You need to cure the damp and condensation which permits it to grow.

Bleach cleaners will kill it, but it will always come back until you cure the excess humidity.
thanks for the speedy reply, I've just cancelled my napalm order 
I think I need an extractor fan fitting in the bathroom, can I fit it in the hole that the vent to external air brick is? or does it need an extra fan fitting and also the air brick vent?

preferably a bathrrom fan should be fitted high up and far from the door, so it will draw dry air from the house through the gap under the door. Water vapour is lighter than air.
do not put an electric fan directly above a bath or shower as the electrity safety rules are then more onerous.
A centrifugal fan is generally quieter and more powerful than an exial one.

the air brick vent is above the bath, about 8 inches from ceiling. I popped into the local F*cus this afternoon to see what's on the market, there's alot of choice, so just one more question before opening the wallet.
do I need (or is it best) to have the fan through the wall or in the ceiling and exiting though the loft???? I've seen both.

Remove the silicon and replace it. No sealer remains free of mould in a bathroom in the long term.
through the wall is usually less trouble. If it goes through the loft it is absolutely essential to have a sealed duct exiting outisde the house, not steam blowing into the loft space.
You can get some good centrifugal loft fans at reasonable cost, but not those weedy little in-line fans that sit in a flexy pipe.
You must wrap the loft duct in loft insulation or it will get water condensing inside it.

I'd seen those in line ones and thought they looked a bit puney. thought about through the ceiling and out through the loft as I wouldn't have to cut through my tiles.
There are a number of considerations when selecting an extractor.
Many people opt for the ones that come one when the lights are turned on- that's fine if people only shower at night time but in reality people don't turn the light on to shower when it is light outside.
The most basic fan will have a pull cord or remote switch.
You might want to consider one with a movement sensor and over run. The down side to these (in my limited experience) is that they see ghosts and run for no obvious reason.
A fan with a humidistat will turn on when the moisture reaches a certain level.
You can get fans with a different combination of sensors to suit your needs.
B&Q will probably be quite limited in thier range so try someone like

I have linked to a specific type of fan- only because the site navigation is crap. I do have an icon 30 fan with humidistat and pir, I am happy with it but it is noisy (ie. the sound of the air rather than motor) and it does run when no one has even been into the room.
