Below what height must we have toughened windows on the first and second floor of a house because I have seen and heard different heights depending where I look. Is it below 900mm or 800mm and is that the glass or the wooden ledge?
Toughened windows below what height?

800mm.
Unless you have a wooden ledge which can break into dangerous shards when you throw a brick at it (unlikely!) then it's the glazed area only.

Sorry, I was being smart with my comment.
Think about it though. You are protecting you and your family against shards of razor sharp material (i.e. glass).
As wood/PVCu frames don't fall into the above category you only need to consider the glazed area.

Ok. My concern is that some of my existing window openings are at 760mm ie the glass within the UPVC frame starts at 760mm height but the frame is a little lower. If we now replace those windows these will definitely have to be toughened right?
If yes then can only part of that glass be toughened (assuming you can toughen some part of the glass and not the rest?

There is no requirement for toughened glass.
The requirement is that glass within a critical location - in this case within 800mm from a floor or platform, should be in either small panes, be protected from impact, or if it breaks to break safely.
And no, you can't just have part of a pane toughened

There is also a requirement that glazing within close proximity (300mm) to protected areas be made the same.

There are other ways to protect the glazed area but toughened glass is usually the simplest solution. Out of interest, if it was possible to toughen only part of a glazed pane - which it isn't - why would you want to do that anyway?
Some glazing firms have indicated that only the inside pane is toughened and the external pane is not.
Also if you have panelled glass with a break in material, I guess it's only the lower sections and not the upper ones which are in their own pane that don't require toughening.
It's both panes of a DG unit, as the requirement relates to any glass pane within the critical zone.
Likewise, yes a glazing bar will break up the zone, so only glass within the critical zone needs to meet the requirement.

A patio door should really be quoted for safety glass as standard, as normal glass is not an option. If you ask for normal glass they can't even sell it to you as they would contravene a consumer supply regulation - the name of which escapes me.
The requirement is for safety glass, which could be toughened or laminated. There might be a cost difference between these two, so yes one or the other would be an option.

Given that we have small children is it worth considering laminating the large opening from the outside with laminate glass from both a security perspective but also the realistic assumption that kids will kick balls about or hit them with bars and a laminate glass will take Knocks than regular glass?
