How Moisture and Dampness Affect EPC Ratings?

Energy Performance Certificates (EPCs) measure a property’s energy efficiency, ranging from A (most efficient) to G (least efficient). One often-overlooked factor influencing EPC ratings is moisture and dampness within walls, floors, and roofs. Excess moisture can reduce thermal performance, increase heating requirements, and ultimately lower EPC

EPC Reporting Challenges in Hybrid Heating Systems

Energy Performance Certificates (EPCs) are essential for measuring a property’s energy efficiency, with ratings from A (most efficient) to G (least efficient). Properties with hybrid heating systems—combining traditional and renewable energy sources such as gas boilers with heat pumps—pose unique challenges for EPC reporting. Proper assessment

How Building Envelope Retrofits Improve EPC Ratings?

Energy Performance Certificates (EPCs) assess a property’s energy efficiency, ranging from A (most efficient) to G (least efficient). One of the most effective ways to improve EPC ratings is through building envelope retrofits—upgrading walls, roofs, floors, windows, and doors to reduce energy loss and enhance thermal

The Effect of High-Performance Glazing on EPC Assessments

Energy Performance Certificates (EPCs) assess a property’s energy efficiency, ranging from A (most efficient) to G (least efficient). One of the most impactful elements influencing EPC scores is glazing performance. Upgrading to high-performance windows and doors can significantly improve energy efficiency, reduce heat loss, and enhance

EPC Pitfalls in Properties with Multiple Extensions or Additions

Energy Performance Certificates (EPCs) assess a property’s energy efficiency, providing a rating from A (most efficient) to G (least efficient). Properties with multiple extensions or additions can pose unique challenges during EPC assessments, often resulting in lower-than-expected ratings if not carefully evaluated. Why Multiple Extensions Impact

The Role of Building Orientation in Maximizing EPC Scores

Energy Performance Certificates (EPCs) evaluate a property’s energy efficiency, with ratings ranging from A (most efficient) to G (least efficient). One often-overlooked factor influencing EPC scores is building orientation—the direction a property faces and how it captures natural light and heat. Proper orientation can enhance solar

How Thermal Mass in Walls and Floors Influences EPC Scores?

Energy Performance Certificates (EPCs) measure a property’s energy efficiency, taking into account insulation, heating systems, and the building’s thermal properties. One often-overlooked factor is thermal mass—the ability of walls and floors to absorb, store, and release heat. Properly utilized, thermal mass can stabilize indoor temperatures, reduce

EPC Strategies for Minimizing Heat Loss in Older Homes

Older homes often face challenges in maintaining energy efficiency due to outdated insulation, draughty windows, and inefficient heating systems. These factors can significantly impact Energy Performance Certificate (EPC) ratings, making it essential for homeowners to adopt strategies that minimize heat loss while improving energy efficiency. Common

EPC Assessment Challenges in Buildings with Mixed-Fuel Heating

Energy Performance Certificates (EPCs) evaluate a property’s energy efficiency, ranging from A (most efficient) to G (least efficient). While single-fuel heating systems are relatively straightforward to assess, properties with mixed-fuel heating systems—such as a combination of gas, electric, and renewable energy sources—pose unique challenges for EPC

How EPC Ratings Are Affected by Complex Roof Structures?

Energy Performance Certificates (EPCs) are designed to measure the energy efficiency of a property, ranging from A (most efficient) to G (least efficient). While insulation, heating systems, and windows are commonly highlighted factors, the structure and complexity of a property’s roof can also significantly influence EPC
