Universal credit appointment -commitment review

Yolo40oops

Hi, I have migrated from tax credits to UC at start of the year and all going fine. I work full time, single mum of 2 and have just received an appointment to attend the job centre for a commitment review but no idea why?
I recently got temporary promotion so my pay has increased and it was not updated by my employers HR for 2 months so had a larger pay due to it being backdated so did not qualify that month for uc. I subsequently then got a backdated pay rise which meant I was not eligible again for uc next month.  However on a normal months pay I am eligible, could this be it?
Anyone any idea what to expect and if I need to bring anything please. 

Thanks for reading

A Commitments Review appointment is usually booked when you've moved into the Intensive regime and that is usually triggered by you having earnings below the AET (£892) in the previous assessment period.  

Take a look at your statement for the last Assessment period.  What earnings were taken into account on that last statement?

That makes perfect sense as my August uc payment is way more than expected and on checking they haven’t taken any deductions of for my earnings. I added a note to my journal to get them to look into as worried I will be overpaid. Thank you for you help
