Season 2 is officially LIVE! First off, a massive thank you to everyone who tuned into Season 1. Honestly, the number of views and listens we had was overwhelming. We started this to help the industry, and seeing how many of you got stuck in was the best motivation to get back behind the mics.

In this kickoff episode, we aren't hanging about. We’re diving straight into the "why" behind the new Hands-On Installer Training Day happening on April 23rd.

We know the accredited courses often leave you hanging when it comes to the actual graft. That’s why we’ve teamed up—myself, Mike, Ollie (Zinc Electrical), Sam (Oval Renewables), and the legend that is Mark Allison (Apprentice 1-to-1)—to get people on actual roofs. No fluff, just real-world mounting, clamping zones, and navigating the nightmare that can be the ENA portal.

What we cover in this one:

• Where we’ve been (including some jet-setting to China).

• Why "sandwiches and solar" is the training combo you didn't know you needed.

• Getting hands-on with tile, slate, and Rosemary roofs.

• Mastering G98/G99 applications and SolarEdge design tools.

• A sneak peek at what’s coming this season (Longi Solar and the new Sigenergy Neo).

Whether you’re a sparky looking to get onto the roof for the first time or a seasoned installer wanting to sharpen your tech game, we’re here to help you succeed.

Join us every Wednesday at 7 PM.

We’re back at it again — this time live from the brand-new Apprentice 121 Training Centre, officially signed off by EAL and ready to deliver accredited solar, EV, and electrical training.

Join Mike, Dan, and the legend himself Mark Allison as we take a walk through the new setup — from the WECO battery wall and Solax rigs to the testing bays being built for 2391s.

We also chat with Dan “Sparky In Training”, Libby from Azzuri Electrical, and Mattie Allison, who’s stepping up to take the reins at PowerSonic while Mark focuses on the training side.

Plenty of laughs, cake, and real talk about the future of hands-on installer training in the UK.

👉 Listen in and find out what’s next for Apprentice 121.
