Non-agency jobs?

Im in the US and am looking for a job in the UK.  I get positive replies, but EVERY job I apply to seems to be an agency.  I dont know its an agency until I already apply because I use reed.co.uk which is a good site otherwise.

I really dont want to work for an agency because (at least from my experience) theyre too often sleazy and/or dont know what theyre doing.  And the jobs Im looking for arent exactly hard to come by.  I have experience in mental health, so thats what Im looking for and I know that you can walk into any mental health facility and they will have LOADS of job vacancies because nobody with any sense wants those jobs.  Why should I enrich an agency for "finding" me? 

So are agencies just virtually the only way people get jobs there or can I deal directly with the hospitals and facilties?  Also, is there any way to find out how reputable a particular agency is?  Im suspicious of one place that replied because it seems they deal almost exclusively with finance jobs, but the particular jobs I responded to were mental health-related.  Mental health is not finance and the jobs were not listed on their corporate website (only on reed.co.uk )

Best way to find jobs directly with the company is in the local paper or on the companys website. If you're using job seekers websites, you'll get mostly agency listings.

And in my experience, agencies in the UK are much better than those in the US. You do have your bad ones but when I was starting work in the UK, they were very helpful and gave me the information I needed for the work culture in the UK.
