You can publish freqs in the UK. UK Scanning Directory is the biggest reference book here. 9th edition came out recently. There are (or at least were) a couple of websites that had digitised versions of an older edition). The Shortwave rag has published a Cd of UK freqs based on the PROMA list and more recently they did a follow up though I'm not sure what the sources for that were.
Plenty of yahoo groups about UK scanning including at least two that cover the area around County Durham. Also lots of info available on usenet via the uk scanner group.
