Chaps,
I've found a 3rd water tank in the place, a small-ish one.
There's a large one (I presume for the hot water tank) and a small one directly above it (for the radiators I'd assume) and then tucked away another small tank at the same height as the large one.
Any suggestions as to what it could be for?

You should have generally speaking. A small header tank for the expansion of your central heating.
A quite large tank cold water storage/ drinking water to all of your non mains powered taps (often every tap bar the kitchen sink cold).
Not sure what the 3rd is. If it's another cold water storage tank, it should be connected to your other cold water storage tank. Two tanks become one body of water.
Has it got water in it? If so is it clean clear water, or murky brown water?

Our house has an extra 3rd small tank as we have a power shower, this needs a minimum amount of cold water so instead of a new bigger main tank a small feeder tank has been added.
Ah, I wonder if that's it - there's a power shower on the floor below - I'll have a look at where the pipes are running.FlossyThePig said:

I thought drinking water must come straight off the mains as storage tanks can become contaminated.Regulations have been tightened up on them so you can't (like many older installs) have an open to air tank in your loft. Water in them has to be potable. There has to be a sealed lid in place to stop contaminants coming into contact with the water. Vent pipes coming into the top of them have to be sealed and the overflow pipe has a mesh filter so that things can't climb in them that way.
I have been in a loft where the drinking water and central heating tank haven't had anything over the top of them. The central heating tank had a few dead bats in it.

Could be a separate header tank for your hot water tank, though most just use the normal cold tank.
That would only be in a sealer (pressurised) system. Older central heating systems were open and have a small header tank which, of course, couldn't use the normal water tank because of the chemicals (inhibitors) you add to the water in the central heating system. RichB said:

Sorry for slight thread hijack 
Gingerbread Man, be very careful when you find bats in lofts, when we had or central heating upgraded 3 years ago I learnt that disturbing bats is a big no-no. You get a fine of 1000 pounds per bat.
Sorry but computer problems mean I can't do the pound sign
