Why that grade Two UK property-industry blogs; salary figures for employed assessors are more reliable than self-employed billing estimates. Course-seller index 3/10.
Figures are researched estimates, not guarantees. Check local rules before you trade.
Why anybody pays for this
Every UK property sale or rental legally requires a valid Energy Performance Certificate — this is structural, mandated demand, not discretionary spend, which makes it genuinely recession-resistant.
UK EPC certificate £35-£120 per property; employed assessors £28,000-£38,000/yr; self-employed can bill per-report and complete several properties/day.
Good fit if
Someone in the UK willing to invest weeks in accredited training for a steady, legally-mandated, recession-resistant niche most people don't know exists.
Skip it if
Anyone expecting a fast-start gig — this is a regulated, accreditation-gated profession with a genuine weeks-long training period before you can bill a single client.
What actually goes wrong
Accreditation compliance is the main requirement here — the real cost of getting this wrong is failing the accreditation exam or scheme audit, not a client-facing liability, since the assessment methodology is standardized.
This is a regulated, accreditation-gated profession, not a same-week side hustle — training takes weeks and there's an ongoing accreditation renewal cost.
Legally mandated demand provides a steady floor of work, but the training investment upfront is real.
