Annex C. Aggregate Funding Available from IGC

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.
