The Health and Safety Executive (HSE) has an open consultation (30 March - 24 May 2026) on updating the Control of Lead at Work Regulations 2002 (CLAW). SPAB, Icon (Institute of Conservation) and other organisations in the sector have been gathering evidence for responses. Below is a summary of our current position, adapted from our Winter 2025 and Spring 2026 magazines.
Leadwork limits
The proposed changes include broad-brushed exposure limits that are well-intentioned but could have substantial impacts on craft leadworkers and the conservation sector.
We wish to ensure safe working conditions for craftspeople, but our Technical and Research Committee is concerned that leadworkers operating ‘on site’, will find it exceptionally challenging, if not impossible, to satisfy the proposed requirements. Alongside industry colleagues, we seek to ensure that any changes to CLAW are proportionate, supported by appropriate evidence, and will protect but not unduly constrain leadworking practitioners working in building conservation.
A proportionate, risk-based framework would be far preferable than broad-brush controls. This would encourage reasonable, practical changes to reduce lead exposure while allowing practitioners to make informed decisions and not unduly constrain conservation work. It may not be possible to remove all risks from working with lead, but if less disruptive opportunities exist to create safer working environments, we feel that these should be exhausted before resorting to more limiting controls.
