Proof of links to the UK?

So I am about to send off my citizenship application to the Home Office, but within the last 12 months, I have exceeded the 90 day absence requirement by 10 days.

This prompted me to wait to send it off and contacted an immigration solicitor, which told em that my application will be considered (even if I meet all the other requirements) if I provide them, and I quote: "links to the UK through the presence of family, and established home and a substantial part of your estate"

With the establishment home, I could ask my parents a copy of the tenancy agreement of the house I have been living since I was 5, but for the rest apart from letters from my primary school, high school, college and university there is not much I can provide.

If someone has a more detailed list of documents that I can use to prove my links to the UK, it would be most appreciated...

Absence of 100 days in the final 12 months is NOT and issue.

Nothing you need to provide. The solicitor is confused

Sorry, I was meant to write that I was absent for an extra 15 days, Which would prompt me to prove my links to the UK.

Not required. You are overthinking.
