Pop into the Post Office®
If you have a 1st Account, you can use your debit card to check your balance, pay in and withdraw cash (which will count to your daily limit) at any of the 11,500 UK Post Office® locations across the UK. To find your nearest office or check opening times: Branch Finder | Post Office Opens an overlay [Will show a security message first].
You can pay in coins over the counter as long as they are don't exceed the coin bag limit, and are not mixed coins, up to the value of £25 per transaction.
To pay in cheques, use a pre-printed first direct credit slip, from your paying-in book. You'll also require a HSBC Post Office® cheque deposit envelope - which you'll find on the Post Office® counter. Do not put cash in the deposit envelopes.
Cheques paid into the Post Office® may take a day longer to reach your account than cheques paid in at HSBC branches - and this is assuming you do it before the Post Office® branch cut-off time. They'll be able to tell you when this is.
