Why Electrical Labelling Matters

Under the UK’s Wiring Regs and IET Guidance Notes, clear and durable labels are required for:

  • Consumer units
  • Distribution boards
  • Meter tails
  • EV charge points
  • Solar PV installs
  • Any circuit that poses risk or isn’t obvious

Here’s what proper labelling does for you:

  • Keeps installations organised and easy to inspect
  • Prevents accidental disconnection or overload
  • Supports fault-finding and maintenance
  • Helps you meet legal requirements (e.g. BS 7671 wiring regs)
  • Reduces callbacks and confusion for future sparkies

Must-Have Electrical Labels

Here are the most common electrical labels every sparkie should have in their van or tool bag:

Danger 230 Volts / High Voltage Labels

  • These are legally required to warn about potentially dangerous live circuits.
  • Stick them on fuse boxes, distribution boards, switchgear, or any accessible voltage source.

Isolate Elsewhere Labels

  • For equipment connected to a remote supply point.
  • Prevents someone assuming it’s safe when it isn’t. Use on isolator panels and industrial plant gear.

PV Solar Labels

  • If you’re installing solar or hybrid systems, clear labelling is a must.
  • Labels like “Dual Supply”, “PV Supply – Do Not Remove”, and “Battery Storage Circuit” are critical for safety and compliance.

Circuit Identification Labels

  • Write-on or pre-printed labels to mark what each breaker, fuse or MCB does.
  • Helps everyone from landlords to tenants – and your future self – understand the layout quickly.

Test & Inspection Labels

  • Every install or EICR needs a “Tested by” or “Next Inspection Due” sticker.
