Scottish House Condition Survey: Key Findings 2011

¹ The first 3 years of the continuous survey ran from October to September. In 2007 the survey changed to calendar years.

⁴ 'Other flats' is made up of 4-in-a-block, tower/slab and flat from converted house.

⁵ Note this is different from the classification used by Scottish Gas where the dwelling has to be within 23m of a medium/low pressure gas pipe to be on the gas grid. SHCS houses are mapped by postcode, reducing the accuracy of dwelling location to 0.5 km.
Maps of existing gas grid infrastructure are kindly supplied by Scotia Gas Networks.

⁷ It is assumed that all post-1982 dwellings are insulated due to the higher levels of energy efficiency required by building regulations.

⁸ The SHCS provides an 'enhanced level 0' evidence base for NHER modelling.

²³ The exact rise in overall fuel costs depends on the proportion of each of the fuels used by a household and the relevant charges for each supplier. Swings in prices will affect rural and urban areas differently.

²⁴ The average fuel price figure included in Table 24 and Figure 10 is weighted by the proportion of households using each of those fuels for primary heating as recorded in the SHCS.

²⁶ Indexed values for fuel price and median income are relative to 100 in mid-2005

³⁵ The definition of full central heating for SHQS purposes is: 'whole dwelling or rooms representing more than 50% of the floor area of the dwelling with the heating controlled from a single point'.

³⁶ The SHQS failures count is on a per-dwelling basis. Where an SHQS failure is to a shared element, e.g. disrepair to a party wall, this failure will be counted twice. As a result the true number of criterion failures will be lower.

³⁷ For the definition of SHQS 'serious disrepair', see SHQS Guidance Annex B http://www.scotland.gov.uk/Topics/Built-Environment/Housing/16342/shqs/AppendixB

⁴⁷ Rates of fuel poverty are of course not directly observed. They are estimated from data on household income, housing characteristics and fuel prices assuming a given energy consumption regime. We use the terms 'observed' and 'predicted' here to differentiate between these estimates which are based on actual data and estimates where data about at least one set of factors have been simulated.

⁴⁸ We experimented with an alternative method which took the residual from removing the income effect from the joint offsetting effect of income and stock. This gave a slightly lower figure which is to be expected given this method is more conservative in terms of the estimate of the role of housing characteristics and energy efficiency in particular, because where households potentially benefit from both income growth and energy efficiency improvements to move out of fuel poverty, these benefits are already accounted for by income.
