Non-domestic energy certification

Commercial EPC assessments

Establish the certification route for a non-domestic building and prepare the survey, evidence and lodgement scope.

A contemporary commercial building with landscaped public realm.

When you need this work

A commercial EPC records an asset rating based on a standardised assessment. The survey or as-built model still depends on accurate geometry, fabric and building-services information.

We first confirm the building type, trigger for certification and information available. New construction may build on an as-built Part L model. Existing buildings generally require an inspection and evidence review. Complex properties, mixed uses, incomplete services information or multiple tenancies may need additional preparation before an assessment can be completed. Lodgement is undertaken only within the appropriate accredited process.

What we check

Confirm the brief

We distinguish a new-build certificate, existing-building assessment and any separate advisory or compliance question. This avoids commissioning the wrong output.

Gather defensible evidence

Drawings, O&M information, equipment data, previous reports and access to the relevant spaces reduce reliance on conservative defaults.

Resolve complexity

Mixed-use areas, landlord and tenant systems, extensions and phased occupation can affect scope. We identify these issues before survey or modelling.

Common coordination issue

Confirm the unit being certified and access to its fixed services. Mixed uses, landlord systems and separate tenancies can change the scope; a previous certificate should not be assumed to describe the current building.

What you receive

Assessment

The appropriate non-domestic energy assessment for the agreed building and purpose.

EPC and recommendation output

Certificate and associated documentation where the assessment is complete and lodgement is included.

Evidence record

Key information used and material limitations encountered during the assessment.

Getting started

What we need

A contemporary commercial building with landscaped public realm.

Property information

Address, use, floor area, age, occupancy status and reason the certificate is required.

Drawings and records

Plans, sections, specifications, previous EPC or BRUKL reports and services documentation where available.

Access

Safe access to relevant internal spaces and plant, with a knowledgeable contact where an existing-building survey is required.

Before commissioning

Is a commercial EPC the same as an SBEM compliance report?

No. They are related in some new-build workflows, but a BRUKL compliance report and an EPC serve different purposes.

Can you assess a building without drawings?

Sometimes, but more surveying and conservative assumptions may be required. We confirm feasibility from the property details.

Does every commercial transaction need an EPC?

Requirements and exemptions depend on the circumstances. Obtain legal or property advice if you are unsure about the trigger.

Does every commercial building need to reach EPC B by 2031?

No. The government's June 2026 interim response proposes a targeted future rule for private rented non-domestic buildings over 1,000 m² in England and Wales, where cost-effective, and secondary legislation is still required.

Read the dated MEES update.

What affects the commercial EPC fee and turnaround?

Building size, location, assessment level, zoning, fixed-services complexity, drawing and evidence quality, site access and the purpose or deadline all affect the scope. We confirm the required survey, evidence and lodgement before quoting.

Sources and further reading

Use the edition, jurisdiction and assessment route that apply to the project. Publication of newer guidance does not automatically change an existing project’s requirements.
