For many domestic Gas Safe engineers, stepping into commercial work can feel like a natural progression — but one that comes with a steep learning curve.

From more complex systems to stricter safety expectations, the transition requires more than experience alone. It requires the right training.

At CK Assessment & Training in Broxbourne, their Commercial Crossover Course is designed to bridge that gap — and according to one recent attendee, it does exactly that.

“It’s not just reading regulations — it’s applying them.”

Rakesh Patel, a Gas Safe engineer who recently completed the course, describes the experience as both practical and grounded in real-world application.

“Ian covers the regulations properly — not just reading them out, but showing how they actually apply on real commercial installs and servicing.”

Moving into commercial work introduces a number of technical challenges that aren’t always encountered in domestic settings.

Key areas covered included commercial pipe sizing, ventilation principles, purging procedures, testing sequences, commissioning processes and understanding safety classifications.

“It fills the gaps domestic engineers naturally have when stepping up.”

A defining feature of the course is its balance between theory and hands-on experience.

Workshops are designed to reflect real commercial environments, giving engineers the opportunity to engage with equipment and scenarios they are likely to encounter on-site.

“You’re not just sitting there — you actually get to try things.”

“If something doesn’t click first time, Ian will walk through it again until it does.”

Training is described as friendly, straight talking and geared toward working engineers, not classroom theory.

Additional support, including structured handouts and open Q&A sessions, allows learners to bring real job scenarios and gain practical guidance.

“The coffee is there — but let’s just say it’s more motivational than enjoyable.”

For Patel, the value of the course extended beyond certification.

“You leave with clearer commercial knowledge — not just a certificate.”

“I’ll be returning for more training and I’d happily recommend CKAT to other engineers.”

As demand grows for skilled engineers across both domestic and commercial sectors, the need for high-quality, practical training is more important than ever.

For those considering the move into commercial gas, the message is clear: get the right training — and make the step up properly.
