Law vs rules vs guidance vs industry codes

A statute, regulator rule, ombudsman term of reference and industry code do not have the same legal status - but each can still matter.

Reviewed 8 September 2026General information

Law, regulator rules, guidance and industry codes can all matter, but they do not have the same legal status or effect.

A strong consumer complaint identifies what kind of source it is relying on. An Act or regulation creates law; regulator rules can bind authorised firms; guidance explains expected interpretation/practice; industry codes can evidence good practice or contractual commitments.

Calling every source “the law” weakens an otherwise good argument. The better approach is to state accurately why the source matters to the decision-maker.

Key points

  • Legislation and case law are legal authorities.
  • Regulator rules may be binding on regulated firms within scope.
  • Guidance may explain compliance but is not always itself a directly enforceable rule.
  • Industry codes can be highly relevant to fairness/good practice even where they are not statutes.
  • Ombudsmen may expressly consider good practice and guidance in addition to law.

A practical hierarchy

Legislation / case lawLegal obligations and interpretation.
Regulator rulesBinding requirements within the regulator’s rulebook/jurisdiction.
Regulator guidanceExpected approach; persuasive context for compliance.
Industry code / standardGood practice, data-sharing or sector standard; effect depends on scheme/contract/context.
Internal policyHow the organisation says it should operate; can be relevant to administration and fairness.

Why classification matters

PRAAD is important to credit reporting, but it is not a Consumer Credit Act section 87 default notice. The correct complaint can therefore rely on PRAAD as industry credit-reporting practice without pretending it creates a CCA statutory notice requirement.

Use the source for the right point

Quote the specific rule/principle that answers your issue. Avoid citing a long Act or code merely to make a complaint sound legal.

In practice

  • Label sources accurately in complaints.
  • Explain how the decision-maker is required or entitled to take the source into account.
  • Do not let an organisation answer one framework when your issue arises under another.

What to do

A practical next-step plan

  1. Identify the issue.
  2. Find the source that governs that issue.
  3. Classify the source.
  4. Explain its relevance and effect.
  5. Check version/effective date.

Common traps

Things that often confuse the issue

  • Calling guidance legislation.
  • Treating an internal policy as if Parliament enacted it.
  • Citing the wrong framework because it uses similar terminology.
