Still sending your team to the same stale cert prep every year?

Honestly, your sysadmins deserve better than recycled slides and hypothetical scenarios. We run small-group programmes built around the fires they actually fight — monitoring meltdowns, patching chaos, capacity nightmares. Sixteen people per cohort, max. Real instructors who still carry pagers.

Four steps from enquiry to results

No bureaucratic procurement cycles. No twelve-page proposals. Here's what actually happens.

Fill out the quote form below — takes about ninety seconds. Tell us roughly how many people, which track interests you, and when you'd like to start. No commitment at this stage. We just need enough context to have a useful conversation.

We'll schedule a 30-minute call (or video, your choice) to understand your team's current pain points, tooling environment, and goals. We'll recommend a track and suggest any adjustments. If it's not a fit — and sometimes it genuinely isn't — we'll say so.

Your cohort starts on the agreed date. Sessions run weekly, live and instructor-led. Between sessions there's practical homework — real tasks using your own systems where possible. Our instructors are available between sessions for questions. No automated chatbot nonsense; actual human replies, usually within a few hours.

At the end of the programme, every participant completes a practical assessment. You'll also get a team-level report showing skill gaps closed, areas that still need work, and suggested next steps. We're not going to pretend six weeks fixes everything. But you'll have numbers to show your leadership team.

What we promise (and what we don't)

Max 16 per cohort

Small enough that every person gets air time. Large enough that group exercises actually work. We've tried bigger. It doesn't go well.

Working instructors

Every instructor still works in operations. Not "used to work in ops five years ago." Currently. They teach because they like it, not because they couldn't hack it in the field.

One free deferral

Life happens. Major incident, parental leave, sudden re-org — you can defer to the next cohort once at no extra charge. After that, there's a £200 re-enrolment fee.

Not government-accredited

Look, we'll be upfront: our programmes are not accredited by any government body. You won't get a nationally recognised certificate. What you will get is practical, applicable skill. If your procurement department requires accredited training specifically, we might not be the right fit.

Honest words from past participants

"We sent four people through the Strategic Overhaul track last autumn. Within three months our mean time to recovery dropped from about four hours to under ninety minutes. The disaster recovery module alone was worth the entire fee — we found gaps in our backup strategy we'd been ignoring for years. The instructor kept things practical and didn't waste time on slides."

Rachel Whitmore

Head of Infrastructure, Meridian Logistics

"Good programme overall. The homework assignments were genuinely useful and I'm still using the monitoring framework we built during the course. Knocking off one star because the scheduling was a bit rigid — we had a major outage one week and couldn't attend, and the recording quality wasn't great. They've said they're working on that."

David Okonkwo

Senior Systems Administrator, Helix Group

"Best training budget I've ever spent. My team finally speaks the same language about incident management."

Priya Sharma

IT Director, Caraway Partners

Questions we hear a lot

Logistics

Live, always. Every session is instructor-led with time for questions and group exercises. We record sessions so you can rewatch later, but the real value is in showing up and participating. Passive viewing doesn't build muscle memory.

We run cohorts in two windows: a UK/Europe morning slot (09:00–12:00 GMT) and an evening slot that works for the Americas (17:00–20:00 GMT). If you've got a team in Asia-Pacific and need something different, get in touch and we'll see what we can arrange.

Fair question. Recordings are available within 24 hours. If someone misses more than two sessions, we'll arrange a 1-to-1 catch-up with the instructor at no extra charge. We know ops people get pulled into emergencies — it's literally the subject matter.

Pricing & Cancellation

Yes. For five or more seats in the same cohort, we discount 10% off the per-seat price. For 11 or more, it's 15%. Mention your team size in the quote form and we'll include the discount in your estimate.

Cancel 14 or more days before your cohort starts and you get a full refund. Between 7 and 13 days, it's a 50% refund. After the first session, we can't offer a refund — but you can defer to the next cohort once at no charge. After that, there's a £200 re-enrolment fee. Full details are in our terms of service.

Absolutely. We issue invoices with 30-day payment terms for UK businesses. For international clients, we accept bank transfer in GBP, EUR, or USD. Mention your invoicing requirements in the quote form and we'll sort it.
