I live in a small, newly built flat in London. The walls are plasterboard. In our bathroom, the only lights are two halogen down lighters on the ceiling. I would like to install two new lights on the wall either side of the mirror.
To make things harder, I don't want to go upstairs and ask the guy who lives there to pull up his carpet.
Is this something I can attempt myself? How do I get the wire from the ceiling light across the ceiling and down the wall to the new lights?
Added: I own this flat. The lights are proper bathroom lights, from a bathroom shop. They are not within reach of the shower, but they are obviously within reach of the sink. There is no actual bath in the room.
Please don't be distracted by the fact that this is in a bathroom. Really I would like to know how to get the wires from the ceiling light to the wall light.

One thing I've been surprised at doing my house is that getting a plasterer is easier and cheaper than you might have thought. So, be brave.
Take down the bits of ceiling and wall that are in the way, drill proper holes in the joists and noggins for the cable runs and lay the cable in. Wire up the other end of the cable, then tape over the ends of the cable where the wall lights will go.
Next get some plasterboard -- B+Q usefully sell it in half-size sheets that fit in a car -- cut to the size of your holes (with little holes for your cables), and nail to the joists in the ceiling and the noggins in the wall. Don't worry too much if there's a few mm around the gap, it doesn't need to to be too precise.
Then have a plasterer put a "skim coat" over the top of the lot. He or she may even say it's cheaper and easier for them to do the whole ceiling or the whole wall. Stand back open-mouthed while they do the lot in a few minutes!
Oh, and I'd take @Tim Baker's suggestion of picking up the power from the switch. Given that you're in the UK, if the wiring was done in the last forty years this is going to be a pull switch on the ceiling, no?
(Usual disclaimers apply: be careful mucking about with power in the bathroom, it makes sense [and is required by the Building Regs] for a circuit that's going to a wet area to be protected by an RCD.)
