Can I claim my CPD hours from your modules?+
Yes. Ozone Group Training is an accredited CPD provider, and our CPD courses are approved by The CPD Group and listed on the CPD Register.
On successful completion of a course, you'll receive a CPD Certificate of Completion showing the number of CPD hours awarded. You can use this certificate as evidence of your Continuing Professional Development (CPD) when maintaining your membership with your accreditation scheme or professional body.
Our CPD courses are designed to provide practical, up-to-date knowledge that helps Energy Assessors and other built environment professionals stay informed about industry changes, legislation and best practice.
As CPD requirements can vary between accreditation schemes and professional organisations, we recommend checking their current requirements. However, because our courses are accredited by The CPD Group and published on the CPD Register, you can be confident that you're completing recognised, high-quality CPD training.
If you're unsure whether a particular course is suitable for your CPD requirements, our team will be happy to advise you before you enrol.
