Collaborative Reporting for Safer Structures UK

[edit] Introduction

Collaborative Reporting for Safer Structures UK (CROSS-UK) is a collaborative body that compiles and publishes free safety information for built environment professionals. Formerly known as the Confidential Reporting on Structural Safety, CROSS was founded in 2005 as a system for the collation of data on matters of concern relating to structural safety.

CROSS operates internationally; following in the footsteps of CROSS-UK, the IStructE launched in Australia with CROSS-AUS in 2018 and then in 2019 the network grew to the US with CROSS-US formed by the Structural Engineering Institute (SEI) of the American Society of Civil Engineers (ASCE).

The UK government 'Construction Products Reform Green Paper 2025' published 26 February 2025, defines Collaborative Reporting for Safer Structures UK (CROSS-UK) as 'A confidential reporting system which allows professionals working in the built environment to report on fire and structural safety issues. These are then published anonymously to share lessons learned, create positive change, and improve safety.'

On 10 July, 2025 the Health and Safety Executive (HSE), acting in its role as the Building Safety Regulator (BSR), formally appointed CROSS-UK (Collaborative Reporting for Safer Structures) as the official Voluntary Occurrence Reporting System (VORS) for structural and fire safety until at least 2028, following a competitive tender process. Operating independently of both the regulator and government, CROSS-UK has been running the system on an interim basis since April 2023 and is trusted across the industry for its ability to support cultural change, risk recognition, and improved public safety through anonymous reporting, expert review, and shared learning. CROSS-UK provides a secure, confidential channel for professionals to report safety concerns and near-misses—strengthening building safety in th post-Grenfell regulatory framework under the 2022 Building Safety Act

[edit] Background

The establishment of the CROSS safety reporting system was based on work by the Standing Committee on Structural Safety (SCOSS). In 2012, SCOSS and CROSS were officially aligned under the name Structural-Safety.

In 2018, CROSS was incorporated into the recommendations of the Hackitt report. The system was specifically mentioned under recommendation 1.4c, which states, ‘For all other buildings, the current CROSS scheme should be extended and strengthened to cover all engineering safety concerns and should be subject to formal review and reporting at least annually.’

After discussions between Structural-Safety and the Ministry of Housing, Communities & Local Government (MHCLG), funding for CROSS-UK was increased in 2020 to include fire safety in compliance with the aforementioned recommendations in the report. The CROSS system expanded in 2021 to include structural safety as well as fire safety and all three entities - Structural-Safety, SCOSS and CROSS - are united to operate under a new name, Collaborative Reporting for Safer Structures (CROSS).

[edit] Importance of safety reporting

The new name for the organisation is meant to illustrate the connection and to respond to the overlap - both professional and physical - between structural safety and fire safety. CROSS will continue to provide built environment professionals the opportunity to make confidential reports when they witness either type of safety issue.

The information collected in the reports is confidential, but it is shared with a panel of expert volunteers who review and comment on findings to provide additional insight into incidents. In addition to educating others about the importance of identifying and relaying structural safety issues and building incidents (such as near misses), reports are intended to:

• Promote culture change.
• Share lessons learned.
• Find issues that could foreshadow risk.
• Identify shortfalls or vulnerabilities.
• Improve competency through training.
• Support regulatory activities.
• Inform professional education activities.
• Create proactive attitudes about preventing safety risks.
