What you can actually do when a council pays late
You have three levers, and most agencies pull none of them. You can charge statutory interest and fixed compensation on the overdue invoice, you can reconcile and challenge what the council has actually paid against what it agreed, and you can run a credit control rhythm that catches a slow invoice at day 15 instead of day 75. The interest is the headline. The rhythm is what actually changes your bank balance.
This guide is written by LOYALS, a King's Cross firm of chartered accountants that runs weekly payroll and council invoicing for London home care agencies, so the examples below are the ones we deal with on real ledgers, not textbook theory. If you run a domiciliary agency with heavy council or Integrated Care Board (ICB) income, this is the single biggest cash problem you face, and it is fixable.
Start with the legal position, because it is stronger than most owners think. Under Regulation 113 of the Public Contracts Regulations 2015, every contracting authority, which includes a council, must pay a valid, undisputed invoice within 30 days. Not 45, not "when the finance team gets to it". The same 30-day term is supposed to flow down the supply chain, and councils have to publish how much of their invoicing they pay inside 30 days and how much late-payment interest they owe. The rule exists. The problem is that nobody enforces it for you.
Our matched work here is with the commercial team behind care agency accountants, the outsourced finance department we run for home care providers, where council credit control is one of the jobs we take off the owner entirely.
Why late council payment quietly wrecks a care agency
Late council payment does not usually kill an agency with one big shock. It bleeds it slowly. Your carers are paid weekly or fortnightly at the £12.71 National Minimum Wage or above, your pension and employer National Insurance go out on the same clock, but the council income that funds all of it lands 60, 70, sometimes 90 days after the care was delivered. That gap is the whole problem, and it grows with every new package you win.
Here is the maths that catches owners out. A domiciliary agency delivering £120,000 of council care a month, paid on average 70 days after invoice, is carrying roughly £280,000 of its own money in unpaid invoices at any moment. Win more work and that number goes up, not down. Growth makes the cash hole deeper, which is why care agencies so often feel busiest and most broke at exactly the same time.
The visible symptom is the overdraft or the director's loan quietly topping up the wage run. The hidden symptom is worse: an owner who cannot say, on any given Monday, which council invoices are genuinely late, which have been part-paid, and which are stuck in a dispute nobody has chased. When the numbers are not reconciled, the gap gets papered over with borrowing instead of being fixed at source.
The chart above is the pattern we see most often. Nothing about the council changes. What changes is that someone starts raising invoices cleanly, reconciling every payment, and chasing on a schedule. The 30-day legal term is the gold line the agency moves toward, and even getting from 72 days to 38 releases tens of thousands of pounds of the owner's own cash back into the business.
The interest and compensation you are legally owed
When a council pays an undisputed invoice late, you are entitled to charge interest and a fixed sum on top, automatically, without it being written into the contract. The right comes from the Late Payment of Commercial Debts (Interest) Act 1998, and it applies to public bodies exactly as it applies to private clients.
Two things are payable. The statutory interest rate is 8 percent above the Bank of England base rate. With the base rate held at 3.75 percent as at August 2026, that is 11.75 percent a year on the overdue amount, running from the day after the due date. On top of that you can claim a fixed sum per late invoice: £40 where the debt is under £1,000, £70 from £1,000 to £9,999.99, and £100 for £10,000 or more. You claim both on the same invoice. The government sets these out in its guidance on late commercial payments.
Make it concrete. Say a council holds a £14,000 care invoice for 45 days past its due date. The interest is £14,000 at 11.75 percent for 45 days, which is about £203, and you add the £100 fixed sum, so roughly £303 on one invoice. That does not sound like much on its own. Now picture it across a portfolio where £40,000 of council income routinely sits past due every month. The interest entitlement alone runs into the thousands over a year, before the fixed sums.
So why does almost nobody charge it? Two reasons. First, most agencies cannot prove the invoice was undisputed and exactly when it fell due, because their records are not tight enough. Second, owners worry about the relationship with a commissioner they depend on. Both are real, and both are why the interest is best used as a lever rather than a first move: a clean, well-evidenced account lets you raise interest as leverage in a payment conversation, and occasionally charge it, from a position of strength. One practical note from the accounts side, the interest and compensation you do recover are taxable income of the business, so they run through your figures like any other receipt. That is a reason to record it properly, not to skip it.
Remittance disputes: where the money really goes missing
The money you lose to a council is rarely the invoice it refuses outright. It is the invoice it part-pays without telling you why. A council almost never pays one invoice, in full, on one date. It runs batch payments and sends a remittance advice, the note that lists which invoices, or parts of invoices, are in that run. If you do not reconcile that remittance advice line by line against what you billed, genuine short-payments hide inside a payment that looks, on the bank statement, like it arrived.
Why do councils short-pay? Almost always because the hours you invoiced do not match the hours their system says were authorised, not because the care was not delivered. The usual causes are familiar to any registered manager: a purchase order that ran out halfway through the month, a package that was reduced or increased part way and never re-issued, a hospital admission that paused a package, or a rate uplift that was agreed verbally but never loaded onto the council system. Each one produces a quiet gap between what you are owed and what lands.
The fix is unglamorous and it works. Match every invoice to the approved care hours and the live purchase order before it leaves your building, so it goes out clean. Then reconcile every remittance the day it arrives, flag any line that is short, and query it inside the contract while the detail is fresh and the funder can still trace it. Left for three months, a short-payment becomes almost impossible to recover because nobody at the council remembers the package change. Caught at day 31, it is usually just corrected on the next run.
This is also where welfare VAT trips agencies up. Regulated personal care is exempt from VAT under HMRC VAT Notice 701/2, so a straightforward council care invoice carries no VAT. If you also run a standard-rated arm, introductions or the supply of staff, those lines do carry 20 percent VAT and a council will reconcile them differently. Mixing the two on one invoice without splitting them cleanly is a reliable way to get part-paid. For the wider picture on where that line sits, see our guide on whether domiciliary care is VAT exempt.
The monthly credit control rhythm that gets you paid
A credit control rhythm is simply a fixed set of actions that happen on set days for every council invoice, whether or not anyone feels like chasing that week. That last part is the point. Agencies that chase "when cash gets tight" always chase too late, because by the time cash is tight the invoice is already 60 days old and the person who could have fixed it has moved on. A rhythm takes the decision out of it.
Here is the cadence we run for home care agencies, mapped from the day an invoice is raised to the day it is either paid or formally recovered.
Read across the rhythm and notice what happens before the invoice is even due. By day 15, halfway to the deadline, someone has already confirmed the invoice is sitting on the council payment run rather than lost in an inbox. That single check catches most of the invoices that would otherwise silently miss the 30-day term. By day 31 the remittance is reconciled while the detail is still fresh, and only the genuinely stuck items reach day 45, where a firm, evidenced escalation with a mention of statutory interest tends to move them.
None of this needs a big team. It needs the same actions to happen on the same days every month, and it needs someone whose job it is to do them. When that person is the owner, it slips, because the owner is running care. When it is a finance function, it does not.
When to bridge the gap with invoice finance
Invoice finance can bridge the council cash gap, but only once the credit control underneath it is clean. Factoring or invoice discounting advances a percentage of an approved invoice within a day or two, so instead of waiting 70 days for the council you get most of the cash almost immediately and the lender waits to be repaid when the council pays. For an agency whose whole problem is the gap between paying carers now and being paid by the council later, that is a genuinely useful tool.
The catch is that a lender only advances against clean, undisputed invoices. If your invoices are unreconciled, part-disputed or not matched to approved hours, finance stalls in exactly the same places your cash does, and you end up paying a facility fee for a problem it cannot solve. Fix the invoicing and the credit control first, then finance amplifies a working system rather than propping up a broken one. We walk through the mechanics, the cost and the reconciliation in our guide to invoice finance for home care agencies, and the wider cash-flow discipline behind it in our note on accounting for NHS and ICB contract income.
There is a regulatory angle owners sometimes miss, too. As a CQC-registered provider, your financial viability is not a private matter. The Care Quality Commission (CQC) considers financial sustainability at registration and, for larger providers, under its market oversight regime, and a business that cannot fund its own wage run is a business the regulator worries about. Getting paid on time is not just a cash-flow nicety. It is part of showing CQC you can run safely.
Here is how the three common approaches to council late payment actually compare for a home care agency:
| What council credit control needs | Chasing on a spreadsheet | Generic accountant | LOYALS specialist |
|---|---|---|---|
| Matches each invoice to approved hours and the purchase order | ✗ Done by hand, if at all | ● Only at year end | ✓ Before the invoice goes out |
| Reconciles the council remittance advice line by line | ✗ | ✗ | ✓ Every run |
| Knows the 30-day Reg 113 term and statutory interest | ✗ | ● In theory | ✓ Used as leverage |
| Chases on a fixed weekly rhythm, not when cash runs low | ✗ | ✗ | ✓ Built into the month |
| Splits welfare-exempt care from standard-rated lines correctly | ✗ | ● Sometimes | ✓ On every invoice |
| Open Mon to Sat for an urgent commissioner dispute | ✗ | ✗ Mon to Fri 9 to 5 | ✓ 10am to 7pm Mon to Sat |
This is why home care agencies with heavy council income move credit control to a specialist rather than carrying it on the owner's laptop.

What to do before your next council payment run
If council late payment is quietly eating your cash, the practical steps are clear and most of them cost nothing to start.
- Age your council debt today. Pull a list of every council invoice outstanding and how many days old it is. If you cannot produce that in five minutes, that is the first problem to fix, because you cannot chase what you cannot see.
- Reconcile the last three remittances. Go back over the last few council payments and match them line by line to what you invoiced. The short-payments you find are money you are owed and had written off without noticing.
- Fix the invoice at source. Make matching each invoice to approved hours and the live purchase order a step that happens before it is sent, not a dispute you have afterwards.
- Set the rhythm. Put the day-15 payment-run check, the day-31 reconciliation and the day-45 escalation into a fixed weekly routine that runs whether or not cash is tight.
- Know your interest position. Work out the 11.75 percent statutory interest and the fixed sums on your worst offenders, so you can raise it as leverage in a payment conversation from a position of evidence.
- Only then look at finance. If the gap is still too big once the invoicing is clean, invoice finance can bridge it. Not before.
None of this is exotic. It is a routine, run by someone whose job is the money so the owner can get back to running the care. LOYALS runs weekly payroll, council invoicing and credit control for London home care agencies, which means the reconciliation and the chasing happen every week in the background rather than in a panic the week before payroll. You can check your own agency's position in a free call with LOYALS, and walk away knowing whether you have an interest claim, a reconciliation problem, or both.
