RED DIESEL or Kerosine (Blackpool FY3)

I have just purchased a diesel heater (for home use), but supplies available locally appear to be 4+ times the price applicable to large quantities.

The property I am in (sort of) currently has no kitchen/bathroom/central heating/ceilings/internal doors or plaster on the walls - and it sometimes feels warmer outside than in.
Being able to run the heater would provide the motivation of further me clearing the house for the workmen to proceed, but finances are EXTREMELY limited & it would be grately appreciated if you had any heater fuel you might not be planning to use. (I do feel a little embarrassed asking).

THANKS FOR READING.
