Was at a job for a different reason, but saw this and was curious.
Asked the tenant, and they didn't know what it was for either.

Any ideas? Its obviously come from a Hager DB sticker pack.

I'm guessing as its a 6A, smoke alarm?

Smoke alarm would be my guess, but then I found this image:

Which has a different symbol far left which I'd guess is smoke alarm, or maybe heat alarm?

Given the standards on everything else, you'd think they'd have come up with a standard for symbols to be used on CU by now (At £150 per copy, naturally)
 
What the heck is Circuit 3 ? Dustbin power ?
No idea - waste disposal maybe, but who runs that separately? Pop up sockets? seems a bit too niche to have a symbol....

Or maybe it's meant to be an immersion tank? That at least would make sense on a 16A, but not a great image...
 
Central vacuum cleaner? The ones that have a ducted outlet in the walls you plug hoses into.... or could simply be a hot water tank??

why don’t they use the printed stickers with words instead.... then you get to know which upstairs lights, downstairs light etc.... not just “lights”
 
Most electricians writing is worse than a doctor, never seen a legible written one yet. Tin hat on.
i have to admit to neat writing. my lad on the other hand.... his looks like it's done by a drunken spider with parkinsons.
