Retrofit Assessor Scheme

Elmhurst's Retrofit Assessor scheme is TrustMark approved and operates in conjunction with PAS 2035; the specification for the energy retrofit of domestic buildings.

Members of this scheme can undertake Retrofit assessments for domestic properties as part of the PAS 2035 process. 


Why join Elmhurst's Retrofit Assessor Scheme?

Our involvement in the preparation of PAS 2035 has allowed us to develop a professional scheme which will help members to deliver quality retrofit assessments in accordance with this industry recognised standard. 

The quality mark

As a member of this scheme you will have access to the coveted Trustmark which demonstrates that you have been registered with an approved scheme to deliver PAS 2035 retrofit work.

Access to professional online tools

Members of the Elmhurst Retrofit Assessor Scheme will have access to a suite of online tools which can help them to deliver a quality service to clients. These tools include:

This flexible reporting tool allows members to create a room by room report of a house.

Members can enter multiple ‘items’ within a room and can provide a brief description of their condition. A star rating can also be attached to each room to represent its overall condition. In addition to this, pictures can be taken and attached as evidence for each part of the report.

With this information the Condition Report tool can generate a PDF file with all the information entered in a clear and professional format. 

This conversion tool allows users to upload Elmhurst formatted RdSAP data, which then creates an Elmhurst Design SAP input file which can be passed to Retrofit Coordinator.

Expert technical support 

Members can access free technical support directly from experts in the field of retrofit assessment. Our support team works tirelessly to ensure that members receive the best service and support in the industry.

Access to technical documents and updates

We ensure that our members are ahead of the game by providing technical documents and industry updates to ensure that they are constantly expanding their knowledge base.
