For a start you could insulate you hot water pipes!
Can you time how long before the boiler fires up?
Once fired up it will take about 10-12 seconds for the inside of the boiler to warm up.
Is there a preheat facility on it? Of course using that costs more in gas than you save by running a little cold water for a short while.
The boiler should fire up at about 2.5 litres per minute so even if it took a whole minute to run hot the cost of 2.5 litres of water is still far less than £0.01.
There is no shortage of water because the planet is 80% covered with it!
