In addition, we also undertake Standard Assessment process (SAP), water efficiency assessments and Simplified Building Energy Models (SBEM), as per industry norms and regulations.

Why do I need an EPC?

It is a legal requirement to have a valid Energy Performance Certificate (EPC) when a building is sold, rented or constructed.

Your property's EPC needs to be available to potential buyers as soon as you start to market your property for sale or rent. This will inform people how energy efficient the property is, including any potential savings on fuel payments.
