Becoming a Pro-Fitter requires passing one of our courses and gaining your certification through our online assessment. There’s no better fenestration training out there. Our window fitter courses are specifically designed for installers, something you won’t find with standard carpentry courses or construction training.

We offer both online and practical fenestration courses for all skill levels, from novice to professional.

Online course durations range from 2 to 5 hours and are headed by our seasoned experts, providing the best platform for learning. We also offer an assessment at the end of each course that must be passed in order for you to receive your certification.

Practical course durations, range from 1-5 days and provide hands on tuition in a controlled environment. These courses, really do help mould you into a competent installer.

Upon successful completion of a Pro-Fitter course, you’ll have the skills to successfully and confidently install windows, doors and conservatory products. You’ll have also earned Pro-Fitter status, the gold standard for fenestration certification.
