Choosing a commercial window cleaning company involves more than comparing prices. For businesses, property managers, and facility operators, it is important to work with contractors that follow proper safety standards, carry the right insurance, and have suitable training for working at height.
Accreditations help show that a company takes health and safety seriously and follows recognised industry standards. They can also give clients more confidence when contractors are working on commercial buildings, public spaces, or high-level glazing.
This guide explains some of the most important accreditations and certifications businesses often look for when choosing a commercial window cleaning provider.
Why Accreditations Matter
Commercial window cleaning often involves working at height, using specialist access equipment, and operating around busy buildings. Because of this, safety and compliance play a major role in the industry. Accreditations help demonstrate that a company has been assessed against certain standards for:
- Health and safety procedures
- Staff training
- Risk management
- Insurance compliance
- Safe working practices
For commercial properties, these standards can help reduce risk while making contractor checks easier during procurement or site approval processes.
Health and Safety Certifications are Important
Health and safety are one of the biggest areas businesses should review when hiring a commercial window cleaning contractor. Companies working at height should have clear safety procedures in place before any work begins. Many businesses look for contractors with recognised health and safety accreditations or memberships that show they follow proper workplace standards.
This may include:
- SafeContractor
- CHAS
- Constructionline
- SMAS
These certifications are commonly used across commercial industries and can help show that the company has completed health and safety assessments.

IPAF And PASMA Training Matter for Access Work
Commercial window cleaning often requires access equipment such as cherry pickers, scissor lifts, and mobile towers. Contractors using this equipment should have proper operator training. Two of the most recognised training certifications include:
1. IPAF Training
IPAF certification relates to the safe use of powered access equipment, including mobile elevated work platforms. This training helps ensure operators understand how to use lifting equipment safely while working at height.
2. PASMA Training
PASMA training focuses on the safe assembly and use of mobile access towers. This is important for projects where scaffold towers or temporary elevated platforms are required during cleaning work. For buildings with difficult access conditions, experienced companies offering commercial window cleaning will usually have trained staff suitable for different access methods.
Check Insurance and Safety Cover
Accreditations are useful, but they should not be the only thing you check. A commercial window cleaning company should also have the right insurance in place, especially when working around people, vehicles, glass, and building exteriors.
Most businesses will want to see proof of public liability insurance, employer’s liability insurance, and cover for working at height. These help protect both the client and the contractor if damage, accidents, or access-related issues happen during the job.

Review Their Working at Height Process
Commercial window cleaning often involves elevated access, so safety planning should be clear from the start. A reliable company should explain how the work will be carried out, what equipment will be used, and how they will manage risks on site.
This usually includes risk assessments, method statements, equipment checks, staff training records, and emergency procedures. These documents show that the work has been planned properly before anyone starts cleaning at height.
Look At Similar Experience
Accreditations are important, but experience still matters. A company that has worked on similar commercial buildings will usually understand the access challenges, safety requirements, and scheduling issues that can come with the job.
This is especially useful for buildings with high-level glazing, busy entrances, restricted access, delicate surfaces, or areas open to the public. Contractors with wider specialist cleaning services experience may also be better prepared for more complex sites.
Key Takeaway
Commercial window cleaning companies should have the right combination of safety accreditations, access training, insurance cover, and practical experience.
Certifications such as SafeContractor, CHAS, IPAF, and PASMA can help show that a company follows recognised safety standards when working at height. Alongside these accreditations, businesses should also check insurance, training records, and experience with similar commercial properties.
