Would it be worth taking it to a garage for diagnosis or is there a way I can be certain that it is a heater valve by looking in the engine bay?

The car recently had the head gasket replaced, so could a hose be on incorrectly?

Don't take it to the garage yet.......
If it is non AC follow Luke's guide below to check the Heater Control Valve.
If you have a dribble around the accelerator pedal, check the plastic seal / gummet on the door pillar, (a little more than half way down I think). You can check by drying around it as well as you can and running water from a garden hose, with the door both open and closed.
Take Care,
