I have watched four of these from close enough to take notes. The sequence is remarkably consistent, and almost all the damage people take comes from the same three or four avoidable moves rather than from the closure itself.
Week one: extract, do not argue
Everything you can read today, you may not be able to read on day sixty-one. Download the full statement history as PDF and as CSV, every standing order and direct debit mandate, every payee on the list with full details, and any facility or loan documentation. Do it this week. Access is usually cut on the closure date without warning, and requesting historic statements from a closed account afterwards is a paid, slow, and occasionally refused process.
Then inventory what is attached to the account, because this is where people get hurt: payroll, tax payments, card acquiring settlement, subscriptions billing to the debit card, any supplier who has your details on file for a direct debit. Each one needs a new destination and each one takes a different amount of time to move.
Weeks one to three: open two, not one
Apply at two institutions in unrelated groups, at the same time. Two because one of them will take longer than promised and one of them may decline you, and you will not know which until late. Expect the new onboarding to be heavier than the account you are losing — the same underwriting climate that produced your letter produced their questionnaire.
When they ask why you are moving, the answer is that you are moving. You are under no obligation to volunteer that you were exited and volunteering it will not go well.
Day sixty and the balance
On the date, the account stops accepting credits and online access goes. The remaining balance is not usually withheld — the normal outcome is a transfer to a nominated account or a cheque, generally within one to three weeks. The exception, and it is the one to plan around, is that the exit and a hold are two separate decisions made by two separate teams. Which brings me to the thing not to do.
What turns an exit into a freeze
Do not empty the account in one movement the day after the letter arrives. A single large outbound transfer immediately following an exit notice is precisely the behaviour pattern that gets escalated, and an escalation replaces your orderly sixty days with an indefinite hold that has no notice period at all. Run the balance down through normal operating payments and move the residual near the end.
Also: card acquiring is a separate contract with a separate timeline, and it does not automatically die with the bank account. In two of the four cases I watched, acquiring was pulled six to twelve weeks after the bank exit, by a different company, for the same unstated reason. Plan for it rather than being surprised by it.
Caveat on all of the above: everything I have seen was UK and EU. I do not know how much of the sequence transfers elsewhere, and the tipping-off constraint that makes the silence mandatory is jurisdiction-specific.
Short version: export everything this week, open two replacements immediately, and drain the balance slowly.
