I'm so confused and worried about the running costs of my heat pump. Please help!

Hello everyone. I'm not at all technically minded and am disabled cognitively so please bare with me. I am a social housing tenant and I live in a 2 bed small detached bungalow built in the 60s in a very rural place. About 3 years ago my housing association took out my economy 7 and replaced it with air source heating. Daikin I think it's called. I have 4 small solar roof panels and a solar boost to heat up hot water. It's been very very expensive to run this heating and my landlords can't explain why it's costing me more in electric than the 5 bed house opposite me . There is no underfloor heating here, Radiators were changed but only one seems extra large, the rest look normal, landlords are saying it's well insulated etc, double glazing. There are air bricks all around the outside though, about 10 or 12 in total. My energy supplier, based on last winters usage, wants 400 a month from me. I know prices have risen and cost of living etc but I can't afford to turn this heating on now at all . 3 different people who have come to look at the heating have said this system is expensive to run and known for that. My landlords say it's because I don't have carpets apparently, I have laminate and rugs. The bungalow has suspended floors. Landlord says loft and cavity wall insulated. Double glazing. The heating never seemed to warm the place up properly, yet costs a fortune to run. This winter I've had to make the choice not to use the central heating at all so I have got a couple of small oil filled mobile radiators that I will use, but I'm dreading winter. Please can someone tell me WHY this heating has always been so expensive to run, I've never got on with it, been told various things like it's calling for heat all the time it's on because it's never reaching temperature, heats going straight through floor etc, that the system is not suitable for this property, but my landlords insist it is. I am dreading the winter, I couldn't cope last time yet alone this time. Please can someone talk to me about this heating, why it's so expensive. I've just told my landlord I am not even turning it on this winter but they say I have to or pipes will freeze? I have no log burner or open fire here. Are oil filled rads enough? It's a Daiken system air source. Please can someone try to explain this system to me and why it's so so expensive to run. Thanks so much.
