Thanks a mill, I'm glad to hear that worked for you.
We've got RTB confirmation, proof of payment in statements, and landlord references that have start/end dates. Hopefully that'll be us covered.

Started on the citizenship application, then had a busy summer, and they've gone and changed the form and proofs! Previously, Rent Agreement plus proof of payment was required. Now it's just Rent Agreement. While we have rent agreements for every home over the last 6 years, we haven't moved annually...
