Payment reminders UK (2026): 4-stage sequence, Bank Rate + 8% and templates

This is a practical UK guide for tradespeople and small suppliers on payment reminder sequences, timing and copy-ready templates. It is not legal advice. Rules change; confirm on GOV.UK before you claim interest, send a Letter Before Action, or issue court proceedings.

Sister pages (keep these aligned — do not contradict them):

This page owns the reminder calendar, stage-by-stage wording, subject lines and what to attach. The chase page owns relationship tone and channel choice once things go quiet.

Quick answer: the 4-stage reminder sequence

Checked on 2 September 2026: Bank of England Bank Rate is 3.75% (held through mid-2026 MPC decisions; next decision due 17 September 2026). For eligible business-to-business debts under the Late Payment of Commercial Debts (Interest) Act 1998, statutory interest is Bank Rate + 8% — currently 11.75% simple interest — plus fixed compensation of £40 / £70 / £100 per late invoice. That statutory route does not automatically apply to consumers / homeowners.

InvoiceAdept helps UK trades raise invoices, schedule Pro reminders, and keep digital records. It does not file Money Claim Online, County Court claims, VAT returns, Self Assessment, Making Tax Digital updates, or CIS300 returns.

Why unstructured reminders stall cash flow

You finished the job. The invoice left your phone. Then the awkward bit starts: staring at an unpaid line and deciding whether today’s “just checking in” email will help or annoy.

Most reminder sequences fail for three boring reasons — not because you are “too soft” or “too aggressive”:

1. Too late. The first chase arrives weeks after the due date, when the purchase ledger has already closed the period and your invoice is no longer in the pile that gets paid this week.

2. Too vague. “Friendly reminder your invoice is outstanding” without invoice number, amount, due date, days late, or how to pay forces the recipient to dig. Busy finance teams defer digging.

3. No calendar. Ad-hoc chases depend on how awkward you feel that morning. A fixed sequence removes the emotion and creates an audit trail if you ever need a Letter Before Action.

This rewrite removes earlier unsourced survey claims and invented percentage uplifts that previously appeared on this URL. Stick to GOV.UK, the Bank of England, and the Office of the Small Business Commissioner (OSBC) when you state rights or rates.

Know the customer type before you write stage 3

Tone and legal wording change with who signed the paperwork. Get this wrong and you either under-claim (on a commercial debt) or over-claim (on a domestic job).

If there is a genuine dispute (scope, snagging, unsigned variation), OSBC guidance is that you cannot charge statutory interest and compensation on an invoice paid late because of a dispute. Sort the undisputed balance first; chase only what is agreed.

Many UK tradespeople also find it helpful to review How to chase late invoice payments UK at this stage.

The 4-stage payment reminder calendar (detail)

Adapt for job size and relationship. A trusted commercial client one week late after years of on-time payment may get a phone call before stage-3 interest language. A new main contractor who ghosts a five-figure completion invoice should not skip documentation.

Compress the soft steps for small undisputed balances. Stretch them for a long-standing client with a temporary cash squeeze — but do not skip the written record.

Why stage 1 (pre-due) is the one most trades skip

A short note three days before the due date does two jobs:

• It puts the payment back on the client’s or purchase-ledger’s radar while there is still time to process BACs in the same week.

• It removes the polite fiction of “we never saw it” — you have a timestamped reminder before it was late.

You are not chasing yet. You are being organised. That distinction matters for relationships.

Stage 1 template: pre-due reminder (3 days before)

Subject line ideas:

• Invoice #[NUMBER] for £[AMOUNT] due [DAY DATE]

• Heads-up: invoice #[NUMBER] due [DATE]

• Payment due [DATE] — invoice #[NUMBER]

Body (copy and adapt):

> Hi [Name], > > Just a heads-up that invoice #[NUMBER] for £[AMOUNT] is due on [DAY DATE]. > > If you have already arranged payment, please disregard this. Otherwise the bank details / payment link are on the invoice (also below). > > Sort code: [XX-XX-XX] > Account: [XXXXXXXX] > Reference: [INVOICE NUMBER or job reference] > > Thanks, > [Your name] > [Business name] > [Phone]

Keep it short. No interest language. No apology for asking to be paid for work already done.

Stage 2 template: due-day reminder

Send only if the invoice is still unpaid on the morning of the due date (or end of day if you invoice large commercial clients who pay on a batch run).

Subject line ideas:

• Invoice #[NUMBER] due today — £[AMOUNT]

• Due today: invoice #[NUMBER]

• Payment due today — #[NUMBER]

Body:

> Hi [Name], > > Invoice #[NUMBER] for £[AMOUNT] is due today ([DATE]). > > Please arrange payment using the details on the invoice, or reply if there is anything you need from us (PO number, timesheets, CIS statement, or a fresh PDF). > > Bank / payment link: [DETAILS] > Reference: [INVOICE NUMBER] > > Thanks, > [Your name]

Still no interest threat. Offer to unblock admin friction — missing PO numbers cause more “late” commercial invoices than bad faith.

Stage 3 template: first overdue (7 days late)

Tone shifts from informational to expectant. You are chasing. For B2B, you may mention the Late Payment of Commercial Debts (Interest) Act 1998 and your right to charge statutory interest at Bank Rate + 8% plus fixed compensation. You do not need to shout. Naming the right is usually enough.

Subject line ideas:

• Overdue: invoice #[NUMBER] — £[AMOUNT] (7 days)

• Invoice #[NUMBER] now 7 days overdue — action required

• Payment overdue — invoice #[NUMBER]

Body (B2B commercial debt):

> Hi [Name], > > Invoice #[NUMBER] for £[AMOUNT] was due on [DUE DATE] and is now 7 days overdue. > > Please arrange payment today. Bank details / payment link: [DETAILS]. Reference: [INVOICE NUMBER]. > > Under the Late Payment of Commercial Debts (Interest) Act 1998, we are entitled to charge statutory interest at the Bank of England Bank Rate plus 8% (currently 11.75% simple interest while Bank Rate is 3.75%) plus fixed compensation on overdue commercial debts. We would prefer not to add interest and would appreciate payment by return. > > If there is a query or a different remittance contact we should use, please let us know. > > Thanks, > [Your name]

Body (consumer / homeowner — do not claim statutory Late Payment Act rights):

> Hi [Name], > > Invoice #[NUMBER] for £[AMOUNT] was due on [DUE DATE] and is now 7 days overdue. > > Please arrange payment using the details on the invoice, or reply if something is outstanding from our side (snagging list, certificate, or a new copy of the invoice). > > Thanks, > [Your name]

Daily interest example while Bank Rate is 3.75% (statutory annual rate 11.75%, simple, ÷ 365 — GOV.UK style):

Formula: Daily interest = amount × 0.1175 ÷ 365. Round sensibly when you invoice interest separately. Full worked examples and the six-month reference-date rule: How to calculate late payment interest UK.

Stage 4 template: formal demand (14+ days late)

If stages 1–3 have not produced payment (or a credible payment plan), move to a formal written demand. This is still short of a full Letter Before Action, but it should look like a document that could sit in a court file: facts, amount, days late, how to pay, and a clear deadline.

Subject line ideas:

• Formal demand: invoice #[NUMBER] — £[AMOUNT] now [N] days overdue

• Outstanding debt: invoice #[NUMBER] — payment required within 7 days

• Notice of overdue payment — #[NUMBER]

Body (B2B):

> Hi [Name], > > Formal payment demand > > Invoice #[NUMBER] dated [INVOICE DATE] for £[AMOUNT] was due on [DUE DATE] and is now [N] days overdue. > > Please pay £[AMOUNT] within 7 days of this email (by [DEADLINE DATE]). > > Payment details: [BANK / LINK] > Payment reference: [INVOICE NUMBER] > > For business-to-business debts we reserve the right to charge statutory interest under the Late Payment of Commercial Debts (Interest) Act 1998 at Bank Rate + 8% (currently 11.75% while Bank Rate is 3.75%) and fixed compensation of £[40/70/100] as set out on GOV.UK, and to issue a separate interest-and-compensation invoice. > > If payment is not received by the deadline we may proceed to a Letter Before Action and, if necessary, a court claim for the debt. > > If you have already paid, please send remittance advice. If there is a dispute, please set it out in writing so we can address any undisputed balance separately. > > [Your name] > [Business name] > [Address / company number if limited]

After stage 4, follow the relationship-safe escalation on the chase late payments guide: phone confirmations in writing, separate interest invoice where appropriate, then Letter Before Action with a typical 14-day pay-or-proceedings window before considering Money Claim Online.

Subject lines and body rules (all stages)

You do not need invented open-rate percentages. You need clarity.

Do: include invoice number and amount; state due/overdue status plainly; keep subjects short; match the stage (heads-up → due today → overdue → formal).

Don’t: send “just a friendly reminder…” with no number; use vague “following up”; shout in ALL CAPS; reuse the same woolly subject every time.

Body rules for stages 1–2 (and usually 3): three to six short sentences; always include invoice number, amount, original due date, days late (from stage 3), how to pay, and a reply invite for admin blockers; put bank details or a payment link in the message itself; no sarcasm or guilt trips; keep a timestamped trail in your inbox or invoicing tool.

What the law says: statutory interest and fixed compensation (B2B)

GOV.UK’s interest page states that statutory interest for late commercial payments is 8% plus the Bank of England base rate for business-to-business transactions. You cannot claim statutory interest if a different interest rate in the contract is the applicable remedy (and public-authority contracts cannot push you below the statutory floor).

Checked 2 September 2026:

Fixed compensation (separate from interest) per late commercial invoice:

Source: GOV.UK debt recovery costs. Compensation is a fixed £ sum. Interest is a separate %. Do not merge them into one misleading column.

Which Bank Rate applies? The six-month reference rule

You do not always use “today’s” Bank Rate for a claim. OSBC’s interest calculator guidance uses:

For debts becoming overdue in 2026, both halves currently point at 3.75% → 11.75%. If Bank Rate moves after a reference date, that change does not rewrite the rate for debts that already became late in that half-year. Confirm on the BoE history page before you issue an interest invoice.

Older wrong figures on this URL: previous copy claimed Bank Rate 4.5% and statutory interest 12.5%. Those figures are out of date. Use 3.75% / 11.75% while Bank Rate remains 3.75%.

Phone, automation and prevention (around the four stages)

Email builds the audit trail. A two-minute call often unlocks the BACs the same afternoon — especially at day 7 or day 14 if emails are unread.

Call script: “Hi [Name], calling about invoice #[NUMBER] for £[AMOUNT], due [DATE], now [N] days overdue. Is there anything blocking payment, or can you confirm when it will go out?”

• “Forgot — I’ll do it today” → one-line written confirm with amount and reference.

• Cash-flow squeeze / split payment → agree dates in writing; invoice the plan; do not rely on a verbal promise alone.

• Never got the invoice / wrong PO → resend PDF + correct PO; restart soft timing if genuinely not received.

• Silence / hostility → return to written formal demand; do not argue on the phone.

Follow every call with a short written confirmation.

Automate the calendar so awkwardness does not decide when you chase. Suggested defaults: pre-due at −3 days; due-day if unpaid; first overdue at +7 (B2B vs consumer template); formal demand at +14 (human review if the relationship is sensitive); stop immediately on payment; always attach PDF or payment link. InvoiceAdept Pro reminders can carry invoice number, amount and due date so you are not rewriting the same three sentences every Friday night. Use automation for the sequence; use the chase late payments guide when judgement and tone matter more than the clock.

Prevent late payment before stage 1 (no invented “X% more late payments” claims — just habits that reduce friction):

• Agree payment terms on the quote (14 days common for smaller trade jobs; 30 days for larger commercial work).

• Invoice on completion or stage completion, not “next week”.

• Take deposits (often 25–50% on jobs over ~£1,000).

• Offer bank transfer, card and a payment link on the invoice.

• Get CIS / VAT / reverse-charge status right on the PDF so purchase ledger does not hold the bill.

• Confirm remittance email and PO before you start.

• Quick Companies House check on new commercial clients for larger jobs.

This page owns the reminder calendar and templates. The sister chase page owns tone, channels and relationship-safe escalation after stage 4. Do not paste interest threats into stage 1. Do not stay forever on soft reminders when a commercial debt is a month late with no reply.

Worth pairing this with our guide to How to handle deposit payments tradesperson UK.

Worked example: £2,850 B2B invoice through the four stages

Assume: plumber invoices a limited-company facilities client £2,850 (incl. VAT) on 1 September, terms 14 days, due 15 September. Bank Rate reference for H2 2026 remains 3.75% → statutory 11.75%. Compensation band: £70 (debt between £1,000 and £9,999.99).

If the same invoice were to a homeowner, skip statutory interest language; use stages 1–2–3 (consumer wording)–4 without Late Payment Act claims, and rely on your contract and normal debt recovery routes.

Frequently asked questions

Can I charge interest on late invoices from day one?

For eligible B2B invoices, statutory interest runs from the day after the agreed payment date. If no date was agreed, GOV.UK’s late commercial payments guidance sets default periods (commonly 30 days for many commercial debts — confirm the exact rule for your situation on GOV.UK). Interest does not usually run while a genuine dispute is unresolved. Consumer jobs are different — do not assume the Late Payment Act applies.

How many reminders should I send before legal action?

There is no fixed legal minimum. Courts look favourably on businesses that made reasonable collection attempts. A practical pattern is the four stages above over roughly two to four weeks, then a formal Letter Before Action giving about 14 days to pay before considering a claim. Document everything.

Do I need a solicitor to send a Letter Before Action?

No. You can write and send it yourself. It should state the amount owed, reference the original invoice, set a deadline, and state your intention to issue court proceedings if unpaid. Templates and process sit on GOV.UK’s make a court claim for money guidance. Get advice if the debt is large, disputed, or cross-border.

What is the small claims limit in England and Wales in 2026?

The small claims track generally handles claims up to £10,000. You can start many money claims online via Money Claim Online; court fees scale with claim size (check current GOV.UK fee tables before filing). Scotland and Northern Ireland have different procedures.

Should I stop work if a previous invoice is unpaid?

Often yes — check your contract for suspension rights. If there is no written contract, you can still refuse further work until outstanding invoices are settled, but put the position in writing. Do not abandon a site unsafely; deal with welfare and building regulations sensibly while you pause commercial work.

Is statutory interest 12.5% or 11.75% right now?

While Bank Rate is 3.75%, statutory interest is 11.75% (3.75% + 8%). Older blogs (including earlier text on this URL) quoting 4.5% / 12.5% are out of date. Always check the Bank of England Bank Rate page and apply the OSBC six-month reference rule before you invoice interest.

Do payment reminders work for CIS subcontractors and main contractors?

Yes — the reminder sequence still applies. Add CIS-specific clarity on the invoice and in stage-2 replies (deduction status, verification, payment notices). Statutory late payment rights can still apply to commercial construction debts; reverse charge and CIS deductions are separate topics — see your CIS and reverse-charge guides so tax treatment does not become the excuse for non-payment.

If you want the four-stage calendar to run without Friday-night admin, InvoiceAdept helps you raise clean UK invoices (VAT, CIS and reverse charge where relevant), schedule Pro reminders for pre-due, due-day, +7 and +14, and keep a digital trail if you later need a formal demand or Letter Before Action. It does not replace GOV.UK process, Money Claim Online, or a solicitor when a debt turns contentious — it removes the friction that makes reminders late, vague or forgotten.
