Civil vs Criminal Fraud Investigation: Key Differences Under UK Law 

What Is Fraud Under UK Law?

Fraud generally involves deliberate deception intended to gain a financial or personal advantage, or to cause loss to another person or organisation.

In England and Wales, many fraud offences fall under the Fraud Act 2006, which created several key offences including: 

• Fraud by false representation 
• Fraud by failing to disclose information 
• Fraud by abuse of position 

Fraud may be pursued as a criminal offence or as a civil claim, depending on the facts of the case and what the parties or authorities are seeking to achieve.

What Is a Criminal Fraud Investigation?

A criminal fraud investigation focuses on whether a criminal offence has been committed. 

These investigations are carried out by law enforcement or prosecuting authorities and may lead to criminal charges.

Who Investigates Criminal Fraud?

Several agencies may investigate suspected fraud offences, including: 

• Police forces 
• The Serious Fraud Office (SFO) 
• HM Revenue & Customs (HMRC) 
• The National Crime Agency 

The Serious Fraud Office generally deals with complex or high-value financial crime cases.

If prosecutors decide there is enough evidence and that prosecution is in the public interest, charges may be brought in the Magistrates’ Court or Crown Court.

Common Criminal Fraud Offences

Examples of criminal fraud offences include: 

• Investment fraud 
• Tax fraud 
• Mortgage fraud 
• Benefit fraud 
• Corporate fraud 
• Identity fraud 

A fraud conviction can lead to serious penalties, including substantial fines and custodial sentences.

Key Differences Between Civil and Criminal Fraud Investigations

Civil and criminal fraud cases can involve similar allegations of dishonesty, but the legal processes are different.

Burden of Proof

One of the most significant differences is the standard of proof required by the court. 

• Civil fraud cases are decided on the balance of probabilities. This means the court considers whether something is more likely than not. 
• Criminal fraud cases must be proven beyond reasonable doubt, which is a higher threshold.

The criminal threshold is therefore much higher. 

Who Brings the Case

• Civil fraud claims are usually brought by the person or organisation said to have suffered loss.
• Criminal fraud cases are prosecuted by authorities such as the Crown Prosecution Service.

Purpose of Proceedings

Civil proceedings usually focus on recovering losses, protecting assets, or stopping further wrongdoing.

Criminal proceedings focus on whether a criminal offence has been committed and whether punishment should follow.

Possible Outcomes

Civil proceedings may result in: 

• Compensation orders 
• Damages 
• Asset freezing orders 

Criminal proceedings may result in: 

• Imprisonment 
• Fines 
• Confiscation proceedings under the Proceeds of Crime Act 
• Criminal records 

In serious cases, fraud offences can lead to significant custodial sentences. 

Can Civil and Criminal Fraud Cases Run at the Same Time?

Yes. Civil and criminal fraud proceedings can sometimes run at the same time.

For example: 

• A victim may bring a civil claim to recover financial losses.
• Authorities may investigate whether criminal offences have been committed.

The two processes are separate, but evidence from one case may affect the other.

In some situations, a court may delay one set of proceedings if running both at the same time would create a risk of unfairness.

What Happens During a Fraud Investigation?

Fraud investigations are often lengthy and involve detailed analysis of financial evidence. 

A typical investigation may involve:

• Reviewing bank records and financial transactions
• Obtaining documents and digital evidence
• Interviewing witnesses
• Analysing business records
• Conducting interviews under caution

Authorities may also seek court orders to access documents or freeze assets during the investigation.

Because fraud cases can involve complex financial structures or international transactions, investigations may continue for months, and in some cases longer.
