Separate return support, employment records, asset history, contracts and routine duplicate copies. Records connected to property may matter beyond the purchase year. Legal, lender, insurance or other requirements can also differ from a general tax guideline.
Give files consistent dates, entity names and document types. Identify who approves disposal, how retained copies can be retrieved and what happens when an audit, dispute or other matter requires preservation. A tidy folder is useful only if the relevant evidence remains accessible.

No. Your record type and circumstances determine the policy. Check the current guidance and responsible adviser before disposing of evidence.
