Hi I have a maintenance contract with British Gas for £12.50 per month on a
15 year old gas warm air heating system and hot water. Am I throwing money away, as has been suggested by a friend, or would it cost more to pay for a yearly service and to pay for any repairs that need done. I am already thinking of replacing the thermostat myself to a more efficient one which has different temperatures for different times of the day and days of the week etc so should I cancel the gas maintenance contract(after the next service of course)?Thanks Ron
