Which side to ride up a one way street in the UK?

The road in question is a back street with cars parked down the left side. I habitually ride on the right, i.e the opposite side to the parked cars to avoid the door zone, pedestrians crossing between and also because at the end of this one way street it widens slightly, splitting into 2 marked lanes and I want to go right.

I ride about 2ft out from the kerb and there is enough space for a car to overtake and even though closer than the advised 1.5m is perfectly safe as far as I am concerned as long as the car driver is willing to take the door zone risk and cope with the novelty of passing a cyclist on the left.

However this morning I was tailgated by a rather angry and unpleasant old man sounding his car horn. Having ascertained that he was not an emergency vehicle I just carried on, all of 200m or so and stopped at the traffic lights, diagonally across the right hand lane (I always do this to dominate the lane). He stopped his car less than 3 inches from my back wheel and pleasantries were exchanged.

The gist of his complaint was that I should not cycle on the right side of the one way street.

Rule 143 of the HC would appear to back me up, but as a rule of thumb which side of a one way street is best for a cyclist?
