Paul, we are from South Africa too.

The S.A. plug pins will not fit into the Qatar sockets.The plug sockets here are the same as in the UK.

What we have done is this - get a multi adapter from South Africa - the one with 4 or 5 multiplugs on a lead, all you do is replace the plug on the lead to a Qatari one and plug your current S.A. plugs into the S.A. adapter.

Two pin plugs work the same as over here.

Voltage is the same as in South Africa - so no worry about the currency being different.

Regards
Juan
