Three situations lie behind this question: a client with no UK bank account, a client whose account won't accept direct debits, and a client who simply doesn't want one. Each leaves you with a different second-best, and none of the alternatives gives you what a mandate gives you, so what helps is knowing which part you're giving up.
In this article
The short version
- Direct debit runs on Bacs, so your client needs a UK account that accepts direct debits.
- The scheme's own rejection codes include "invalid account type" and "bank will not accept direct debits on account", so some accounts are ruled out by the bank and not by your client.
- A standing order keeps the client in control: Bacs says "the control of the payment date and amount rests with the customer".
- Providers report that a cancelled or amended standing order doesn't generate a notice to you, and no scheme or bank page states it either way.
- Variable Recurring Payments are the closest open banking equivalent to a mandate, and general invoice collection isn't in the first wave.
- Invoices created with a mandate already in place are paid 97.0% of the time, against 90.3% without one, measured on 152,689 payment requests created in the seven months to 31 January 2026 (Adfin platform data).
Who genuinely can't
Start with the cases where the answer has nothing to do with willingness.
A client with no UK bank account can't give you a UK direct debit instruction, because the scheme is a domestic one. The euro area has its own direct debit scheme for euro accounts, and that's a separate arrangement with separate rules, so treat an overseas client as a payment-method question and not a mandate question.
Then there are accounts that exist but won't take a collection. The scheme's own rejection codes make this concrete: alongside "no account" and "account closed" you'll find "invalid account type" and "bank will not accept direct debits on account", plus "transaction disallowed at payer's branch". Those codes exist because banks do refuse direct debits on particular accounts, most often savings and certain specialist or client accounts. Which accounts, in any particular bank, is a question for your client's bank rather than for you, and asking early saves a failed lodgement later.
Two smaller cases deserve separating out, because they look like refusals and aren't. A client whose account details keep coming back as incorrect has an administrative problem you can fix, and a client whose signatory is unavailable has a timing problem. Neither needs an alternative payment method, only a second attempt.
The client who'd rather not
Plenty of clients can give you a mandate and would prefer not to. Often that's a policy rather than a preference: payments go out on a fixed run, or every invoice needs a purchase order, or two people have to approve anything leaving the account. Sometimes a finance director simply wants to keep the timing decision on their side of the table.
That's a legitimate position, and it's usually more productive to work with it than to argue it. A business that approves payments in a weekly run isn't refusing to pay you, it's refusing to be collected from outside its own controls. What you can reasonably ask for is a firm date and a method that makes paying on that date take seconds.
With an existing client base the announcement is usually harder than the mandate, so if you want wording you can borrow, how to tell clients you're moving them to direct debit has it. New clients never need the announcement at all, because you ask at signature, and making direct debit part of signing the engagement letter covers what that looks like in practice.
What each situation leaves you with
| Situation | What tends to work | What you give up |
|---|---|---|
| No UK bank account | Card or wallet payment from a link, or a bank transfer with clear reference instructions | Automatic collection, and you carry any currency and cross-border cost on the card side |
| Account type won't accept direct debits | Standing order for a fixed fee, or a link per invoice for variable ones | The right to vary the amount without your client acting |
| Fixed monthly fee, client wants control | Standing order, with a diary check that it arrived | Notice when it's cancelled or amended |
| Variable fees, client wants control | A payment link on every invoice, with reminders behind it | Certainty of date, since the payment still needs a human decision |
| Large one-off invoice | Card, open banking or transfer, or an instalment plan by agreement | Nothing you had; a mandate was never likely here |
| Client pays on a fixed payment run | A link plus a due date aligned to their run | Little, if the date and the run actually match |
Standing order, and what it costs you in visibility
A standing order is your client instructing their own bank to send a fixed amount on fixed dates. For a flat monthly fee it's the closest thing to a mandate you can get without one.
The trade is control. Bacs puts it in one line: with a standing order "the control of the payment date and amount rests with the customer". Your client can change or cancel it without telling you, and providers report that no advice reaches you when they do, which is different from direct debit, where a cancellation arrives as an ADDACS message. No scheme or bank page we could find states the standing order position either way, so we describe it as providers describe it.
Practically, that means a standing order needs a monthly check that the money arrived, and a fee change needs a conversation and then a new instruction from your client. Our comparison of direct debit and standing order goes through the differences properly.
A payment link on every invoice
Where fees vary, a link on the invoice is the workhorse. Your client pays by card, Apple Pay, Google Pay, open banking or bank transfer, in whichever way suits their controls, and the payment reconciles against the invoice it came from.
You're still relying on somebody deciding to pay, so the sequence behind the link matters more than it does with a mandate. Among customer-initiated payments on Adfin, card payments arrive on or before the due date 65.1% of the time, bank payments 62.0% and bank transfers 57.9%, measured on 59,777 paid customer-initiated payment requests over 26 months (Adfin platform data). Hold the business constant and those gaps largely close, so read it as a difference between the businesses and customers using each method more than as a property of the method.
What a link removes is the fiddly part: no account number to copy, no reference to get wrong, no logging in to a portal. Payment links covers the mechanics.
Open banking, and the thing that isn't ready yet
Open banking, or pay by bank, is a single authorised transfer your client approves inside their own banking app, so the details come from you and there's nothing for them to mistype. It settles fast and carries no chargeback exposure, and it suits a client who dislikes handing over card details or a mandate.
Variable Recurring Payments are the piece that would genuinely replace a mandate, letting a client set limits once and then be collected from within them. The UK Payments Initiative scheme launched in June 2026, and the regulator's first wave covers utilities, financial services and payments to central and local government. General invoice collection isn't in it, so for now this belongs on your watch list. VRPs and what they change tracks where it's got to.
How much of the mandate you're giving up
Being straight about this helps you decide how much energy to spend on the conversation. On Adfin, invoices created when a mandate was already in place are paid 97.0% of the time, against 90.3% where there was no mandate, and 1.3% are still open after six months or more, against 5.4% (Adfin platform data). That's measured on 152,689 non-deleted payment requests created in the seven months to 31 January 2026.
Read it as a comparison between two populations, since clients who agree to a mandate may differ from those who don't in ways the figures can't separate. The direction still matters: without a mandate, more of your invoices stay open for longer, and the work of closing them lands on you.
So for a client who can't or won't use direct debit, you're accepting a bit more collection work in exchange for keeping the relationship comfortable. Pricing that in, by aligning due dates to their payment run and putting a link on every invoice, is usually a better use of your time than a second attempt at persuading them.
Common questions
Why would a client be unable to set up a direct debit? Usually one of three reasons: no UK bank account, an account the bank won't allow direct debits on, or a policy that keeps payment approval inside their own process. The scheme's rejection codes include "invalid account type" and "bank will not accept direct debits on account".
Can you take a direct debit from a non-UK bank account? Not through the UK scheme, which is domestic. The euro area runs its own direct debit scheme for euro accounts under separate rules, so an overseas client is better handled with a card, wallet or transfer payment from a link.
Is a standing order a good substitute for direct debit? For a fixed recurring fee it works, with two catches. Bacs says the control of the date and the amount rests with your client, and providers report you get no advice when a standing order is cancelled or amended, so you need your own check that the money arrived.
What's the best option for a client with variable monthly fees? A payment link on each invoice, with a reminder sequence behind it. You keep the ability to bill different amounts, and your client keeps the approval step their own process requires.
Can open banking replace a direct debit mandate? Not yet for invoicing. A single open banking payment is authorised once by your client, and the recurring version, Variable Recurring Payments, launched in June 2026 for a first wave covering utilities, financial services and government payments. General invoice collection isn't included.
Should you charge more for clients who won't pay by direct debit? That's a commercial decision, and the rules differ by method: surcharging consumer cards is banned, while a cost-based charge on a commercial card is permitted. Our guide to payment surcharges sets out what UK law allows before you price anything differently.
