This briefing attempts to produce an indicative figure for how much extra households in Scotland are going to
have to pay for climate change mitigation as a result of the methodology the Scottish Government is using as
opposed to the methodology Common Weal proposes. It draws on two main reports; the Common Home Plan
(a costed, comprehensive Green New Deal for Scotland) and The Retrofit Challenge (a more detailed paper
on how to retrofit houses for energy efficiency written by Scotland’s leading retrofit architect) then uses two
modifiers to indicate how much extra it will cost to do it the way the Scottish Government is doing it, one to
cover the profit they are inducing to incentivise the private sector to do the work and one for the inherent
inefficiency that that creates.
It concludes that the average cost to households of climate change mitigation work is in the order of £46,000
– but that in addition to that the private sector model favoured by the Scottish Government adds an additional
£9,800 in profit and extra inefficiency taking the total per household to over £56,000. If the cost of replacing
petrol vehicles is included the cost to households rises to over £100,000 of which about £20,000 is an
unnecessary premium. These are average numbers and the figure for some households will be much higher.
The public is not being told about this honestly and nor is there an open and honest debate about whether this
is the right way to go about the work of decarbonising our homes and our lives.
