Is staggering a levels discouraged if you have extenuating circumstances

Hi, due to a life threatening illness which resulted in me missing over half of year 12, I decided to do a level maths with my current year but doing further maths and economics with the year below. Would this be considered disadvantageous even if i got an A* because I am fairly confident I can do so and dont see any point in me moving down a year for maths aswell.
I acheived majority 9s at gcses (7 and 4 8s) and am looking to apply to univerisities like LSE, imperial and UCL for economics or finance.

Why not just do all three of your A-levels the following year, then you avoid the problem, and ensure you have plenty of time to be confident in the content?

I got a 9 in further maths gcse last year so im confident i can get an a* i really dont want to drop down in maths aswell as i feel it would be a waste of time. Do you think univeristies like ucl or lse will view this unfavourably considering my circumstances ( if i didnt get ill i would have done 3 in one sitting ) which were life threatening

Honestly it's probably easiest just to contact the unis and ask them directly. As then you have concrete information from the source to go on @DerDracolog's point about any strictness in admissions in terms of mitigating circumstances in this case probably does reflect (negatively) on their adminstration of their degree programmes is a very salient point to consider as well...!

I emailed lse and they just copied what it says on their website lol
"We would highly recommend that your teacher's reference notes all relevant details about your educational history (past, current, and future performance) so that we can take into account circumstances that have affected your academic journey. On our Admissions Information webpage, we do mention a preference for students who have achieved high grades in their first attempt (and in one sitting) at relevant examinations. However, this guidance further notes the importance of ensuring that LSE is aware of extenuating circumstances that may impact an application, for example caring responsibilities, serious, acute or chronic illness, or significant adverse personal circumstances (with student consent). We're looking for students with the very best academic achievement, potential and motivation, and we use the UCAS reference to find out about the academic ability and interests of the student applying, their understanding of their chosen discipline and suitability for university level study, within their personal and social context."

What is your opinion on how they'd view it (no hard feelings of course).

I dont know how to interpret it as in does it put me at a disadvantage because i feel what they said is basically sitting on the fence about it saying we could go either way. What do you think (sorry if im going round in circles just want some clarity)

You're right to be honest. Its mainly the fact that all other unis bar lse and ucl have given me positive responses saying there wouldnt be an impact yet I am very keen on going to those 2 unis .Is it possible to dm or email you a follow up more personal question its not allowing me to dm
