What Does SO Mean on a Bank Statement?

SO on a bank statement means Standing Order — a fixed, regular payment that you set up to send the same amount on a set schedule. It leaves your account automatically until you change or cancel it.

Here's exactly what a standing order is, why it appears, and how it differs from a Direct Debit.

Key Takeaways

• SO stands for Standing Order — a regular payment you set up yourself.
• You choose the fixed amount and the schedule, and it stays the same until you change it.
• It's often used for rent, moving money to savings, or paying the same person regularly.
• Because you control it, you can amend or cancel a standing order at any time through your bank.

What does SO mean on a bank statement?

SO is short for Standing Order. It's an instruction you give your bank to pay a fixed amount to the same account at regular intervals — weekly, monthly or otherwise.

The defining feature is that you are in control. You decide the amount, the recipient and the dates, and nothing changes unless you change it.

Why a standing order appears on your statement

You'll see an SO because you set one up, usually for a predictable, repeating payment. Common uses include:

• Rent. Many tenants pay a landlord or letting agent by standing order.
• Savings. Moving a set amount into a savings account each payday.
• Regular gifts or support. Sending the same amount to a family member.
• Club or membership fees where the amount never varies.

The statement line usually shows the recipient's name or reference next to "SO", so you can see who's being paid.

Standing order vs Direct Debit

This is the most common point of confusion. The difference comes down to who controls the payment.

With a standing order, you set a fixed amount and schedule, and only you can change it. With a Direct Debit (DD), you authorise a company to collect amounts that can vary.

Because a standing order is a fixed amount you control, it isn't covered by the Direct Debit Guarantee — but it also can't be changed by anyone else.

What to do if you don't recognise an SO

Since you set up standing orders yourself, an unfamiliar one is usually an old arrangement you've forgotten — a lapsed subscription-style payment or a transfer you meant to stop.

View it in your banking app to see the full payee details and amount. You can amend or cancel a standing order at any time through your app, online banking or your branch.

If you genuinely didn't set it up, treat it seriously and contact your bank straight away. For other unfamiliar entries, see what is this charge on my bank statement or, for incoming money, what does BGC mean on a bank statement.

Frequently asked questions

Is an SO money in or money out?

Money out. A standing order is a payment you send from your account to someone else.

Can I change the amount of a standing order?

Yes. Because you control it, you can change the amount or schedule whenever you like through your bank — the payment won't change on its own.

Is a standing order the same as a Direct Debit?

No. You control a standing order and its amount is fixed; a Direct Debit is controlled by the company collecting it and the amount can vary.

How do I cancel a standing order?

You can cancel it through your banking app, online banking or by contacting your bank — you don't need the recipient's permission.
