Easier than you think, though the official disposals price is circa £150,000 for a scrap helicopter but they do find their way to scrap yards at prices that are more realistic around scrap value, and of course still need to get moved around on a flatbedI think that's probably a little out of the league. Finding scrap aircraft is hard in the UK, not like the US, and transporting it if you do find one is even harder. Especially since he says there is no vehicle access to the site.
Certain scrap yards will pick them up and sit on them for collectors and airsoft or paintball
sites etc
