The Scottish Executive's Central Heating Programme and the Warm Deal Annual Report 2003-04: BENEFITS FROM HOME ENERGY EFFICIENCY SCHEMES IN SCOTLAND 2003-04: A REPORT BY THE SCOTTISH EXECUTIVE

Effect of improvements

The effects of improvements in properties improved under the Warm Deal Programme can be described in the same way as those improved under the Central Heating Programme:

Change in the NHER.

Changes in predicted emissions of CO ₂, NOx and SOx. ¹¹

Change in predicted expenditure on fuel.

Effects of improvement on NHER

Properties improved under the Warm Deal (Eaga) were found to have an increase in the average NHER of 0.8 from 5.7 to 6.5. The average NHER of Warm Deal properties prior to improvement was significantly higher than that for those in the Central Heating Programme:
5.7 compared with 3.4. This is to be expected as many of the properties in the Warm Deal Programme already had some form of central heating, which was not the case for those in the Central Heating Programme. Figure 19 shows that prior to improvement privately rented properties have the biggest proportion of homes that are rated as NHER 'poor', almost one-fifth (18%).

Figure 20 shows the NHER improvements for different tenures improved by Eaga.

Figure 20

By comparison properties improved by the local authorities themselves improved by an average 1.7 on the NHER scale.

Effects of improvements on emissions

Total emissions of CO ₂ from both the local authority programme and those properties improved by Eaga are predicted to be reduced by 24,128 tonnes per annum, emissions of SOx and NOx are both predicted to fall by 61 tonnes per year. ^{12, 13}

Effects of improvements on costs

Predicted heating costs for households in properties improved under the Warm Deal (Eaga) fell by £55 on average, from £620 to £565. Tenants of private landlords saw a reduction in annual heating costs of £99, while housing association tenants benefited from a £26 reduction. Warm Deal (local authority) households are predicted to see a £139 reduction in annual heating costs.
