If you have ever browsed kitchen or bathroom taps online, you may have noticed the letters “WRAS” appearing on product listings or packaging. For some buyers, it is easy to scroll past this detail without giving it a second thought. But if you are investing in a new tap for your home or commercial property, understanding WRAS approval could save you from a costly and potentially unsafe mistake. In this guide, we explain what WRAS certification means, what risks come with uncertified products, and how to verify compliance before you buy.
What Is WRAS?
WRAS stands for the Water Regulations Advisory Scheme. It is an independent, UK-based organisation that tests and certifies water fittings, materials, and products to ensure they comply with the Water Supply (Water Fittings) Regulations 1999. These regulations exist to protect the public water supply from contamination, waste, and misuse.
In practical terms, WRAS approval means that a product has been independently assessed and confirmed to be safe for use with drinking water in the United Kingdom. This covers a wide range of items, from pipes and valves to taps, showers, and boiling water appliances.
Why Does WRAS Certification Matter?
The UK has some of the highest drinking water standards in the world, and the Water Fittings Regulations are a cornerstone of maintaining those standards. When a product carries WRAS approval, it has passed rigorous testing to confirm that:
-
It does not contaminate drinking water with harmful substances, including lead, nickel, or other chemicals that could leach from materials in contact with water.
-
It does not encourage the growth of bacteria, such as Legionella, within the fitting.
-
It performs reliably over time without causing undue waste of water.
-
It meets the structural and performance standards required for consistent, safe water flow.
Without this certification, there is no independent guarantee that a tap or fitting meets any of these criteria. The product may look identical to a certified one, but what you cannot see are the internal components, seals, and materials that actually come into contact with your drinking water.
The Hidden Risks of Uncertified Taps
The market for kitchen and bathroom taps is vast, and a significant portion of the products available online have been manufactured to a price point rather than a quality standard. This does not mean that every uncertified tap is dangerous, but it does mean that you are taking a risk you have no reliable way of assessing.
Legal Liability
In the UK, it is the responsibility of the installer and the property owner to ensure that all water fittings comply with the Water Fittings Regulations. Installing a non-compliant tap is not simply a technical oversight; it is a breach of regulation. Water companies have the authority to inspect properties and, if non-compliant fittings are found, the property owner can be required to replace them at their own expense. In commercial properties, the consequences can be even more serious.
Insurance Implications
If a water leak or contamination incident occurs and it is traced back to a non-compliant fitting, you may find that your home insurance does not cover the damage. Policies typically require that all fittings and appliances are installed in accordance with applicable regulations. Using an uncertified tap could therefore invalidate your claim at precisely the moment you need it most.
Health Concerns
Taps made from inferior alloys or with substandard internal components can leach metals into your drinking water over time. This is a particular concern with boiling water taps, where high temperatures can accelerate the leaching process. WRAS testing specifically addresses this risk, ensuring that certified products are safe across the full range of operational temperatures.
How to Verify WRAS Compliance Before You Buy
Fortunately, verifying whether a product is WRAS-approved is straightforward. Here is what to look for:
-
Check the WRAS Product Approval Register. WRAS maintains a publicly accessible online database of all approved products. You can search by manufacturer, product name, or approval number. If a product claims WRAS approval, you should be able to find it here.
-
Look for the approval number. Genuine WRAS-approved products carry a unique approval reference number. Ask the supplier for this number and cross-reference it on the WRAS database.
-
Be cautious of vague claims. Descriptions such as “WRAS-compliant” or “WRAS-standard” are not the same as WRAS-approved. Only products that have undergone independent testing and received a WRAS approval number are genuinely certified.
-
Ask your supplier directly. A reputable supplier will be able to provide documentation and approval numbers without hesitation. If a supplier is evasive or cannot produce evidence of certification, treat that as a significant warning sign.
WRAS and Boiling Water Taps: An Extra Layer of Scrutiny
Boiling water taps present additional considerations beyond those of a standard kitchen or bathroom tap. Because they deliver water at or near 100°C, the materials used in their construction are subject to greater thermal stress, and the risk of chemical leaching is correspondingly higher. WRAS testing for boiling water taps takes these factors into account, making certification particularly important for this category of product.
At UK Brassware, our boiling water taps carry full WRAS approval, alongside RoHS certification for electrical compliance. This means that every product in our range has been independently verified to be safe, durable, and fit for purpose in a UK domestic or commercial setting.
The Bottom Line
WRAS approval is not a marketing badge or a nice-to-have feature. It is a meaningful indicator that a product has been independently tested to meet the water safety regulations that govern every property in the United Kingdom. Choosing a WRAS-approved tap protects your household’s health, safeguards your legal compliance, and gives you confidence that the product will perform reliably for years to come.
When evaluating taps, always ask for the WRAS approval number, check it against the public register, and be wary of any product or supplier that cannot provide clear evidence of certification. It is a small step that makes a significant difference.
