zzzz yes to the professional thing and how it's changed things massively for us once they realize what they're dealing with.
We don't live in the UK, and you can do an early self referral here for services.When we did it initially, our service coordinator was a condescending piece of shit, and had clearly been allocated to us as an english as a second language family, based solely on our foreign sounding name.
She was shocked when I met her and it clicked that we didn't speak the assumed first language after all - I'm positive that this major assumption that you only speak X at home is their default as to why kids have speech and understanding issues in the district.
I took her to task many times about being shit, unorganized and pushing for services for DS many many times as they did less than fuck all and are getting paid from the state for it. I was actually told "well; clearly, you're a lot more sophisticated and educated than a lot of the families we see, and can advocate and have no issues with the language, so you'll have no issues getting the services you need and have been assigned" 
I mean, that's great for us, but what about every other poor fecker who can't / doesn't know how to / there's a language barrier?!
The other thing that I have noticed is that even tho special education services here are dominated by women from coordinators to therapists, to the review boards, if I take DH with me, we get a special level of deference and agreement to what we're pushing for that I don't get when I'm dealing with them by myself.
Ironic really as DH is about 5% involved in any of the day to day stuff - I do find there's still a tendency to label / insinuate women parents as hysterical / overbearing
