Fuel poverty is currently defined as the condition in which a household is required to spend more than 10% of their income on maintaining an adequate level of warmth in their home and on power. Adequate warmth is defined by the World Health Organisation as 21°C in living rooms and 18°C in other rooms. The Mayor of London, taking into account the high cost of accommodation in London, has adopted an enhanced definition which calculates 10% of income after housing costs and this is the definition that Islington adheres to.
Islington Evidence Hub produced a factsheet in October 2013 on fuel poverty in Islington. It shows that 53% of single pensioners in private sector housing in Islington are fuel poor and 31% of private tenants are fuel poor.
