SBEM Calculation For Commercial Buildings

We can mobilise our qualified commercial energy assessors to undertake SBEM assessments on any type of commercial building across the UK. We can undertake new-build commercial SBEM assessments and provide design stage Part L2 SBEM calculations, and OCEPCs throughout the United Kingdom.

In response to the EPBD: as of 4th January, 2009 all commercial property for sale or let now needs a commercial EPC. The commercial EPC will tell you how energy efficient the commercial property is on a scale of A-G, with A being the most efficient. The certificate also tells you, on a scale of A-G, about the affect the property has on the environment.

It is now mandatory that a commercial EPC is in place prior to marketing a commercial property. Newly constructed commercial buildings are also required to have an EPC.

The commercial EPC is combined with a recommendation report on how the property’s energy efficiency can be improved, in addition to a potential rating if the recommendation work is carried out. Commercial EPCs are valid for a 10-year period.

Non-compliance with commercial EPC legislation will result in a penalty. The penalty is of up to 12.5% of the rate-able value of the property, with a minimum of £500 and a maximum of £5,000. This is in addition to the cost of a compliant commercial EPC.
