Here some RSS feeds or Job/Opportunities pages from Arts Councils in UK.
Most of these sites used to have RSS feeds but most have dropped them and only have a webpage or search page, so we can’t provide a updating feed.
(RSS is better by far… but that’s the way the web goes 😉 Just my opinion.
Arts Council England
