# UKCA mark

**UKCA mark: The manufacturer declares the product meets Great Britain's rules — the British counterpart to CE.**

## What it looks like

The letters UKCA in a plain sans-serif block.

## What it means

Introduced on 1 January 2021 for Great Britain, with Northern Ireland continuing to use CE or the UKNI mark. The transition deadline was extended repeatedly, and in 2023 the government said CE marking would continue to be recognised for most goods indefinitely, so products in British shops carry CE, UKCA or both. It is a self-declaration on the same model as CE, and the two marks may appear side by side without either being redundant.

> Defined by UK Product Safety and Metrology regulations. Where a symbol differs between standards, the difference is described above rather than resolved — both versions are in circulation on real labels.

| FCC mark | The device meets US limits on radio-frequency interference. |
| RoHS compliant | The product restricts ten hazardous substances, including lead, mercury, cadmium and four phthalates. |
| Crossed-out wheelie bin (WEEE) | Do not put this in household waste — take it to a separate collection for electrical items or batteries. |
| Crossed-out bin with Pb, Cd or Hg | A battery for separate collection which also contains lead, cadmium or mercury above the reporting threshold. |

| IP rating (IP67, IPX4) | How well the enclosure keeps out solids and water. First digit solids 0–6, second digit water 0–9. |
| EU energy label (A to G) | How efficient the appliance is, on a scale from A to G, alongside consumption figures. |
| EnergyGuide label (US) | The estimated annual energy cost of this appliance in the US, and how it compares with the range for its class. |
| Alternating current (AC) | Alternating current. On a power supply it marks the mains input side. |
