Yes Freddie, BUT, I mentioned further in that sentence it only applies to the Bathroom areas (Ensuites, Bathrooms, Half-Bathrooms, WHATEVER you wish to call it)...
PERHAPS further when children are involved.
I'll not mince words here, if it were AT ALL feasible to temper only the supply to the bathroom, we probably would've. But the tight space where the plumbing splits between the Kitchen/Laundry and Bathrooms is too tight, and the risk of flooding, damage if something bad happens too great.
Keep it on the roof, temper the whole house. Yes, I object, but I live with it quite happily. We don't have any TL or FL machines that require very hot inlet anyhow, so no harm hey?
BESIDES - Modern machines throw error codes if you give them water thats too hot for their liking...
As for Kids or the Elderly, lapses in attention happen. Those who might not be in full possession of their faculties might not react the way other people might when presented with this situation, and instead choose to freeze or do something else out of the ordinary, hurting themselves even more.
Parents/Carers might loose concentration for that moment, and the damage is done. No, you can't fix stupid, but even good parents will slip up on occasion.
In most instances, better to be safe than sorry.
Here's my "rant" from last year too - Note for member Rapunzel, you can see the Government literature attached by Ronhic at the end of the thread.

That post should give you all the background on my "opinions" on this... Lest I post it again!
I too will bow down now - I think this might be getting towards a personal level, and I'd hate to see that happen.
