JCT’s own guidance describes each form’s intended use, and there’s no fixed financial limit for either. See the full JCT family.
When Minor Works is enough
- The work is simple and fully designed before tender.
- The period is short and there are no complex services installations.
- There’s no need for sections, named subcontractors or detailed control procedures.
When to choose Intermediate (or more)
- The project involves several trades and some complexity, but not enough for the Standard Building Contract or NEC.
- You want to name specialists, complete in sections or have more detailed provisions.
- Step up to the Standard Building Contract for larger or complex projects, or where bills of quantities are used.
For a homeowner, use JCT’s homeowner contracts instead: see homeowners and builders.
