Product Safety

Counterfeit electrical products: what to check before you plug them in

Counterfeit and unsafe electrical products can look convincing online, but poor components, missing protection and false safety markings can create serious fire and electric shock risks.

Safety guidance

This TESC guidance page is designed to help households, landlords, agents and property managers recognise avoidable electrical risks before they become incidents.

Product safety is separate from an Electrical Installation Condition Report. An EICR assesses the fixed electrical installation, while plug-in equipment, chargers, extension leads and portable products can introduce additional risks after the installation itself has been inspected.

What to look for

Key issues, warning signs and safer practice.

Why counterfeit electrical products are dangerous

  • They may use undersized cables, poor insulation or weak internal connections.
  • They may overheat under normal use because the product has not been properly designed or tested.
  • They may display fake or misleading CE, UKCA or approval marks.
  • They may not include effective fuses, thermal cut-outs, strain relief or short-circuit protection.

Common products to treat with caution

  • Phone chargers and USB power supplies.
  • Extension leads, adaptors and multiway sockets.
  • Hair dryers, straighteners and heated beauty products.
  • E-bike, scooter, power bank and lithium battery chargers.
  • Low-cost imported lighting, lamps and plug-in devices.

Before buying online

  • Check whether the seller is a recognisable UK retailer or an unknown marketplace listing.
  • Be cautious where the price is far below normal retail value.
  • Look for proper UK plug design, instructions, manufacturer details and warranty information.
  • Avoid electrical products with poor images, vague descriptions or copied brand names.
  • Do not assume a product is safe just because it appears on a large marketplace.

When electrical products should be taken out of use

Stop using an electrical product if it shows signs of overheating, melting, burning smells, loose connections, damaged cables, exposed parts, buzzing, cracking, smoke or repeated tripping. Do not keep testing a suspect product to see whether it happens again.

Where the concern relates to fixed wiring, sockets, consumer units, earthing, RCD protection or repeated circuit faults, the matter should be checked by a competent electrical contractor rather than treated as only a product issue.

Common questions

No. Many unsafe products look convincing externally. The risk is often inside the product: weak components, poor insulation, missing fusing or low-quality connections.

Stop using it immediately, unplug it if safe to do so, and do not continue testing it. Heat, burning smells, buzzing or melting are warning signs.

An EICR assesses the fixed electrical installation, not every portable appliance. However, unsafe plug-in products can still create fire or shock risks in the property.

Electrical safety records matter

Product safety, fixed wiring safety and compliance records all work together. Use TESC resources to understand electrical risks, check EICR records and find registered providers where inspection or remedial work is needed.
