the dreaded UC and carers allowance

Hi, I recently reported a change of circumstance with informing the DWP that my partner was moving in with me and unfortunately we have been whipped onto universal credit, my previous benefit was Income support. I am a full time carer to my disabled daughter, who is receiving high rate care & mobility DLA, can you please tell if this will affect my carers allowance?

Also I myself am in receipt of standard rate care and low rate mobility PIP and I was receiving the severe disability premium attached to my income support, will this now stop as my partner has moved in? And also would he then be able to apply for carers allowance to care for me, or is there another care type premium he could apply for? Sorry just to add my partner is currently signed off sick from work and he is claiming ESA, and he himself is on the high rate mobility PIP.

Any information would be greatly appreciated, very confused and rather scared of this UC situation aaahhh,

Thanks

Thank you so much for all your information, ill take your advice and speak to the welfare rights, yeah that's my problem I always jump the gun in a panic and heavily regret later lol we are or the UC now aaahhh but that's really helpful the bit about missed SDP payments,

Thanks & hope you have a lovely xmas
