Thanks ksand,
All the documents you’ve questioned and put a question mark next to I have no replacement for. That’s all I have which is listed. I have a lot outside of these dates. Collecting the mail I wasn’t originally concerned because at FLM(M) it was explained you could have correspondence in blocks of 4 months. As long as a piece of mail satisfied the blocks, not the exact month and week as this is.
I literally have no replacements and really panicking now
Don't panic - if you can't find anything else, you may just have to send what you do have.
Before that though, we can see if there's a way to make up documents that are 5 months apart.
Do you have monthly bank statements you've been sent in the post? What some people do is just make up the months they are missing with bank statements, since they are sent every month, so you can pick from whichever month you need.
If not, do you have anything from other months that you might be able to use, by shifting which months you provide documents for (which is why we recommend saving all your mail received every month so you can pick and choose which months you use).
For example, from the documents you've listed, you could try:
February 20171. Do you have anything from Feb 2017 instead of Jan 2017?
July 20172. Applicant - Bank Interest Summary Letter (19th July 2017)
2. Sponsor - EON Gas bill (27 July 2017)
Dec 20173. Applicant - Bank Credit Terms Change (November 2017) (not ideal but might be best option if you don't have anything from Dec)
3. Sponsor - NHS Referral Letter (7th December 2017)
May 20184. Applicant - Bank Saving Statement (15th May 2018)
4. Sponsor - Anything at all from May?
October 20185. Anything from October?
March 20196. Joint - Council Tax Bill (7th March 2019)
