Historic England

Historic England in the United Kingdom is inviting bids for “ITT - Investigation into case studies of AVCLs installed in buildings of traditional construction - UID 333M”. Bids close on 12 October 2026; the estimated value is £15,000.

The work

Historic England is looking to support research which will inform guidance on the suitability of retrospectively fitting modern technologies into English buildings of traditional construction. Following the publication of an earlier literature review, this project aims to help fill the gaps in current knowledge by offering insight into traditionally constructed buildings which have been retrofitted with AVCLs (Air and Vapour Control Layers). The project will review a selection of case studies and report on the findings, including any positive or negative consequences, of the installations. Full details can be found in the invitation to tender.
