EngTree
Become a Validator

Your chartership,
finally earning what it should.

EngTree pays chartered engineers (CEng / IEng / international equivalent) to verify the knowledge entries that anchor every channel on the platform. Tiered fees, AI-assisted workflow, CPD-grade audit trail, fully remote.

*“The validation work I'd been doing pro bono on LinkedIn for years now has a price tag and a paper trail.”* — Margaret Sinclair, CEng FICE

Four reasons chartered engineers
are signing up early.

Real fees, not pro-bono LinkedIn comments

You're already validating content informally — answering questions in DMs, reviewing graduate work, fielding standards queries. EngTree puts a paper trail and a price tag on the work.

AI Pre-Check does the heavy lifting

Claude Haiku reads each submission first — flags stale standards, weak math, jurisdictional mismatches, plausibility issues. You arrive with the questions pre-sorted. Average 30-40% time savings per entry.

Every validation is institutional-grade CPD evidence

Pro Tier auto-exports your validation activity to ICE / IET / IMechE / IStructE / CIBSE portals. Your CPD audit just happens. Saves the 4-8 hours of year-end log-padding most chartered engineers resent.

3-8 hours a week, fully remote

Validators set their own pace. Quarterly revalidation retainers on evergreen entries (£40 per entry per quarter) build the recurring revenue layer.

Fee structure

Three tiers.
Paid by chartership weight.

Tier-3 validation pays the most because the liability is real. Tier-1 work pays less but turns over faster. Most active validators split their week across Tiers 1 and 2; Tier-3 specialists (e.g. structural collapse, gas safety, fire engineering) command the premium.

Tier 1 — General best practice

£50

per validation

Career advice, soft-skill content, methodology overviews. Experience-based validation.

Example entries you might validate

  • How to prepare for the CEng review panel
  • What graduate engineers should expect in their first 12 months
  • Communicating engineering decisions to non-engineering stakeholders

Tier 2 — Technical guidance

£150

per validation

Design approaches, calculation methods, code-of-practice interpretation. Multi-validator review.

Example entries you might validate

  • Bored-pile design in London Clay — Eurocode 7 α-factor methods
  • BS 7671 earth-fault loop impedance calculations
  • Hydronic balancing fundamentals for commercial HVAC

Tier 3 — Safety-critical

£400

per validation

Gas, structural, electrical, fire, geotechnical bearing capacity. Chartership-required. Liability framework binds.

Example entries you might validate

  • Settlement-monitoring protocols for live infrastructure
  • Fire-engineering performance-based design judgements
  • Geotechnical bearing capacity for non-standard ground

Plus quarterly revalidation retainers (£40 per entry per quarter) on evergreen content you watch over. Active validator earnings: £2,400-3,200/month at maturity, before Pro Tier CPD reciprocity bonus.

The validator role
your chartership was made for.

We're bringing on the first 50 chartered validators ahead of public launch. Founding validators get priority queue, locked-in fee tier, and direct input on the AI Pre-Check evolution.
