Statute of Limitations for Account Stated / Open Account in United Kingdom

Overview

Run this scenario in DocketMath using the Statute Of Limitations calculator.

In the United Kingdom, a typical money claim framed as an “account stated” or “open account” is usually a limitation issue that falls under the Limitation Act 1980—most commonly s. 5 (a 6-year period).

That matters because UK debt disputes are often pleaded using familiar “labels”:

• Account stated: the parties are said to have agreed the balance.
• Open account: an ongoing running balance without a final agreement of the exact figure.

Even when the legal framing differs, limitation often comes down to the same practical questions:

• When did the cause of action accrue? (the “clock” starts at a specific point for each claim type)
• Was there any “acknowledgment” or “part payment” that changes the timing?
• Is there a scenario where a different or longer rule may apply? (e.g., certain deed or specialty situations)

To estimate the likely deadline, use DocketMath’s /tools/statute-of-limitations—helpful for getting a working date, but it doesn’t replace a lawyer’s review of the facts and the exact way the claim is pleaded.

Limitation period

For many UK money claims that are treated as contractual debt, the default limitation period is 6 years under Limitation Act 1980, s. 5.

1) Open account / running account: where the 6-year clock typically starts

An open account claim usually relates to money owed for transactions over time. In practice, courts may look at accrual based on how the claim is framed and how the balance was treated.

A practical way to think about it:

• If the claim is effectively about repayment of sums due under a contract, limitation commonly follows the 6-year contractual approach.
• The critical date is often the date when the money was payable and unpaid—for example, the last relevant unpaid sum becoming due—rather than the date of the first invoice.

2) Account stated: when the alleged agreement locks in the “balance”

For an account stated, you’re not only seeking payment of underlying invoices—you are alleging that the parties agreed the stated balance.

That “agreement” can be:

• express (e.g., a written confirmation),
• implied (based on conduct consistent with acceptance), or
• inferred from communications and relevant non-response patterns in the circumstances.

Limitation commonly runs from when the cause of action for the account stated accrues—typically the point at which the balance was agreed (or properly can be treated as agreed based on the evidence).

3) What you should collect to estimate the deadline (inputs)

To use DocketMath to estimate a limitation time-bar date, you typically need:

• A start/accrual date:

  • Open account: often the date the relevant unpaid balance item became due.
  • Account stated: often the date the stated balance was agreed (or when agreement can be inferred).
• Acknowledgments (letters/emails/messages admitting the debt) and/or
• Part payments (dates and amounts).

If there are multiple invoices and a running balance, you may need to decide which date best matches the way the claim is likely to be pleaded and how accrual would be argued. That selection is fact-specific, so treat the outcome as an estimate.

Key exceptions

A 6-year rule under Limitation Act 1980, s. 5 is a common starting point, but there are situations where the timing can change.

1) Acknowledgment or part payment can extend time

UK limitation law allows time to be extended where the debtor:

• acknowledges the debt in a relevant way, and/or
• makes a part payment toward the debt.

Operationally, a valid acknowledgment or part payment can effectively shift the practical limitation position—meaning the “clock” may move forward.

2) Different types of claims may use different limitation periods

Not every “debt” dispute is automatically a simple contract debt.

Depending on the facts, you may need a different limitation lens if the claim is based on:

• tort (wrongful acts rather than contract),
• statutory rights with their own limitation regime, or
• obligations arising under a deed (where different limitation treatment can apply).

This article focuses on account stated / open account, where the default assumption is often contractual—but it’s still important to confirm that the pleaded basis truly fits that category.

3) Other limitation mechanics can apply in special fact patterns

Some claims involve mechanics tied to later events (e.g., latent issues or discovery-type concepts). Those patterns are not the usual roadmap for straightforward “money owed” cases, but they can appear depending on the underlying transaction (for example, certain professional negligence or mis-selling contexts).

4) Substantive limitation vs procedural timing

Even where limitation is “substantive” (i.e., whether the claim is time-barred), litigation has procedural time elements. Court rules about how claims are brought and served can affect timing.

DocketMath’s tool is focused on substantive deadline estimation; it doesn’t address every court-specific procedural question.

Statute citation

The key UK limitation rule commonly relevant to contractual money claims is:

• Limitation Act 1980, s. 5 — typically 6 years for an action founded on simple contract (a common fit for many ordinary contractual payment obligations).

For account stated/open account disputes, the main fact question is often accrual:

• for open account, when the relevant sums became payable/unpaid,
• for account stated, when the balance was agreed (or can properly be treated as agreed).

The Limitation Act 1980 also contains provisions that address how acknowledgment and part payment can affect limitation timing.

Use the calculator

Use DocketMath’s /tools/statute-of-limitations to estimate a limitation time-bar date for a UK debt claim.

Because account stated and open account disputes can differ on accrual, the biggest input is choosing the correct “start date.”

Step 1: Choose the claim-type lens (open account vs account stated)

Select the approach that best matches the claim’s pleaded character:

• Open account / running account: use the date the relevant balance item became payable or the last unpaid sum became due.
• Account stated: use the date you can evidence the stated balance was agreed.

Step 2: Enter the accrual/start date

Enter the date that best matches the likely cause of action accrual:

• Open account: commonly the due date of the last unpaid amount.
• Account stated: commonly the date the balance was agreed (or when agreement can be inferred from communications/conduct).

Step 3: Add acknowledgments and part payments (if any)

If the debtor:

• sent an acknowledgment admitting the debt, and/or
• made a part payment,

enter the relevant date(s) in the calculator. The tool should adjust the estimate to reflect any extended time supported by those inputs.

Step 4: Review the output and interpret it

DocketMath will produce an estimated time-bar date based on:

• the default 6-year period (where applicable), and
• any extensions triggered by acknowledgment/part payment inputs.

Treat this as an estimate of the limitation boundary, not a guarantee. Evidence and pleading choices can change accrual and therefore affect the result.
