We have no mains gas here and electricity is a small part of our budget. We are seriously affected though by the price of oil and have seen some huge ups and downs over the past three years. Reasonably low at the moment but I follow Boilerjuice quite religiously, trying to guess the trend so I know the optimum time to fill the tank.
At this stage we have no plans to cut back but the last thing we would do without is visits to the USA to see our daughter. We might have to cut down on the frequency and choose cheaper carriers but it would be heart wrenching not to see her at least once a year.
