The cost of a Commercial Energy Performance Certificate (EPC) in 2026 depends on several factors, including building size, complexity, type of property, and location. Unlike Domestic EPCs (which are generally straightforward), commercial surveys can vary widely in duration and detail — and that affects pricing.

What Influences Commercial EPC Pricing?
Commercial EPC assessors look at more than a domestic survey — they must evaluate multiple systems and building uses. Pricing can vary based on:
📌 Property size
Larger floor area = more inspection time
📌 Property complexity
Multiple HVAC, lighting, or specialist systems
📌 Accessibility
Hard‑to‑reach areas and multiple storeys take longer
📌 Building usage
Industrial, retail, leisure, and hospitality sites often need more detailed assessment
📌 Location
City centre inspections may cost more than outer‑London or suburban areas
What’s Included in the Cost?
A typical commercial EPC fee generally covers:
✔ On‑site energy inspection by a qualified assessor
✔ Data collection and assessment of:
Heating systems and controls
Ventilation and cooling
Insulation and thermal performance
Lighting systems
Hot water systems
Building layout and materials
✔ Government‑approved EPC software rating
✔ Upload to the official UK EPC Register
✔ Issued certificate (usually within 24 hours)
Commercial EPC vs Domestic EPC — Price Comparison
| EPC Type | Typical Starting Price | Typical Inspection Duration |
|---|---|---|
| Domestic EPC | From £34.99 | ~30–40 minutes |
| Commercial EPC | From £145 | ~45 min–3+ hours |
Commercial EPCs are more detailed, which is why they cost more.
