I want to install 4 bulkhead lights and switch them with a stand alone PIR. Are there problems with PIRs and this type of lamp. If so can anyone recommend a suitable PIR?

Some makes of PIR sensor aren't compatible with LED or CFL lamps. You should be fine if the PIR has a relay switch, avoid the types with triacs or scr's.

Not really, I'm in Cape town and don't know what products are available in the UK. Maybe someone more local to you will throw in a suggestion.

I would never recommend using CFLs on PIRs. They take a significant time to come up to full brightness and switching them on and off repeatedly will reduce their life. I suggest using ordinary GLS lamps or the halogen replacements. Also, unless the lights are on for long periods, which is unlikely in most situations where a PIR is used, then the energy saving by using CFLs will be trivial.
The PIR I've installed most is this one:
Spectra - 200 deg PIR Sensor 1kW Load - Black
Good wide angle and appear to be reliable.
