Regulatory, Legal and Contractual Frameworks
Regulatory, Legal and Contractual Frameworks
This domain tests the boundary between law and good practice: which duties are statutory, which are contractual, and how each is evidenced on a project.
Statutory layer
HASAWA 1974, EAWR 1989, MHSWR 1999, CDM 2015 and RIDDOR 2013 create the safety duties. Building Regulations Part P (England and Wales) makes notifiable electrical work in dwellings subject to building control or a registered competent person scheme. ESQCR 2002 governs the public supply and places duties on those working near network equipment. BS 7671 is not statute: it is the recognised standard of good practice used to demonstrate compliance with EAWR.
Contract layer
A contract needs offer, acceptance, consideration and intention. Common forms are JCT and NEC; NEC uses defined compensation events and early warnings. Payment and adjudication follow Part II of the Housing Grants, Construction and Regeneration Act 1996 as amended. Liquidated damages must be a genuine pre-estimate of loss. Variations should be instructed in writing and valued under the contract.
Worked example
A site manager instructs extra socket outlets verbally. Correct handling: carry out the work only if authorised under the contract, confirm the instruction in writing the same day, describe location, quantity and specification, and price it using contract rates or a quotation. The reasoning is that an undocumented verbal instruction is hard to value during the works and almost impossible to enforce at final account.
Traps
Describing BS 7671 as law; assuming Part P applies to commercial installations; ignoring contract amendments and order-of-precedence clauses; treating retention as a penalty.
