Dear Sir/Madam
NEW GREEN DEAL MEASURES
NOTICE OF APPROVAL FOR CALCULATION METHODOLOGIES
I am writing first to inform you that the Department of Energy and Climate Change (DECC) has confirmed some additional measures that will be introduced into the Green Deal, and to clarify where such measures are notifiable building work under the Building Regulations and whether there are competent person scheme installers who may in some cases self-certify the work where it is notifiable.

I am also writing to inform you that we have issued a new notice of approval for the calculation methodologies for CO 2 emissions, fabric energy efficiency and energy performance certificates for new buildings.
Scope of this Circular Letter
This Circular Letter applies to local authorities in England carrying out building control functions. It also applies to local authorities in Wales carrying out building control functions in respect of excepted energy buildings1.

Notice of approval of methodologies of the calculation of the energy performance of buildings
Regulations 25, 26, 26A, 27, 27A and 29 of the Building Regulations 2010 require that the calculation of energy performance of new buildings shall be carried out using a methodology approved by the Secretary of State under regulation 24 of those Regulations.
