Haphazard lighting layout.

[ban-all-sheds]

What about the laminate flooring which the customer lays six months later over the top of the small section of floorboard you've purposely screwed back in place along with the black permanent text noting there's a junction box underneath for lighting?

Then they have changed something and made it inaccessible - not your fault any more than any future act outside your control is your fault.

I know what you mean but in the instance i described i feel i can take a little responsibility of future actions turning what could, at the time of install, be an accessibe connection into an inaccessible connection. A well fitted carpet and bedroom furniture could make accessibility difficult.
Even a connection in a concrete floor is accessible......with a kango!
