Commercial window cleaning can involve glass at ground level, internal glazing, water-fed poles, ladders, mobile access equipment or specialist work at height. A commercial window cleaning risk assessment should explain the selected method, the hazards it controls and the arrangements that keep cleaners, building users and the public safe. It is not a generic form to sign and file; it must reflect the actual building and the actual job.
Why the building must be assessed first
Start with the windows and the surroundings. Record height, access, ledges, balconies, roof areas, fragile surfaces, overhead services, traffic, public footpaths and nearby entrances. Consider whether windows can be cleaned from the ground or internally before using a more complex method. Note who controls the building, how access is arranged and whether the work needs a permit, exclusion zone or coordination with other contractors.
Access equipment and work at height
The method statement should match the equipment. If a water-fed pole is suitable, explain reach, water management, storage and the area below. If a ladder, platform or other access system is proposed, cover inspection, set-up, stability, user competence and limitations. The HSE work at height guidance is an essential reference. Never use a method simply because it is familiar when the building makes another approach safer.
Practical commercial window cleaning risk assessment checklist
- Describe the window, building and surrounding hazards.
- Select the safest reasonably practicable access method.
- Check equipment, training and inspection requirements.
- Protect pedestrians, staff, vehicles and entrances below.
- Set weather limits and stop-work conditions.
- Record communication, first aid and rescue arrangements.
Protect people below and around the work
Public protection needs detail. Plan barriers, signs, spotters or timing where equipment, water or falling objects could affect people below. Keep emergency exits clear and agree how the building will be notified if an entrance changes. Wind, rain, ice, glare and visibility can change the risk, so state when the supervisor will stop work. A lone worker arrangement should not replace a suitable rescue plan.
Review weather, method and rescue arrangements
Review the assessment after an incident, near miss, change of equipment, change of building or new information from the site. The HSE work at height guidance should be read alongside the UK health and safety framework. The British Cleaning Council also provides useful industry context.

Questions about commercial window cleaning risk assessment
Who should write the risk assessment?
A competent person who understands the work and the site should prepare it, with client information and review from the responsible manager.
Can a risk assessment cover every building?
No. It can use a common framework, but the assessment must reflect the actual access, height, surroundings and equipment for the job.
When should window cleaning stop?
Stop when weather, equipment, access or public protection no longer meet the agreed safe method.
Final thoughts on commercial window cleaning risk assessment
A commercial window cleaning risk assessment should make the safest workable method clear. Survey the building, match equipment to the access, protect people below and set firm stop-work rules. Professional planning protects the team and the client.
Putting commercial window cleaning risk assessment into practice
Start with a site visit rather than a generic promise. Walk through the areas that people use, identify the surfaces and risks, and agree the times when work can happen without disrupting the business. A written scope should state what is included, what is periodic and what needs a separate specialist. It should also name the person who can approve access, report an issue and confirm that a corrective action is complete. This preparation gives the cleaning team a fair brief and gives the client a useful basis for checking the service. The HSE workplace guidance is a helpful reference when access, public movement or safe systems of work are involved.
What to agree before the first visit
Confirm opening hours, keys, alarms, lifts, water, power, storage, waste routes and the location of any sensitive equipment. Explain how staff, visitors, pupils, patients or customers move through the site, because the busiest route often needs a different frequency from a quiet room. Agree how spills, damage, low supplies and urgent requests are reported. A short induction is worthwhile: it helps cleaners understand the building and prevents the client from assuming that a task outside the scope will be handled automatically. If the plan changes, record the change and review its effect on time, equipment and staffing.
How to review the result
Review the first visits while the details are still fresh. Look at the agreed areas, the finished surfaces, the condition of equipment and the way the team communicates. If a task is missed, ask why before simply adding more hours. The cause may be restricted access, a change in occupancy, unsuitable equipment, an unclear instruction or a need for periodic work. Use a short inspection record with a location, date, standard, action owner and due date. Regular evidence-led reviews are more useful than waiting for a general complaint at the end of a contract.
A final check for site managers
Before signing off the plan, ask whether a new member of staff could understand it without a long verbal explanation. The tasks should be visible, the products and equipment should be safe, and the route for reporting a defect should be clear. Check that the schedule protects privacy, keeps routes open and leaves enough time for the expected result. When the building changes, update the scope rather than allowing small exceptions to become permanent gaps. Consistent service comes from clear expectations, competent people and inspections that lead to practical action.
