Commercial EPCs

Partnering with Commercial EPC Assessors to Improve Building Ratings

In today’s energy-conscious environment, achieving higher EPC ratings is a priority for building owners, tenants, and consultants. Powrmatic works closely with non-domestic (commercial) EPC assessors to help identify and implement HVAC strategies that significantly improve a building’s energy performance certificate (EPC) outcome. With HVAC systems contributing approximately 40% to 70% of a commercial EPC assessment, the right upgrades and improvements can make all the difference.

Smart Upgrade Strategies

We evaluate existing systems and highlight quick-win improvements — from controls and destratification fans to ventilation upgrades — that offer maximum EPC impact for minimal cost.

Tailored Proposals

We develop bespoke upgrade plans based on each building’s layout, usage, and EPC goals — balancing performance improvement with cost-effectiveness and practicality.

CO₂ Reduction Focus

Every recommendation we make is designed to cut carbon — directly improving modelled emissions and helping your clients achieve better EPC grades.

Quick Wins That Make a Real Difference

Powrmatic helps identify practical, budget-conscious upgrades that have a high impact on EPC ratings, including:

Destratification fans to reduce heat loss in large spaces

Air curtains to minimise infiltration

Smart controls and zoning systems

Ventilation upgrades to meet modern standards

High-efficiency electric, hybrid and heat pump systems

These measures not only help improve EPC outcomes but also reduce operating costs and carbon emissions.

Why it Matters

In non-domestic EPC assessments, HVAC systems typically account for 40% to 70% of the total rating. In larger or more complex buildings, inefficiencies in heating, cooling, and ventilation are magnified — often dragging down performance. Since both SBEM and DSM models heavily weight HVAC performance, even modest improvements can significantly boost EPC grades. Powrmatic understands these dynamics and brings decades of commercial HVAC expertise to help assessors and their clients make smart, impactful upgrades.
