This is the first time I find a useful website for oil price comparison, so thanks for this! I did a price check in boilerjuice and, although I think the service they provide is very good, when I checked against my oil provider (Total Butler - Hampshire) the price per litre was 40.62 against the website at 42.00. The reason it is cheaper might be because I have a direct debit and pay a fixed monthly amount. Worth checking anyway.
