What accreditations should a cleaning company have?

A successful contract cleaning company relies on its reputation as an efficient and effective service. One of the easiest ways to judge a cleaning service provider is by looking at their certifications and accreditations. These documents lend credibility and trustworthiness to businesses and act as surety of a professional job.

Contract cleaning companies that take time to apply for accreditation and additional training processes are more likely to be thorough and deliver on their promises. IWESCO is a leading contract cleaning service provider in South Africa. We offer commercial, industrial, specialised, events and once-off cleaning to businesses across the country.

In addition, we provide on-site waste control and other services too, including hygiene, garden maintenance and pest control. All of these services are underpinned by our certifications. When looking for the right cleaning service provider, what accreditations should they ideally possess?

ISO certifications are a must

The International Organisation for Standardisation (ISO) sets international standards and comprises representatives from the national standards organisations of member countries. ISO certification is a guarantee of world-class service in various fields. It demonstrates that a company is committed to quality, employee training, the environment and more. The following ISO standards are recommended:

  • ISO 9001 - This is the standardisation certification for quality management. ISO 9001 demonstrates a company’s commitment to quality and efficiency in the provision of services. IWESCO has ISO 9001 certification.

  • ISO 14001 - This is the certification for environmental management and shows that a business is committed to protecting the planet and minimising its environmental impact where possible. IWESCO holds ISO 14001 certification.

  • ISO 45001 - This is the certification for occupational health and safety. It means that the company implements a robust health and safety management system to protect employees and customers. While IWESCO does not hold ISO 45001 certification, we do implement a Hazard Analysis and Critical Control Point (HACCP) system for every job.

Additional accreditations to look out for

ISO certifications are proof that a company meets international standards, but they are not the only accreditations that matter. Contract cleaning companies should also implement local standardisation practices or be members of national associations. These will ensure that you are not hiring a fly-by-night cleaning service provider, but rather a highly professional and effective company.

In South Africa, members of the National Contract Cleaners Association (NCCA) are dedicated to developing high standards within the local sector. IWESCO is a member of the NCCA and this brings many benefits to the customer. Our professionalism, credibility and integrity are the results of strict adherence to the NCCA code of ethics and legislative requirements that govern the contract cleaning sector.

What’s more, your chosen cleaning service provider should also create a safety, health, environment and quality (SHEQ) file for each job. This file includes all the required documentation for international and governmental standards to be met. It is used like a checklist that enables us to tick off all the relevant schedules, reports, documents and registers that are needed for each job.

While all of the above certifications and accreditations are beneficial, a contract cleaning company does not have to have all of them. Depending on the scope of the job, you can narrow down the list to one or two accreditations and still receive a professional service at an affordable price. IWESCO maintains its certifications and memberships to ensure consistency and excellent customer service.
