Our aspiration remains that the worst-rated properties are targeted and treated first.  On further reflection, we recognise that WHF funds are most likely to be combined with ECO funds to deliver improvements to both insulation measures and heating systems.  On that basis we are prepared to allow a maximum of 60% of the Funding Amount awarded by WHF to be directed at Band D properties in the private sector only.  In the social sector, the cap of 30% will remain around Band D properties.
