As I've said, I have not yet found any evidence that there IS any "Welsh law" to link to.With the English version there is a link to the actual law ...
My searches have not found any such legislation, and if such legislation actually existed, government documents such as the one about "fitness for human habitation" that Murdochcat and myself have mentioned do not link to, nor even name, any such legislation ('law'). As I've said, the only Welsh legislation it does mention (right at the start) appears to say nothing about electrical inspections (unless I'm missing it)
The 'Welsh version' of what? As we are agreed, the 'fitness for human habitation' document is not legislation/law., but the Welsh version has no link, so it is some ones opinion of what the law means, not the law.
As things stand, I'm coming progressively closer to thinking that you/we are looking for Welsh legislation ('law') which does not exist - but it would then be difficult to understand the basis of what the 'fitness for human habitation' document is going on about.
Kind Regards, John
