Stone-worktop due diligence is moving further up the kitchen supply chain

What happened

In a statement reported on 17 July, the WFF said the industry’s focus should move from discussion to action. It encouraged fabricators, suppliers, retailers and kitchen studios to take a role in raising standards and said it was introducing an accreditation quality mark as part of that work.

The WFF has said participating businesses in its quality-mark scheme will be subject to workplace assessments and other requirements. The scheme is an industry accreditation rather than a statutory approval, and its presence should not be treated as a substitute for the legal duties that apply to the business carrying out the work.

The development follows HSE guidance and an inspection programme covering more than 1,000 fabricator visits. HSE says its guidance effectively rules out dry cutting, grinding and polishing unless a business can demonstrate an equally effective or better control. HSE also makes clear that this is not a new law or formal legislative prohibition.

Why it matters for UK kitchen projects

A homeowner may choose a worktop in a kitchen showroom using a brand name and sample. The slab could then be supplied through a distributor, fabricated by a separate workshop and installed by another team.

The showroom name or worktop brand does not necessarily identify the employer responsible for controlling fabrication dust. It may also be unclear from an early quotation whether templating, cutting, delivery and fitting are being provided by one company or several.

That distinction becomes particularly important when a design changes after templating. A revised sink, hob, tap or socket position can alter a cut-out or edge detail. The change should return through the responsible supplier and fabricator so its effect on material, process, timing and cost can be confirmed.

Homeowners are not responsible for designing workplace controls. They can, however, avoid creating project records that obscure who is responsible or encourage unplanned alterations in the home.

What homeowners may need to revisit

Ask the kitchen retailer or worktop supplier to identify the business responsible for fabrication and the business responsible for installation. Keep their names beside the worktop quotation rather than recording only the surface brand.

Save the exact material name, colour or design reference, thickness, edge profile and any available composition or technical documentation. A general description such as “quartz” or “stone” may not be enough to identify the ordered product later.

Keep the approved template and the final details for sinks, hobs, taps, drainer grooves and other cut-outs. Confirm who must approve a change after templating and whether it would require a new template, workshop alteration or revised installation date.

Where a supplier refers to an accreditation or quality mark, record the scheme name, the accredited business and the date on which the status was checked. Do not assume that a mark attached to one business automatically covers every subcontractor or every stage of the project.

Do not request improvised dry cutting or grinding in the home. Any alteration should be referred back to the supplier, fabricator and competent professionals responsible for the work.
