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

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

EFG is a SAP of 54 or below

+ boiler ID = 92%

+ wall data = 93%

+ roof data = 98%
