You can beat this by using a heat pump: you pay for the energy needed to operate a machine  which transfers energy from the environment into your home. The heat energy you get can be a few times more than the energy you pay for.
The problem is, where to extract the heat from. It can come from the air outside, but that needs a big box with noisy fans, usually installed in the garden. Not easy in most flats. Or, it can come from the ground - but this needs a large area to bury pipes, or a deep (expensive) borehole. Not easy in a flat. Or it can come from water. Does your flat have a lake or river? 

I would like to see some science behind the air/ground source heat pumps.  Given that we don't get something for nothing and that nature abhors a vacuum and will always try to equalise itself; if we take heat out of the ground, nature will try to put it back in again by taking it out of the air, therefore the air temperature (admittedly localised) will drop.  Some may say this is good as it will reduce the temperature of the planet and counteract global warming.  I question it and am ready to be educated as to why we seemingly get something nothing.  Also the temperature of the ground at 11 degrees will not heat up a house without the use of compressor and some form of medium, think reverse refrigerant.  The system has to be powered by something, say electricity which also is not free!  I have also seen reports that any system like this will not heat stored water above 50 degrees; perfect breeding ground for legionella.

Please have a quick search online about how heat pumps work! The best thing is they can be used to heat and cool, providing you get the correct unit! They will probably be the main source of heating in the future!!
