Quality Certificates

We are committed with quality

In 1998, we initiated our steps in the development and implementation of management systems in our organisation supported by internationally recognised regulations and, within our main policy of ongoing improvement, we have developed actions and taking of decisions with the objective of obtaining excellence in the management of our client oriented service.


Pioneer company in the UNE-EN 13816 certification of Transports

This commitment to client-oriented service is guaranteed by the management and each year we set objectives in this line that have allowed us to have a Complete Management System for quality (UNE-EN-ISO 9001), for environment (ISO 14001) and for occupational health and safety (OHSAS 18001) all certified by AENOR.

Due to this and aligned with our strategy we have taken another step forward to obtain certification of our service. Our quality management system is oriented to your satisfaction and in all the client-related processes, transparency of the information is guaranteed together with the resolution of discrepancies before formalising any contract.

Likewise, in the management system, studies are made to know the degree of satisfaction of our clients and their perception of the quality of our service and all possible reclamations are managed with the objective of improving the quality of our service.

In this sense, we have developed the project for certification of our Transport for Regular and General Use, in accordance to the UNE-EN 13816 standard by AENOR.

Our first ISO: ISO 9.001 QUALITY since 1998

For more than a decade, we have been working to implement the certification of our quality system by AENOR according to the ISO 9001 standard, with certification number ER 0891/2/01.

The first ISO with which CuadraBus starts its new road in which it will implement the processes of ongoing improvement that are the guarantee for clients and the company personnel.

Obtaining the Quality ISO meant a major improvement in our organisation when:

  • Standardising the activities of the personnel working in the company.
  • Increasing the satisfaction of companies and individuals that contract with us.
  • Measuring the execution of the processes.
  • Reducing re-processing.
  • Increasing our efficiency and reaching objectives.
  • Ongoing improvement of our services.
  • Reducing incidents during the service.

We are committed by our environment to obtaining the ENVIRONMENTAL MANAGEMENT ISO 14001 standard

At CuadraBus, we are aware and committed to working towards reducing the environmental impact of our activity and therefore we have an environmental management system certified by AENOR in accordance to the UNE-EN-ISO 14001 standard.

This allows us to work towards reducing this impact starting with a system that, summarising, allows us to:

  • Identificar y evaluar los aspectos ambientales relacionados con nuestra actividad. Nos permite conocer la magnitud y gravedad de los mismos y actuar en consecuencia.
  • Identificar y evaluar la legislación y normativa aplicable, relacionada con los aspectos ambientales y la propia actividad. Nos permite conocer el nivel de cumplimiento y nos obliga a actuar para ajustar nos a la legislación en todos los casos.
  • Concienciar y sensibilizar en materia ambiental a las personas que integran nuestra organización y las empresas que colaboran con CuadraBus (proveedores, subcontratistas, etc.).

Being aware that the sector is working towards the introduction of technological advances, incorporating cleaner technologies in the manufacturing of busses and coaches and in the operation of these reduced fuel consumptions and cleaner emissions. On an internal level, we have focussed our strategy on the improvement of oru environmental management in the following fields of action: criteria in the acquisition of vehicles, planning of the routes and trips, driving styles and habits, workshop and vehicle maintenance, waste management, etc.

OHSAS 18001 for PREVENTION since 2007

Occupational Health and Safety are key standards for any organisation. The implementation and application of an effective occupational health and safety management system helps us protect our company and our personnel.

A safer work place

This allows identifying dangers, preventing risks and establishing necessary control measures at the work place to avoid accidents. In addition to motivating safety of personnel, this will contribute to promoting involvement and efficiency.

Cost reduction

Less accidents, means reduced cost of inactivity for any organisation. In addition to improving the position of responsibility for the insurance.


Regular audits help us to continuously supervise our performance and improve our health and safety measures at our work places.

Our quality management system certified by AENOR

CuadraBus has a management system that integrates the fulfilment of all the mentioned standards and this has been certified by AENOR.
