In a rush? Key takeaways for site managers
- The trend: Rising consumer demand for quartz and quartzite worktops has put a spotlight on respirable crystalline silica (RCS) dust.
- The rule: The Health and Safety Executive (HSE) has banned dry cutting of engineered stone. On-tool water suppression or compliant extraction is a mandatory legal requirement under COSHH.
- The risk: Government inspectors are visiting more than 1,000 sites and fabricators. Non-compliance risks an immediate site shutdown.
- The support: FMB members can access business templates, a dedicated Health and Safety helpline, and our Safety Plus package to help manage risk.
As homeowners choose to improve rather than move, home renovations are booming across the UK. Influenced by social media renovators, they’re increasingly demanding luxury finishes, with quartz and quartzite worktops topping the wish lists for big-ticket kitchen makeovers. Because engineered stone gives clients a premium look at a more cost-effective price point than natural marble, it has quickly become a trend that keeps our order books full.
But behind the popularity of these sleek kitchen worktops lies a severe health risk that has put the construction industry directly in the media spotlight. High-profile national coverage has highlighted growing calls for a total ban on quartz worktops due to the dangers faced by the tradespeople cutting them.
The dust created when cutting, drilling, and shaping engineered stone releases Respirable Crystalline Silica (RCS) – an invisible, toxic dust. Inhaling even tiny amounts of silica dust causes silicosis, an incurable, aggressive lung disease that is entirely preventable.
Silica dust enforcement: The 2026 HSE crackdown
Because of these severe risks, the HSE has issued strict new guidance. The Health and Safety Executive (HSE) has officially declared that dry cutting of engineered stone is unacceptable.
If your projects involve stone fabrication, composite hearths, engineered stone tiles, or on-site adjustments, you must use on-tool water suppression or extraction systems that comply with the Control of Substances Hazardous to Health (COSHH) regulations.
This isn't a minor policy change. To ensure compliance, government inspectors are launching an aggressive national inspection drive across England, Scotland and Wales (different rules may apply under the Health and Safety Executive Northern Ireland). The HSE is actively visiting more than 1,000 fabrication workshops and construction sites across Great Britain to crack down on poor practices.
At the Federation of Master Builders (FMB), we believe this enforcement protects the reputation of the entire trade. Rogue builders who cut corners aren't just endangering lives – they are undercutting professional, high-quality businesses that invest in the right safety equipment.
FMB members are dedicated to raising standards across their businesses, including on safety management. It’s vital that all builders understand the risks associated with the materials they are using. Respiratory diseases such as silicosis and mesothelioma are entirely preventable, yet they still cut lives short. I’ve seen first-hand the impact asbestos exposure can have, with relatives missing out on a happy retirement because of mesothelioma. It’s a brutal way to end a hard-working life, but one that safety precautions can prevent. Understanding the new HSE standards and putting the right controls in place can save lives. Nobody should be put at risk at work. Let’s make sure everyone gets home safe.”

Shortcuts risk long-term damage
A common myth on busy domestic building sites is that a quick, two-minute on-site trim to make a backsplash or slab fit won't hurt. The reality is that airborne silica dust does not care how short the job is.
Failing to comply isn't just a safety risk; it’s also a devastating financial risk to your cash flow. If an HSE inspector catches anyone dry cutting on your watch, they will issue an immediate Prohibition Notice. This shuts down your entire site instantly. For an SME builder, a delayed handover means broken client contracts, lost referral business, and daily delay penalties that can quickly wipe out your profit margins. Investing in proper wet-cutting kits or hiring extraction tools costs a fraction of a project's budget.
What to ask your stone supplier today
Don't get caught out by unverified materials. Copy and paste this short script into an email to send to your fabricators or suppliers right now:
'Hi [Supplier Name], we are updating our site risk assessments for upcoming projects in line with the latest HSE silica dust regulations. Can you please confirm the exact percentage of respirable crystalline silica (RCS) in the stone slabs we have on order and provide the safety data sheets? If your team is handling the installation, please share your dust-free method statement with us as well.'
Four practical steps to protect your team and stay compliant
Keeping your site safe from silica dust doesn't need to be a hassle. Follow these four essential steps to stay on the right side of the law:
- Check the material: Always check the silica content of your ordered stone and swap to low-silica alternatives where possible.
- Ban dry cutting completely: Ensure any adjustments use integrated water suppression or specialized M-class vacuum extraction to eliminate dust clouds.
- Provide correct RPE: Standard nuisance dust masks will not protect lungs from RCS. You must provide appropriate Respiratory Protective Equipment (RPE), and your team must pass proper Face Fit testing.
- Set up health surveillance: If your employees regularly work with silica-heavy materials, you have a legal duty to provide regular health monitoring.
How FMB members are tackling silicosis
We’ve got our own team tightly sorted when it comes to silica dust, but our job doesn't end with our own payroll. As principal contractors, we take absolute responsibility for the entire project -including what happens with off-site fabrications. We can’t just turn a blind eye when a subcontractor tries to dry-cut masonry on our watch. My advice to other main contractors is simple: accept full accountability. We have to enforce the same uncompromising standards for external trades as we do for our own guys. If we don’t actively police the whole site, we’re failing the industry.”
The highlighting of the dangers of silica dust has been around for a while but not sufficiently emphasised in construction or even to the wider public. The HSE and professional organisations emphasis is really important and timely to avoid further injury and ultimately death by an awful and slow debilitating condition often leading to death. When we think about how simple measures can prevent this it’s a no brainer yet we all to often miss these important elements in day to day work pressures. Checking the equipment you use and the protections you and your people have personally provided is an easy way to make protecting those you work alongside as well as yourselves. Take a moment to consider what old age looks like and take a second to protect the old age you want rather than end up with the old age you’ll utterly regret.”
Silica dust is starting to feel like the new asbestos: not because it is the same material, but because it has the same uncomfortable pattern. It is invisible, easy to underestimate, and often only taken seriously once the damage has already been done. The risk is not always obvious to clients, designers or even some people on site, which is exactly why it needs to be managed early. For us, working safely with engineered stone means looking at the material, the method and the contractor’s controls before the work starts. If cutting can be avoided, avoid it. If it cannot, water suppression, extraction, RPE and proper COSHH controls are non-negotiable. Nobody should be paying for a finished surface with their lungs.”
The bigger picture: Managing all site hazards
While silica dust is currently making headlines, it isn't the only invisible danger on a build. General wood dust, gypsum particulates, and historic materials like asbestos all require the same strict approach to safety.
It's important to check the HSE guidelines for immediate compliance steps. Remember that if you are working on older properties or domestic refurbishments, checking the age of the building and verifying asbestos risks before work begins is a vital legal duty that protects your clients, your team, and your business.

FAQs about silica dust and silicosis
Is engineered stone or quartz banned in the UK?
No, quartz worktops and engineered stone are not currently banned in the UK. However, following media coverage surrounding calls for a ban on manufactured engineered stone due to health risks, the Health and Safety Executive (HSE) has banned the practice of dry cutting these composite materials. This specific restriction applies to man-made engineered stone surfaces, composite hearths, and quartz tiles. All cutting and shaping on-site must use strict dust control measures like water suppression or on-tool extraction.
What is the legal limit for silica dust exposure on a UK construction site?
Under COSHH regulations, the workplace exposure limit (WEL) for respirable crystalline silica (RCS) is extremely strict: 0.1 mg per cubic metre averaged over an 8-hour shift. This has been the legal standard since 2006. Because this invisible dust is too fine to see with the naked eye, relying on visual checks isn't enough to stay compliant.
For the statutory guidance and breakdown of employer obligations under COSHH regarding silica, see the HSE Guide on Control of Exposure to Silica Dust.
Can I use a standard dust mask for cutting quartz or engineered stone?
No. Standard nuisance dust masks or lower-grade face masks do not filter out microscopic respirable crystalline silica (RCS) particles. Employers must provide high-efficiency Respiratory Protective Equipment (RPE) suitable for silica dust, and every worker must undergo formal Face Fit testing to ensure the equipment forms a complete seal.
Does water suppression completely eliminate silicosis risks?
Water suppression dramatically reduces the amount of airborne dust, but it must be used correctly to be fully effective. The water feed must be continuous, and the resulting slurry must be cleaned up properly before it dries out and turns back into inhalable dust.
What happens if an HSE inspector finds dry cutting on my site?
If an inspector observes dry cutting of engineered stone or materials containing silica, they will issue an immediate Prohibition Notice. This stops that specific work activity – and potentially shuts down your entire site – until compliant dust control equipment and correct RPE are put in place.
Where can small building companies get compliant silica risk assessment templates?
FMB members can access industry-approved risk assessment and COSHH templates directly through the FMB Document Library. For comprehensive support, members can upgrade to our Safety Plus package for £8.21 a month + VAT to access specialized BSG RAMS software, which contains 115 pre-populated templates designed specifically for construction companies.
