Im - How are things today?
Great advice from the fantastic Why - she's spot on. Write that line down on a piece of paper, in VERY BIG LETTERS.
Put it somewhere that you can read it when you need to, inside a shoe or somewhere he won't go. Then every time that you wobble, READ IT!
When is your next meeting? Have they said? I hope your solicitor gets things moving fast for you so that you and the DC are as safe as they can be.
Is the Non Molestation Order in place yet?
When you said this -
I feel like I'm trapped because as soon as SS confirm how bad it is they will take my dc this has been like this as they know it sinse 2011
I have to tread carefully we have another meeting soon.
One good thing is they say my dc are well cared for in every other way but are at harm emotionally
They know my dd is guarded shes hiding what she knows x
That is so sad! Bless her heart 
Is your DD scared of going into care or of something else? Is she scared DH/P will hurt you if she says anything?
It's all such a mess of emotions and not knowing what to do.
You need to be honest though, as tough as that will be, to protect your children, to protect yourself, this has all got to stop.
2011 is a long time. What has been going on since then?
Are the DCs on the Child Protection Register now? They need to be, he has to be shown for what he is and you have to get out of there.
You can't change the locks as Why has said if the house is in his name or jointly owned (look at that link I sent you up thread about the Survival Guide from WA, the part about An Occupation Order) because he has as much right to be there as you if it's jointly owned/rented and you've BOTH been paying the bills, also, if it's HIS house, you have NO LEGAL RIGHTS to shut him out.
I know that's utterly shit. 
What do you plan to do next? Stay in the house with him or go?
Remember, he may well start being super nice to you, to try and look like the victim, the good guy, the better person..... BE CAREFUL.
Don't let your guard down, not for a second. You must be exhausted.
Did you get in contact with Shelter at all or speak to your solicitor about living away from him?
Sorry for the questions, I'm just trying to help you and to understand what's going on if this has been in the hands of SS since 2011....
I hope you are safe today.
