Hi im new to this i have a 1.6petrol focus 11 plate im using alot of antifreeze water seem to be topping it up all the time 

I'm not sure what you want us to say. You either have a coolant leak causing it to spill on the floor or you have a bad head gasket causing it to contaminate your oil and burnt in the combustion chamber.

Also, if the drivers side carpet is wet, you may have a leak from the pipe that supplies the heater matrix - all sorts of potential problems for you to lose sleep over!

Or a leaking water pump. You can test for a head gasket by either getting a garage to do a pressure test, or a sniff test, or you can buy your own sniff test kit, which is some chemicals that change colour when they detect exhaust gases in the coolant. 

You need to check or have a garage check the cooling system for leaks. There is nothing more right now I don’t think can be advised. Without someone physically looking anything here is just a stab in the dark I’m afraid. 

Ok thanks guys ive got a warrenty on the car so ill get it sorted thank you all for your help
