appendices: I. trading and governance structures These lists
include issues to consider:
Trading structures summary These trading structures have varying
attributes such as asset locks, stability of rules, oversight, tax
liabilities and who is in ultimate control.
1. Trust
3. Charitable Incorporated Organisation (a form of charity)
4. Community Interest Company
7. Public limited company
2,3 and 5 can be charitable. 2,4,5,6 can all be co-operatives or
mutuals
A summary of the advantages of each type can be found here :

Governance structures decision matrix In most cases how you want to
govern can be applied to most of these structures.
Do you want a membership?
Does it want to be in full control or be part of a constituency
arrangement with sectoral interests proportionally
represented?
Does the management body - board or committee want similar
proportional representation of different interests?
Is the board professional or voluntary or both? How is it
resourced? Is there a parallel professional executive team?
Are all interests in the operation deemed potentially conflicting
or is there a means to ascertain whether they can be elided in a
more co-operative or partnership approach?
Decisions on these can only be made once the nature of activities
has been at least roughly decided on. If all light touch then much
of the management can be done using existing public sector
management approaches with contracts with private ventures managed
against KPI’s and appropriate sanction or break clauses.

II. modelling and pathways The brief was for a pathway to zero
carbon by 2038 so in some cases these figures divert from those in
the regional pathway report as those do not get to zero.1
These are high level figures using national averages, regional
where available. They only assume current technology, it is almost
certain that others will become available over the coming years.
The assumptions table on the next page sets out some key
assumptions and compares carbon emissions for an average property
at current average EPC and those of a typical property retrofitted
to the 2030 target of EPC of C. The second table sets out
assumptions on renewables.
It should be noted that EPC software uses a higher carbon intensity
figure than is the current grid average, which causes some
discrepancies with future figures. To reduce chance of
overestimation we have used the value in the consultation version
of SAP10.
For the graphs we have used BEIS figures for average energy
consumption and carbon intensity is modelled down to zero by
2038.
The retrofit deployment figures aim to get to 80,000 properties per
year in 7-8 years, allowing time for the creation of a sufficiently
sized skilled workforce, a multiplication of current manufacturing
capacity and development of the other components.
Fig A2.1 shows the modelled CO emissions reduction from retrofit
compared to one that reduces the current emissions of housing by
14.5% a year, as shown by the Tyndall Centre to enable the region
to keep within its CO budget. So while both meet the zero by 2038
target there is a large divergence in trajectory which will lead to
greater total CO emissions over the 18 years. Total CO emissions
over the 18 years are around twice those available in the carbon
budget if shared equally across sectors, which can be seen from the
area under the lines.
The retrofits per year are the same profile in each scenario. Fig
A2.2 shows the retrofit trajectory with a rapid deployment of the
PV element of the whole house retrofits in advance of the main bulk
of demand reduction retrofit work. Fig A2.3 models CO emissions
with that advance deployment which goes someway to closing the gap
between the two trajectories - from around 18MTCO to just under
6MTCO over the total carbon emissions budget.
For the amount of PV to be viable it needs to be supported with
storage. This can be house by house as well as at neighbourhood and
utility scale. This enables

further incomes as well as CO savings to be derived from in house
demand shifting and peak energy sales, while also contributing to
Demand Side Reduction (DSR) and Frequency Response services at the
larger scale. A conservative view has been taken of related CO
savings; further research is required as these could be
higher.
Solar Panels capacity check It is beyond the scope of this report
but as the solar PV outputs are crucial to the viability of the
modelling, an exercise was carried out to check that there would be
enough space to put the total amount of solar panels suggested.
Rooftops were measured for three typical residential areas in the
region, detailed in the table below. The conclusion is that for
most of the homes it would be possible to fit enough solar panels
but other rooftops would have to be used, such as public buildings
or offices, with delivery vehicles developed to enable this. The
modelling does not include additional free standing structures
purpose built for PV, leading us to conclude that the total solar
panels figure used in the main model is feasible.

III. retrofit measures - getting to EPCs C & A The level of
retrofit needed has a fundamental effect on the model proposed to
deliver it.
Getting a house to a C involves works like:
• loft top up to 250mm
• draught strips on windows and external doors
• double glazing
• boiler change
• wall insulation - most easily filled cavities have been insulated
so this is either internal or external wall insulation, but the
demand reductions required to get to C mean this is usually 60-90mm
of EPS
There is a perception that these measures pose few risks to the
property so schemes are often carried out with no design. This has
meant that measures can go straight to contractors and have tended
to be assessed by numbers installed rather than the effect on the
property.
PAS2035 requires retrofits are designed and assessed for risk. This
makes the paradigm shift to whole house retrofit easier as it
assists in making it look more worthwhile to those sceptical.
Getting a house to above A
achieving net zero carbon involves a whole house retrofit, typical
works include:
• loft top up to 400mm
• airtightness works
• air source heat pump
• wall insulation to achieve near double the performance of getting
to C, with cold bridges addressed
• floor insulation
• managed ventilation
• solar panels and energy storage
This kind of suite of measures needs to be properly designed. While
much can be standardised, a level of expertise is needed to
identify what can be the subject of a standard solution, and which.
Contractors need to understand new principles such as air-tightness
ad cold bridges which have a much larger effect as energy demand
reduces.

The needs of whole house fit into the PAS2035 model and more
standardised data should be forthcoming making assessment of
progress against target across the region easier to achieve along
with the concomitant planning that can go with it.
Getting from C to A Retrofits planned to achieve an EPC of C need
to be designed in such a way that a further visit can take place
that take the property to the longer term target.
If double glazing, thin wall insulation and a new gas boiler are
fitted to meet the EPC target, these would have to removed and
replaced with triple glazing, higher performance wall insulation
and an air source heat pump to get to zero carbon : this would be a
huge waste of money and effort and would probably mean that
property is stuck at EPC C for a decade or more until things start
to need replacing.
Achieving good air-tightness and cold bridging requires attention
to every feasible junction in the property. Retrofits fail to meet
expected energy use reductions if cold air is leaking around the
edge of every area of work. The junctions are much more accessible
while retrofit are taking place, so this work would be better
carried out in the first visit taking properties to C. Given the
difference in trades this may be difficult.
Whole House Plans prepared for homes now should be done with the
higher performance target in mind. If the work budget is less than
the total cost, measures can be chosen which minimise abortive work
or costly extra visits : “No Regrets measures”.

SCALING UP BETTER HOMES YORKSHIRE
Workshop summary 5 October 2020
Breakout #1 Retrofit Hub The group did not disagree with the
recommendations, but they did suggest areas for more attention. For
example:
a) Experience of local delivery varied across the Leeds City Region
and partnerships were felt to work better for the larger
metropolitan areas, particularly where large stockholders can exert
leverage.
b) Lots of information in report bit overwhelming 3 different
markets, owner occupiers very dispersed so how can they be
reached?
c) Behaviour change is important and needs to be seen not only from
home- owners viewpoint, but also from those they most interact with
for example banks, small builders and merchants.
d) Suggest a one stop shop approach that includes finance options
and ensure the means motive and opportunity are considered for
every referral.
e) The report talks about customer journey and one stop shop
models, the recommendations will not directly progress provision of
trusted advice and support. Does this approach need to be more
explicit?
f) Suggestion to talk to the CAB and Warmworks (Scotland) about
providing hub advice.
g) The latter Hub model exists in Scotland though the EST advice
centre model. The customer journey process is triaged from national
to local, sign posting customers to LA schemes and EST loans &
finance. This could be adopted at English regional level
h) The additional costs of design monitoring communication need to
be considered. Is the Hub picking up these costs?
i) How detailed should data be? It needs to be included in business
model. The on-costs can be expensive so collecting data needs to
get cheaper. E.g. heat meter costs a lot of money.
The group did not openly disagree with the recommendations
therefore the Community of Interest will need to address the above
if they are to implement a successful Retrofit Hub model.
Breakout #2 ways of paying for retrofit The group were not fully
convinced that provision of low-cost loans would be enough to
persuade homeowners to retrofit their homes. The overwhelming sense
from the group was that a regional loan fund wouldn’t work.
However, they did agree that low interest rates would be important,
while they added that perception of what is low is will differ.
They cited that in Germany you can borrow at 1% whereas in UK it
can be 10%.
Sarah Hughes
Appendix V : Workshop Summary
There was general agreement for more regulation for example,
Government action on EPC standards as well as (local?) incentives.
However the group did not specify a who they might apply to, or
thorough what mechanisms.
They suggested that borrowing need to be flexible; between 5 and 20
years depending on the customers. Therefore, the capital must be
patient. Also need funding products that address the imbalance
between the length of loans and the average length of home
ownership.
The group thought that those who are able could borrow more
cheaply, perhaps up to £20,000. Yet they agreed that such
propositions compete with other priorities for their borrowing such
as kitchens and bathrooms. Whereas they thought that those unable
to borrow would need a grant.
They suggested that loans will not be suitable for the most
vulnerable occupants with limited income. Experience of offering
interest free loans for energy efficiency improvements and had a
very low take up from Local Authorities. Whereas, equity- based
loans have a greater take up, although there remain barriers for
vulnerable people.
Not all local authorities favoured provision of equity-based
lending and secured loans. It was suggested that financial
decisions like this will be sensitive to Local Authority budgets
and the level of debt. If they require use of public loan board,
then they might need a way to take the debt off the books/ balance
sheet. They also reflected that State Aid is a key consideration
for them. There was however agreement that private funds were
important including Municipal Bonds to capitalise the loan
fund.
In general, the group thought that more support was needed to
support the private rented sector.
The corresponding need to educate people about the benefits,
particularly the effect on health, of doing the work and how a loan
would work was highlighted. Especially as the length of time with
limited early benefits will put off people if there is nothing in
it for them.
There was a reflection that options should be equitable and
accessible to all sections of society not just middle-class able to
pay.
Additional revenues
There was support for community solar and battery solutions to
deliver local benefits and use of local renewable energy. But the
group thought that Individual houses don’t stack up socially,
politically, economically or from an efficiency perspective. There
were also concerned about the environmental sustainability of
supply chains.
There was some scepticism on the accessibility and scalability of
the aggregation model owing to the early stages of this market. And
confusion over precisely who will be accessing the revenues and how
they would assist with the loan arrangements.
Breakout #3 Pipeline • Broadly agreed with the recommendations. •
Suggested we should engage with the DNO as their views should be
reflected
on and integrated at an early stage. Particularly with the
challenges faced with scaling up on the number of property owners
to engage with.
• Prioritisation of the recommendations and the need to try and
understand which would make the greatest progress as quickly as
possible to help make the scaling up easier eg have a retrofit
structure that enabled all the players to communicate effectively,
and set regional quality standards that can then de- risk the
availability of finance
• Concern around the need for proper software for DPS. Should not
underestimate/ emphasise the scale of software needed that would
encourage software providers involvement. We should utilise
existing infrastructure
• Key point was to establish the community of interest, share
knowledge and facilitate.
• Sometimes larger companies are more ideally placed to carry out
the works and other times smaller businesses
• needed to be more flexibility in the approach adopted. For
example sometimes larger companies are more ideally placed to carry
out the works and other times smaller businesses - different area
may need different approaches eg in certain circumstances a large
contractor or social housing provided could be ideal to deliver. In
other smaller scale projects the delivery may require a more
bespoke approach around coercion and coalition working, quality
assurance arrangements and financing to support SMEs on the
learning curve.
• Need to be clearer on how to fund projects without government
assistance – what else is available and replicable
nationally?
Breakout #4 Workforce and skills There were no objections to the
recommendation but guidance on principals for training and the
necessary provisions were put forward.
For example, in terms of the courses, students must have the clear
line of sight to jobs. Moreover, they suggested that the training
must be worthwhile in terms of workers own finances and the route
for career progression.
They identified need for skilled trainers and how difficult it
could be to recruit the specialists. They pointed the need for
facilities and capacity to provide the courses.
The group simultaneously thought that industry was over-reliant on
knowledge of the manufacturers, while suggesting they were a key
driver of quality installations.
The group suggested additional training needs for families and
occupants so they can adapt to retrofit measures and adjust their
behaviour.

READING Reinventing retrofit How to scale up home energy efficiency
in the UK
Report This report examines how the Energiesprong approach could be
scaled up to help meet the UK’s legally binding carbon emission
reductions.
Reducing disturbance to occupants. Providing certainty of
expenditure to heat the home through the 'comfort plan'.
New finance model to secure return on investment together with
innovation in warranties and guarantees, new form of procurement
for outcomes.
The Energiesprong approach could contribute to solving one of the
UK’s major energy challenges by: • using new technology to
permanently lower the cost of retrofits, removing the need for
subsidies; • providing a low hassle option for householders:
retrofits by this method can be installed in as little as a day; •
offering a large scale heat solution for the UK; • stimulating
innovation in the construction sector to raise productivity.

Warm Homes Save Lives establishing region wide scaling up of
retrofit, whole house retrofit plans, targeting the most vulnerable
with public funding
at the centre of the programme critical building block both to be
established to be established identification of a new approach to
addressing fuel poverty through a person centred focus with
regional scale oversight, support and recognition of multiple entry
points for support and multiple delivery routes.
2020 Formed the basis of a £100 proposal to government to support
establishment of the bulding blocks
the innovative element of the proposal was ensuring the person
living in fuel poverty is at the centre of decisionmaking. this
therefore moves the agenda beyond retrofit but must respond to the
need for a whole house retrofit plan within which emergency fuel
poverty actions sit. Less expensive to administer than ECO with
hugely improved outcomes by allowing discretion on grant levels and
what they fund.

The customer journey through the Green Deal has to be carefully
thought through. The journey must be short and consideration taken
of any barriers to the market place; such as price, acceptance and
concerns regarding quality.
Many Local Authorities had committed to considerable preparatory
work before the bid winners were announced and found that this was
of immense assistance given the tight timetable.
It has been suggested that the Green Deal could have a
pre-assessment stage to screen out those homes where the Green Deal
would not be suitable. The customer would be disappointed if the
report showed that nothing could be done after a payment had been
made. A free assessment or a pre-assessment stage would be useful
to remove an obstacle to the Green Deal. Supply chain engagmeent

Scaling up retrofit 2050
High level report – some good case studies (section 4) – generally
quite generic – worth a quick skim
Engage with the consumers by identifying the best ways to discuss
the benefits of deep retrofit with householders, and developing
trusted intermediaries to be a single point of contact for owners
and tenants.
Encourage investment by aggregating projects in large blocks to
attract investors and reduce costs while introducing more flexible
ways for local authorities to borrow and invest in retrofit
programmes. There needs to be more revenue-neutral methods of
incentivising deep retrofit, more assistance for registered social
landlords (RSLs) to develop long-term financial plans and more
learning from investment approaches used for other forms of
national infrastructure.
Recommendations 1. Establishing a long-term plan Reducing costs and
building supply chain capacity by developing pilot projects and
demonstrators as well as a plan to bring the cost per property to
below 30- year repair, maintenance and refurbishment budgets.
To evidence why Why a nationwide programme to upgrade the existing
housing stock is the only way for the UK to achieve its carbon
saving goals.
To meet the UK’s climate change targets, we will need to improve
nearly every home in the UK with energy efficiency measures at a
rate of more than 1.5 homes every minute between now and 2050. And
that is only if we visit every home once, with a single ‘whole
house’ renovation rather than incremental improvements. Right now,
we are falling far short in both the rates and depths of
interventions.

Dartford Housing Retrofit Project Evaluation Report 2017
Small sample study of retrofit homes using different approaches (5
houses) – worth a very quick skim
The responses from the occupants indicated that they were generally
very happy with the improvement to their houses after the retrofit
works were undertaken, in terms of comfort and the appearance of
their property.
2014-2016 The data presented in this report shows that significant
benefits, in terms of comfort, bills and CO2 emissions were seen by
the four households studied in detail, which suggests the project
as a whole was successful in delivering good quality retrofits to
hard-to-treat properties which delivered real results while
maintaining quality and avoiding adverse consequences associated
with poorly-fitted
retrofits.https://assets.publishing.service.gov.uk/

Leeds Core cities Green Deal monitoring projectMoniotring of 47
properties – general performance of retrofit in BEIS/ DECC
programme – good data and interpretation
The surveys revealed that the ‘whole house approach’ to retrofit
was, more often, missing, and quality assurance around insulation
detailing was regularly absent, leading to avoidable errors and
potentially embedding problems in the installations. Furthermore,
moisture issues were, in the majority of instances, over-looked or
made worse despite over half the sample having some form of damp.
Despite this, energy savings were observed and the appearance of
the dwellings were improved, thus apparent satisfaction was
generally high, even though the installs were imperfect and
moisture problems were
introducedhttps://assets.publishing.service.gov.uk/

huge benefits to be derived from the use of Show Homes to promote
energy savings through retrofit and renovation. These benefits are
felt throughout the supply chain, by Government, the consumer and
the population as a whole: · Supply chains benefit by raising
awareness of their products and services. · Government benefits by
awareness-raising and increasing the uptake of energy efficiency
measures, and more generally helping to reduce carbon emissions
enabling it to meet its legally binding targets. This last point
benefits us all. · Consumers benefit by being better informed about
products, services, benefits and drawbacks of energy efficiency and
renewable energy measures.

Better Homes, Better Wales, Better World Decarbonising existing
homes in Wales 2019
Report to Welsh Ministers from the Decarbonisation of Homes in
Wales Advisory Group We sought expert guidance on creating the
necessary conditions for success from experts at the Centre for
Behaviour Change at University College London
In making its recommendations, the Advisory Group has considered
the likely costs of implementation against the benefits that will
flow from it. We strongly believe that, in the context of the
Well-being Goals, the benefits will substantially outweigh the
costs.
Summary of Recommendations 1. Political parties in Wales should
make a strategic commitment to national residential decarbonisation
and stick to it 2. The Welsh Government should set ambitious
housing targets to meet its ambition of achieving net zero carbon
by 2050 3. The Welsh Government should put in place the right
quality system and delivery mechanisms across all tenures to help
achieve the targets 4. The Welsh Government, working with others,
should develop a holistic package of support across all tenures to
motivate and facilitate action 5. The Welsh Government should
collect data about the status and condition of the housing stock to
inform future decisions and measure progress towards targets 6. The
Welsh Government should continue to monitor and test new solutions
to decarbonise homes 7. The Welsh Government and its partners
should make maximum use of communities, networks, associations and
Third Sector organisations in helping to decarbonise homes

Overcoming the systemic challenges of retrofitting residential
buildings in the United Kingdom A Herculean task? 2018
In many ways, overcoming the ‘multi-headed- challenges’ of
achieving widespread energy efficiency (EE) retrofit is an equally
Herculean task. Policy initiatives in the UK, such as the Energy
Companies Obligation (ECO) and the Green Deal, have sought and
failed to achieve the mass uptake of residential retrofit.
policies have failed to address four systemic challenges that
constrain uptake for whole house retrofits, and that a more
comprehensive and widereaching policy approach will be needed to
overcome each of these challenges. The chapter is therefore focused
on some of the solutions to these challenges from the perspective
of three key elements of a retrofit: the business model, financing
and intermediaries. It also discusses the ways in which policy
could support these outcomes.

remote monitoring - early warning Remote track Monitoring is an
innovative monitoring technique that can be used to assess track
quality determining if the track is deteriorating. The same process
can be used to understand if structures have moved due to work
activities nearby. Remote monitoring is used on a large number of
projects and has been used to great effect on the Crossrail
project. Due to the large scale excavation works the surrounding
infrastructure require monitoring as this could create structural
failure or/and effect the alignment of track
