Switch Oil to LPG?

propane produces around 7kwh per litre and oil is 10.35 kwh per litre so dont compare cost per litre but costs per kwh. Based on the figures quoted above lpg at 38p/l = 5.43p/kwh compared with oil at 54p/l +5% = 5..48p/kwh. Bear in mind that you might also end up having to pay a tank rental charge.

An air source heat pump is likely to give you an SCOP of around 3, so with leccy at around 21p per kwh heating with an ASHP will cost you around 7p/kwh but who knows what is going to happen with the price of oil, lpg or leccy over the next few years.

It's a fallacy that you need a well-insulated house to benefit from a heat pump, you just need a heat pump with a larger output.  That should be equally true of an oil or LPG boiler but typically these are way oversized for heating your house in order to give you hot water quickly.  You did need to meet certain standards of insulation to qualify for the RHI, a government subsidy for heat pumps,  but it's probably too late for that now anyway.
