Santa, sledge and reindeer are all over the place this year - flying over roofs, climbing up walls: you name it.
Lots of these look to be pretty firmly fixed 'garden' electrical installations.
So will they be legal next year? That is, without a building notice or installation by a paid up part P sparky.
Ok, so most are on a 13A plug, but does that affect the issue? My reading of Part P is that it is the nature of the installation (ie whether it is fixed/screwed/bolted/nailed/clamped/glued to the building or garden grounds) that matters, not its manner of connection to the elec supply.
