Industrial scaffolding in the UK is subject to a comprehensive framework of legislation, regulations, and guidance designed to protect workers and those in the vicinity of scaffolding structures.
The Work at Height Regulations 2005 form the primary legislative framework governing all work at height in the UK, including scaffolding. They require that work at height is properly planned, appropriately supervised, and carried out by competent persons. Scaffolding must be erected, altered, and dismantled only by those with the necessary skills and experience.
The Construction (Design and Management) Regulations 2015 (CDM 2015) require that scaffolding on construction projects is planned and managed as part of the overall construction phase health and safety plan. Principal contractors are responsible for ensuring scaffolding is fit for purpose and properly maintained throughout the project.
BS EN 12811 is the British and European standard that specifies performance requirements and design methods for access and working scaffolds, covering load capacity, structural stability, and safety features.
NASC (National Access and Scaffolding Confederation) guidance, particularly TG20, the technical guidance document for tube and fitting scaffolding, sets out best practice for the design and erection of compliant scaffolding structures in the UK. Many clients and principal contractors require NASC membership or TG20 compliance as a contractual condition.
SG4, the NASC guidance document on preventing falls in scaffolding operations, sets out safe methods of working during the erection, alteration, and dismantling of scaffolding, with a particular focus on managing the risk of falls at the leading edge. Adherence to SG4 is widely regarded as industry best practice and is increasingly referenced as a contractual requirement by principal contractors.
The Management of Health & Safety at Work Regulations 1999 also place important duties on employers in relation to scaffolding. They require that suitable risk assessments are carried out to identify hazards and determine appropriate controls, that competent persons are appointed to plan, erect, inspect, and supervise scaffolding work, and that workers receive adequate information, instruction, and training.
Underpinning these duties is the Schedule 1 “Principles of Prevention” — a hierarchy of control that requires risks to be avoided or combated at source where possible, and which prioritises collective protective measures (such as guardrails, exclusion zones, and crash decks) over individual protection such as personal fall arrest equipment.
Powertherm provides industrial scaffolding services across a wide range of sectors, with all operatives holding relevant CISRS (Construction Industry Scaffolders Record Scheme) cards and working in accordance with current NASC guidance and UK health and safety legislation.
