Builders risk having sites shut down immediately if they fail to comply with a new ban on the dry cutting of engineered stone, the Federation of Master Builders (FMB) has warned, as the Health and Safety Executive (HSE) launches a major inspection drive targeting more than 1,000 sites.

The HSE has declared dry cutting of engineered stone, including popular quartz worktops, unacceptable due to the dangerous levels of silica dust it releases, which can cause silicosis, an incurable and potentially fatal lung disease.

Inspectors are now actively targeting both construction sites and fabrication workshops. Any firm found breaching the rules faces an instant Prohibition Notice, stopping work on the spot.

The FMB says many small builders may be unaware of the scale of the crackdown or the severity of the consequences, with demand for engineered stone continuing to rise as more homeowners renovate.

Brian Berry, Chief Executive of the Federation of Master Builders, said:

“If you’re caught cutting engineered stone dry, your site could be shut down immediately. This is about preventing life-threatening illness – but it also puts huge pressure on small firms who may not know that the rules have changed. The message is: comply now or risk facing the consequences. There is support for our members on our website. Silicosis is entirely preventable, yet it is still cutting lives short in construction. We have seen the devastating impact of exposure to hazardous materials, with people losing their chance at a healthy retirement due to diseases like mesothelioma. These are avoidable tragedies. No one should be put at risk just for doing their job.”

 

The FMB is also warning of the financial fallout. For small firms, a site shutdown can trigger missed deadlines, broken contracts and significant financial penalties, costs that can quickly spiral.

Builders are being urged to act immediately and not rely on outdated practices. Even short periods of dry cutting can generate dangerous levels of airborne silica dust.
