Frequently Asked Questions

Are there any hidden fees, registration fees or certification charges?+

No. We believe in transparent pricing, so there are no hidden fees.

The price you see for your course includes your training, learning materials, tutor support, assessment, internal quality assurance (IQA) and the cost of claiming your qualification certificate from the awarding organisation.

There are no separate registration fees, examination fees or certification charges added during your course.

Once you've qualified, you'll usually need to join a government-approved accreditation scheme before you can start producing Energy Performance Certificates (EPCs). The good news is that joining an accreditation scheme is free with almost all major schemes, although you'll be responsible for their ongoing membership or lodgement fees, which vary between providers. Many schemes also include additional benefits such as professional indemnity insurance, public liability insurance, software and technical support as part of their membership packages.

If a course includes any optional extras or third-party costs, these will always be clearly stated before you book, so you'll know exactly what is included with your course.

What if I fail an assignment?+

There's no need to worry. We don't expect every assignment to be perfect the first time.

If your assessor feels that an assignment needs further work, they'll provide clear, constructive feedback explaining what needs to be improved. You'll then have the opportunity to make the required changes and resubmit your work.

There is no limit on the number of resubmissions, so you can continue improving your assignments until they meet the required standard. Our goal is to help you understand the subject and successfully complete your qualification, not to catch you out.

Throughout the process, you'll have access to tutor support whenever you need it. If you're unsure about any feedback or need additional guidance, your tutor will be happy to explain what's required and help you move forward with confidence.

We believe learning should be supportive rather than stressful, which is why we work with you every step of the way until you've successfully completed your portfolio and achieved your qualification.

What happens after I purchase a course?+

Once you've booked your course, we'll guide you through every step of the process, making your learning journey as smooth and straightforward as possible.

Immediately after your purchase, you'll receive a confirmation email containing your booking details. Please check your inbox and your junk or spam folder, as confirmation emails can occasionally be filtered by your email provider.

The confirmation email will also contain a secure link to complete your enrolment. You'll be asked to upload any required documents so we can process your registration and prepare your course. Completing your enrolment as soon as possible helps us ensure everything is ready before your training begins.

If you've booked an online or self-study course, you'll also receive access to our Student Assessment Management System (SAMS), where you'll find your learning materials, assignments and course resources.

Before your course starts, we'll send you everything you need, including your course schedule, joining instructions and any preparation required. For online courses, you'll receive details of how to join your live training sessions. For classroom courses, we'll provide the venue information and everything you need for the day.

Once your training has been completed, you'll work through your assignments and portfolio. Your tutor will review each submission, provide feedback where necessary and sign off your work as you successfully complete each assessment.

After all of your assignments have been signed off, your portfolio is reviewed by our Internal Quality Assurer (IQA) as part of our quality assurance process. Once this has been completed, your qualification is claimed from the awarding organisation, and your certificate is typically issued within two weeks of the final sign-off.

After receiving your qualification, we'll guide you through the next steps, including joining an accreditation scheme, choosing any equipment you may need and preparing to start your career as a qualified Energy Assessor. Our support continues even after you've qualified, so you'll always have someone to turn to if you need advice or guidance.
