SBEM Calculations and Commercial EPCs

We pride ourselves on providing a high-quality service at an affordable rate. We offer a quick turnaround to meet your demanding schedule. We use DesignBuilder, one of the leading SBEM software packages, to streamline the calculation process and reduce costs for our clients. Please get in touch for a friendly discussion about your project.

1. SBEM calculations and EPCs for new constructions

All newly constructed non-domestic buildings require SBEM (Simplified Building Energy Model) calculations and Energy Performance Certificates (EPCs) to demonstrate compliance with Part L of the Building Regulations (Approved Document L2).

Our accredited SBEM assessors can provide all the relevant SBEM documentation required to demonstrate compliance. If your project does not meet the design-stage target, we will provide recommendations to help achieve compliance with Part L2.

Our SBEM service for new-build projects includes:

"As Designed" SBEM calculations and compliance reports for Building Regulations submissions
Advice and recommendations to achieve a Part L2 pass
"As Built" SBEM calculations and compliance reports
Issuance of EPCs
Areas we cover: nationwide (any new constructions).

You will only need to provide us with a full set of constructions plans and specification (floor, elevation, section, site plans), we will take care of all other tasks involved in the SBEM calculations.

2. SBEM calculations for large commercial extensions

Where a proposed extension is more than 100 m² and exceeds 25% of the total useful floor area of the existing building, SBEM calculations will be required to demonstrate compliance with Part L. These large extensions are required to be designed and constructed to meet the more stringent new-build requirements.

In addition, certain extensions with excessive glazing, as well as conversion and renovation projects, may also require SBEM calculations.

Our SBEM service for large extensions includes:

"As Designed" SBEM calculations and compliance reports for Building Regulations submissions
Advice and recommendations to achieve a Part L2 pass
"As Built" SBEM calculations and compliance reports
Areas we cover: nationwide (any new constructions).

3. SBEM calculations for material change of use

Where a building undergoes a material change of use, for example, when it is converted into a shop, hotel, institution or public building, or when residential accommodation is introduced where there was previously none, the building will require significant thermal upgrades to demonstrate compliance.

Our SBEM service includes:

"As Designed" SBEM calculations and compliance reports for Building Regulations submissions
Advice and recommendations on thermal updates to achieve a Part L2 pass
"As Built" SBEM calculations and compliance reports

3. EPCs for existing commercial buildings

We also issue EPCs for existing commercial buildings. All commercial property for sale or let require a commercial EPC, which should be in place prior to marketing. We offer a reliable EPC service with quick turn-around time:

4. MEES (Minimum Energy Efficiency Standards) consultancy for existing commercial buildings

In accordance with the Energy Efficiency (Private Rented Property) (England and Wales) Regulations 2015 and the Private Rented Property Minimum Standard,

it will be unlawful to grant new leases of commercial properties with an EPC rating below an 'E' (EPC rating of “F” and “G”) from 1^st April 2018.
it will be unlawful to continue all existing commercial leases with an EPC rating below an 'E' from 1^st April 2023.

Buildings with an energy rating of “F” or “G” are defined by the Regulations as “sub-standard” buildings. Landlords, including private and public-sector (local authority) landlords, may need to improve the energy efficiency of these sub-standard buildings to achieve a minimum rating of “E” before they can be legally let, subject to applicable exemptions.

We can advise landlords on how to improve the energy ratings of their existing commercial buildings in a cost-effective way. Our consultants can undertake EPCs for all types of commercial buildings and provide guidance on how to achieve the minimum “E” rating. Our service is affordable, with a typical turnaround time of 3–5 working days. Please get in touch for a friendly discussion and some initial advice.

The areas we cover include Hertfordshire, Essex or other areas within 15 mile radius of our office.
