An LED mirror does not automatically require a separate fused spur simply because it is wall mounted. The right connection and protection depend on the mirror instructions and the circuit supplying it. A registered electrician can determine whether a fused connection unit is needed for your installation.
Choose the mirror for the size, lighting and features you want, then plan its electrical connection correctly. This is more useful than buying a particular fuse or accessory before the installation has been assessed.
What a fused spur actually does
A fused connection unit contains a fuse for the connected supply. The fuse is designed to interrupt excessive current; it is not a surge protector and does not by itself make an installation compliant. It also serves a different purpose from an RCD. Electrical Safety First explains how fuses protect against excessive current.
A switched connection unit can also provide a convenient switching point. Its location, fuse rating and suitability belong in the electrical plan, alongside the cable and circuit protection. There is no single fuse rating we can correctly assign to every LED mirror from its shape or screen size.
Three questions to settle before installation
On a small screen, swipe the table to compare all columns.
| Question | Why it matters |
|---|---|
| What connection does this mirror support? | The product instructions establish how the mirror should be supplied. |
| Which circuit will supply it? | The existing circuit and its protection affect the connection arrangement. |
| Where will the mirror and switch sit? | Bathroom location, access and cable clearance need to work together. |
A hardwired connection is not the opposite of a fused spur: a fixed mirror can be connected through a fused connection unit. Equally, the presence of a fused connection unit is not a substitute for checking the rest of the installation. Use a registered electrician for the fixed electrical work.
Plan around the complete mirror, including the demister
Lighting is only part of the electrical specification when a mirror also has a heated demister, clock or speakers. Give the installer the complete product information rather than quoting only the LED wattage. Our demister pad guide explains the heated area, and the demister installation guide covers planning a change to an existing mirror.
If you are replacing an existing two-door mirror cabinet, use the new cabinet’s specifications for the new installation. A shaver-socket feature is an outlet for compatible grooming equipment; it is not the incoming power supply for the mirror itself.

Choose your style without confusing it with the wiring
Explore backlit mirrors for a wall glow or arched mirrors for a softer outline. The in-stock 80 cm round backlit mirror is another circular option.
Already own a square dual-light mirror or round RGB mirror? Refer to that model’s instructions when discussing its connection; a different mirror’s fuse specification is not a substitute.
