Are Quartz Worktops Safe? What the New HSE Rules Mean for Homeowners
You've probably seen the headlines. Quartz worktops. Lung disease. New government rules. And if you're planning a kitchen renovation - or you already have quartz in your home - you may be wondering whether to be worried.
Here's the short answer: homeowners are not at risk. The new rules exist to protect the workers who cut and fabricate stone - not the people who live with it in their kitchens. But the full picture is worth understanding, because it tells you something important about how to choose a kitchen company you can trust.
What Are the New HSE Rules on Quartz Worktops?
The Health and Safety Executive has banned dry cutting of engineered stone and made water suppression tools a legal requirement for fabricators across the UK. HSE inspectors are now carrying out 1,000 nationwide inspections, with factory bosses facing up to two years in prison for non-compliance.
The rules came after a number of stonemasons were diagnosed with silicosis - a serious, incurable lung disease - caused by inhaling silica dust during the cutting and grinding process. One case that made national news was the death of stonemason Marek Marzec, whose family described his passing as entirely preventable. It's a genuine tragedy, and it's right that the industry is being held to a higher standard.
What Is Silicosis and Why Does It Affect Stonecutters?
Silicosis is a lung disease caused by breathing in crystalline silica dust over a sustained period of time. Quartz is one of the hardest minerals on earth and engineered stone worktops - the type sold under names like Silestone, Caesarstone, and Dekton - can contain a very high proportion of silica. When that stone is cut, ground, or polished using power tools without adequate water suppression or respiratory protection, fine silica particles become airborne and can be inhaled deep into the lungs.
The risk exists at the fabrication stage - in the factory or workshop where worktops are cut to size - and during any dry cutting done on site during installation. It is not a risk that comes from having quartz worktops in your kitchen, cleaning them, placing hot pans near them, or living with them day to day.
The Worktop Fabricators Federation has confirmed that the risk is "purely to do with the factory management in the fabrication process" and that there is "no health risk in handling, shipping, installing or using engineered stone worktops."
Is There Any Risk to Homeowners With Quartz Worktops?
No. There are zero recorded cases of silicosis in homeowners with quartz worktops, and there is no scientific evidence of any health risk from living with an installed quartz surface. Leading quartz brands carry independent safety certifications including Greenguard Gold for air quality and NSF certification for food hygiene safety.
Once a quartz worktop is fabricated and installed, it is an inert, sealed surface. Silica particles are only ever airborne during cutting and grinding - processes that should never happen in your kitchen. If a small adjustment needs to be made on site, any responsible installer will do this outdoors, in open air, with full respiratory protection.
Why Do the New Rules Matter If Homeowners Are Safe?
Because the rules draw a clear line between responsible fabricators and those cutting corners - and that distinction matters to you as a buyer, even if you personally face no health risk.
Until now, some small fabrication operations have been processing quartz without water suppression, without adequate ventilation, and without proper respiratory protection for their workers. They have been undercutting compliant businesses on price while putting their employees at serious risk. The new HSE crackdown targets exactly these operators.
What this means in practice: the kitchen company you choose, and who they work with to fabricate your worktops, is now more important than ever. An HSE-compliant fabricator - one using water suppression, proper extraction, monitored air quality, and trained staff - is not just the ethical choice. It's the legal one.
What Should You Ask a Kitchen Company Before Buying Quartz?
When you're choosing a kitchen designer or fitter who offers quartz worktops, these are the questions worth asking:
-
Who fabricates your worktops? A reputable company should be able to name their fabricator and speak to their compliance standards.
-
Do they use wet cutting and water suppression throughout the fabrication process?
-
Are their on-site installation teams HSE-trained?
-
Is any on-site adjustment work done outdoors, with appropriate PPE?
If a company can't or won't answer these questions clearly, that's telling you something.
Are There Alternatives to High-Silica Quartz?
Yes - and this is an area the industry is actively moving on. Australia has already banned engineered stone with a silica content above 40%, and the UK is under pressure to consider a similar approach. Some UK suppliers have already stopped offering high-silica quartz voluntarily, moving toward lower-silica alternatives or different materials altogether.
For homeowners, the practical alternatives to standard engineered quartz include:
-
Low-silica quartz (some brands now offer products with 40% silica or below)
-
Porcelain - extremely hard, non-porous, and entirely silica-free in the finished surface
-
Granite - a natural stone with lower silica content than engineered quartz
-
Dekton - an ultra-compact surface using a different manufacturing process
Each material has its own characteristics in terms of appearance, maintenance, and cost. The right choice depends on your kitchen, your lifestyle, and how you use the space.
How Harry Joshua Designs Approaches Worktop Safety
At Harry Joshua Designs, we work exclusively with fabricators who meet full HSE compliance standards. That means wet cutting throughout, monitored air quality, proper respiratory protection for every team member, and on-site adjustments carried out safely - always outdoors, never dry, never rushed.
We offer quartz worktops across a range of styles and price points, and we're happy to talk through the options - including lower-silica alternatives - so you can make a choice that's right for your kitchen and your values. If you've seen the recent headlines and have questions, we'd rather you asked them than worried in silence.
Bespoke kitchens are a significant investment. You deserve to know exactly what goes into yours - and exactly who is responsible for making it.
The Bottom Line
The new HSE rules on quartz worktops are a positive development for the industry. They protect workers who have, in some cases, been seriously let down by employers who prioritised cost over safety. They also create a clearer distinction between compliant, responsible businesses and those operating below standard.
For homeowners, the message is simple: your quartz worktops are safe to live with. The risk is in the fabrication, not in the finished surface. But the rules are a useful prompt to ask better questions of the companies you invite into your home - and to choose one that takes their responsibilities seriously at every stage.
