To ask the Scottish Executive what information it has on the estimated percentage of the extra fuel required to heat houses in (a) Edinburgh, (b) Glasgow, (c) Aberdeen, (d) Dundee, (e) Stornoway and (f) Braemar compared with identical houses in Bristol.

The estimated percentage of extra fuel, compared to Bristol, used to heat a "typical" semi-detached and detached house with gas central heating and with non-white meter electric heating in those locations is shown in table 1:

Table 1: The % of Extra Fuel Used Across Scotland to Heat a Semi-Detached and Detached House with Gas Central Heating and Non-White Meter Electric Heating, Compared to Bristol

These estimates are based on National Home Energy ratings (NHER) calculation methods.

This information is sourced from the Scottish House Condition Survey (SHCS). As the SHCS is a sample survey the estimates are subject to a degree of uncertainty.
