are specifically engineered to prevent the passage of fire and smoke through the mail aperture, protecting both the building structure and its occupants.

Designed for high-density residential and commercial use, our modular postboxes are fully configurable to suit any project scale. By combining robust fire protection with high-security locking and contemporary design, we ensure that safety compliance does not come at the expense of functionality or aesthetic appeal.

When building safety is paramount, it is essential to specify a solution that is proven to perform under pressure. To view our full range of certified fire-rated systems and technical datasheets, please visit our specialist site at www.fireratedletterboxes.co.uk.
