The message
from Owain contains these words:

It's usually *a* storage heater in the lounge. Storage heaters are
£100-200 each (for a decent fan assisted one), panel heaters in the
bedrooms £20 each. Of course, no gas supply is where the money is saved.

For flats I'd expect the cost of laying on a gas supply to disappear
compared to the cost of installing dozens of individual central heating
systems.
