What Is a BRUKL Report
A BRUKL report, short for Building Regulations UK Part L, is a mandatory energy compliance document required for new commercial buildings and major non-domestic refurbishments over 50m².
The report demonstrates that a building meets the UK Building Regulations requirements for conserving fuel and power, using calculations generated through SBEM, the Simplified Building Energy Model.
BRUKL reports are required at two key stages of a project:
- Design stage
- Post construction stage
Building Control uses these reports to confirm compliance before approving a development.
BRUKL reports also act as a precursor to the On Construction Energy Performance Certificate, making them a critical part of the commercial compliance process.
As Designed BRUKL Reports
What Is an As Designed BRUKL Report
An As Designed BRUKL report is produced during the design stage of a commercial building project. It models the theoretical energy performance of the building based on proposed designs and specifications.
These reports are commonly required before construction begins and must be completed by an accredited assessor authorised to produce non-domestic BRUKL reports.
What As Designed BRUKL Reports Are Based On
As Designed BRUKL calculations are created using:
- Proposed architectural drawings
- Mechanical and electrical services designs
- Specified construction materials and U values
- Lighting designs and control strategies
- Heating, cooling, ventilation, and hot water systems
- Assumptions about occupancy levels and operating hours
Although theoretical, As Designed BRUKL reports must be credible, realistic, and fully compliant with Part L, as they form the baseline for regulatory approval.
EPC-Hub works closely with developers, architects, and consultants to ensure assumptions are accurate and aligned with Building Control expectations.
As Built BRUKL Reports
What Is an As Built BRUKL Report
An As Built BRUKL report confirms the actual energy performance of a completed commercial building, based on what has been installed on site rather than what was originally specified.
This report is required at the end of construction and reflects:
- Final installed materials
- Actual mechanical and electrical systems
- Real lighting layouts and controls
- Updated occupancy and operational assumptions
Why As Built BRUKL Reports Matter
As Built BRUKL reports ensure:
- Compliance with Part L of the Building Regulations
- Alignment between design intent and construction reality
- Successful Building Control sign off
- A smooth transition to EPC registration
Any deviations from the original design must be accurately reflected, making professional assessment essential.
Our BRUKL Reporting Process
Step 1, Initial Consultation
We review your project scope, building type, and compliance requirements to confirm the correct BRUKL approach.
Step 2, Data Collection
We assess drawings, specifications, and site information depending on whether the report is As Designed or As Built.
Step 3, SBEM Modelling
Our accredited assessors run detailed SBEM calculations to model energy performance and emissions.
Step 4, Compliance Review
We ensure the report meets Part L requirements and addresses Building Control expectations.
Step 5, Report Delivery
You receive a clear, compliant BRUKL report ready for submission and approval.
Who Needs a BRUKL Report
BRUKL reports are required for a wide range of commercial developments, including:
- New non-domestic buildings
- Large commercial refurbishments
- Office developments
- Retail and shopping centres
- Warehouses and logistics facilities
- Hotels and leisure venues
- Healthcare and education buildings
- Public sector properties
To understand how BRUKL reporting fits into wider compliance, explore our guide to commercial EPC levels 3, 4, and 5.
BRUKL Reports & EPC Compliance
BRUKL reports play a key role in achieving a compliant commercial EPC. Errors or unrealistic assumptions at the BRUKL stage can lead to EPC challenges later.
We also support clients with MEES planning where required, helping buildings meet or exceed minimum energy efficiency standards.

Frequently Asked Questions About BRUKL Reports
Yes. BRUKL reports are required for new non-domestic buildings and major refurbishments over 50m² to demonstrate compliance with Part L.
As Designed reports model theoretical performance before construction. As Built reports confirm actual performance after completion.
BRUKL reports must be produced by an accredited assessor qualified to complete non-domestic energy modelling.
No. BRUKL reports demonstrate Building Regulations compliance. EPCs measure operational energy performance and are issued after construction.
