Esa and holidays abroad

Would a trip to Germany to visit my sister whilst I am o ESA support group mean my claim would be stopped or suspended ? It would only be for a week or ten days. Also could it be a cause of my having to make a claim for universal credit upon return?
I visited her some years ago and notified the DWP that I was going and also the address and the assistance I received at airport etc to demonstrate there was nothing in making the trip that would contradict my reasons for being on ESA or DLA as it was then ( I am now on PIP). I seem to remember the rules were different if one was travelling outside the EU, which we were members of back then of course. If the country visited was within EU thus having a reciprocal agreement with UK the rules were rather more relaxed than if travelling to Canada or Australia etc. I wondered if now we are out of the EU, there are tighter restrictions on leaving the UK even though it is for less than 28 days and to an EU country.

I'm pretty sure I'm on a combination of contributions based and Income Related ESA (Long Story) The link you posted seems to only cover disability benefits PIP ad DLA but am I right in thinking that you are saying the ESA claim would stop if on IR ESA, regardless of amount of time out of the country or only if you exceed the 4 weeks limit?

Thanks Gordon. I thought so I went away for 2 weeks some years ago and informed them, nothing happened to affect my claim. I just wondered if anything had changed as we have left the EU since then

Hi Gary,
I'm also on Supported Group CB ESA. Does your reply mean that if a claimant is going away for less than 4 weeks they don't need to inform the DWP?

Is it any different for a claimant in receipt of DLA at lower/lower rates? What are the rules on foreign travel in that benefit?
