Notification of Performance Measurement visit

Hello, I have just received a letter from DWP notifying me of an appointment at my home next week. The letter states that they will visit my home between 09.00am and 3.00pm.
The purpose of the visit given is to review my benefit claim and to check that the DWP is paying me the correct amount of ESA.

So can anyone advise me about these type of visit and the real reason for them. And like so many people on this site it just adds to the worry and stress that we are already going through.
I would appreciate any help or advice please?

Hello Gordon
Thank you so much for your reply, and yes you are correct I am in the support group.
So what i am sure about is what i need to have for my visit apart from the 2 forms of identification?. Because i always thought that being in the support group it wasn't means tested in anyway?.

Are they also likely to ask me any questions on my medical condition as part of their visit?
It states on the letter that they will be coming to see me between 09.00am and 3.00pm, and I'm sure like many other people on this site that the worry, pain and stress that will cause to me will certainly not help especially if its 3.00pm when they arrive.

I look forward to your reply

Kind regards

Paul

Hello Gordon
Thank you for your reply and I forgot to mention that I am on CB ESA and also in the support group.
I receive a pension after being retired on the grounds of ill health and the amount is £120 per week. So how will that affect what I currently receive?. And do I still need to show bank statements or just proof of the pension I receive?. I have been on IB/ESA since 1997.
Also can I ask if any medical questions are likely to be asked on the day of the performance visit?
Regards
Paul
