Not a new link (April), but nice to see confirmation of the advice I have been passing my coaching clients and colleagues for 18 months now - that is to say indeed.co.uk is THE site to conduct your job search.
Just did some benchmarking with simplyhired, the other large aggregator - and found they had lots of "dead" jobs and broken links
Classified lives online now: homes has rightmove, motors has autotrader - and now at last jobs has one site with coverage of 90% of the market

One coda to this - not convinced it is picking up .gov.uk (ie local authority roles) consistently.
Advice is to look separately on your local council's careers site if that is of interest to you
