The Chartered Institute of Arbitrators (CIArb) has published an analysis of three significant Technology and Construction Court (TCC) decisions from 2025 regarding adjudication under the Housing Grants, Construction and Regeneration Act 1996. In Grove Construction v Bagshot Manor Ltd [2025] EWHC 591, the court clarified that contractors cannot adjudicate against assignees, confirming that an assignment does not transfer the burdens of a contract without a formal novation agreement. The Lapp Industries v First Formations Ltd [2025] EWHC 943 case examined whether multiple work orders should be treated as separate contracts or as variations of a single contract, the adjudicator’s decision to consider them as part of one contract was upheld and claims of a breach of natural justice were dismissed. In Midas Construction v Harmsworth Pension Funds Trustees Ltd [2025] EWHC 1122, the court addressed security for cost requirements when the claimant is insolvent, emphasising that security arrangements should leave the responding party in a position equivalent to that of dealing with a solvent claimant, and rejecting the claimant’s attempt to stage security payments. Collectively, these decisions provide clarity on jurisdiction, natural justice requirements, and security staging, and offer essential guidance for construction adjudications.
