Introduction of an Infrastructure Charging Mechanism in Scotland: research project
This research focuses on the options for an infrastructure charging mechanism.
Annex C. Aggregate Funding Available from IGC
The table below shows extracts from the calculations of aggregate funding available from IGC based on a summary of the value distribution estimates. The first group is for market and affordable housing.
Then an estimate is made for non-residential uses with IGC applied with the same thresholds of minimum value and rate formula as for residential.
The estimate of aggregate funding through the flat rate mechanism (at £30 psm) is shown below the estimate based on the non-linear formula.
