We have made our service as efficient and user friendly as possible. By providing us with the building drawings and details requested on our online DEC data form, we provide you with your formal DEC fee proposal. All our DECs utilise approved software and are carried out by competent energy assessors defined under the National Occupational Standards. DECs are a visual representation (on a scale of A-G) and show the energy performance of the building in operation, based on actual energy consumption records, as recorded annually.
To find out more about the requirements of DECs please take a look at our informative reference page.
