Conservation accreditation schemes
Working with older and historic buildings, traditional (pre-1919) buildings and designated buildings, such as Listed Buildings, calls for a particular set of skills and expertise. To gain conservation accreditation, professionals have to submit evidence of their knowledge, skills and experience. Registers of accredited professionals can be used to find professionals with the prerequisite skills.
Some grant funders, including Department for Communities Northern Ireland, Historic Environment Service (Cadw), Historic England and Historic Environment Scotland, require the use of accredited professionals, so it is important to check the funding requirements for the project.
Further details on the conservation accreditation and certification schemes that exist for the range of professionals, and on when using conservation accredited professionals is required by grant funders, can be found on Historic England's website.
