Register of Architects
Accredited in Building Conservation


The AABC relies on the hard work and support of our volunteer assessors. All applicants are judges on their own competencies regardless of the size or scale of a project in their case studies. There are assessment teams across the UK, and all applications are assessed by a team distant from the applicants' locality.

Each application is assessed by a team of two AABC accredited or retired AABC accredited architects and one layperson suitably experienced in building conservation. 

The Assessment Team

Lead Assessor

An AABC accredited architect who leads a team of assessors looking at an application. They help the team come to a unanimous decision on whether an applicant should be/ continue to be accredited with the AABC. The lead assessor conveys this decision to the supervisory panel and any comments that should be sent to the applicant. 

Architect Assessor

An Architect who assesses applications to see if the competencies required by the AABC are shown. They then comment on whether an applicant should be/ continue to be accredited with the AABC.

Lay Assessor

A lay assessor is a person with knowledge and experience of historic building conservation but is not an Architect. The layperson represents ‘an intelligent client’ when looking at the applications. They are a critical friend who reads the application and gives relevant comments from the client’s perspective, i.e., someone not knowledgeable in all architecture terms.

Supervisory Panel

The Supervisory panel is a small group of AABC accredited architects who moderate the assessment teams’ decisions to ensure consistency across all applications. The panel is made up of at least four people. They identify applicants who produce exemplary applications and invite them to become architect assessors.
