The Short Answer

Many standard Neolith designs contain some crystalline silica, which comes from the natural minerals used to make them. The exact amount varies by design and is set out in the manufacturer’s safety data sheets. In 2024 Neolith introduced silica free formulations, starting with Arctic White and Abu Dhabi White in 20mm, as part of a wider move towards safer surfaces.

For homeowners, the key point is that an installed worktop poses no silica risk in normal use. The health risk from crystalline silica arises when dust is created during cutting, grinding and polishing in the workshop. That is why the safety of the people who fabricate your worktop matters so much, as does the way they work.

This guide explains what silica is, why it matters, how Neolith compares with other materials and what to look for in a responsible fabricator.

What Is Crystalline Silica?

Crystalline silica is a natural mineral found in sand, stone and many building materials. Quartz is its most common form. In solid form it is harmless. The danger comes when it is cut, ground or polished, producing very fine respirable dust that can be breathed deep into the lungs. Long term exposure can cause silicosis, a serious and irreversible lung disease.

Workers who fabricate stone worktops are most at risk because their work generates this dust every day. This has led to tighter regulation and growing demand for lower silica materials across the industry.

The Regulatory Picture in the UK

Under the Control of Substances Hazardous to Health Regulations, fabricators must keep exposure to respirable crystalline silica below the workplace exposure limit of 0.1 mg/m³. In May 2026 the Health and Safety Executive announced a major focus on engineered stone, publishing updated guidance and a programme of more than 1,000 inspections of fabricators over 2026 and 2027.

HSE guidance highlights that engineered stone can contain up to 95% crystalline silica and sets out controls including lower silica materials, on tool water suppression, suitable respirators, health surveillance and thorough cleaning. Abroad, Australia banned engineered stone from July 2024 following silicosis cases among workers.

How Neolith Compares With Other Materials

Crystalline silica content varies widely between worktop materials. Traditional engineered quartz is typically around 90% or more crystalline silica. Low and zero silica engineered surfaces are now available. Sintered stone and porcelain contain silica bearing minerals in many designs, while some newer formulations, including Neolith’s silica free range, remove crystalline silica altogether.

Is Neolith Safe for My Home?

Yes. Once a worktop is installed, it does not release silica dust during everyday use such as cooking, cleaning or cutting food on a chopping board. The documented health risk relates to the dust created during fabrication. Homeowners are not exposed to that risk in normal kitchen use.

The main thing to avoid is any cutting or grinding of stone inside your home. Reputable fabricators carry out all cutting in their workshop with proper controls. Industry guidance warns that any fabricator offering to cut slabs dry on your driveway or in your kitchen is one to avoid.

Neolith’s Move to Silica Free Surfaces

Neolith announced its silica free formulations in 2024, describing them as devoid of crystalline silica. The first colours were Arctic White and Abu Dhabi White in 20mm, with the range expected to grow. This sits alongside the company’s wider sustainability commitments, including renewable electricity, recycled process water and high levels of waste reuse.

If silica content is a priority for you, ask your supplier which Neolith designs are available in silica free formulations and request the relevant product information. Availability can change as ranges develop, so it is worth checking at the time you order.

Questions to Ask Your Fabricator

A responsible fabricator will be happy to answer questions about how they protect their team. Ask whether they cut wet, whether they use extraction, whether cutting is done in the workshop and how they manage health surveillance. Ask which products they offer in low or zero silica formulations. Clear, confident answers are a good sign.

At Precious Marble our team fabricates every worktop in our own workshop in Elstow. Keeping fabrication in house means we control how each slab is cut and finished, rather than relying on subcontractors.

Common Misconceptions About Silica

One common misconception is that a worktop containing silica is dangerous to live with. As the guidance above makes clear, the risk arises from breathing fine dust created during fabrication. A solid, installed surface does not release that dust during cooking, cleaning or everyday use.

Another misconception is that all stone worktops carry the same level of risk. Silica content varies widely, from very high levels in traditional engineered quartz to zero in silica free formulations. Natural stones also vary depending on their mineral make up. Comparing specific products rather than broad categories gives a much clearer picture.

A third misconception is that choosing a silica free surface removes the need for good fabrication practice. Dust from any stone or ceramic should be controlled, so wet cutting, extraction and suitable protection remain important whatever material is being worked.

Planning Future Changes Safely

If you ever need to alter your worktop after installation, for example to fit a new hob or sink, always use a professional who can control dust properly. Where possible, sections should be removed and adjusted in a workshop rather than cut in the kitchen. Keeping a record of your Neolith design name and thickness helps any future fabricator plan the work safely.
