Just one question @thisisausername , you mean that you would do an "integrated master degree" and that they will accept the work experience as part of the education/ educative charge?
answering to your situation, It's not what you have been ask in work to posses in degrees. Education and work go different lines. UK is in a 3 tier system (Bachelors, master, PhD). The only way I know of doing a master degree without a bachelor is doing an integrated master degree. Where they make the bachelor and master together. A kind of 3+1= 4 years. In this cases sometimes if you have experience, certification etc you can validate a great part of the education process. Add some credits by exam or heavy load credits per semester and you can get a master in 1.5 to 2 years (maybe even less, I guess).
In the past(or still in some very concrete cases) other countries had similar degrees in Europe like Germany Diplom (which could last 5 years or 300 ECTS), not to be confused with Diplom(FH)(which was a bachelor), or the Spanish Licenciatura (which could be a bachelor 4 years with 240 ECTS or 5-6 years master degree 300-360 ECTS). In this cases you where doing 300 ETCS, or 150 US credits, of AOS content, beeing very focused degrees on the study at hand.
