Pro-Fitter Training

NextGen Roof Systems Ltd are proud to be the North West of England Leka Roof Manufacturers. All Staff at NextGen are committed to providing a quality service and strive to ensure high standards of service are passed down through the channels. We aim to pass this kind of service onto our approved installers. Leka Systems have now become a partner with Profitter a fenestration training facility. Profitter provides some of the best training courses available and now has introduced a 2-day hands-on course based specifically on fitting the Leka System which we would recommend to all of our customers. Whilst the Profitter course is not compulsory, there are many advantages to taking part in the course including becoming a Platinum Leka Installer.

What is Pro-Fitter?

Tradespeople and businesses in the home improvement sector who fit and install glazing, windows, doors and conservatory products demonstrate a higher level of competence and know-how with Pro-Fitter fenestration certification. Becoming a Pro-Fitter requires passing one of our practical courses. These cover the fenestration installation process in its entirety, starting with onsite checks and ending with the overall assessment.
