Utility Payment Arrangements: The 21 Day Cadence That Turns Arrears Into Kept Promises
Ofgem tracks a number called accounts in arrears with no arrangement to repay the debt. That number is a job description. Here is the 21 day cadence that turns past due accounts into payment arrangements people actually keep.
Ofgem publishes a chart titled Number of accounts in arrears where there is no arrangement to repay the debt. Read that title again. It is a job description.
Utility payment arrangements turn a past due balance into a scheduled commitment the customer can meet. The cadence that works runs 21 days from the due date: a reminder by day 3, voice attempts on day 5 and day 8, the arrangement conversation around day 10, written confirmation inside 24 hours, and a prompt 48 hours before the first instalment.
Domestic energy debt and arrears older than 91 days reached 5.02 billion pounds in the most recent quarter reported, according to a written answer to Parliament from the Department for Energy Security and Net Zero.
The size of the arrears book is not the operational problem on its own. The share of it with no arrangement attached is.
Why the arrangement is the unit of work
A payment clears one invoice. An arrangement clears a pattern.
Most collections dashboards lead with cash collected this month. Cash is a lagging number. By the time it moves, the decisions behind it are six weeks old.
Arrangements created this week is a leading number. It tells you what next quarter looks like while you can still change it.
Count arrangements created, not euros collected. The euros follow.
Ofgem published guidance on behavioural strategies for reducing energy arrears in late October, drawing on trials across energy, water, tax, rent and consumer credit. The theme running through it is design: small changes to how and when you ask change what people do.
Stop here for thirty seconds. Pull one number from your billing system. Of the accounts that went past due sixty days ago, what share has an active arrangement on it today?
The 21 day utility payment arrangement cadence
Nine touches over three weeks. Each one has exactly one job. If a touch has no job, cut it.
Day 0. The due date passes. Do nothing. Bank files take two or three days to settle, and chasing money already in flight costs you trust and a call.
Day 3. Reminder by SMS or email. Amount, due date, payment link. One job: catch the people who simply forgot. In most books that is a third of the roll.
Day 5. First voice attempt. Under ninety seconds. Confirm the balance is real, check nothing is disputed, offer pay now or a date.
Day 8. Second voice attempt, different daypart. If day 5 went out at 10:00 on a Tuesday, day 8 goes out at 18:30 on a Thursday. Same list, different life.
Day 10. The arrangement conversation. Affordability first, instalment second. This is the call that earns the next three months.
Day 11. Written confirmation. Instalment amount, dates, payment method, and how to change it if something breaks. In the customer's language, inside 24 hours.
Day 13. Pre-instalment prompt, 48 hours out. The cheapest touch in the cadence and the first one teams drop.
Day 15. First instalment due.
Day 17. Broken promise follow up. Two days late, not two weeks. An arrangement that misses instalment one and sits unworked for a fortnight is finished.
Day 21. Review. Kept, reset once, or routed to a human collector for a different kind of conversation.
Most teams run day 3 through day 10 and stop there.
Day 11, day 13 and day 17 are where kept rate is won.
An arrangement with no reminder before the first instalment is just a diary note.
Why do payment arrangements break?
Re-defaults cluster hard on instalment one. Past that point, kept rates hold up well.
Four conditions separate an arrangement that survives from one that does not.
- The number came from the customer. If you proposed the instalment, you own the failure. Ask what they can put aside each month without missing something else, then work backwards.
- The date is specific. The 14th of the month beats end of the month every time. A named date creates a diary entry in someone's head.
- It is confirmed in writing inside 24 hours, in their language, with the payment method already set up.
- Something reminds them before instalment one lands.
Three of those four are admin. Only the first needs a skilled collector.
Four lines that change the arrangement conversation
Steal these, then have your compliance team mark them up before anyone says them on a live call.
The opener that is not a demand. I am calling about the account at [address]. The balance is [amount] and it is [n] days past due. Before anything else, is that figure right? It invites a correction, so disputes surface in the first fifteen seconds instead of on the fifth call.
The affordability anchor. What could you put towards this each month without missing something else? The customer picks the number, and that is the strongest predictor of whether they keep it.
The specific date close. So that is [amount] on the 14th of each month, starting the 14th of next month, by direct debit. Can I confirm that now? Amount, date, method and consent in one sentence.
The handoff line. This needs someone with more room than I have. Let me bring in a colleague now. No transfer limbo, and the customer never starts the story again.
What this looks like on a real floor
An illustrative example, not a customer.
Picture a municipal gas and electricity supplier in Bavaria. Around 60,000 domestic accounts, a credit team of seven, roughly 2,400 accounts rolling past due each month.
Seven collectors can hold maybe 1,200 right party conversations in a month. Half the roll gets a letter and silence, so the team triages, and new arrears always win because that is where the recoverable money looks like it is.
The day 13 prompts stop going out. Day 17 calls slide to day 25. Arrangement set-up rate on the dashboard still looks healthy, because arrangements are still being created.
Then first instalment kept rate drifts down four points over a quarter and nobody can name the decision that caused it.
Nobody decided to drop the day 13 prompt. It just stopped happening on the weeks that were busy.
That is the failure mode, and it has nothing to do with collector skill. The cadence just depends on who happens to be free at six in the evening.
Where a voice AI worker fits in the cadence
Split the cadence into fixed path and judgement.
Fixed path: day 3, day 5, day 8, day 13 and day 17. High volume, strict timing, no discretion needed. This is the work that disappears first when inbound spikes.
Judgement: day 10 when the balance is large or the story is complicated, and day 21 when the account needs a different route. Keep your collectors there.
Put the fixed path on a voice worker so your people keep the conversations that need a person: hardship, disputes, vulnerability, anything where policy runs out.
AutoNurture.AI runs past due reminders on cadence in 12 plus languages, negotiates payment plans inside the policy your finance team sets, sends tokenised payment links so no card data is spoken on the call, and writes the outcome back to your CRM per call.
Dial windows per market, retry logic and do not call rules run automatically from the workbench, which is what keeps day 13 and day 17 alive through a busy fortnight.
Escalation is the part worth testing hardest. When a call turns into a negotiation or a risk signal appears, the hybrid human and AI dialer hands it to a human seat in under two seconds with the transcript and the account already on screen.
For utilities the plumbing sets the timeline, so check the integration list first. SAP IS-U, powercloud, Schleupen.CS and Oracle Utilities CC&B sit alongside the usual CRM and payment providers.
The utilities and energy playbook walks the collections workflow end to end, and what each worker does covers the rest of the platform.
If you would rather judge the tone than the feature list, there are recorded calls in German, Portuguese and Italian, including one where an unpaid 140 euro invoice becomes four instalments of 35 euro.
Before you automate the cadence
Practical, not alarming. Walk this once, then get it signed off.
- Write the arrangement policy down before you automate it. Minimum instalment, maximum term, what needs approval. A voice worker can only hold a limit that exists in writing.
- Disclose the AI at the start of the call, in the customer's language, and give a route to a human without the customer having to ask twice.
- Read vulnerability and do not call flags from the source system before dial, not after.
- Set retention on recordings and transcripts, and be able to evidence the deletion job.
- Confirm where audio and transcripts are processed, not only where they are stored.
Your obligations depend on your market and your regulator. Check with your compliance team before you change anything customer facing.
How to measure utility payment arrangements
Four numbers. All four come out of a billing extract, a dialer export and a payments file.
- Arrangement set-up rate. Arrangements created divided by accounts entering arrears in the same window.
- Time to arrangement. Median days from due date to arrangement created. Single digits is the target.
- First instalment kept rate. Arrangements where instalment one landed on time, divided by arrangements created.
- Re-default rate at 90 days. Arrangements that stopped, divided by arrangements created a quarter earlier.
If first instalment kept rate sits below your overall kept rate, look hard at the day 13 prompt before you touch the script.
If time to arrangement is above fifteen days, you have a capacity gap to close first.
A four week test that will survive finance
- Week one. Pick one segment. One balance band, one language, one market. Leave everything else alone.
- Week two. Add the day 11 confirmation and the day 13 prompt to that segment only. Change nothing else.
- Week three. Add the day 17 broken promise call.
- Week four. Compare the segment against a matched holdout worked the old way, same balance band, same period.
Then decide. If first instalment kept rate moved and complaints did not, widen the segment. If it did not move, the day 10 conversation is where the work is.
One segment, one holdout, one month. That is an argument a CFO cannot wave away.
What to do next
Map your current cadence against the 21 days above and mark every touch that only happens when the floor is quiet. That list is your automation shortlist.
Then Book a demo and bring one of your own arrears segments. Twenty minutes, a live call in your language, your script rather than a deck.
Frequently asked questions
What is a utility payment arrangement?
A utility payment arrangement is a scheduled plan that clears a past due energy, water or telecom balance over an agreed term, usually in fixed monthly instalments set against what the customer can afford. Regulators track how much arrears sits with no arrangement attached.
How long should a payment arrangement cadence be?
Twenty one days from the due date covers it. A reminder on day 3, voice attempts on day 5 and day 8, the arrangement conversation around day 10, written confirmation on day 11, a prompt on day 13, the first instalment on day 15 and a broken promise follow up on day 17.
Why do promise to pay arrangements break?
Most break at instalment one. The usual causes are an instalment the collector proposed instead of the customer, a vague date such as end of the month, no written confirmation, and no reminder in the 48 hours before the first payment.
Can AI voice agents set up payment arrangements?
Yes, within limits you define in advance. A voice worker can confirm the balance, negotiate inside a written policy on minimum instalment and maximum term, send a tokenised payment link and log the outcome, then hand anything outside policy to a human collector mid call.
What should go to a human collector?
Hardship, disputes, bereavement, any vulnerability flag, balances above your escalation threshold and any case where the customer asks. Fixed path reminders and follow ups are what automation is for.
How do you measure whether arrangements are working?
Track arrangement set-up rate, time to arrangement, first instalment kept rate and re-default rate at 90 days. If first instalment kept rate lags your overall kept rate, the gap is in the reminder before instalment one rather than in the script.
