There are relatively few examples of American shows remade for the British market (the majority of these being game shows), as the British television audience are very accepting of the American originals. Indeed the US remakes are often imported back into the UK. By contrast original British shows are rarely seen on the major networks and are usually broadcast only on the Public Broadcasting Service and cable television. This list includes a number of pilots not subsequently taken up.
1: The original show for Channel 4 was called "Scrapheap Challenge". When shown in the US this was re-titled "Scrapheap". When the program started to use US teams and a US presenter it was re-titled "Junkyard Wars" for both US and UK audiences. In the UK episodes involving UK teams remain under the title "Scrapheap Challenge".
