Heading: Consultation on the proposed Social Housing Net Zero Standard
___________________________________________________________________
1. Summary 
1.1 The Social Housing Net Zero Standard (SHNZS) is being introduced by the
Scottish Government to replace the second Energy Efficiency Standard for
Social Housing (EESSH2). 
1.2 The SHNZS is designed to reduce the space heating demand of existing
social housing in Scotland by 2033, and to replace fossil fuel heating systems
with a clean heating alternative, by a backstop of 2045. 
1.3 The reduced space heating demand is proposed at a level of between 120-
71kWh/m2/year, with 70kWh/m2/year or under proposed if fuel poverty is a
particular concern. 120 -71 kWh/m2/year is regarded as the equivalent of an
existing Energy Performance Certificate (EPC) Band C and 70kWm/m2/year
or under the equivalent of an existing EPC Band B. 
1.4 Space heating demand reduction is required to assist with successfully
implementing clean heating systems such as heat pumps, modern storage,
and heat networks. Clean heating fuel (electricity) is currently more expensive
than fossil fuels and there would be a potential to exacerbate fuel poverty if
some space heating demand reduction was not required. 
1.5 The Scottish Government is aiming to finalise the SHNZS later in 2024, with it
being introduced in 2025. The Housing Regulator will incorporate the space
heating demand and targets for clean heating installs, as part of the Annual
Return on the Charter (ARC), and they will engage with social landlords on
the Charter indicators needed for reporting performance against the standard.
It is yet to be determined when it will form part of the ARC.

1.6 Renfrewshire Council is broadly in favour with the proposals as set out in the
consultation.
___________________________________________________________________
2. Recommendations
It is recommended that the Communities and Housing Policy Board:
2.1 Homologates the consultation response submitted by Renfrewshire Council to
the Scottish Government on the 8th March 2024, on the Social Housing Net
Zero Standard, as detailed within Appendix 1 of this report. 
3. Background
3.1 The Scottish Government introduced the first energy efficiency requirements
for social housing in the Scottish Housing Quality Standard (SHQS) of 2015.
Standards of energy efficiency were increased with the Energy Efficiency
Standard for Social Housing (EESSH) of 2020 and then EESSH2 was
implemented with interim 2025 targets and a 2032 completion date. 
3.2 SHQS, EESSH and EESSH2 were all targets based on the energy efficiency
bandings of a domestic Energy Performance Certificate (EPC). EPC’s energy
efficiency bandings are mainly based on a rating system which is a
combination of, The efficiency quality of the construction fabric, heating
system type and the cost of fuel for that heating system. 
3.3 An EPC rating could be improved by replacing a heating system with one that
used cheaper fuel, and during the SHQS implementation period especially,
this resulted in an increased use of natural gas boilers. 
3.4 As burning fossil fuels such as gas, was one of the main drivers for climate
change, it became apparent that for net zero, homes had to be heated with
clean heating alternatives. Clean heating systems such as modern storage,
heat pumps and Heat Networks, use electricity as their fuel. But as electricity
is currently around four times the cost of gas, its use would then lead to EPC
ratings falling and potentially exacerbate fuel poverty. 
3.5 The Scottish Government suspended EESSH2 in 2022 and pledged to look at
a new standard which would address energy efficiency, the need to remove
fossil fuel heating from social housing and take cognisance of fuel poverty.
The Social Housing Net Zero Standard has been proposed to address those
issues. 
3.6 The Scottish Government also recognised that EPCs would need reformed to
ensure they reflected net zero carbon requirements. They proposed to
remove the energy efficiency rating and replace with three separate metrics
rating: 
• Space heating demand of the building (kWh/m2/year and banded A-G)
• The type of heating system (clean heating systems rated highest)
• An energy cost rating (based on £/m2/year, banded A-G)

Page 3

3.7 The Social Housing Net Zero Standard (SHNZS) is the new standard
proposed by the Scottish Government to replace EESSH2. It aligns with the
new metrics proposed in reformed EPCs. The consultation closed in March
2024, and it is expected to be finalised by the Scottish Government later this
year. The standard should be in place for social landlords sometime in 2025,
with timing of reporting on compliance with the standard still to be determined. 
4. The Social Housing Net Zero Standard 
4.1 The SHNZS has two main objectives: 
• To reduce the space heating demand of homes
• To replace fossil fuel heating with clean heating technology 
4.2 The space heating demand is a measure of the amount of heat energy
required to heat a building to a desired temperature and maintain that
temperature inside. This is measured in kWh/m2/year. The lower the figure,
the better. Heating demand is mainly affected by: 
• The type of wall, floor, and roof construction
• The windows and doors
• Insulation levels
• Air tightness (the amount of warm air escaping from a house) 
4.3 The reduced space heating demand is proposed at a level of between 120-
71kWh/m2/year, with 70kWh/m2/year or under proposed if fuel poverty is a
particular concern. 120 -71 kWh/m2/year is regarded as the equivalent of an
existing EPC Band C and 70kWm/m2/year or under the equivalent of an
existing EPC Band B. The proposal is for all social housing stock to achieve
this by 2033. For context, EESSH2 was set as an EPC Band B by 2032.
4.4 Where certain hard to treat housing stock may struggle to meet the limit of
120 kWh/m2/year, it is proposed that they meet a minimum energy efficiency
standard, composed of standard efficiency elements being carried out such
as:
• 270mm loft insulation
• Cavity wall insulation
• Draught proofing
• Heating controls
• 80mm hot water cylinder insulation
• Suspended floor insulation
For Renfrewshire Council housing stock, early indications are that traditional
sandstone tenements and some non-traditional construction homes are the
property types where it will be difficult to cost effectively meet the proposed
SHNZS, however, it is likely to be possible to meet the proposed minimum
energy efficiency standard. It is anticipated that only very low numbers of our
homes may fail to meet the minimum standard.

It is proposed that social rented homes cannot be relet after 2028, if this
minimum standard is not reached.
4.5 Fossil fuel main heating systems are to be replaced by clean heating systems
in order to meet net zero carbon. The backstop date for all heating to be clean
in social housing is 2045. The consultation proposed some milestones
between 2030 and 2045, where a certain percentage of the landlord’s stock is
expected to have clean heating. 
5. Consultation Response
5.1 The consultation response is set out in full at Appendix 1 of this report. 
Renfrewshire Council’s response was submitted on 8th March 2024, the timing
of which meant officers were not able to bring the proposed consultation
response to Policy Board for approval prior to submitting the response.
5.2 The response from Renfrewshire Council is generally supportive of the
proposals, but we did not agree with being unable to let stock that may not
fully meet the minimum standard, citing that other variables need to be
considered (such as demand, desirability of area and homelessness levels).
We also expressed concerns that the upper range of the SHNZS may not be
stringent enough to help tackle fuel poverty and the concept of a just
transition.
5.3 Once the SHNZS is confirmed, our housing asset management strategy will
reflect the new standard and analysis will be carried out to determine the
impact of the SHNZS on future investment programmes. Any funding
implications will need to be considered within the HRA Business Plan and will
be included in future reports to Policy Board.
___________________________________________________________________
Implications of the Report
1. Financial – The implementation of the Social Housing Net Zero Standard
(SHNZS) is expected to lead to increased capital investment in the future. As
a key driver for changes to the HRA Business Plan, the SHNZS will prompt
adjustments in our asset management strategy. An analysis will be conducted
to assess the impact of the SHNZS on future investment programmes. Any
funding implications arising from this standard will be carefully considered
within the HRA Business Plan and will be included in future reports to the
Policy Board. 
2. HR & Organisational Development - None
3. Community/Council Planning – 
• Our Renfrewshire is thriving – improving housing conditions
encouraging people to live in Renfrewshire.
• Our Renfrewshire is well – improving housing conditions benefitting
tenants. Helping to address fuel poverty.

Page 5

• Reshaping our place, our economy, and our future – investment in the
refurbishment of social rented will create jobs and contribute to the
economy. 
4. Legal - None
5. Property/Assets – Ensuring assets are sustainable and fit for purpose. 
6. Information Technology - None 
7. Equality & Human Rights 
(a) The Recommendations contained within this report have been assessed
in relation to their impact on equalities and human rights. No negative
impacts on equality groups or potential for infringement of individuals’
human rights have been identified arising from the recommendations
contained in the report.  If required following implementation, the actual
impact of the recommendations and the mitigating actions will be
reviewed and monitored, and the results of the assessment will be
published on the Council’s website.

Question 2
Of the options presented for the fabric efficiency rating, which one do you support for the
new SHNZS? 
We agree it’s important to remove fuel costs from the energy efficiency metric and to
concentrate on the fabric of the building as the measure. Social landlords have
control over the fabric.
We also agree with excluding other elements of energy, used within the primary
energy indicator metric. Social landlords do not have control of tenants’ preferences
for white goods or other energy usage and therefore must concentrate on the space
heating demand, where we do have control subject to mixed tenure constraints.
We prefer option 1 based purely on space heating demand of 120-71 by 2033. 
Adding domestic hot water is an added complication that has less gains than space
heating reduction. Although we recognise as space heating demand is reduced, DHW
does increase relatively in importance, we think space heating reduction is more crucial
and should be the primary focus. 
We don’t believe a two staged approach is suitable for our stock profile, where we have
a high percentage of flats with mixed tenure. We would rather minimise consultations in
mixed tenure and attempt to achieve a good standard in a single hit. For stock we own
outright, we may decide to improve beyond 2033 with a space heating demand below
70 but don’t believe this should be mandated within the sector. 
We understand 2033 being the target to align with fuel poverty targets but as a result
we feel the SHNZS must be in place as early as possible in 2025, to give as much time
as possible for landlords to plan, procure and programme works.

Question 3
Are there additional options for the fabric efficiency rating that you think should be
included? If yes, please describe these here: 
Question 4
What, if any, are your views on how performance against the fabric efficiency rating
should be measured? 
We feel the upper range of 120 for space heating demand will likely result in a lot of
current stock not getting any further improvement, limiting progress towards
eradicating fuel poverty, and making the switch to heat pumps more problematic. We
suggest the upper range should only apply to recognised hard to treat property types,
with the majority of stock expected to be under 100 for space heating demand.
We are currently designing retrofits using the PHPP model, as we believe it offers a
more accurate model of reality than RdSAP. We believe if landlords use a model
such as PHPP, the space heat demand from that model should be used as evidence
to pass the SHNZS. But we understand that RdSAP will have to be the baseline. 
We welcome the proposed improvements to SAP, in the hope it models reality better
in the future. However, we believe if only using RdSAP, additional principles of
PAS2035 should be used to help measure performance via pre and post air tightness
test.  Also, the use of sensors to measure condition pre and post retrofit. This is
probably only feasible on an archetype basis though. The condensation and thermal
bridging analysis of SAP should also be considered. 
We will also check some fuel bills pre and post retrofit works. We think these are all
methods that can be used to measure performance, in addition to the use of
RdSAP/EPC’s

Question 5
What are your views, if any, on the proposal for a minimum fabric efficiency standard? 
Question 6
What, if any, are your views on whether homes should not be relet if they cannot meet a
minimum fabric efficiency standard? 
We agree there should be a minimum agreed standard but think this should be set as
a 2033 backstop, to tie in with programmes targeting stock as a whole house retrofit
in one hit. 
The minimum standard should be any measure which can be done with a tenant in-
situ, within the limits of cost effectiveness and technical feasibility We agree with the
listed measures but would remove suspended floor insulation, as this really needs to
be done at void stage (or tenants decanted, and their furniture and floor coverings
put in storage). It is our view that decanting tenants is not feasible in the current
environment of immense housing pressures. 
We think some form of window/door improvement can be made with tenants in-situ
and would add them to the list. (Double glazing, triple glazing, secondary glazing,
energy efficient doors)
We don’t think there should be a simple set rule of removing stock from the letting
pool if it can’t meet the minimum standard. There are too many variables which need
to be considered when assessing whether a property should be relet based on a
minimum fabric efficiency standard. 
Perhaps landlords could consider a rental policy which takes cognisance of the
poorer energy efficiency performance with a reduced rental charge, but it should not
be mandated.

Question 7
What, if any, are your views on whether ventilation and monitoring strategies should be
required where MVHR is not installed? 
Question 8
To what extent do you support the requirement to install a clean heating system by
2045)? 
Strongly support 
Somewhat support 
Neither support nor oppose 
Somewhat oppose 
Strongly oppose 
Don’t Know
Please include any additional comments below. 
We agree a ventilation strategy should be in place for future retrofits. Although
MVHR is desirable, it does add another capital and cyclical cost to retrofit and to
work most efficiently, requires a high standard of air tightness for the home. 
DMEV is a cheaper form of ventilation and has a less onerous maintenance burden
which combined with environmental sensors, can be used to monitor adequate
ventilation performance.
We understand the need for clean heating systems to meet net zero targets and
agree with the backstop date of 2045, as it provides the longest possible time. We
believe this time will be needed for the electrical grid to be brought up to standard
and allow for large infrastructure projects such as district heating, to happen. 
In the meantime, space heating demand reduction will help with carbon emission
reduction from fossil fuel heating still being used.

Question 9
Of the options presented for the interim targets, which one do you support for the
SHNZS? 
Question 10
What are your views on whether neighbouring landlords could work together to reach
such a target on a regional basis? 
We support Option 1 as the best method for our stock to decarbonise by 2045.
We see it as very challenging for neighbouring landlords to work on a regional basis
to achieve such a target, however we are keen to see collaboration and sharing of
knowledge and best practice between landlords. A key difficulty arises from differing
procurement approaches and the timing of coordinating budgets, aligning funding
applications and the complexity of different financial positions, including the lending
restrictions of RSL’s. They all contribute to make a regional approach challenging.

Question 11
Are there any additional options for interim targets that you think should be included? If
yes, please describe these here: 
Question 12
To what extent do you support the requirement for mandatory connections to heat
networks under certain circumstances? 
Strongly support 
Somewhat support 
Neither support nor oppose 
Somewhat oppose 
Strongly oppose 
Don’t Know
Please include any additional comments below. 
We largely agree with the proposed interim targets but feel a 2035 date should be
added of 30% coverage, to encourage change at an earlier point. 
We do understand the difficulties of ensuring the grid is capable and possibly the
requirement for Heat Networks to be in place.
For an urban authority with a high proportion of flats and gas central heating, the
option of large-scale Heat Networks is appealing, and we believe it would be a big
help if mandatory connections were in place. This would give reassurance to
potential investors.

Question 13
To what extent do you support the need for landlords to have an element of discretion to
ensure measures are cost effective and in the best interest of tenants? 
Strongly support

Strongly oppose 
Don’t Know
Please include any additional comments below.
Question 14
What, if any, are your views on whether targets should be varied by guidance from the
Scottish Government in specific circumstances? 
As we do not believe the upper limit to the range is too strenuous to achieve for most
of the social housing stock, the number of cases where discretion would be required
will be relatively small. The overriding requirement to achieve net zero carbon and to
eliminate fuel poverty, should ensure that ultimately meeting the standard is in the
best interest of tenants.
In principle we believe the Scottish Government should have the ability to vary
targets, but these should be subject to consultation and any changes which are then
introduced must allow enough time for landlords to comply with the change. 
With a backstop of 2045, it is acknowledged that there is scope for technical
innovation to occur, which may result in a need for the standard to be reviewed.

Question 16
Do you agree that for some blocks where the local authority or RSL is not a sole or
majority owner, then a phased approach to retrofit work should be undertaken? 
Strongly support

Neither support nor oppose 
Somewhat oppose 
Strongly oppose 
Don’t Know
Please include any additional comments below.
For fairness we believe tenants should be receiving the same quality of housing,
irrespective of where they live. For tenants in mixed tenure there is a strong chance
that they will not receive the same standards but if the SHNZF is applied to mixed
tenure properties and we can inform owners and private landlords that they must
also comply, it may lead to better outcomes.
We don’t believe it’s cost effective or efficient to carry out phased works in mixed
tenure blocks as it can limit what energy efficiency works can be carried out in a way
that doesn’t stop future whole block approaches. We believe a strong approach to
ensuring the SHNZF is applied across multi tenure is required, but with finance
options or funding available to support owners to participate in works.

Question 18
What are your views on the timetable for introducing the new SHNZS? 
Renfrewshire do not have any such sites, so not appropriate to comment.
We would welcome certainty around the new SHNZS and in terms of timing, would
prefer implementation as quickly as possible to allow the maximum time to plan,
procure and carry out works.
