Nicholas Thistlethwaite's work as an independent organ adviser has included instruments of many types and periods. As a diocesan organ adviser he has wide experience of architectural issues and his work as a cathedral precentor makes him familiar with the liturgical and musical setting of worship. In addition to overseeing the restoration, reconstruction or replacement of existing organs, he undertakes research enquiries, gives advice on grant applications, and prepares 'one off' reports for those considering their future options.
