A Building Preservation Trust (BPT) is an organisation whose main aims include the preservation and regeneration of historic buildings. BPTs normally have charitable status.

There are around 18 BPTs in Northern Ireland. Their activities can include the acquisition, preservation, reuse or onward sale of an individual building or types of building. Trusts that work on a number of simultaneous or successive projects are known as revolving fund trusts.  BPTs operating in Belfast include, Hearth Revolving Fund, Belfast Buildings Trust, Templemore Users Trust and the Ulster Historic Churches Trust.

Guidance and advice on setting up BPTs is available from the Association of Preservation Trusts NI (contact details in Section 6).
