This graph shows
how the oil cost for heating has varied over the last few
years. The costs do not totally reflect changes in the oil
price because I try and purchase at the best time/price.
This means for instance the oil purchased in 2006 was cheaper
than it could have been because I purchased just before a
lot of the rises that year. In addition where multiple oil
purchases occurred I have averaged out the costs. 2007 has
seen the cost of oil creeping up again despite efforts
to get the best price. |
