Find Out Why Metal Switches Are Safe and Reliable for Your Home or Business

If you've been browsing our range of decorative wiring accessories, you've probably asked yourself: are metal switches actually safe to use in a home or commercial property? It's a fair and sensible question. After all, metal conducts electricity, so why would you want a metal faceplate on your light switch or socket? The short answer is: yes, metal switches are absolutely safe. But the longer answer is worth understanding, especially if you're an electrician, a specifier, or a homeowner who wants to make an informed decision.

In this guide, we'll walk you through how metal switches are designed and tested, what safety standards they meet, where they should and shouldn't be used, and why they remain one of the most popular choices for modern interiors.

How Are Metal Switches Made Safe?

The key to the safety of metal switches lies in the way they're engineered. While the outer faceplate is indeed made from metal, typically brushed steel, polished chrome, antique brass, black nickel, or matt black, the internal components are carefully isolated from it.

Here's how that works in practice:

•        Insulated internal mechanisms: The switch rocker, terminal connections, and live parts are all housed in a non-conductive plastic body behind the metal plate. The metal faceplate itself carries no electrical current under normal operating conditions.

•        Earthing: Metal faceplates are required to be earthed in accordance with BS 7671 (the IET Wiring Regulations). An earth connection is made via a dedicated earth terminal on the mounting box or the switch plate itself, meaning any stray current is safely directed away rather than remaining on the surface.

•        Tested to British Standards: All quality metal switches sold in the UK must comply with BS EN 60669-1 for switches and BS 1363 for sockets. Products from brands such as BG Electrical, Knightsbridge, Click Scolmore, and Hager, all available here at West Base, are rigorously tested to meet these standards before reaching the market.

What Does Earthing Mean for a Metal Switch?

Earthing is a fundamental safety concept in UK electrical installations. For metal switches and sockets, earthing ensures that if a fault were to cause the metal plate to become live, for instance, due to a wiring error or insulation failure, the current would immediately flow to earth rather than through the person touching it.

This is why it's essential that metal switches are always installed by a competent electrician who correctly terminates the earth conductor at the earth terminal on the mounting box. If you're replacing an existing plastic switch with a metal one, it is a requirement under Part P of the Building Regulations that the installation is either carried out by a registered competent person or notified to your local authority building control.

Are Metal Switches Safe in Bathrooms?

This is where things get more nuanced. Bathrooms are classified as 'special locations' under BS 7671 due to the presence of water, and there are strict zone requirements that govern which types of electrical accessories can be installed where.

Standard metal switches and sockets, whether plastic or metal, are not suitable for use inside zones 1 and 2 of a bathroom (directly over or within reach of a bath or shower). However, metal accessories can be used outside these zones, provided they are correctly earthed and the installation complies with current regulations.

For bathroom light switches, many homeowners and designers opt for a ceiling-mounted pull cord switch, which keeps the control point well away from any water source. Alternatively, a standard metal plate switch can be installed outside the bathroom door or in the hallway, which is completely safe.

Always consult a qualified electrician if you're unsure about bathroom installations.

Are Metal Switches Safe in Kitchens?

Yes, metal switches and sockets are commonly used in kitchens and can look particularly striking in modern or industrial-style designs. However, there is one important consideration: sockets should not be installed directly above a sink or in a position where they could be splashed with water.

As a general rule, sockets in kitchens should be positioned at least 300mm horizontally from the edge of a sink. Switches controlling fixed appliances such as dishwashers or washing machines should likewise be placed out of reach of water. These rules apply equally to both plastic and metal accessories.

Do Metal Switches Feel Safe to Touch?

One of the most common concerns people have is whether a metal switch will feel different, or potentially unsafe, to operate compared to a plastic one. In reality, a properly installed and earthed metal switch feels no different to use. You won't experience any tingling or shock during normal operation.

Some people notice that metal switches feel slightly cooler to the touch than plastic ones, particularly in older properties. This is simply a result of metal's thermal conductivity, the surface draws heat away from your fingertip more quickly than plastic does. It's perfectly normal and not a cause for concern.

What Are the Advantages of Metal Switches Over Plastic?

Beyond safety, there are plenty of practical and aesthetic reasons why metal switches have become so popular:

•        Durability: Metal faceplates are significantly more resistant to scratches, dents, and discolouration over time compared to their plastic counterparts. Many metal switch ranges, such as the BG Nexus Metal series, come with a 25-year manufacturer's guarantee.

•        Aesthetic appeal: Metal switches are available in a wide range of finishes, brushed steel, polished chrome, black nickel, matt black, antique brass, and more, making them a popular choice for premium residential projects, hotel fit-outs, and commercial interiors.

•        Premium feel: The weight and solidity of a metal faceplate gives switches and sockets a higher-quality feel compared to standard white moulded plastic, which can make a tangible difference to the perceived quality of a room.

•        Versatility: Metal switch ranges typically offer a comprehensive selection of products, from single and double sockets to USB-integrated sockets, cooker switches, dimmer switches, and data outlets, all in a coordinated finish.

Top Tips for Installing Metal Switches Safely

Whether you're a professional electrician or a competent DIYer, here are the key points to keep in mind when fitting metal switches:

•        Always connect the earth: Never leave the earth terminal unconnected on a metal faceplate. This is a critical safety requirement.

•        Use a metal mounting box: For a neater finish and correct earthing continuity, metal accessories are generally best installed with a metal back box, with the box itself also connected to earth.

•        Turn off the power: Always isolate the circuit at the consumer unit before working on any electrical accessory. Test with a voltage detector to confirm the supply is dead before touching any wiring.

•        Use the correct tools: Metal faceplates can have sharp edges, use appropriate screwdrivers and take care when handling the plates, particularly brushed steel and chrome finishes that can mark easily.

•        Comply with Part P: If you're not a registered electrician, electrical work in domestic properties must be notified to building control. In practice, most homeowners hire a qualified electrician for switch replacements.

The Verdict: Are Metal Switches Safe?

Absolutely, when correctly installed and earthed, metal switches are just as safe as plastic ones. They meet the same British Standards, they're subject to the same wiring regulations, and they come with the same built-in electrical isolation between the live parts and the metal surface you touch.

What sets metal switches apart is that they combine that safety with a premium aesthetic that plastic simply can't match. From the weighty feel of a brushed steel rocker to the sleek elegance of a matt black double socket, metal accessories elevate the look and feel of any electrical installation.
