What Does an EPC Assessor Look for in Glasgow Properties?

Energy Performance Certificates (EPCs) are a vital component of the property market in the UK, providing valuable information on a property’s energy efficiency and environmental impact.

In Glasgow, Scotland’s largest city, EPC assessors play a crucial role in evaluating properties to determine their energy efficiency ratings.

But what exactly are they looking for when assessing Glasgow properties?


One of the primary aspects EPC assessors scrutinize is the insulation of the property. This includes checking the quality and thickness of insulation in the walls, roof, and floors. In Glasgow’s often chilly climate, effective insulation is essential for retaining heat and reducing energy consumption, thus improving the property’s energy efficiency rating.

Heating Systems

The heating system is a key factor in determining a property’s energy efficiency. Assessors will examine the type of heating system installed, whether it’s gas, electric, or renewable energy sources such as solar panels in Glasgow or heat pumps. They will also assess the age and efficiency of the boiler and radiators, as newer, more efficient systems can significantly impact a property’s EPC rating.

Windows and Doors

The quality of windows and doors can greatly affect a property’s energy efficiency. EPC assessors in Glasgow will inspect the type of glazing used, such as double or triple glazing, as well as the condition of seals and frames. Upgrading to energy-efficient windows and doors can enhance insulation and reduce heat loss, positively impacting the property’s EPC rating.

Air Leakage

Assessors will also check for any drafts or air leakage points in the property, such as gaps around windows and doors, as well as ventilation systems. Addressing these issues can improve energy efficiency by preventing heat loss and reducing the workload on heating systems, resulting in a higher EPC rating.


Energy-efficient lighting solutions, such as LED bulbs, are becoming increasingly popular in Glasgow properties. EPC assessors will assess the type of lighting fixtures installed and their energy consumption. Switching to LED lighting can not only reduce energy usage but also contribute to a higher EPC rating.

Renewable Energy Sources

Properties with renewable energy sources like solar panels or wind turbines typically score higher on EPC ratings. Assessors will evaluate the presence and efficiency of these renewable energy systems, as they contribute to reducing the property’s carbon footprint and energy costs.

Overall Energy Efficiency

Ultimately, EPC assessors in Glasgow consider the overall energy efficiency of the property. This involves assessing all aspects of the building’s construction, design, and systems to determine its energy performance. By identifying areas for improvement, property owners can take steps to enhance energy efficiency and achieve a better EPC rating.

In conclusion, EPC assessors in Glasgow focus on various aspects of properties to evaluate their energy efficiency and environmental impact. From insulation and heating systems to windows, doors, and renewable energy sources, every detail plays a crucial role in determining a property’s EPC rating.

By understanding what assessors look for, property owners can make informed decisions to improve energy efficiency, reduce costs, and contribute to a more sustainable future.
