The primary purpose of lot 1 is to provide funding for first time central heating measures and therefore the finances within the lot 1 bid document should only relate to the costs of installing first time central heating.  Our expectation is that other industry schemes will be accessed to ensure that insulation measures can be funded and installed prior to the heating.  Where measures may not be considered economically viable e.g. industry standards might suggest something like external wall insulation, but it may not be feasible from a cost perspective, this should be documented in your proposal (if specific properties or archetypes are known at that stage) and referenced in any future Funding Use Report.  Successful recipients can apply for ‘gap funding’ by contacting the WHF team and providing appropriate documentary evidence of the shortfall. For the avoidance of doubt the WHF team are under no obligation to provide such funding.
