We live in a 3 bedroom semi built in 2011. I have the original EPC / SAP. In 2013 we also added an orangery 3x4m to the rear. Now we're having a Supalite roof replacement including building regulations submission.
Once that is done - we want to remove the patio doors leading to the 'former orangery'. I've been advised that we need to complete a SAP and pay the council a fee. Is it possible to complete the SAP ourselves based on the original EPC and the Supalite U value information or is it way more complicated than this?
How much are council charging for a certificate? And how much does a SAP calculation cost if it isn't a DIY job!?
Thanks.
