I always install my consumer units between 450 and 1200, sometimes at 1400..
Am I right in thinking that CUs come under part M?

Extensions and rewires not covered by part M?

Anybody still installing them up at ceiling height?

On refurbs I normally get the customer to decide ......... but certainly not at Part M heights ............ they are simply daft
 
new installation, you and the client have choices. on a replacement CU, you need to fit it wherever you can considering the existing supply and final circuits.
 
Is it even in part M because I can’t see it?
It’s mentioned in part P as a guidance for the height of a CU but I don’t believe it’s actually a building regulation unless someone can show me different?
We are required tho on new builds to mount the CU with the mcbs at between 1350-1450 FFL.

I believe the idea with not installing lower than 1350mm is to prevent small inquisitive children from getting access to it and playing with the switches. I’ve read that somewhere.

I think the 1350 is a good height if it can be achieved easily enough.

Very high consumer units are not ideal. Earlier this year I had a concerned daughter call me because her rather petite and elderly mother was climbing stepladders to keep resetting a breaker for a faulty water heater. Not good.
 
Height of consumer units 3C34AFA2-3A77-4154-B632-270E9F6487FA - EletriciansForums.net I’ve spoke to my LABC officer regarding this on refurbs/rewires and his stance is that when rewiring you should not install accessories at a height that is worse than compliance, than it was before you started. For example say the existing sockets are mounted at 300 then you install them at a height off between 300 and 1200. So you wouldn’t then go and install them at 250 as then they would be installed at a height that is worse than compliance, than before you started.
 
Thanks for the responses.,
Had a few occasions lately where the builder grumbled at the height of 1400.
Another new build cu went up high at ceiling height, fortunately building inspector didn’t pick up on it, I thought it was best not to ask him about it.
I think the 45o height would be handy as it can be located in a cupboard
 
Usually see them at ceiling height over here. Was in 2 today, one built in 2014, one in 2016...both at ceiling height. On large developments as well...

Similar situation over here;
Large development, CUs in hallway above lounge door, looks naf but was probably the best location to facilitate a 2 day 1st fix.

There is a whole new build estate here with them all at ceiling height in the garage.
Another estate a few years ago they are above the basin in the hall toilet.
