PAS 2035 Whole House Retrofit Schemes

Elmhurst operates a TrustMark approved Retrofit Assessor and Retrofit Coordinator scheme in accordance with the Publicly Available Specification (PAS) 2035; the specification for the energy retrofit of domestic buildings.

Members of these schemes will be fully qualified to undertake work within domestic retrofit projects in accordance with this new standard.   

PAS 2035 explained

What is PAS2035?

PAS 2035 (PAS 2035:2019 Specification for the energy retrofit of domestic buildings) has been developed as part of the Each Home Counts process and is the over-arching document in the retrofit standards framework, with which holders of the quality mark will be required to comply when carrying out domestic retrofit work. 

When considering the government's ambition to reduce fuel poverty and carbon emissions, it is evident that more needs to be done in order to improve the UK's existing housing stock. The Each Home Counts review was established to tackle the high level of failure present in domestic retrofit, and determine a better process for the retrofit of energy efficiency and renewable energy measures. As a result of this review PAS 2035 was introduced as the standards framework document for the end-to-end delivery of domestic retrofit work. 

This new framework provides a whole building approach to the retrofit process. Rather than retrofit work being considered in isolation (which can unintentionally damage the overall building performance), the new approach looks at the home, environment, occupancy and the householders' improvement objectives when determining suitable measures to install. Overall the process introduced by PAS 2035 is designed to improve the quality of retrofit work for domestic properties. Ensuring that funding from banks and lenders is used towards good quality work which will actually improve the energy efficiency of housing.

It is expected that in time ECO, and all other government supported retrofit projects, will require compliance with PAS 2035.

The Application

PAS 2035 aims to be used equally across the able-to-pay and funded markets. The standard can be applied to all domestic retrofit activity covered in the following categories:

  • Retrofit promoted/ funded by national or local government schemes
  • Retrofit promoted/ funded by landlords, including social housing organisations, private landlords in the domestic sector and commercial property portfolio holders.
  • Retrofit of individual buildings by their owners and/ or occupants, including both domestic and commercial owner-occupiers.
  • Retrofit that is integrated with and forms part of broader repairs, maintenance and improvement (RMI) activity related to individual buildings or building stocks.

The quality mark 

A quality mark has been introduced for the domestic retrofit sector which is overseen by the Government Endorsed Quality Scheme, TrustMark. Retrofit Assessors, and Coordinators require this quality mark to show that they have been certified by an approved scheme (such as Elmhurst Energy) to deliver retrofit work in accordance with PAS 2035. With this quality mark they can also demonstrate to consumers that they have the skills and knowledge to deliver the best practice standards and trading practices in the sector.
