How Long Does It Take to Get an EPC Certificate

Apr 14 2024

As a homeowner, it is essential to keep a check on your house’s efficiency and ratings. Having a cost-effective and environment-friendly house is everybody’s dream. But, you might wonder how you can keep track of your house efficiency ratings.

It’s simple! With an EPC Certificate.

An Energy Performance Certificate (EPC) is a crucial document providing insights into the energy efficiency of a property.

A common query among property owners is “How long does it take to get an EPC certificate?”

Let’s start with understanding the factors influencing the processing time of an EPC Certificate;

Factors Influencing EPC Processing Time

The processing time for obtaining an Energy Performance Certificate (EPC) is influenced by various factors. Understanding these factors is essential for property owners seeking to manage expectations and plan accordingly.

Here’s an exploration of the key elements that can impact the duration of the EPC certification process:

1. Complexity of the Property

Size and Type: Larger properties, such as estates or commercial buildings, often require more time for a comprehensive assessment compared to smaller residential units.

Energy Efficiency Features: Properties with advanced energy efficiency features, such as solar panels or complex HVAC systems, may necessitate a more detailed examination, contributing to an extended processing time.

2. Accessibility for Assessment

Availability of Access: The ease of access to all areas of the property is crucial for a thorough assessment. Limited access or restrictions can impede the assessor’s ability to evaluate certain aspects, potentially elongating the processing time.

Cooperation from Property Occupants: Property owners and occupants play a vital role. The willingness of occupants to allow assessors entry and provide necessary information can expedite the assessment.

3. Accredited Assessor Availability

Scheduling Challenges: The availability of accredited assessors can influence processing times. Scheduling challenges may arise, especially during peak periods when demand for assessments is higher.

Geographical Considerations: The geographical location of the property and the availability of assessors in that area can impact the scheduling and, consequently, the processing time.

4. Property-Specific Considerations

Commercial vs. Residential: Commercial properties often involve additional complexities due to their diverse nature. Residential properties generally have a shorter processing time but can vary based on specific characteristics.

Building Age: Older buildings might present unique challenges that require more thorough assessments, potentially extending processing times.

5. Urgency and Fast-Track Options

Expedited Services: Some EPC providers offer fast-track options for property owners with urgent requirements. While this can shorten the processing time, it may involve additional costs.

Availability of Fast-Track Services: The availability of fast-track services may depend on the EPC provider and the region.

6. Cooperation from Property Owners

Timely Information Submission: Property owners who promptly provide necessary information and documentation can contribute to a more efficient assessment process.

Preparation for Assessment: Adequate preparation by property owners, such as ensuring unobstructed access and making relevant documents available, can positively impact processing times.

7. Assessment Type

Level of Detail: The level of detail required for the assessment can influence processing times. A more detailed assessment, such as for a Display Energy Certificate (DEC) for public buildings, may take longer.

8. Post-Assessment Processing

Report Generation: The time taken to generate and finalize the EPC report after the assessment is completed contributes to the overall processing time.

9. Legislative Changes

Regulatory Updates: Changes in energy efficiency regulations or certification requirements can impact processing times as assessors may need to adapt to new standards.

Understanding these factors allows property owners to anticipate potential delays, communicate effectively with assessors, and plan for a smoother EPC certification process.

It’s time to head over to understanding How long does it takes to get an EPC Certificate;

Typical Turnaround Times for Residential and Commercial EPC Assessments

Understanding the typical turnaround times for Energy Performance Certificate (EPC) assessments is crucial for property owners seeking to calculate the duration of the certification process.

Here’s an explanation of the average processing times for both residential and commercial properties:

1. Residential Properties

a. Average Processing Time

General Timeframe: The average processing time for residential EPC assessments typically ranges from a few days to a couple of weeks.

Factors Influencing Time: Factors such as property size, type, and the complexity of energy efficiency features contribute to variations in processing times.

b. Property Characteristics:

Size and Type: Smaller residential properties may have a quicker assessment process than larger ones. The type of property, whether it’s a house, apartment, or other residential structure, also influences processing times.

Energy Efficiency Features: Homes with advanced energy-efficient features may require a more detailed assessment, potentially extending the processing time.

2. Commercial Properties

a. Distinct Considerations

Diverse Property Types: Commercial properties encompass a wide range of structures, from offices and retail spaces to industrial facilities. The diversity of property types contributes to varying assessment complexities.

Size and Complexity: Larger and more complex commercial properties often necessitate a more intricate assessment, leading to extended processing times.

b. Typical Processing Times

Varied Timelines: The processing times for commercial EPC assessments can vary significantly, ranging from a few weeks to several months.

Project-Specific Factors: Factors such as the scale of the commercial property, the intricacy of its energy systems, and the level of cooperation from stakeholders all play roles in determining the assessment timeline.

3. Considerations for Both Residential and Commercial Assessments:

a. Accredited Assessor Availability

Scheduling Challenges: The availability of accredited assessors may impact processing times. Scheduling challenges may arise, particularly during peak periods.

b. Preparation by Property Owners

Cooperation from Occupants: Timely completion of the assessment relies on the cooperation of property occupants. Property owners can expedite the process by ensuring access to all areas and providing necessary information.

c. Urgent Requirements

Fast-Track Options: Property owners with urgent EPC requirements may explore fast-track options, but availability and additional costs should be considered.


Overall, obtaining an EPC certificate involves various factors that collectively influence processing times.

Property owners are able to plan ahead, considering the complexity of their property and the accessibility for assessments. Hiring accredited assessors not only ensures accuracy but also contributes to timely EPC certifications.
