I have been asked to reply.
In order to avoid potential confusion, Warm Front customers are only invoiced for the costs of works required that exceed the grant maxima (£2,700 for gas heating and £4,000 for oil). Currently, contribution letters provide customers with the costs of any previous Warm Front measures to the property (which are deducted from the new grant), installer labour costs (harmonised by region) and costs for any required materials (set centrally across the country).
As regards travel expenses, individual jobs do not attract different charges depending on their distance from the contractor.
The scheme's management fees are not taken from the grants of individual Warm Front customers, but rather from the central grant fund made available to the scheme.
