Oil Central Heating

Obviously not ideal - but can anyone tell me through experience whether this is/should be a deal-breaker on letting a home? 

Cost vs. Gas?

Thanks...

We use oil as our village does not have gas.  Out here the choices are oil, electric, or bottle gas.   The vast majority of people I know use oil.
I  order 1000 litres at a time, usually having to order 3-4 times a year(but we live in a very poorly insulated, drafty house).  It can vary from £380 to over £400.
