Vauxhall Astra loosing power when heater fan is on

Car: Vauxhall Astra
Variant: 1.6
Model Year: 2008
Categories: Running Rough, Starting & Power Loss
When interior fan is turned up engine starts spluttering as if it's going to cut out. There are no warning lights on and was running fine until today.
Any ideas?
