The Legalities of Working at Height: What Every Facility Manager Must Check Before Hiring a Window Cleaner

Choosing a provider for your commercial window cleaning isn’t just a matter of finding a competitive rate. When you are arranging high-level maintenance across London and the South East, your single biggest exposure isn’t a missed pane of glass. It is a severe legal liability.

Under the UK’s Work at Height Regulations 2005, the responsibility for ensuring safety doesn’t just rest on the contractor you hire. If an accident occurs on your premises and it is discovered that you failed to properly vet the provider’s health and safety credentials, the Health and Safety Executive (HSE) can hold you and your organisation directly accountable.

With regulations tighter than ever, here is the definitive compliance checklist every facility manager must execute to ensure operational safety and protect their business from liability.

Signing off on a contract window cleaning agreement means looking at far more than the price tag. If you want to protect your building, your staff, and your own legal liability, you need to verify these four things before anyone touches your windows:

1. Site-Specific RAMS: This must be a custom safety blueprint written after a physical walk-through of your actual building, not a lazy, photocopied template.
2. Active Accreditations: Look for real, verified badges from recognised safety bodies such as CHAS, SafeContractor, or IRATA for any high-rise rope work.
3. Specialised Height Insurance: Double-check their paperwork to ensure their Public and Employer’s Liability explicitly covers your building’s exact roof height.
4. Direct Employment: Insist on a provider who uses their own trained, payroll staff so you never have unvetted, temporary subcontractors on your roof.

A major red flag during the procurement process is a contractor who hands you a generic, pre-printed Risk Assessment and Method Statement (RAMS).

Every commercial building has a unique architectural footprint. A legally compliant, robust RAMS must be generated following an on-site evaluation and must explicitly detail:

• How pedestrians and vehicles will be segregated from the work zone below.
• The exact machinery to be deployed, whether utilising truck-mounted cherry pickers/hydraulic platforms or setting up heavy-duty ground cords.
• Clear weather thresholds, such as strict wind speed limits, at which high-level operations will be safely aborted to protect workers and the public.

UK safety laws force businesses to follow a simple rule: if you can avoid working at height, you must. If you can’t avoid it, you have to do everything possible to prevent falls in the first place.

Matching your building’s architecture to the right commercial window cleaning setup doesn’t just keep you compliant, it stops you from overpaying for heavy machinery you don’t actually need:

• Water-Fed Reach & Wash Poles: The safest, most efficient option for low-to-mid-level glazing (up to 60 feet), keeping operatives safely on the ground and reducing setup time.
• Mobile Elevating Work Platforms (MEWPs): Utilising specialised cherry picker access methods for heights where poles cannot reach, requiring operators to hold valid IPAF licenses.
• Rope Access / Abseiling: For modern high-rise curtain walls, industrial structures, and iconic skyscrapers where ground access, traffic restrictions or narrow pavement footprints rule out heavy ground machinery.

Under UK standards, BS EN 795 and BS 8610, your safety eyebolts and structural roof anchor points must be professionally inspected, load-tested, and signed off at least once a year (or every six months if they are used for fall arrest).

Any professional window cleaner who values safety will flatly refuse to rig their lines to your roof until you show them a valid compliance certificate. Skipping this step or forcing a team to use uncertified anchor positions leaves your business open to immediate HSE prosecution.

Legally protecting your business means verifying that your external maintenance partner actively maintains gold-standard industry accreditations:

• CHAS & SafeContractor: Demonstrates that the company’s internal health, safety, and risk management systems are fully vetted, documented and benchmarked annually by independent safety bodies.
• IRATA (International Industrial Rope Access Trade Association): The absolute non-negotiable standard for abseiling window cleaning. Ensure the team leaders hold Level 3 safety supervision qualifications.
• Specialised Insurance Portfolios: Standard high-street business insurance is completely useless for high-level building maintenance. You need to ask for their paperwork and verify that their Public Liability explicitly covers working at your building’s exact height profile, with no sneaky, hidden height-limit exclusions.
