Hi, I need to buy a hosepipe that is 250m long. Is there somewhere that I
can buy one, perhaps straight from a factory or something?

Try a farmer's store - where they sell cow pruners, sheep openers and
the like. These are great fun to shop in - all manner of weirdness, and
the proces are often good too (3kg of copper sulphate for a tenner!)

However 250m is _very_ long. You may need significant water pressure and
you'll still get poor flow. Make sure the hose is big enough diameter.
If possible, use a shorter hose with couplers - when you can, just used
the short length alone.

250m.
Comparing to a 30m length of hose, that's 8 times longer.
Or if a standard mains pressure is 3 bar, or 30m of water pressure,
you're looking at about 4m of water pressure.
About equivalent to a normal length of hose on a tap fed from a cold
water tank in the house.

Probably not even that good.

I got a new 30m hose on a reel earlier this year (how _did_ I cope with all
that excitement at once?!!!) & being a lazy toad & eager to use it I
connected the existing hose (about 13m long, for some reason) to the input.

The flow rate drop was dramatic - one of those sprinkler gun things on the
end of it went from being "very good" to "usable but not great" in an
instant.

And that was with a mains feed to the cold tap & pretty decent water
pressure.
