QLS continues to achieve Safecontractor accreditation for 2017/18. This followed an assessment of our Health & Safety documentation to ensure that we comply with the Safecontractor Charter Standards.


QLS have successfully transitioned from ISO 9001:2008 to ISO 9001:2015, the updated certificate is available upon request.


QLS are one of the two companies that provide rework, inspection and retrofit activities for GM Ellesmere Port.

This was a fantastic effort by not only the management team but from the support we had, particularly from our colleagues at GM Luton where the good work during the Vivaro launch re enforced the abilities of our business to GM Europe’s management.

This good work has been reinforced by our team in Ellesmere Port led by Ray Jones with support from Tina Sweeting.


QLS has a 5000sqft facility available for storage, sub-assembly, rework and inspection in the North West of England.

Retro-Fits and Safety Campaigns

These campaigns have ranged from major engine component change to re flash activities (QLS have a number of our own CAN devices) through to minor fit and finish issues.
