Enhance Comfort: Bid farewell to cold spots and erratic temperatures, embracing consistent warmth throughout your home.

Reduce Carbon Footprint: Contribute to environmental sustainability by minimising energy usage and lowering your home’s emissions.

Access ECO4 Grants: Ensure eligibility for valuable government funding to offset the expenses of recommended energy-saving upgrades.

Types of Energy Assessments

Energy assessments play a vital role in evaluating a building’s energy efficiency and pinpointing areas for enhancement. Various types of energy assessors specialise in assessing different building structures. Take a look at the different types below.

The Different Types Explained:

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

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

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

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

The standard assessment procedure…

The EPC calculation relies on the SAP, a UK government-approved methodology, which takes into account several factors influencing a property’s energy performance. These factors include:


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.


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


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


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

What is an EPC?

An Energy Performance Certificate (EPC) is a legal document that assesses a building’s energy efficiency. It’s compulsory 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 the energy consumption for heating, cooling, and lighting the building. Factors like building type, size, insulation, and heating system are considered. Recommendations for enhancing energy efficiency are also provided.

Why is an EPC important?

The EPC serves several key purposes. It 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 via:

  • 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.


In the UK, EPCs remain valid for 10 years.

After the EPC survey, your energy performance is assessed, and an EPC Certificate is created. Within 24-48 hours of the assessor’s departure, the certificate is uploaded to the government register and emailed to you. The certificate provides recommendations for improving your building’s EPC rating.
