Frequently Asked Questions
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.
Do you offer tutor support after the course?+
Yes. Supporting you doesn't end when your classroom or online training finishes.
Every learner receives ongoing tutor support while completing their portfolio and assignments. If you need help understanding a topic, using EPC software, collecting evidence or completing an assignment, our experienced tutors are available to guide you.
For learners on our Self-Study (Start Stop Learning) course, you can also arrange video or telephone sessions with a tutor whenever you need additional support.
Even after you've achieved your qualification, we're happy to answer general questions and offer guidance as you begin your career as a Domestic Energy Assessor. Whether you need advice about lodging your first EPC, choosing equipment or understanding the accreditation process, our team is always happy to help.
Our aim is not just to help you gain a qualification, but to give you the confidence and support to succeed in your new career.
What is the process from enrolling on the course to receiving my qualification?+
We've designed our training process to be straightforward and supportive, guiding you from enrolment through to becoming a qualified Energy Assessor.
First, you'll complete your chosen training course. This may be through Classroom Training, Online Live Training or Self-Study (Start Stop Learning), depending on the option you've selected.
After your training, you'll complete the required assignments and portfolio as part of your qualification. Your dedicated tutor will review each submission and provide feedback if any amendments are needed. Once an assignment meets the required standard, it will be signed off by your tutor.
When all of your assignments have been successfully completed and signed off, your portfolio is passed to our Internal Quality Assurer (IQA). The IQA carries out quality assurance checks to ensure your work meets the awarding body's requirements and that the assessment process has been completed correctly.
Once the IQA has completed the quality assurance process and your portfolio has been fully signed off, your qualification is claimed from the awarding organisation. Your certificate is typically issued within two weeks of the final sign-off.
Throughout the entire process, our tutors are available to support you, answer your questions and help you progress towards successfully achieving your qualification.
