thanks in advance,

Marine aquatic stores, they all have Reverse Osmosis systems and many of them sell tanks of RO water for marine aquatic use, you may have to bring your own container though.

One place in central london is the Aquatic Design Centre (http://www.aquaticdesign.co.uk/) though I've not bought from there myself (we're a bit far out and I'm not lugging tanks of water on the tube)
