Energy Compliance

TM44 Air Conditioning Inspections

If your building has air conditioning systems with a combined output over 12kW, you are legally required to undertake a TM44 inspection every five years. These inspections assess the efficiency of your systems and identify opportunities to reduce energy use and carbon emissions.
 
Arthian provides:

 
• Accredited TM44 inspections
• Portfolio-wide scheduling and compliance tracking
• Actionable reports with energy-saving recommendations

 
Our consultants ensure your systems are compliant and optimised for performance.

Energy Performance Certificates (EPCs)

An Energy Performance Certificate (EPC) is required when a building is constructed, sold, or let. It provides a theoretical energy efficiency rating from A (most efficient) to G (least efficient).
 
We offer:

 
• EPC assessments for commercial and public buildings
• EPCs are also essential for meeting MEES requirements and demonstrating energy performance to stakeholders.

Display Energy Certificates (DECs)

Display Energy Certificates (DECs) are required for public buildings over 250m² that are regularly accessed by the public. Unlike EPCs, DECs reflect actual energy usage over a 12-month period.
 
Arthian’s DEC services include:

 
• Standard and Extended DEC assessments
• Energy audits and improvement planning
• Multi-site DEC coordination and compliance tracking

 
We help public sector clients meet their obligations while using DECs as a tool for continual improvement.

Minimum Energy Efficiency Standards (MEES)

Under the MEES regulations, landlords must ensure that commercial properties meet a minimum EPC rating of E before they can be let. Non-compliance can result in financial penalties and restrictions on tenancy agreements.
 
Our MEES consultancy includes:

 
• EPC improvement planning and implementation
• Risk assessments across property portfolios
• Guidance on exemptions and enforcement

 
We help landlords protect asset value and maintain legal compliance.

Building Energy Compliance Assessments

Beyond individual certificates, Arthian offers full building energy compliance assessments to help organisations understand their obligations and identify opportunities for improvement.
 
These assessments include:

 
• Review of all applicable energy regulations
• Portfolio-wide compliance mapping
• Strategic recommendations for energy efficiency and cost savings

 
Ideal for facilities managers, estates teams, and sustainability leads, our assessments provide clarity and direction for long-term compliance.
