You don't actually need a HH anything like that.  Rain would never exert that much pressure on the fabric, and in any case the seams and zips would almost certainly leak first.

Yep my 2000 hh as had as much rain as my 5000hh......neither have leaked!!!

I think manufacturers use it now as 1 upmanship.........like razor blades! 2 blades on a razor then 3,4 now 5!!!.......but now i have 5 cut marks instead of 1..!! 

Hydrostatic Head is like country miles, one manufacturers 1500mm is another companies 3000mm.

Also it depends upon what the tent is made of. Mine is made of a technical fabric and even though the HH number is low I'll stay dry what ever the weather. If I remember to shut the  windows!!!

My son recently got caught in a downpour whilest sleeping in a small dome tent with an 800mm HH and he actually stayed drier than his mate in his 2000mm tunnel tent (but it was actaully the seams that leaked rather than the flysheet)

We had a 1500hh eurohike and it leaked like a sieve! Not just at the seems but right through the material ,it was more of a water filtration device than a tent!

3000mm hh should be fine in the uk
