Health & Safety Calculators for UK Construction
Health and safety is a legal obligation on every UK construction site, and getting it right protects both your workforce and your business. Our calculators help you assess scaffold loading capacities, determine safe manual handling weights using the HSE's guidance, calculate daily noise exposure levels (LEP,d), and estimate PPE and safety equipment costs. These tools support the practical side of site safety management, helping you make informed decisions that keep your projects compliant and your workers safe.
UK construction health and safety is governed by the Health and Safety at Work etc. Act 1974, the CDM (Construction Design and Management) Regulations 2015, and numerous Approved Codes of Practice. The CDM Regulations require duty holders including clients, designers, principal contractors, and contractors to manage risks throughout a project's lifecycle. Our calculators reference key standards including the Work at Height Regulations 2005, the Control of Noise at Work Regulations 2005, the Manual Handling Operations Regulations 1992, and the Control of Substances Hazardous to Health Regulations 2002 (COSHH).
Use these tools to support your risk assessments, method statements (RAMS), and construction phase plans. They help quantify hazards, calculate safe working loads, and estimate the costs of proper safety measures - reinforcing that cutting corners on health and safety is never economically justified. The HSE issued over 5,000 enforcement notices to construction firms in recent years, making proactive compliance both a moral and financial imperative.
