Do we do a 4 ton skip? Well, not exactly (since the EU ruling), but we do do a 4 cubic yard skip (or Midi Skip). The term "4 ton skip" or "4 tonne skip" (for those born after 1974) is slang within the construction industry, especially around the Liverpool and Blackburn areas of the UK, for a 4 cubic yard skip (which in itself is slang because it should really be a 4 cubic metre skip, but why push water uphill?)
You can get a clear idea of skips sizes provided by topskips here (if you want to read and listen) or here (if you want to watch skips on video).
