Types of Assessments

Energy assessments are crucial for evaluating a building’s energy efficiency and identifying areas for improvement. Various types of assessors specialise in different building structures. Explore the options below.

The Different Types

For Existing Domestic/Residential Buildings, Domestic Energy Assessors (DEAs) evaluate houses, flats, and bungalows, collecting on-site data to generate energy assessment reports using approved software.

Non-Domestic/Commercial Buildings are assessed by Non-Domestic Energy Assessors (NDEAs), including offices, shops, and similar structures. Their work entails on-site data collection. Higher-level NDEA qualifications are necessary for new-build and complex commercial buildings.

New Domestic Buildings are assessed by On-Construction Domestic Energy Assessors (OCDEAs) before and after construction, employing desk-based methods with building plans.

Public Buildings undergo energy assessments by Display Energy Certificate (DEC) Assessors, encompassing frequently visited places like churches and libraries. Their tasks involve on-site data collection and analysis, culminating in issuing an Energy Performance Certificate (EPC) using government-approved software.

Standard Assessment Procedure

The EPC calculation is based on the SAP, an approved methodology by the UK government. It considers various factors that impact a property’s energy performance, such as:

Construction

The type of walls, roof, floors, windows, and insulation in the property.

Heating & Hot Water

This is the type of system installed, fuel used, efficiency and controls.

Renewable Energy

Any renewable energy sources currently installed, such as solar panels.

Lighting

The type of lighting at the property and its energy efficiency.

Location

Geographic location of the home and the exposure to wind and sun.

Ventilation

Type of ventilation system at the home and its efficiency rating.

What’s An EPC?

An Energy Performance Certificate (EPC) is a legal document that assesses a building’s energy efficiency, mandatory for all properties being sold or rented. The rating ranges from A to G, with A indicating high efficiency and G indicating low efficiency. The EPC evaluates energy consumption for heating, cooling, and lighting, considering factors such as building type, size, insulation, and heating system. It also provides recommendations for enhancing energy efficiency.

Why Are They Important?

The EPC promotes energy efficiency awareness, assists buyers and tenants in making informed decisions, and helps reduce energy costs. Factors in the EPC calculation include building type, size, insulation levels, and heating system efficiency. Obtaining an EPC from a qualified energy assessor varies in cost based on building size and type.

Data Collection

Accredited energy assessors visit the property to gather data on these factors through:

  • Visual inspection
  • Measurements
  • Questionnaires
  • Reviewing existing documents (e.g., building plans)

Rating & Calculation

The assessor inputs the data into SAP software, which generates:

  • The property’s energy efficiency rating, ranging from A (most efficient) to G (least efficient).
  • An energy efficiency indicator (EEI), a numerical score reflecting energy performance.

The EPC document is then produced, featuring the rating, EEI, and improvement recommendations.

Apply Now

Validity

In the UK, EPCs are valid for 10 years.

After the EPC survey, your energy performance is evaluated, and an EPC Certificate is generated. Within 24-48 hours after the assessor’s visit, the certificate is uploaded to the government register and emailed to you. The certificate includes recommendations for enhancing your building’s EPC rating.
