How long does an assessment take and how much does it cost?

The costs for preparing a commercial EPC depend on the type of building, the complexity of the building and the quality of the available information. A relatively modern building with updated layout drawings (plate plans) will be less expensive to assess than an older building with a similar layout for which no record drawings exist. The size of the building is also important, but a large warehouse is not immediately comparable with an office or retail store of comparable size. Due to the large variation in size and complexity of commercial buildings, the survey, modeling times and calculation times may vary.


The process of producing the information needed to perform the calculation is complex and time-consuming and the costs of producing an EPC for the simplest buildings with access to all parts of the property are close to several hundred pounds.
