Risk Assessment for Cladding Installation

UK construction-safety guidance by the Riskora Editorial Team

Producing a proper risk assessment for cladding installation is not optional — it is a legal and practical requirement for construction work in the UK. Whether you are a sole trader or managing a multi-phase project, documented risk management protects your workers, satisfies clients, and keeps you on the right side of HSE enforcement.

When This Document Is Required

The Management of Health and Safety at Work Regulations 1999 require employers to carry out a suitable and sufficient risk assessment for cladding installation before operations start. Self-employed workers carrying out construction activities must also comply.

What Must Be Included

  • Scope and description of the cladding installation works
  • Site-specific hazards relevant to construction
  • Persons at risk (workers, public, visitors)
  • Existing controls in place
  • Risk rating before and after controls
  • Additional controls required
  • Residual risk level
  • Review schedule
  • Responsible person for review

Common Mistakes to Avoid

  • Using a generic template without adapting it to the actual cladding installation conditions on site
  • Not reviewing the document when site conditions change
  • Missing sign-off from a competent person before work begins
  • Under-rating risk to avoid implementing additional controls
  • Not consulting workers during the assessment process
  • Treating the document as a one-time exercise

Example Scenario

A construction contractor in UK needs to produce a risk assessment for cladding installation before starting work next week. The client has requested professional documentation as a condition of site access. Using Riskora, they select the relevant trade preset, review pre-populated hazards, adjust controls for their specific site, and generate a professional risk assessment in under 5 minutes — ready for review and sign-off.

The legal duty behind a risk assessment for cladding installation

The Work at Height Regulations 2005 govern the installation, with regulation 9 applying wherever the substrate is fragile. For buildings in scope of the Building Safety Act 2022, the golden thread of information means the assessment and method statement form part of the record for the building, and material and installation decisions must be traceable — which raises the standard of what is expected in writing.

Hazards and controls reviewers expect to see

Cladding sits at the intersection of two regimes that reviewers now check together: the work-at-height risk during installation, and the fire performance of what is being installed. Since the Building Safety Act 2022, documentation for a higher-risk building is read by people who will also ask what the product is and how the partially completed façade behaves in a fire — a question a generic work-at-height assessment does not answer.

HazardControl measure
Falls from mast climbers, MEWPs or the leading edge of the cladding lineMast climbing work platform or MEWP selected against the elevation and inspected before use, harness with restraint lanyard in every boom-type MEWP, and edge protection maintained at every unclad opening.
Wind catching panels during lifting and positioningStated stop-work wind speed for panel handling, panels never released from the lifting equipment until mechanically fixed, and vacuum lifters or purpose-made clamps rather than manual control of large sheets.
Falling panels, fixings and offcuts to the public or trades belowFull-height exclusion zone with barriers and marshals, netting or fans to the scaffold, tool tethering, and no work over an occupied entrance without a protected route.
Fragile surfaces and openings in the substrate during over-claddingAll rooflights and existing sheets treated as fragile, openings covered or barriered as soon as they are formed, and no reliance on the existing sheet to carry a person.
Hot works and combustible insulation during installationHot work permit with a 60-minute fire watch, combustible insulation kept in a controlled quantity at the working face, and the fire strategy for the partially completed façade agreed with the principal contractor.
Manual handling of long, awkward panels and railsMechanical lifting as the default with vacuum lifters for large panels, two-person handling only within assessed limits, and cut-to-size ordering to reduce site cutting and handling.

A defensible work sequence for cladding installation

  1. 1Survey the elevation and substrate, confirm fragile areas and openings, and agree the access method (mast climber, MEWP or scaffold) with the principal contractor.
  2. 2Install and inspect the access system; establish the full-height exclusion zone with barriers, marshals and protected entrance routes.
  3. 3Set out and fix the support rail system, maintaining edge protection at every unclad opening.
  4. 4Lift and place panels mechanically, never releasing the lifting equipment until each panel is mechanically fixed.
  5. 5Install insulation and cavity barriers in accordance with the fire strategy, keeping combustible material at the working face to the permitted quantity.
  6. 6Complete flashings, seals and detailing under hot work permit where flame is used, with a 60-minute fire watch.
  7. 7Progressive inspection and sign-off of each elevation, then strike the access system and hand over the installation records.

Why these documents get rejected

  • No stop-work wind speed for panel handling
  • Mast climber or MEWP named without inspection and rescue arrangements
  • Existing sheets and rooflights not treated as fragile during over-cladding
  • No fire strategy for the partially completed façade where combustible insulation is used
  • Exclusion zone described without marshals or protection to occupied entrances

Cladding Installation: common questions

What wind speed stops cladding installation?

Panel handling normally stops well below the MEWP limit because a large panel acts as a sail — many contractors set 17 mph for panel handling against a MEWP limit of around 28 mph. State the figure, who measures it and where it is recorded, rather than writing 'in high winds'.

Does the Building Safety Act change cladding documentation?

For higher-risk buildings, yes. The golden thread requires the information behind design and installation decisions to be recorded and kept, so the risk assessment and method statement become part of the building's record rather than a job-file document discarded at practical completion.

Who is responsible for the exclusion zone below cladding works?

The contractor doing the work, coordinated through the principal contractor. Because the zone usually affects the public or an occupied entrance, the assessment should name the barrier line, the marshals and the protected route rather than leaving it to be arranged on the day.
