ECO 1 & 2 and transition to Fuel Poverty Obligation
What is ECO
Energy Companies Obligation
A Government energy efficiency scheme to help reduce carbon emissions and reduce fuel poverty
Administered by Ofgem
ECO 1 – January 2013 to March 2015
ECO 2 – April 2015 to March 2017
ECO Obligations
ECO currently has 3 Obligations (strands):
1. CERO – Carbon Emissions Reduction Obligation
2. CSCO – Carbon Saving Community Obligation
3. HHCRO – Home Heating Cost Reduction Obligation
Purpose of the change
Targeting
Simplifying
Learning from previous schemes
Continuity
ECO Transition
ECO 2 transition and FPO
Will run from April 2017
More focus on insulation –less boilers
Social housing now eligible for affordable warmth funding –for transitional period only …
Deemed scores
Deemed scores
ECO currently uses an EPC (full RdSAP dataset) for scoring
Deemed scores is a table of pre-calculated scores dependent on:
Property type (semi-detached, flat etc)
Property size (number of bedrooms)
Heating system
Measure type
Deemed scores
Deemed scores
BIG house = BIG Deemed Score
Deemed scores
SMALL house = SMALL Deemed Score
But...
Masses of loft insulation
Well insulated walls and floors
Efficient glazing and doors
But...
No loft insulation
Old solid brick walls, no floor or wall insulation
Single glazing
Deemed scores
Current ECO – smaller uninsulated house would get a bigger ECO score for a boiler
Deemed scores – larger well insulated house would get the bigger score for a boiler
So ‘Granny’ alone in the small house stays cold and unable to afford to heat her house
ECO 2 transition and
Social Housing
Social Housing
Only dwellings with a SAP rating of E, F or G are eligible (SAP 54 or below)
Insulation measures or ‘new central heating installs’
How can you find E, F, G’s ?

Opportunities
Asset management systems are likely to hold data on wall type and heating fuel
About 5% of properties in our EPC database have solid walls + no mains gas
Potential to either improve data quality or consider plans for properties with ECO potential

What about bands?
EFG is a SAP of 54 or below
Just minimum data set91% of G rated in AAPro would be E,F or G in full RdSAP
+ boiler ID = 92%
+ wall data = 93%
+ roof data = 98%
