At Triangle, we believe that the quality of our work is matched by the strength of our credentials. Our business – and our people – hold a wide range of industry-recognised accreditations, certifications, memberships, and qualifications that demonstrate our commitment to safety, compliance, quality, and professional excellence.
From chartered status and safety standards to specialist sector certifications, these credentials aren’t just badges on the wall – they’re proof that we meet and exceed the rigorous requirements set by our industry and our clients. They also reflect the expertise, training, and professionalism of our team, giving our partners confidence in every project we deliver.
In 2023, Triangle received the coveted Solent University Award for Innovation at the New Forest Brilliance in Business Awards – an esteemed event that honours exceptional achievements within the local business community. This accolade reflects Triangle’s commitment to pioneering ideas and showcases their dedication to pushing the boundaries of creativity and excellence.
