As of 2026, Commercial Energy Performance Certificates (EPCs) are a mandatory part of property transactions and lettings in the UK. Whether you’re selling, leasing, or refinancing a commercial building, understanding how much a Commercial EPC costs and what factors affect pricing is essential for budgeting and compliance.
This guide breaks down the typical costs of Commercial EPCs in 2026, the key elements that influence pricing, and tips for getting accurate quotes and value for money.
What Is a Commercial EPC?
A Commercial EPC evaluates the energy efficiency and environmental performance of non-domestic buildings — such as offices, shops, warehouses, hotels, and industrial facilities — and assigns a rating from A (most efficient) to G (least efficient).
The certificate includes:
Energy efficiency rating
Environmental impact (carbon emissions)
Recommendations for improvements
A valid certificate is required for sales, leases, and rentals of commercial properties. Professional assessments can be arranged via Commercial EPC services – EPCrate.
Typical Commercial EPC Costs in 2026
Commercial EPC costs vary based on several factors. Below are typical price ranges you can expect in 2026:
| Property Size / Type | Typical EPC Cost (GBP) |
|---|---|
| Small commercial units (e.g., small offices/shops) | £150 – £300 |
| Medium buildings (e.g., larger offices, mid-size retail) | £250 – £600 |
| Large or complex properties (warehouses, industrial, multi-zone) | £600+ |
These ranges are indicative and may vary depending on individual building characteristics and assessor rates.

Key Factors That Influence Commercial EPC Costs
Several elements affect the final cost of a Commercial EPC assessment:
1. Building Size and Floor Area
Larger buildings take longer to survey, increasing the cost. EPC assessors price based on the overall square meterage they need to inspect.
2. Complexity and Number of Zones
Multi-zone properties — where energy use varies across areas (e.g., separate floors or mixed uses) — often cost more because assessors must evaluate each zone individually.
3. Location
Assessors may charge higher rates in major cities or areas with higher business overheads (e.g., London and the South East) compared to rural locations.
4. Accessibility
Properties that are difficult to access or require special permissions (e.g., locked plant rooms, restricted areas) may take longer to assess and cost more.
5. Age and Construction Type
Older buildings with unusual layouts or construction may require more time to assess accurately, affecting the price.
6. Assessment Complexity
Buildings with multiple energy systems—such as advanced HVAC, renewable installations (solar PV), or industrial plant equipment—require more detailed evaluations.
What’s Included in a Commercial EPC Fee?
When you book a Commercial EPC assessment, the fee typically includes:
On-site inspection by a certified and accredited assessor
Assessment of building fabric, services, and energy systems
Calculation of energy and environmental ratings
Production of the official EPC certificate
Lodgement of the certificate on the UK Government EPC register
Optional services — such as detailed energy reports, improvement cost estimates, or follow-up consultations — may incur additional charges.

How Long Does a Commercial EPC Take?
Inspection times vary with building size and complexity:
Small commercial properties: 2–3 hours on site
Medium buildings: 3–5 hours
Large or complex facilities: Half-day to full-day assessments
The digital EPC certificate is usually issued within 1–5 working days after the inspection.
How to Get an Accurate Commercial EPC Quote
To receive a precise quote, you should prepare the following information:
Total floor area (m²)
Building type (office, retail, industrial, etc.)
Number of floors or zones
Existing energy systems and controls
Location and access details
Providing clear documentation and accurate details helps assessors give the most accurate price upfront and avoid unexpected fees.
Tips to Reduce Commercial EPC Costs
While compliance is mandatory, there are ways to keep costs reasonable:
1. Book Early
Avoid last-minute urgent bookings, which often carry a premium.
2. Organise Building Documentation
Supply floor plans, energy bills, and equipment details beforehand to reduce assessment time.
3. Provide Clear Access
Make all areas, plant rooms, and systems accessible to avoid delays or additional site time.
4. Consider Combined Assessments
If you manage multiple properties, some assessors offer bulk pricing or volume discounts.
FAQs: Commercial EPC Costs in 2026
Do EPC costs include VAT?
In most cases, fees are quoted inclusive of VAT — but confirm with your assessor.
Can costs vary by assessor?
Yes. Different certificated assessors may charge slightly different rates based on experience and overheads.
Are EPC reassessments cheaper?
If your building already has an EPC (still valid), reassessments are only needed when the certificate expires or after substantial energy upgrades.
Does improving my EPC reduce future costs?
Yes — energy performance improvements not only boost your rating but can reduce ongoing operational costs.
