Building an extension for which I need about 1 - 1.5 Cube/Mtr of
concrete delivered

As the extension is at the back of my house, my only options are to
Wheelbarrow it down (up several steps) or
have it pumped in. (distance is about 35 meters)

I've been quoted between £240 - £270 +VAT for 5 hours on-site by
different "Concrete Pumping outfits" - which seems rather a lot of money..

Does anyone know of any alternatives? Can't concrete delivery companies
pump it straight from the truck?

Cheers,
Arno
