I was born in uk I am moving back to uk next year. I was getting DLA when i got the age to get. So my question is that when i get back to the uk will still get the DLA.

Maybe, maybe not. If you have claimed before you should know it is not based on diagnosis. Its based on what care and mobility needs you have due to the disability that others without a disability do not have.
Someone who is wheelchair bound may get nothing because they have a million adaptations to assist them so they do not need care. Someone who has an unseen disability and appears to others to have no disability may have 101 care needs.

But that aside DLA is being done away with shortly and is being replaced with Personal Independence Payments (PIP). From what I have read it will much harder to claim.

Thanks for the information

with this in mind I wouldn't come back relying on supplementary benefits! At long last some are becoming very difficult to justify

Especially as that ended in 1988.

Not being rude...just couldn't resist.

thanks, just looked it up on Wiki- there was as you say something specifically called "supplementary benefit".....looks like what is now called Income Support......but obv what I meant OP was just don't rely on getting anything as it's all been overhauled & more difficult to obtain !

And more to come.

If you are coming back and then claiming beneit there is a bureaecratic hurdle. THE HABITUAL RESIDENCY TEST.

Note that Income Support is about to become "Universal Credit" which is neither universal nor credit.
