My elderly parents had an oil company on a keep-me-topped-up arrangement. When I found out I knew it needed checking and sure enough they are hiking the price up by about 30% and taking it by direct debit. This was Certas but I know the other oil companies do the same. I have used boilerjuice for some years now and they are great because you always get a keen price but I can't get them to supply my parents because you have to order the oil each time, pay up front and you have to be able to say what quantity you want.
So how do I find an oil company that will supply oil without fuss, just to keep the tank part full and without robbing my dear old parents? A modern day problem.
