The Communal Heating Trap...
Residents in an 'affordable' housing development in Edinburgh are facing a 450% increase in their gas bills. According to this BBC news article.
They were paying just 4 pence per kilowatt hour, but this is set to rise to over 22 pence per kilowatt hour.
The Harvesters Way development has 180 residential properties all served by a communal district heating system.
The average rate is 7 pence per kilowatt hour, so these residents used to benefit from a social tariff, but this has come to an end and now they are exposed to market rates.
