Scaffolding & Access Calculators for UK Contractors

Safe access is fundamental to every construction project, and scaffolding remains the most common method of working at height in the UK. The Work at Height Regulations 2005 place a legal duty on employers to ensure scaffolding is properly designed, erected, and inspected. Our calculators help scaffolding contractors, site managers, and health and safety professionals plan scaffolding installations that comply with TG20:13 (the NASC's Technical Guidance for tube and fitting scaffolding) and BS EN 12811 standards.

Accurate quantity calculations are essential for profitable scaffolding contracts. These tools help you estimate the number of standards, ledgers, transoms, boards, ties, and fittings needed for common scaffold configurations. Tie pattern calculators ensure your scaffold is properly restrained to the building in accordance with TG20 requirements, which typically specify ties at maximum 4-metre horizontal and 4-metre vertical centres for a basic independent scaffold, though this varies with height and exposure.

Loading calculations are critical for scaffold safety. UK scaffolding is classified by duty — from Inspection duty (0.75 kN/m²) through Light duty (2.0 kN/m²) to Heavy duty (5.0 kN/m²) — and our calculators help verify that your scaffold design can safely support the intended loads. Whether you're pricing a domestic scaffolding job or planning access for a commercial project, these tools support the accurate planning that keeps workers safe and projects on budget.
