Rachel MacSweeney, based in Winterton, Norfolk, has two holiday cottages and her own house, all of which use heating oil.
She told BBC Radio Norfolk’s Rob Butler she ordered 500 litres for her own house on 25 February which cost her just over £340.
But on Tuesday, when she ordered for one of her cottages, she ran into issues.
“I went to my regular supplier and couldn’t order anything online – they weren’t taking online orders,” she explained.
“I called them and they quoted a delivery time of 15 days, which is unusual; they weren’t able to give me a price, but added my name to a waiting list.
“That same evening I tried an online comparison website. Again no oil available from the 200 suppliers they checked, so at this point I’m starting to panic because we need oil.”
She tried again later that night and found 500 litres for a cost of £658. When she looked again the next day the price had risen to £750.
She said she had to consider closing up one of her cottages and added that if prices did continue to rise, she would have to find alternative heating methods.
