How Long Does an EPC Assessment Take in London?
If you are selling, renting or preparing to market a property, you may be wondering: how long does an EPC assessment take?
For most domestic properties, the assessment itself is relatively quick. The exact time depends on the size, type and layout of the property, as well as how easily the assessor can access the rooms and energy-related features.
At Urgent EPC, domestic EPC assessments are carried out across London and South London, with fast appointment options available for customers working to a tight property marketing deadline.
How Long Does an EPC Assessment Take?
A typical domestic EPC assessment can take around 20 to 45 minutes, depending on the property.
A smaller flat may take less time, while a larger house with several rooms, multiple floors or more complex features may require a longer inspection.
The assessor needs enough time to collect accurate information about the property before calculating its energy performance.
The assessment may include checks relating to:
Property dimensions
Heating and boiler systems
Windows and glazing
Insulation
Hot water systems
Lighting
Floors
Roof areas
Building construction
Energy-saving features
The more accessible the property is, the more straightforward the appointment is likely to be.
For a detailed explanation of what happens during an inspection, read our guide to what an EPC assessment checks.
How Long Does It Take to Get the EPC Certificate?
The assessment appointment and certificate delivery are two separate parts of the process.
First, an accredited assessor visits the property and records the information required for the EPC calculation.
The information is then processed to produce the property’s energy performance rating and certificate.
At Urgent EPC, fast and same-day services are available for customers who need their EPC quickly, subject to appointment availability.
The current service information states that many certificates can be delivered within around 2 hours after the inspection, helping customers who are working around a property sale or rental deadline.
If you need an EPC urgently, see our Same Day EPC service.
What Can Make an EPC Assessment Take Longer?
Not every property is the same.
Several factors can affect how long the inspection takes.
1. Property Size
A one-bedroom flat will usually require less inspection time than a five-bedroom house.
Larger properties have more rooms, dimensions and energy-related features for the assessor to record.
2. Number of Floors
Properties with multiple floors can take longer because the assessor needs to inspect the relevant areas throughout the building.
3. Property Layout
Extensions, converted spaces, HMOs and unusual layouts may require additional measurements or checks.
4. Access to Rooms
The assessor needs access to relevant areas of the property.
If rooms are locked or inaccessible, this can make the assessment more difficult and may affect the ability to collect complete information.
5. Heating and Hot Water Systems
The assessor may need to identify the type of heating and hot water systems installed.
Having useful information about recent installations available can make the process easier.
What Should You Do Before an EPC Assessment?
A little preparation can help your EPC appointment run smoothly.
Before the assessor arrives:
Make sure all rooms are accessible.
Unlock cupboards or areas containing relevant heating equipment where appropriate.
Keep boiler or heating documentation available if you have it.
Make sure loft access is available where applicable.
Tell the assessor about relevant extensions or improvements.
Keep information about insulation, glazing or heating upgrades available.
You do not normally need to carry out major changes simply because an EPC assessment is taking place.
The purpose of the visit is to assess the property’s existing characteristics accurately.
Do I Need an EPC Before Selling or Renting?
For most properties in England and Wales, an EPC needs to be commissioned before the property is marketed for sale or rent.
The official GOV.UK guidance explains the requirements for EPCs when selling or letting residential property. It also states that an EPC can generally be reused for ten years, provided it remains valid.
You can check the latest government guidance before arranging your assessment:
GOV.UK: Energy Performance Certificates for selling or renting a property
If you already have an EPC, it can also be worth checking whether your existing certificate is still valid before paying for a new assessment.

What If I Need an EPC Quickly?
Property transactions do not always follow a convenient timetable.
You may suddenly discover that:
Your EPC has expired.
An estate agent needs an EPC before marketing.
A rental property is ready for a new tenant.
Your property sale is moving faster than expected.
You need your property listing prepared urgently.
In these situations, a standard appointment may not fit your deadline.
