ENERGY CONSUMPTION IN HOUSEHOLDS

REVIEW OF CURRENT ACTIVITIES





MEMBER STATE: United Kingdom …………………………………….


Yes No

1. Do you collect data on domestic energy consumption? ● O
1.1 If not, do you plan to start collecting such data? O O


When? ………


2. If you do collect data on domestic energy consumption, do you use:

  • survey(s) ● O

  • administrative sources ● O

  • modelling ● O



PART A: SURVEYS, ADMINISTRATIVE SOURCES
Part A reviews surveys and administrative sources used at national level. It examines the availability of typical information normally made available by such sources (the recommended coverage was used as benchmark), their quality and associated costs.


3. Please, give the name and a short description of each survey and administrative source used (include any planned survey, the description of which is already available). Include information on collected statistics and users at national level. Indicate how this information is used for policy definition / evaluation. Indicate additional priority user requirements and associated statistics which should be made available in future data collections to be carried out in your country.

Aggregate domestic energy consumption (collected as part of the energy balance process) A number of surveys are covered within this overall collection – as separate surveys are used for the different fuel types. The main fuels are gas and electricity – though there is also consumption of coal, petroleum products, wood etc. Details of questionnaires used to compile this data are available from the DECC web site: http://www.decc.gov.uk/en/content/cms/statistics/governance/governance.aspx

English Housing Survey (which from 2008 includes the English House Conditions Survey) – This is a survey which measures the physical condition of the housing stock and the characteristics of households living in this properties. The resulting data provides information on heating systems, water systems and insulation levels. These data feed into the BREDEM/BREHOMES models described in part B. Similar surveys are also run for Scotland and, on a less frequent basis, Wales and Northern Ireland.


Meter point gas and electricity data collection – These data are used for the production of local area energy consumption estimates, and also feed the NEED framework outlined below. Local area data for solid fuels and petroleum products are modelled using greenhouse gas emissions data, no split by end user is available.
National Energy Efficiency Data framework (NEED) – Since 2011, meter point data for individual properties has been matched to data on energy efficiency measures installed in domestic properties (Home Energy Efficiency Database) and data on the characteristics of the dwellings and the households to provide a new source for analysis of UK domestic energy consumption and impact of energy efficiency measures. This source has been used in developing policy for the Green Deal and is planned to be used in a number of policy evaluations.
Energy Performance Certificate (EPC) database – this is not yet in use for work on energy consumption and energy efficiency analysis. However, work is underway for this source to be made available, and under the Green Deal, every property that takes out a Green Deal assessment will have an EPC before and after any installations. This will provide information on the characteristics of the dwelling, any energy efficiency measures installed, a banded SAP rating, and other information which can be analysed to better understand UK domestic energy consumption.

4. For each survey or administrative source identified in section 3, complete the following questions, please:

Estimates of consumption are also temperature and seasonally adjusted and the resulting series is closely examined. Comparisons are also made annually with data from the household expenditure series described elsewhere in this note.

16 Do you apply automated plausibility checks? O ● O

Time series analysis is performed on both the macro data and the micro data with analysis performed on “unusual” data. The trends from the different fuels are also looked at together to see whether the data are presenting a coherent picture of the general trend and to assess levels of fuel switching.

17 Do you use these data for compiling national energy balances? ● O O

18 Do you publish the survey results separately? ● O

If "yes" how do you publish (internet, brochure, CD….) and
when did you publish the most recent figures? Book, with internet version published annually and quarterly. Internet only tables produced monthly.

Link:

Methodology notes are updated on a regular basis and are published on the DECC web site, with separate notes produced for each fuel.

  1. What is the total cost of the survey in Euros?

Around €4million from 2012/13 excluding internal management, analysis and reporting costs

What part of the total cost is attributed to the energy section? Unsure, between 20-50%

7 Describe the main purpose of the collection:

To provide information about the type and condition of property, and enable this to be linked with information about the people that live there, the local neighbourhood, and the market value of the property. This allows a wide range of analysis to provide information on the housing stock, make comparisons and study trends and patterns, and monitor and evaluate the impact of government policies.


The data and findings contribute to the development, evaluation and monitoring of government policy and the allocation of resources. The EHS provides evidence that helps government identify and understand housing issues, investigate possible policy options and their potential effects, and monitor and evaluate policies and initiatives. With regards to energy policy, they are used to calculate statistics on the number of households in fuel poverty and to understand how the energy efficiency of the housing stock is evolving over time. They provide a base point for the calculation of quarterly data on levels of insulation in domestic properties.

8 What is the frequency of the data collection?

Continuous with annual results
