Do these sound like asd behaviours (girl)?

Aversion to sudden loud noises - panicky, tearful, hands over ears reaction. Risk averse (mainly due to noise?) - Doesn’t like things other same age kids enjoy - cinema, bowling alley, fairground. Can’t sleep at sleepovers, prefers quiet bedtime.
Nail biting/fingers in mouth a lot of the time.
Takes a while to warm up socially even with family/friends - initially shy / avoids eye contact, hides behind parents.
Worries about getting told off at school but is perfect student.
Competitive nature, hard on own self.

In contrast..
Early talker/walker/reader, generally works at greater depth at school, excels with writing and English.

Sleeps well.
Fairly adventurous eater.
Generally fine with routine changes.
Makes and keeps friends, understands social cues, jokes, sarcasm etc. Similar interests to friends of same age.
Good co-ordination with variety of sports etc.

Happy to pay privately for help with this, but not sure which HCP would be best for this?

I think it sounds more like ASD.

How would we pursue an ASD diagnosis? GP and school have no concerns.

Go through this and tick off what is relevant.

My Dd collected Jelly cats. Never thought anything, but that was her obsession. Look at the female criteria.

My Dd was not quirky or scientific or mathematical or any of the boy things. No patterns or savant stuff. Had friends, play dates and the rest.

Thanks. Have gone through and ticked off:

Friendship: 1/3
School: 2/18
Anixety: 1/6
Emotional: 1/8
Sensory: 1/4
Social: 1/15
Austistic inertia: 1/6
Other possibilities: 4/11

I think if you look online at private autism assessments you might find some in your area. I think you can usually self refer. They are quite expensive though.
Be aware that the assessments tend to be more geared towards the male presentation of autism and girls who mask often pass regardless. If she's presenting normally at school then it's quite possible she will fly through an autism assessment, which doesn't assess things like sensitivity to noise. So it could be money wasted.
My Dc were referred for assessment through their school which tends to be the typical route if they're school age.

She has collected Jellycats before, and other similar items that are popular at the time . But so have her friends and others in her school year so I wouldn’t say it’s specific to her.

Just to update on this, we booked a private pre assessment with both an occupational therapist (specialising in sensory processing/integration) and an autism specialist. Quite a long appointment, they have come back to say there is no evidence to support looking at diagnosis for ASD or sensory processing. They feel she has over responsivity to (certain) noise, but it is likely more an anxiety issue.

If it’s helpful for anyone else in a similar situation, they said they were able to identify demonstration of a good level of social skills and ability to pick up on a number of social cues and nuances during the assessment . There was no evidence of any restricted or repetitive patterns or behaviour or interests/activities which would need to be evident and pervasive for a diagnosis. With sensory processing they they said for the vast majority of individuals with sensory processing difficulties they would present as having more than one area of sensory sensitivity or dysfunction, which was not evident in our case

That's really interesting. I'm glad you got the answer. Did they offer any advice to help?
