On 20th September the government launched a new Register for both Domestic and non Domestic EPCs now called the EPB Register
As well as a much needed update to the content of the EPC the other major change has been the removal of the .pdf version of the EPC. The EPC is now only available as an interactive, on-line document. Your Energy Assessor will now send you a link to the EPC rather than attach the document itself.
You can still request a printed copy to be sent to you. Alernatively you can print a copy from the new register itself.
