Structural integrity of bath supports/flooring in rented property uk

[eoep95]

Living in a renter first floor flat. Our downstairs neighbours reported a couple of weeks ago that there was a leak from our bathroom into their ceiling.
Plumber came and sorted the pipes out and the problem stopped.
We notified whilst this work was going on that there are large holes in the flooring underneath our bath. Slightly concerning but we didn’t think anything of it.
However, in the last week, I’ve noticed that whenever I get into the bath (I shower over bath) that the bath is creaking. Already slightly concerned about the large gaps in the flooring I removed the boarding again to look underneath the bath.
I noticed that one of the support looks like it’s at an angle, having no building experience I have no idea if this is something we should be concerned about. We live in a rented flat in London with our landlords in Australia and they manage the property and it’s difficult to get in touch with them.

Please let me know if it’s worth us talking about all of the above to our landlords and I’m slightly concerned about any of the flooring being rotten/the large holes in the floor and one of the supports being at an angle and not flat!

Can you take a picture a bit further back?

It wouldn't do any harm to add an extra wooden brace or two. Simply some CLS timber screwed together to make a goal post and then tap some wedges under the legs of the post until its tight on to the bath. Cost less £10.

It looks like the steel bath support is designed to sit off-vertical; its foot is flat to the support board. Agree as above, extra timber below would be an improvement, and if it stops the bath from creaking/moving when you step into it then there'll be reduced risk of further leaking from the bath-to-wall seal as you shower.
