Energy Performance Certificates or EPCs are a compulsory requirement for all homes on the property market, this includes rental properties and, by law, a landlord is required to provide his tenants with an EPC when they move into the property in question. As of the 6th of April, new legislation require property owners to have an EPC in place within 7 days of marketing their property.

It’s not a terminator of people, but rather a terminator of rising energy costs. In the pre-1960s, the acquisition of retail, industrial or commercial air conditioning equipment involved a serious balance between expense and the practical relationship between the goods or services being delivered.
