CELEBRATING 150 YEARS
REHIS woven into the fabric of Public Health in Scotland
As part of the 150-year celebrations, the Institute has designed a colourful tartan that cleverly uses the Institute’s history as inspiration. Created by Tartan Caledonia, the design incorporates the colours of the official REHIS crest and boasts thread counts that mark the year of our inception, 1875: 18 for green, 7 for black and 5 for yellow. The main central design (in blue and red) adds up to 150 threads.


The Institute was established after the merger of the Sanitary Association of Scotland (founded on 20 January 1875) and the Scottish Institute of Environmental Health, set up in 1973. The two organisations merged in 1983 to form The Royal Environmental Health Institute of Scotland, often referred as REHIS. In 2001, the Queen signs the seal for the Institute to be incorporated by Royal Charter.
The vibrant design was registered on the Scottish Tartan Register, on 20 January 2025 as a permanent reminder of the vital work of REHIS, a very special tartan reflecting our long history.
