description: &lt;p&gt;The &lt;i&gt;English Housing Survey&lt;/i&gt; (EHS) is a continuous national survey commissioned by the Ministry of Housing, Community and Local Government (MHCLG) that collects information about people's housing circumstances and the condition and energy efficiency of housing in England. The EHS brings together two previous survey series into a single fieldwork operation: the &lt;i&gt;English House Condition Survey&lt;/i&gt; (EHCS) (available from the UK Data Archive under GN 33158) and the &lt;i&gt;Survey of English Housing&lt;/i&gt; (SEH) (available under GN 33277). The EHS covers all housing tenures. The information obtained through the survey provides an accurate picture of people living in the dwelling, and their views on housing and their neighbourhoods. The survey is also used to inform the development and monitoring of the Ministry's housing policies. Results from the survey are also used by a wide range of other users including other government departments, local authorities, housing associations, landlords, academics, construction industry professionals, consultants, and the general public.&lt;/p&gt;&lt;p&gt;
The EHS has a complex multi-stage methodology consisting of two main elements; an initial interview survey of around 12,000 households and a follow-up physical inspection. Some further elements are also periodically included in or derived from the EHS: for 2008 and 2009, a desk-based market valuation was conducted of a sub-sample of 8,000 dwellings (including vacant ones), but this was not carried out from 2010 onwards. A periodic follow-up survey of private landlords and agents (the &lt;i&gt;Private Landlords Survey&lt;/i&gt; (PLS)) is conducted using information from the EHS interview survey. Fuel Poverty datasets are also available from 2003, created by the Department for Energy and Climate Change (DECC).&lt;br&gt;
&lt;br&gt;
The EHS interview survey sample formed part of the Integrated Household Survey (IHS) (available from the Archive under GN 33420) from April 2008 to April 2011. During this period the core questions from the IHS formed part of the EHS questionnaire.&lt;br&gt;
&lt;br&gt;
&lt;i&gt;Safeguarded and Special Licence Versions:&lt;/i&gt;&lt;br&gt;
From 2014 data onwards, the Safeguarded versions (previously known as End User Licence (EUL)) of the EHS will only include derived variables. In addition the number of variables on the new EUL datasets has been reduced and disclosure control increased on certain remaining variables. New Special Licence versions of the EHS will be deposited later in the year, which will be of a similar nature to previous EHS EUL datasets and will include derived and raw datasets.&lt;/p&gt;&lt;p&gt;
&lt;br&gt;

&lt;/p&gt; The &lt;i&gt;Energy Follow Up Survey, 2011&lt;/i&gt; (EFUS 2011) aims to provide detailed, up to date information on patterns of household and dwelling energy use. Within this survey, householders are asked questions about the type and usage patterns of the main and secondary heating systems in their homes, the water heating system and usage, dwelling insulation, lighting indoor temperatures and the use of appliances. &lt;br&gt;
&lt;br&gt;
The EFUS 2011 is a follow up interview survey of a subset of households first visited as part of the &lt;i&gt; English Housing Survey, 2010-2011: Household Data&lt;/i&gt; (EHS) (available from the UK Data Archive under SN 7040). It is possible to link the EFUS 2011 data to the EHS data by applying for access to SN 7883 - &lt;I&gt;Energy Follow Up Survey, 2011: Lookup File: Secure Access&lt;/I&gt;. This study is subject to further access restrictions (see the &lt;a class="external" href="https://www.ukdataservice.ac.uk/get-data/how-to-access/accesssecurelab" title="Secure Lab"&gt;Secure Lab&lt;/a&gt; webpages for details). The last large-scale national survey to consider the detailed use of heating systems and other sources of energy use in homes was the EFUS 1998 (not available from the UK Data Archive).&lt;br&gt;
&lt;br&gt;
An additional sub-sample of these households was selected to have temperature loggers and electricity monitors installed. A further stage of the EFUS involved the collection of gas and electricity consumption data from meter readings. The raw meter readings data were added to the survey in November 2014, in the form of 823 separate Excel files. Previously, the study included only the summary data for the meter readings. For details of the metered energy consumption research, see Report 1: Summary of Findings, in the documentation. &lt;br&gt;
&lt;br&gt;
For the third edition of the study (February 2016), the electricity monitoring data for the 79 households who agreed to have their electricity monitored over the course of 6-12 months (see above) were added to the study. Each subfolder represents the readings from one household (hence 79 subfolders in total). Multiple CSV files are included in the subfolders for each day of reading; the number of files vary, so may not be the same for each household. See the EFUS 2011 Dataset Documentation (p.34) for details.&lt;br&gt;
