As part of our commitment to Quality Control, Abelian uses Quality Management systems to monitor the effectiveness of our cleaners and Account Managers. Our service delivery has enabled us to be awarded the ISO 9001:2015 accreditation for exceptional service standards.

Why do we monitor & track our services?

  1. Regular site visits occur allowing area manager’s to see a true reflection of our cleaners’ service delivery. Allowing us to determine if any additional training, or support is required, and provide where necessary to operatives.
  2. Using the traffic light system, ratings are given to all areas within the cleaning specification. Areas identified as red can be immediately raised and a reactive plan implemented. Areas that need no improvement are labeled green and continue to be monitored so standards do not slip.  
  3. Our auditing system enables key tasks to be performed when personnel are not on site i.e. ordering consumables. This way we ensure that our operatives always have the equipment, consumables & cleaning solutions required. 

Time & Attendance Systems (TAS) allows us to monitor and track the work patterns of our cleaning operatives. TAS records the shift patterns of every cleaning operative based on their time and location. This way Abelian remains 100% accountable for ensuring we deliver the agreed number of cleaning hours. This data can be made available upon request, creating transparency in our working relationship. 

Help Desk & Support Facility:  Abelian’s emergency contact and support desk gives our clients yet another platform in which they are able to contact and forward any concerns or positive reviews. All comments via this platform are managed by the operational team, via dedicated help desk personnel.

If clients prefer, we are also able to place a written comments book within their facility. Comments can be recorded and a comprehensive review will occur when the area manager visits a clients site. Any negative comments are handled via the operational management team and resolved accordingly. 

We use the Enhanced Disclosure and Barring service which enables us to make safer recruitment decisions – preventing us from allowing any unsuitable personnel working with vulnerable groups. As part of this commitment, all cleaning operatives must receive an enhanced DBS check prior to completing employment registration.

DBS checking allows us to determine the suitability of a cleaning operative. We provide all clients with Disclosure numbers and the names of any operative(s), which allows clients to view the suitability of each assigned operative. This method instils a trusted confidence in our safeguarding procedures. We also carry out List 99 searches whilst we wait for any DBS paperwork to be processed, acting as an interim security check should our client’s request.

All operatives are required to wear uniform; including tabards with the Abelian logo. This way our cleaning operatives are always professionally presented. ID badges are provided, matched with the Abelian uniform ensures the Abelian workforce is always easily identifiable. We know the benefit gained by our clients having well-presented cleaning operatives onsite – don’t forget, your cleaner represents an extension of your company.
