What to Expect From Your
Commercial EPC Survey Pre-appointment, Site Survey, and Post

Here at Easy EPC we’re dedicated to keeping the “Easy” in “Easy EPC” and strive to make your experience with us as hassle-free as possible. For our Commercial EPC service this consists of 3 simple steps from your acceptance of our quote:

  • Booking - we’ll book you in and one of our assessors will arrange the appointment with the person providing access to the property.
  • Site Survey - the assessor will visit the property to survey.
  • Payment and Delivery - when the documents are ready we’ll invoice you and, once payment is received, email you your documents.

For more in depth info about what you can expect from Easy EPC’s Commercial EPC service please see below.


Once you’ve accepted our quote one of our friendly admin team will take some details such as property address, access contact details, and invoicing details as well as any extra information you may have such as details of lighting, HVAC or floor plans. They’ll use this information to book you in on our bespoke booking system. You’ll be sent a "Thank You for Booking" email which will include some helpful information about next steps, what other services we can help you with, and more. It will also confirm the survey type that you have booked in for, the survey property address, and price.

Within 24 hours one of our assessors will get in touch with the access contact via phone (or we can arrange via email, if required) to arrange a suitable appointment date for both parties. If you are a landlord or managing agent then we advise letting your tenant or access contact know that our assessor will be in contact to arrange an appointment for an EPC.

Once an appointment has been agreed you will be sent a "Confirmation of Booking Details" email, which contains important information that should be reviewed prior to the appointment, including:

  • Property address - as you would like it to appear on the EPC.
  • Survey type.
  • Appointment date and time - if a timeslot of arrival has been provided then two times will be shown.
  • Assessor name.
  • Price.
  • Call out fee information.
  • Next steps information.
  • Price information.
  • Instructions for how to get in contact if needed.

How to Prepare

If the property to be surveyed has any hidden insulation or renewables (such as solar PV or thermal, biomass boilers, air or ground source heat pumps*) then it is vital that we are informed prior to the survey date, failure to do so will result in them not being included on the EPC, which may affect the rating. We will require documentary evidence of the insulation or renewables being installed, please get in touch if this is something you need to provide.

* These are just examples of the most common renewables, there are many other types that we will also need to be informed about.

If you are a landlord or managing agent then we advise ensuring that the tenant will provide access to avoid call out fees, we also advise informing any staff or managers who will be present on the day that our assessor will be surveying to ensure that they are provided access.

Our assessor will need access to all areas of the property, including meter and boiler cupboards, so please ensure access to these is arranged prior to the appointment.


Commercial EPC surveys must be completed by an accredited SBEM assessor (also known as Non-Domestic Energy Assessors or NDEAs) who is qualified to the correct level. On booking we will ask you questions to determine what level of survey you need (Level 3, 4, or 5), here at Easy EPC we have assessors accredited to all levels so will be able to assist you no matter how complicated your property is.

The length of time that it will take our assessor to collect all of the necessary data highly depends on the size and complexity of the property, please ask on booking if you require a survey time estimate.

During the survey the assessor will be looking at the following elements while surveying:

  • How the property is constructed
  • Space heating systems
  • Water heating systems
  • Ventilation
  • Lighting
  • Any renewable technologies present

The commercial EPC survey is non-intrusive, meaning that the assessor will not be drilling holes or lifting floor boards to inspect what is below. Because of this, they will only be able to record any insulation or renewables that is visible to them on the day, which is why it is so important that we are informed of any hidden elements prior to the appointment (as noted in "How to Prepare").

During the survey they will be taking measurements, notes and photographs, and will make a basic floor plan to go with their notes to aid the processing of data post survey.


After the appointment the data needs to be processed at the desk using government approved software by either the assessor themselves, or for more complex buildings by one of our dedicated in-house energy calculation team. The processing of the data involves making a 3D computer model in a specialist software such as Design Builder or IES, the model is then loaded with additional data about the construction and services and the EPC rating is calculated by the government approved EPC software. This takes 3 - 4 working days.

Once the EPC has been completed it is then checked by our in-house quality assessor and, when approved, we’ll let you know that your documents are ready by emailing you the invoice (we also text you to make sure you know ASAP when it’s ready or so that you can let us know if you haven’t received our email for any reason). Please keep an eye on your spam or junk folder around the time that you’re expecting your EPC, as sometimes our invoice emails can get caught there.

You can pay over the phone with a debit or credit card or via bank transfer. When payment is received we email out the documents to yourself and, if requested, another email address of your choosing. Please note that it may take up to 24 working hours for payment to be received if you have paid via bank transfer.

If there are any queries after you’ve received your documents then we are always happy to help with these! Office hours are Mon - Fri 9:00 - 17:30 excluding Bank Holidays, but you can always email in out of office hours and we’ll get back to you as soon as we can.

If your property is rated less than an E rating (which is the minimum required rating for rental properties) then we will provide the EPC in draft format so that you have the option of lodging it to the national register. Please note that draft EPCs must be lodged within 6 months of the appointment date and you will need to get in touch with us to let us know if you want this done. We can also provide drafts first regardless of rating if asked, please let us know when booking if this is something that you would prefer.
