Love it when I do a quick search for a QGIS plugin and find exactly what I want - today I wanted an easy way for a non-GIS specialist to find a UK postcode in QGIS. The ZoomToPostcode plugin (https://plugins.qgis.org/plugins/ZoomToPostcode/#plugin-details) does exactly what I want!
@robintw Seems it downloads a postcode file datestamped 2014... Could probably use an update...
@geospacedman Ah that's interesting... Maybe I'll see if I can do a PR
