We know the number of households, by income decile that are living in homes rated EPC C to G in Hartlepool shown in the chart below.
Using the number of households by decile in homes rated EPC C to G and the average bill saving data, we can calculate the cumulative bill savings to 2034, 2040 and 2045 by income decile in Hartlepool.
Based on the type of houses different income deciles live in in Hartlepool we can calculate the investment required by income decile to retrofit each home. Using the 10-year, £60bn of public funding commitment from the Cheaper Bills Warmer Homes, we assume a share of public investment of 84% to homes in decile 1, 70% to decile 2, 55% to decile 3, 47% to decile 4, 22% to decile 5. All households in deciles 6 to 10 receive a 7% share of public investment, largely in the form of heat pump grants.
Taking the bill savings and the investment costs by decile in Hartlepool we can calculate the net costs to all households in 2034, 2040 and 2045.
We can then calculate the average net-costs to households by income decile in Hartlepool and compare this to the UK average in 2034.
The cumulative savings continue to increase through to 2040.
And to 2045.
Finally, we then plot the total share of public vs. private investment for each income decile in Hartlepool under the Cheaper Bills, Warmer Homes programme.
