Strict quality procedures are followed for every trailer built and this is backed up with our ISO9001:2015 certification. Although we internally audit our systems and procedures to ensure our quality management system is working, we also invite BQAI an independent certification body to verify that we are in conformity to the ISO standard. We have an ongoing internal and external training programme for all staff to keep their knowledge and skills up to date, including regular external weld test inspections tested to EN25817 and suppliers providing ongoing in-house product training.


Here at Dennison Trailers we take the safety of our people and product very seriously, applying the latest principles of route cause analysis in establishing the immediate and underlying causes of accidents and near misses. The safety culture is very strong and driven personally by the Dennison family. It is our policy to conduct the business of manufacturing in such a manner that our activities minimise or eliminate any potential adverse effects on the environment through the use of integrated environmental management, procedures and planning.
