Converting English Housing Survey Data for Use in Energy Models
February 2012: Before data from the English Housing Survey can be used in a SAP‐based model like the Cambridge Housing Model (CHM), it has to be both cleaned and converted to align it with the inputs needed for SAP. A sequence of conversions is needed, and this document summarises an approach to such conversions.This document is necessarily detailed and technical. It will interest readers who have themselves worked with the EHS to do stock modelling work. Other people may be more interested in the outcomes of this modelling work, including Energy Consumption in the UK. Download report here.
Latest Fuel Poverty Updates for London
February 2012: National Energy Action (NEA) have just published their latest estimates of fuel poverty across the UK, which include regional breakdowns. The briefing document (link here; document here) reports that:
- There are an estimated 6.6 million UK households live in fuel poverty
- By October 2011 all six major suppliers had raised their energy prices adding approximately £300 onto the average household energy bill
- Last winter brought an estimated 25,400 excess winter deaths (page 13 of the paper)
- Of which provisional figures estimate that 2,500 deaths were in London
- There has been an increase in the number of fuel poor households in London from 401,859 (13.3%) in 2009 to 564,691 (18.6%) in 2011 (page 15 of the paper)
Local authority action for energy efficiency in housing stock
25 January 2012: This paper presents the findings of analysis of energy efficiency data supplied by landlords with bids for funding from the Decent Homes Standard Backlog programme administered by the Homes and Communities Agency (HCA).

Latest FIT statistics for London
9 January 2012: Ofgem have just produced their latest quarterly detailed spreadsheet providing data on FIT installations across the UK. The spreadsheet now documents information on an impressive 147,114 entries of schemes installed across the UK since the beginning of the scheme!
Filtering the Ofgem spreadsheet to provide London-only data highlights that:
- 4,053 FIT schemes are installed in London as at 31 December 2011 (2.75% of the total UK schemes installed)
- These represent a total of 11.2 MW of electricity capacity installed
Additionally – the latest update on the number of photovoltaics (PVs) installed nationally (a regional breakdown not provided) is available via DECC’s weeks PV statistics (dated 5 January 2012). The 16 December deadline date set by Government – after which installations would face a major reduction in the subsidy support from the FIT mechanism – clearly had a dramatic effect as the graph from the statistics illustrates:
Major London Renewable Energy Study Published
January 2012: As part of a series of DECC-funded regional renewable energy (RE) assessments, the GLA have just published a detailed study on the potential for renewable and low carbon energy in Greater London.
The report sets out results using DECC’s standardised renewable energy assessment methodology but has also developed second tailored methodology to take into account the highly urbanised nature of London, looking at opportunities to reduce CO2 emissions utilising low-carbon decentralised energy (DE) systems such as gas-fired combined heat and power (CHP) and the use of waste heat from power stations. The tailored methodology also gives significantly greater estimates of the technical potential for certain types of RE than the DECC methodology, such as commercial scale wind turbines and photovoltaics but – importantly – the greater use of DE displaces “80% of the thermal microgeneration RE sources… based on the assumption that policies which strongly favour DE over other energy sources are required to reach high levels of heat network deployment.”
The results of this study suggest that:
- Under the DECC methodology, up to 12% and 57% of London’s consumption of electricity and heating respectively can technically be met by RE sources from within Greater London
- However the tailored methodology- for reasons detailed above – estimates RE sources can technically supply up to 34% and 49% of electricity and heating respectively (the lower RE heating figure arising out the increased use of low carbon DE heat displacing some RE heating technologies in the ‘tailored’ methodology).
- The combined technical potential for RE and DE is up to 53% and 44% of London’s consumption of electricity and heating respectively.
- The technical potential of DE using large-scale heat networks is 20% of London’s energy supply
- It is estimated that around 450MW of waste heat capacity is available from existing power stations and energy from waste (EfW) plants in the London area
The London Decentralised Energy Capacity Study can be downloaded here and comprises three reports:
- Phase 1: Technical Assessment
- Phase 2: Deployment Potential
- Phase 3: Roadmap to Deployment
Some significant datasets lie behind the study and can be downloaded from the London Datastore here.

Sub-regional fuel poverty data for England, 2009
DECC 2011: DECC’s latest issue of Energy Trends includes an article on Sub-regional fuel poverty data for England, 2009. Estimates of fuel poverty at the local authority level were published by DECC last month and can be downloaded as an Excel spreadsheet here.

London housing market report Q3 2011
25 November 2011: Interesting data on key economic metrics for London as well as data in relation to housing growth in the capital. The GLA Housing Team briefing can be viewed here.
What are the social impacts of climate change in the UK?
24 November 2011: Joseph Rowntree Foundation (JRF) commissioned research, published today, which highlights that the people who emit the least carbon in the UK are most likely to suffer from the consequences of climate change.
The report – The distribution of UK household CO2 emissions – “provides the first integrated dataset of household emissions and confirms the direct relationship between household income and carbon emissions – the top 10 per cent earners emit more than twice as much carbon as the lowest 10 per cent.”
A second report – ‘Climate change, justice and vulnerability‘ – states that “The most socially vulnerable neighbourhoods in the UK tend to be in urban or coastal locations. There is a North-South divide in extreme socially derived flood-vulnerability in England, while nearly a quarter of London neighbourhoods are classed as extremely socially heat-vulnerable.“

Local Authority Interactive Maps for Insulation, PVs, and Fuel Poverty
24 November 2011: Press notice from DECC today announcing that “As part of the Government’s commitment to be open and accountable to the public and to support local authorities and other users in understanding and comparing data, DECC has today released:
- a series of interactive maps that show trends in local authority data
- sub-regional fuel poverty statistics for England in 2009
This release, combined with the launch on Thursday 27 October 2011 of a sub-national energy consumption analytical tool, aims to aid users in comparing energy data between areas and over time.”
The four datasets covered by this new mapping tool are:
- Cavity wall and loft insulation
- Fuel poverty
- Domestic solar photovoltaic installations
- Gas and electricity consumption

Hills Report Data on Number of Fuel Poor in London
November 2011: The consultation period on the interim report by the Hills Fuel Poverty Review has just closed (Nov 18), but an Excel spreadsheet containing the background data to the report has recently been released.
The spreadsheet tab (Fig B.7 & Table B.4) provides estimates of how the number of households in London would be classed as fuel poor depending on how the definition was set. Hence, under the current definition, 402,000 households in London are fuel poor: if the ‘After Housing Costs’ definition was instead adopted, this number would rise to 584,000. See previous posts on some of the background to this (here and here).
DECC list of Energy Data Resources
November 2011: DECC have just posted a “List of datasets that contain information on energy generation, transport, area wide emissions and buildings at UK and regional/local level”. This is an EXCELLENT and comprehensive list of links to energy data ranging from heat maps, decentralised energy plant, energy consumption data and lots of transport related statistics. A really valuable spreadsheet resource worth downloading. In case link doesn’t work in the future – the document can also be downloaded here.
