Lightbulb Law Briefing Note
The episode, distilled.
The brief
'Core term' is useful teaching language, but it can perform different jobs. In formation, the issue is whether the parties reached sufficiently certain agreement on essential matters. Under the Consumer Rights Act 2015, the statutory question is narrower: whether a term specifies the main subject matter or whether the challenge concerns the appropriateness of the price, and whether the term is transparent and prominent.
Formation: enough agreement to make a contract
The law asks objectively whether the parties intended to create legal relations and reached sufficient agreement on the matters necessary for their bargain. A contract need not always state every detail, but fatal uncertainty can prevent formation.
CRA 2015: not a blanket 'core term' immunity
Section 64 does not make every important term immune from review. The exclusion is limited to main subject matter and assessment of the appropriateness of the price compared with what is supplied, and it applies only where the term is transparent and prominent. Schedule 2 terms remain assessable.
Hidden price terms
A charge may relate to price yet still be assessable for fairness if it is not transparent and prominent. That is a better route than simply labelling the charge 'non-core'. The statutory analysis should be carried out directly.
Interpretation remains objective and contextual
Modern interpretation asks what the contractual language would convey to a reasonable person with the relevant background knowledge. Commercial common sense may assist, but the court does not rewrite a bad bargain merely because the result is unattractive.
The framework
Key points
Do not treat 'core terms' as one single technical category across all contract-law questions.
Formation asks whether agreement is sufficiently certain and complete in context.
CRA 2015 s.62 contains the fairness requirement; s.64 creates a limited exclusion for specified price/main-subject-matter assessments.
The s.64 exclusion depends on transparency and prominence.
Interpretation is objective and contextual; wording remains central.

Quick Check

Question 1
A consumer contract contains an important service term. Is it automatically exempt from fairness review because it is 'core'?
Question 2
A price-related surcharge is buried in dense small print. What is the best CRA 2015 approach?
Question 3
What is the safest statement about contractual interpretation?
Question 4
Which question belongs primarily to formation rather than the CRA fairness regime?
Your Lightbulb Law Moment
Notice what has just clicked.
The phrase 'core term' becomes much safer once you ask: core for what purpose? Formation, interpretation and consumer fairness may all involve important terms, but they do not use one interchangeable legal test.
Pause before moving on.
A gym contract advertises £50 per month but contains a prominent £150 joining fee and a hidden £200 high-usage surcharge. Which questions belong to price transparency, which to fairness, and which — if any — go to formation?

Accuracy note
The companion deliberately refines the source script. In particular, it distinguishes essential terms for formation from the narrower Consumer Rights Act 2015 s.64 price/main-subject-matter exclusion. Current law checked against CRA 2015 ss.62 and 64 and current Supreme Court interpretation authorities on 17 September 2026. Audio edit recommended before publication so the podcast mirrors this distinction.
