Training & Certification · Format Guide · 2026
Here’s the answer most course providers won’t give you straight: for damp surveying certification, online and classroom lead to the same credential — the choice is genuinely about you, not the qualification. But for hands-on technician skills, the format isn’t a choice at all. Let’s take those in order, with the honest trade-offs of each.
The one structural rule before anything else
Diagnostic surveying certifies well online. Identifying damp types, interpreting moisture readings, building pathology, report writing — this is knowledge and judgement, and the FODCS Online certification and the FODCS Classroom course both earn the identical, independently City & Guilds Assured credential.
Hands-on installation doesn’t. Damp-proof course work, tanking, waterproofing — physical skills need physical practice, which is why the FODCT technician course is a one-day practical, in-person course, full stop. Anywhere offering to teach installation skills purely online is teaching you to watch someone else install things. So: if you’re heading for technician work, the format question answers itself — everything below is for the surveying decision.
FODCS Online vs Classroom, side by side
Exact prices for both routes — and what’s included in each fee — are published openly in our transparent training cost guide, and CITB funding may apply to either for eligible learners.
The honest question: which will you actually finish?
This is the variable that outweighs everything else, and the one course providers avoid mentioning. Online demands self-discipline. Self-paced means nobody chases you — and a course 40% finished earns exactly nothing. It suits people who’ve completed self-directed things before: if you know you follow through, the flexibility is a pure win; if your honest track record says otherwise, don’t buy flexibility you’ll waste. Classroom buys structure. Booked dates, a room, an instructor and a cohort make completion nearly automatic, and live questions suit people who learn by asking — you’re paying the premium partly for the accountability, and for many people that’s money well spent.
Or refuse to choose: the blended certification pathway combines self-paced online theory with classroom time — self-discipline for the reading, structure for the practice. It’s the answer for most people who email us genuinely torn.
Three profiles, three answers
The working tradesperson adding surveying to an existing business: online, almost every time. You can’t lose three days plus travel mid-season, the 15–20 hours fits into evenings, and you’re already comfortable working unsupervised. The career changer who wants confidence before charging clients: classroom or the blended pathway — live instruction and a cohort convert theory into confidence faster when the field is new to you. The complete beginner not yet sure this is the career: start smaller with the Level 1 beginner course online, confirm the interest is real, then pick your certification format with some knowledge behind the decision. And whichever profile is you, the format decision is only one of six checks worth running on any training — the full list is in our guide on how to choose damp proofing training.
