This Practice Note looks at the adjudication procedures set out in standard form construction contracts and in common adjudication rules, such as the Scheme for Construction Contracts (the Scheme) and industry bodies. A table setting out the key issues dealt with by each is set out under Summary of the main differences between the contracts/rules below.

Where the Housing Grants, Construction and Regeneration Act 1996 (HGCRA 1996) applies, if a construction contract does not include compliant adjudication provisions (either setting out rules or incorporating them from eg the Scheme or a nominating body) then the rules in Part I of the Scheme will apply.

Construction contracts and professional terms of appointment commonly incorporate the adjudication rules set out in the Scheme (eg see clause 9.2 of the JCT Standard Building Contract 2016).
