“The greatest direct climate change-related threats for the UK are large increases in flood risk and exposure to high temperatures and heatwaves, shortages in water, substantial risks to UK wildlife and natural ecosystems, risks to domestic and international food production and trade, and from new and emerging pests and diseases.”
DECC (now BEIS) published the latest National Energy Efficiency Data-Framework (NEED) report on 30 June 2016.
NEED provides an “analysis of domestic gas and electricity consumption in 2014 by property attribute, household characteristics, geography and socio-demographic classification, and an analysis of the impact of installing energy efficiency measures in 2013 on a household’s gas consumption.”
The method used [to ascertain the impact of energy efficiency measures] ”compares the gas consumption in properties before and after an energy efficiency measure is installed, with the change in consumption, over the same period, for similar properties which have not had a measure installed.” All results are for annual consumption based on a representative sample of approximately four million properties for England and Wales, unless stated.
Useful information and data in the report (please refer directly to the source material for further context, assumptions and explanations):
- “Estimates of the impact of installing an energy efficiency measure on a household’s gas consumption continue to show that considerable savings can be made by properties installing a single energy efficiency measure, or a combination (for example cavity wall insulation and loft insulation).”
- “In 2014, the median [annual] gas consumption for all properties in the sample was 12,000 kWh, with median electricity consumption at 3,300 kWh.”
- “In 2014, a detached house typically consumed 4,300 kWh of electricity and 17,100 kWh of gas, which equates to a consumption percentage difference of 161 per cent more gas and 74 per cent more electricity than a purpose-built flat in 2014.”
- “In 2014 typical gas consumption for flats was 36 per cent lower than in 2005, but for detached dwellings this reduction was only 26 per cent.”
- “Analysis [of] factors that can predict domestic gas consumption, combining NEED with data from the English Housing Survey and from DECC’s Fuel Poverty analysis…shows that building and demographic characteristics accounted for 44 per cent of the variance in gas consumption.” (Source given – Annex C of the NEED report)
- In 2013 ”typical [median gas consumption] savings for properties installing cavity wall insulation were 8.4 per cent (representing a saving of 1,200 kWh).”
- For the same year, typical savings from “loft insulation [were] 2.1 per cent (300 kWh)…from condensing boilers [savings were] 8.3 per cent (1,200 kWh), and…from solid wall insulation [savings were] 15.5 per cent (2,000 kWh).
- “In all but two [of the packages of measures analysed]…the savings from installing the measures in combination are slightly higher than the sum of the savings for each individual measure.”
- “The energy efficiency of the housing stock has improved between 2005 and 2014. The average SAP rating of a dwelling increased by 9.5 points from 49.0 in 2005 to 58.5 in 2012. (Source given – English Housing Survey Headline Report 2012-13, Annex Table 19)
- Annex G provides a summary of Building Regulations relating to loft insulation, wall insulation, boiler standards and heating controls.
Sustainable Homes published their “Touching the Voids: The impact of energy efficiency on social landlord income and business plans” report on 29 June 2016. The report explores the relationship between good energy efficiency in homes, rent arrears and void rates. They said:
“The boost to [housing association] landlords’ bottom lines from more energy efficient homes could be significant – with potential for a 10,000 home provider to save over £2.4 million if they upgraded their stock from an average SAP 65 to SAP 75.”

The report reflects the views of 438 members of the Energy Institute on the “future challenges and prospects for the energy industry”.
The Institute’s members flagged the lack of energy policy continuity as the biggest challenge facing the industry, with the Government’s energy policy “reset” in November 2015 having yet to “reset confidence” among energy sector professionals. Low oil prices are also flagged as being of significant concern, “stifling growth in the low carbon economy and reducing the imperative for energy efficiency”, and ultimately threatening climate change goals. The report highlights that, in terms of driving progress, energy efficiency has the “greatest scope for improvement within the built environment, specifically through retrofitting the building fabric”.
The project team also took the opportunity to ask their members about the potential effects on the energy sector if the UK were to leave the European Union. An “overwhelming majority of contributors to the Barometer foresee negative effects on the UK energy system” if this were to happen. Negative impacts were anticipated on “securing energy supplies, renewable energy development, climate change and sustainability, and air quality”.
The full report describes the top ten challenges for the sector identified by the survey.

The report presents the results of independent monitoring of ECO2 measures for July 2015 to September 2015 (Quarter 2).
Suppliers conduct three types of monitoring: Technical Monitoring, Score Monitoring and Best Practice Monitoring. Technical Monitoring and Score Monitoring are requirements in the ECO guidance, whereas Best Practice Monitoring is optional.
In terms of technical monitoring, Ofgem states this is to “ensure that measures delivered under ECO are installed to the appropriate standards and are capable of generating the claimed carbon or cost savings.”
“Technical monitoring was carried out on 8,290 measures, amounting to 9% of all measures that fall within the technical monitoring requirement for the quarter (91,823)…Five hundred and fifty three of the 8,290 measures monitored failed to comply with a standard of installation of the measure (~6%).” Some of the most common reasons are set out in the report, and the jobs are placed on a Pathway to Compliance.
