Energy Performance Certificates (EPCs)
An Energy Performance Certificate (EPC) provides a detailed assessment of a building’s emissions and energy efficiency. It includes a rating from A (lowest emissions) to G, alongside recommendations for improvements to reduce emissions, energy consumption and running costs. EPCs are required when buildings are constructed, sold, or rented, ensuring transparency and promoting energy-conscious decisions.

EPCs are valid for 10 years, and are a legal requirement for all new, rented or sold buildings.

Benefits of EPCs include:

• Regulatory Compliance: EPCs are a legal requirement under the Energy Performance of Buildings Regulations.
• Cost Savings: recommendations in an EPC can help reduce energy bills by identifying cost-effective improvements.
• Reducing Environmental Impact: enhancing energy efficiency reduces carbon emissions, contributing to sustainability goals.
• Improving Marketability: Properties with better energy ratings are more attractive to buyers and tenants, increasing their market value.
• Informed Decision-Making for Enhanced Performance: EPCs provide actionable insights into a building’s energy performance and areas for improvement.

Arthian offers an Extended EPC service which meets the basic EPC requirements while combining an energy audit of the premises. Our experienced EPC assessors will have surveyed the whole building so an Extended EPC provides a report with appropriate and cost-effective detailed recommendations which can include building fabric, HVAC, lighting and renewables. Calculations will include emissions and energy savings as well as budget costings and accurate expected financial savings which allow payback on investment to be calculated.

Minimum Energy Efficiency Standards (MEES)
The Minimum Energy Efficiency Standards (MEES) legislation currently requires a rating of level E or better for non-domestic rented properties, this is confirmed by the EPC, and if the rating is below E then actions to take to improve the energy performance of the building can be implemented.

As part of our commitment to supporting landlords and property owners in navigating complex environmental legislation, our team provides expert guidance to ensure compliance with the Minimum Energy Efficiency Standards (MEES) regulations.

From 2027, non-domestic landlords will be required to meet a minimum Energy Performance Certificate (EPC) rating of C, with an even stricter target of B by 2030. These milestones represent a significant shift, making early action essential to safeguarding your investments and avoiding penalties or restrictions on letting properties.

Non-compliance with MEES could lead to financial penalties and reputational risks, as well as restrictions on letting properties that fail to meet the required standards.

With deadlines fast approaching, it is critical for landlords to:

• Proactively assess current EPC ratings
• Identify opportunities to improve ratings and enhance energy efficiency
• Develop a clear roadmap for meeting MEES milestones

At Arthian, we provide a comprehensive MEES service, and can support your organisation with the following:

• EPC Audits and Gap Analysis: We carry out detailed reviews of your properties’ EPC ratings and identify areas for improvement, providing a clear understanding of your current position in relation to upcoming MEES requirements
• Tailored Compliance Strategies: Our team develops actionable plans to help you achieve the required EPC ratings, balancing compliance with cost-effectiveness
• Project Identification and Support: We help you identify opportunities for energy-saving improvements and renewable energy integration, from insulation upgrades to HVAC system enhancements and beyond
• Ongoing Support and Monitoring: With regular reviews and updates, we ensure you remain on track as regulatory requirements evolve

Display Energy Certificates (DECs)
Display Energy Certificates (DECs) are designed for public buildings to demonstrate their actual energy usage over the course of a year. Unlike EPCs, which assess the theoretical efficiency of a building, DECs reflect real operational performance, and are applicable for public buildings such as offices, community centres, schools, hospitals, and leisure centres. A DEC is required if all the following apply:

• It is at least partially occupied by a public authority
• It has a total floor area of over 250m²
• It is visited by the public on a regular basis

The DEC shows the operational rating of the building and must be updated either annually (if floor area is in excess of 1,000 m²) or every 10 years (if floor areas is above 250m² and below 1,000m²). The rating is scored from an ‘A’ for very efficient through to a ‘G’ for inefficient. The DEC must also be made clearly visible to members of the public who use the building.

The benefits of DECs include:

• Transparency: DECs provide clear, accessible information about a building’s energy usage to the public.
• Operational Insights: Annual assessments help identify trends and areas where energy use can be reduced.
• Legal Compliance: Ensures adherence to regulations for public buildings, avoiding potential fines.
• Sustainability Leadership: Demonstrates a commitment to energy efficiency and environmental responsibility.
• Continual Improvement: Regular DECs encourage ongoing efforts to enhance energy performance year-on-year.

Arthian offers an Extended DEC service which meets the basic DEC requirements while combining a detailed energy audit of the premises. The Extended DEC provides a report with detailed recommendations, including budget costings and an accurate assessment of expected savings both financially and from energy conservation measures. This approach ensures that clients ensure that maximum benefit is gained from undertaking the DEC as well as being a useful reference for informing future energy efficiency planning.

Public buildings in Scotland require an EPC rather than a DEC.

TM44 Inspections
TM44 inspections are mandatory assessments for air conditioning systems with a cooling capacity over 12kW. These inspections are designed to evaluate the efficiency, performance, and environmental impact of air conditioning systems. A TM44 report provides recommendations to improve energy efficiency and ensure compliance with the Energy Performance of Buildings Directive.

The benefits of TM44 Inspections include:

• Energy Savings: Identifies inefficiencies in air conditioning systems, leading to reduced energy consumption and costs.
• Compliance: Ensures adherence to legal requirements, avoiding penalties.
• System Longevity: Regular inspections help identify issues early, extending the lifespan of air conditioning equipment.
• Environmental Benefits: Reducing energy usage minimises the carbon footprint of cooling systems.
• Improved Performance: Enhances the operational efficiency and reliability of air conditioning systems.
