A financial risk assessment identifies events that could cause financial harm, estimates their cost and tests the controls in place. It explains the evidence behind each rating. Finance directors, insurers and solicitors can use that evidence to make decisions, plan improvements or scope further loss analysis. Estimated risk exposure must remain separate from a calculation of loss that has actually occurred.

What a Financial Risk Assessment Actually Delivers
A financial risk assessment isn't a generic heat map or a compliance spreadsheet completed once a year. It is a structured exercise that identifies uncertain events, estimates their financial consequences, tests existing controls and assigns responsibility for the remaining exposure.
A useful report should contain:
- Defined scope: The entities, processes, periods, transactions and risks covered.
- Calibrated scoring: Likelihood and impact scales linked to the organisation's actual financial position.
- Evidence-sourced entries: Each risk supported by records, interviews, testing or an explicit limitation.
- Residual ratings: The exposure remaining after controls are considered.
- Action ownership: Named owners, measurable actions, escalation thresholds and review dates.
The distinction between inherent and residual risk matters. A payment fraud risk may be material before approval controls are considered, but its residual rating should reflect whether those controls operate consistently. A weak assessment only records that a control exists. A defensible assessment tests whether the control prevented, detected or limited loss.
Practical rule: A risk rating should change when the evidence changes. If new bank records, access logs or reconciliation failures make no difference to the score, the scoring model isn't doing useful work.
The financial risk assessment report should also explain assumptions and limitations. That makes the output usable beyond the immediate exercise. A board can use it to allocate resources, an insurer can use it to understand loss prevention, and a solicitor can use the underlying analysis when preparing a claim or dispute.
A buyer or lender reviewing a business may also need a broader financial picture. Start with accounts, bank records, forecasts, material contracts and an explanation of key assumptions. Then test controls and quantify the exposures relevant to the decision.
The government's Fraud Strategy 2026 to 2029 estimates the economic and social cost of fraud in England and Wales at at least £14.4 billion in 2023–2024. That national estimate does not determine a particular firm's probability of loss. Each assessment still needs evidence about its own transactions, vulnerabilities and controls.
Scoping the Assessment and Identifying Risks
Scope determines whether the finished assessment can withstand challenge. Before anyone scores a risk, the engagement should state which entity, process, period, financial exposure and decision the work is intended to address.
The Fraud Prevention Savings Framework provides a sound discipline. It starts with a baseline, maps controls and weaknesses, estimates what would have happened without an intervention, and then assesses the effect attributable to the intervention. That sequence prevents management from claiming that every movement in losses resulted from a new control.
Start with records, not opinions
The initial request commonly includes:
- Financial records: Management accounts, general ledgers, budgets, cash-flow forecasts and bank statements.
- Control records: Reconciliation logs, payment approval evidence, supplier master files and access-rights reports.
- Loss records: Claims history, incident registers, recovery correspondence and prior internal audit reports.
- Operational records: Outsourcing agreements, dependency maps, service-level records and business interruption calculations.
Interviews should include the people who operate or challenge the controls. Credit controllers, IT and treasury leads, the money-laundering reporting officer and relevant budget holders often see different parts of the same exposure. The assessment should record what each person knows, what records support it and where accounts conflict.
Use a taxonomy that points to evidence
A structured taxonomy stops risk identification becoming a brainstorming exercise with no audit trail.
| Risk category | Typical question | Evidence source |
|---|---|---|
| Fraud | Could an employee, supplier or customer divert funds or falsify records? | Journals, bank data, supplier changes, access logs |
| Business interruption | Which process or dependency could stop revenue generation or increase cost? | Dependency maps, claims data, outage records, contracts |
| Compliance | Which legal or regulatory failure could create loss, remediation cost or reporting exposure? | Policies, regulatory records, contracts, training evidence |
The assessment should include financial loss, disruption, recovery cost, investigation cost and potential dispute cost where those items are relevant to the defined purpose. It shouldn't treat a risk as low just because no incident has yet been reported. Absence of detection may indicate an effective control, or it may indicate that nobody is looking.
Lighthouse's business risk assessment questionnaire can help organise information at the scoping stage. The engagement itself needs business-specific evidence and clear limits on what the records can establish.
Set boundaries explicitly
Subsidiaries, joint ventures and outsourced processes should be included or excluded by decision, not by accident. The scope should identify who owns the control, who holds the data, who bears the loss and whether a third party can obstruct testing. Where a group structure or outsourced process is material, the report should state whether the assessment covers the underlying activity, the contractual allocation of risk, or both.
Scoring Risks and Building the Risk Register
A financial risk assessment needs clearly defined scoring terms. A five-by-five matrix can help rank risks, provided the likelihood bands have a stated time horizon and the impact bands reflect the organisation's circumstances. Ordinal scores such as 1 to 5 are not probabilities and should not be multiplied by a cash amount to claim an expected monetary loss.
For a simple single-event model over a stated period, an illustrative calculation is:
Residual expected loss = event probability × mean loss if the event occurs × (1 minus the assumed proportional reduction from controls)
This model is a decision aid. The loss input should represent an estimated mean conditional loss, not the worst-case amount. Apply the control reduction only if it is supported and has not already been included in the probability or loss estimate. Repeated events, correlated risks and uncertain recoveries may require a more detailed model.
Hypothetical worked example
A hypothetical UK wholesaler considers a single invoice-fraud event over the next 12 months. For illustration only, it assumes:
- Event probability before controls: 30%
- Mean loss if the event occurs, before controls: £120,000
- Assumed proportional reduction from controls, applied once: 40%
The residual expected loss is:
30% × £120,000 × 60% = £21,600
The risk register should show the calculation, the evidence supporting each assumption and the resulting residual band. If the organisation's calibration places that amount in the medium band, the row might read as follows.
| Field | Value |
|---|---|
| Risk | Invoice fraud through altered supplier details |
| Process | Purchase-to-pay |
| 12-month probability before controls | 30% |
| Mean loss if the event occurs, before controls | £120,000 |
| Key controls | Supplier-change review, payment approval, bank-detail confirmation |
| Assumed proportional reduction from controls | 40% |
| Residual expected loss | £21,600 |
| Residual rating | Medium |
| Owner | Finance director or delegated procure-to-pay owner |
| Required action | Dual approval for payments over £25,000 |
| Review date | Set by the control owner and linked to evidence availability |
The £25,000 approval threshold is a hypothetical management control in this example, not a universal benchmark. The same register row can later support an insurance submission by showing the control environment and the potential loss, and it can feed a quantum schedule by separating actual transactions, avoided loss and estimated exposure.
Calibrate the rating
Historical incidence is useful but insufficient. A fraud that has never been detected may still have a high exposure if access is broad, supplier changes are poorly monitored and payment evidence is incomplete. Conversely, a recent near-miss shouldn't automatically inflate the rating without examining whether it represents a recurring weakness or a control that worked.
The assessment should retain:
- The source of the likelihood estimate.
- The basis for the impact range.
- The control test and sample limitations.
- The reason for the residual rating.
- The person who approved the rating.
The UK Finance Annual Fraud Report 2026 records £1,279.8 million in losses and 4,062,198 confirmed cases across authorised and unauthorised payment fraud in 2025. Unauthorised losses were £703.4 million across 3,814,128 cases; authorised push payment losses were £576.4 million across 248,070 cases. These distinct categories should not be conflated. National figures provide context, not a ready-made probability estimate for an individual firm.
Testing Controls Across Fraud, Interruption and Compliance
Control testing should answer a narrow question: what evidence demonstrates that the control operated, for the relevant population, during the relevant period? The answer differs by risk domain. A policy document may support design effectiveness, but it doesn't prove that staff followed the policy when money or service continuity was at stake.
| Risk Domain | Primary Test | Secondary Test | Evidence Required | Data Volume Needed | Likely Rating Impact |
|---|---|---|---|---|---|
| Fraud | Substantive journal and payment testing | Bank confirmations and system-log review | Journals, approvals, bank statements, supplier changes, access logs | Complete population where practical, or a documented risk-based sample | Failed approvals or unexplained changes can reduce the control rating materially |
| Business interruption | Dependency mapping and loss reconstruction | Claims-data reconciliation and contract review | Process maps, outage records, management accounts, claims files, supplier agreements | Records covering the interruption period and comparable operating periods | Unsupported downtime or revenue assumptions weaken the loss estimate |
| Compliance | Policy comparison and obligation mapping | Sample contract review and FCA register checks where relevant | Policies, training logs, reporting records, contracts, regulatory records | All material policies and targeted samples of transactions or contracts | Missing evidence may prevent an adequate rating even if the policy appears sound |
Fraud testing
For fraud, the strongest evidence often comes from matching transaction data to independent records. Journal entries can identify unusual users, timing or descriptions. Bank confirmations can test whether recorded movements occurred. System logs can show whether a user created, amended and approved the same payment.
When data isn't available, the report should say exactly what cannot be concluded. It shouldn't convert missing logs into an adequate control rating.
Interruption testing
Business interruption analysis needs a chain from the event to the financial effect. A dependency map identifies the affected process. Claims data, sales records, payroll, purchasing records and management accounts then test whether the claimed loss follows from that dependency. The calculation should distinguish lost contribution, saved costs, additional expenditure and any recovery.
Compliance testing
Compliance testing should compare policy with the obligations that apply to the firm and with operating evidence. The FCA's FG20/1 financial resources framework explains its expectations for relevant solo-regulated firms. It considers business risks, resources and the ability to meet liabilities, so the evidence file needs more than a balance-sheet snapshot.
Automated analytics can help identify unusual transactions, but outputs still need validation, a defined population and clear limitations. Lighthouse's internal audit checklist for fraud prevention can help turn the assessment into a repeatable control review.
The final report should record scope, population, sampling, missing records, contradictory evidence and the effect of each limitation. That documentation is what allows an insurer's loss adjuster or a litigator to understand what the conclusion does and doesn't establish.
Designing Mitigation Plans That Hold Up
A mitigation plan should be operational, not aspirational. Each material risk needs a named owner, a defined action, an investment range, a review cadence and a residual risk statement. “Improve controls” isn't an action. “Require independent confirmation of supplier bank changes and retain the confirmation with the payment record” is.
The four response choices are straightforward:
- Tolerate: Accept the residual exposure with documented authority.
- Treat: Add or improve controls that reduce likelihood or impact.
- Transfer: Use contractual allocation, insurance or another arrangement, while recognising that transfer rarely removes the underlying control duty.
- Terminate: Stop the activity that creates an unacceptable exposure.
Escalation should reflect urgency as well as amount. Suspected unauthorised payments may require immediate action to prevent further loss or seek recovery. Other exceptions can follow an agreed review timetable, depending on their consequences. Management should document thresholds and reporting obligations instead of relying on a universal monetary cutoff.
A control improvement is preferable to a policy change when the policy is sensible but execution is weak. A policy change is needed when the organisation has deliberately accepted an exposure that no longer fits its risk appetite. Neither response eliminates risk. The register should show the residual amount and the person authorised to accept it.
The governance file should retain:
- The approved risk register and scoring rationale.
- Control test results and exception logs.
- Management actions, owners and completion evidence.
- Board or committee decisions on accepted residual risk.
- Insurer notifications and relevant correspondence.
- FCA submissions or financial adequacy analysis where applicable.
A short explanation of the difference between an identified risk and an accepted residual risk is often more useful to directors than another colour-coded chart.
A Worked Example for an SME Facing Fraud and Interruption
The following is a hypothetical example. It illustrates method and evidence, not a client result.
A 65-person UK wholesaler discovers duplicate supplier records during a routine finance review. The duplicate records share similar bank details, and a dependent supplier has also reported an interruption that could affect deliveries. The finance director needs to know whether this is an isolated processing error, a fraud event, or a wider control failure.
Initial evidence and loss calculation
The review team preserves the journal entries, payment run, bank statements, supplier onboarding forms, confirmation emails and relevant system logs. The team also obtains delivery records, purchase orders, stock reports and management accounts for the interruption analysis.
The initial evidence identifies:
- Duplicate supplier creation without independent confirmation.
- Payment approval by a user with broader access than the policy permits.
- A gap between the supplier master-file change and the bank payment.
- Delivery dependence on one supplier for a material product line.
- No complete reconciliation between supplier amendments and payment exceptions.
To illustrate the calculation, suppose the wholesaler models a single event over the next 12 months using a 40% probability, a £400,000 mean loss if it occurs and a 26% proportional reduction from controls. The result is 40% × £400,000 × 74% = £118,400. These are invented teaching assumptions, not measured findings or a client result. Actual work would need evidence for each input and sensitivity testing. The amount is prospective risk exposure, not a proven theft or insurance claim.
The risk register row could state:
| Field | Hypothetical finding |
|---|---|
| Risk | Duplicate-supplier fraud and unauthorised payment |
| Exposure | £118,400 modelled 12-month expected loss under the stated illustrative assumptions |
| Control weakness | Supplier changes and payment approval weren't independently segregated |
| Interruption exposure | Dependent-supplier failure could delay fulfilment and create additional costs |
| Evidence | Journals, bank records, confirmations, logs, purchase orders, delivery records |
| Action | Freeze unverified changes, separate creation from approval, perform supplier confirmation and map alternative supply |
| Owner | Finance director, procurement lead and operations lead |
| Review trigger | Any payment exception, supplier-detail amendment or delivery failure above the agreed threshold |
Executive report wording
A concise executive report might use the following wording:
Illustrative finding: Duplicate supplier records and conflicting approval permissions warrant investigation. In this hypothetical example, the stated teaching assumptions produce a 12-month expected-loss estimate of £118,400. Actual loss, liability and recoverability have not been established. In a real report, the inputs and resulting conclusion must be supported by the working papers.
Control weakness: Supplier-bank-detail changes weren't consistently supported by independent confirmation, and user access permitted activity that should have been separated. The control design therefore didn't provide sufficient assurance that a changed supplier record represented a genuine and authorised instruction.
Recommended action: Management should suspend unverified supplier amendments, implement independent confirmation, restrict conflicting access rights, review the relevant payment population and document exception escalation. Operations should also assess alternative supply arrangements and retain evidence of any additional cost or lost contribution.
That wording doesn't accuse a person, promise recovery or imply that the report is legal representation. It distinguishes evidence, interpretation and recommended action.
Three uses for one evidence pack
The anomaly log, quantification working papers and mitigation plan can support three separate outputs.
Insurance claim: The commercial crime extension may require evidence of the event, the amount claimed, policy compliance, mitigation and recovery efforts. The evidence pack can be adapted for the insurer without changing the underlying calculations.
Recovery action: Supplier records, bank evidence, confirmations and system logs can help solicitors assess potential claims, tracing work and causation. A forensic accountant can quantify the financial effect, but legal advisers determine the appropriate cause of action.
Control remediation: The management plan can establish ownership, approval segregation, access restrictions and monitoring. The same records then provide a baseline for testing whether the intervention changed the loss rate, following the approach in the government's prevention savings framework cited earlier.
The important point is not that one report solves every problem. It is that disciplined evidence collection avoids three disconnected investigations producing inconsistent figures.
Reader Questions on Scope, Cost and Confidentiality
Finance directors, claims handlers and litigation counsel usually need commercial clarity before approving an engagement. The answers depend on the purpose, records and degree of challenge expected.
| Question | Short answer | Evidence typically requested |
|---|---|---|
| How is scope agreed? | A signed scoping letter should define entities, periods, questions, deliverables and exclusions. | Organisation chart, issue summary, policy wording, pleadings or regulatory request |
| Is pricing fixed or time-based? | Either structure may be appropriate. Fixed fees depend on a stable scope; time-based work suits changing facts. | Transaction population, record volume, expected interviews and deadlines |
| What increases cost? | Large or disorganised datasets, missing records, urgent deadlines, multiple entities, expert evidence and disputed assumptions. | Data inventory, system exports, prior reports and key correspondence |
| Who owns the data and working papers? | The client generally controls its records. The engagement letter should address working papers, retention and access. | Data-sharing schedule, retention requirements and instructions |
| Are findings privileged? | Not automatically. Legal privilege depends on the circumstances and legal advice structure, not simply the report title. | Instruction letter, engagement parties and legal-adviser involvement |
| How does FCA Principle 11 affect the work? | A regulated firm should consider whether matters need prompt, open communication with the FCA and should obtain legal or regulatory advice where appropriate. | Incident record, communications plan, regulatory status and reporting history |
| What happens if an incident is ongoing? | Preserve evidence, restrict further loss, separate fact-finding from unsupported conclusions and obtain appropriate legal advice. | Access logs, payment holds, preservation notices and incident chronology |
There isn't a universal engagement length or price. Scope, records, interviews, data extraction, independence requirements and whether the report may be tested in court all affect the cost. A short signed scoping letter protects everyone by confirming who instructed the work, who may rely on it, what questions are being answered and what the assessor hasn't been asked to do.
Third-party forensic input should have a documented UK GDPR lawful basis, appropriate data minimisation, access controls and retention arrangements. Personal data should be shared only to the extent necessary for the defined purpose, with responsibilities recorded between the parties.
Check which prudential rules and commencement dates apply to the particular firm. The document GC26/4 on COREPRU 7 is a June 2026 guidance consultation aimed at the cryptoasset regulatory framework. It should not be presented as final guidance applying to every FCA firm. Check for final guidance and the relevant rules before relying on it.
For relevant firms within scope, the Money Laundering Regulations require risk assessments under Regulations 18 and 18A, including proliferation-financing risk. The FCA Financial Crime Guide discusses customer, product, geographical and other risk factors that inform proportionate controls.
Organisations within scope of the corporate failure-to-prevent-fraud offence should consider fraud committed by associated persons with the intention of benefiting the organisation or, in relevant circumstances, its clients. This differs from assessing only fraud against the business. The government guidance on failure to prevent fraud explains the offence and reasonable prevention procedures, including risk assessment.
