Policy is pointless if the developments are located in the wrong areas as the need to travel will far outweigh any net zero houses.

Crynodeb o'r Gynrychiolaeth:

I support this policy but do question why such a long period for the initial space heating demand requirements and energy use requirements. The council should be pushing for the higher efficiency standards immediately rather than up until 2030. It feels like the council is deliberately giving housing developers an opportunity to increase profits and build cheaper less efficient housing by having these dates knowing the vast majority of new housing within the plan is likely to be delivered before 2030.

Crynodeb o'r Gynrychiolaeth:

Net zero building techniques would be a wonderful thing, but have Planning had anything but "vague promises" from Building firms? Are there statutory teeth to deal with defaulting behavior? From everything I have read recently about about such firms in the UK, compared to Europe, there can be a deep reluctance to engage in net zero building techniques. It is seen to eat into their profits. I am sure promises might be made but (as in the recent Barry waterfront developments) unfulfilled promises (and contracts) from such firms often limp along into long expensive legal cases.

Crynodeb o'r Gynrychiolaeth:

I fully support the ambition of VoGC to address, mitigate and adapt to anthropogenic climate change by applying demand-based metrics to reduce carbon emissions from the built environment. Monmouthshire County Council are advancing similar proposals to Inspection this summer and multiple LAs in England have successfully introduced similar targets, defining space heating demand (SHD) and energy use intensity (EUI) targets as scientifically robust metrics that align with best practice for achieving Net Zero emissions. It has been exhaustively demonstrated that better performing buildings, those with improved (reduced) SHD and EUI, more economically achieve operational Net Zero than those delivered to business as usual (BAU) and deliver considerable lifecycle cost savings for occupants. The Building Regulations methodology through the standard assessment procedure (SAP) is deeply flawed and inconsistent with efficiently or effectively achieving Net Zero (as the 2021 report for the Department for Business, Energy and Industrial Strategy "Making SAP and RdSAP 11 fit for Net Zero" concluded) and the replacement Home Energy Model (HEM) has not been demonstrated to be any better aligned. In the context of the declared Climate Emergency, action by the Senedd and Westminster is not moving fast enough to deliver our legal commitments to decarbonise.

Delete the policy and instead allow Building Regulations to set the way homes are constructed and their energy efficiency through Part L & F.

If the policy is not fully removed, amend it to remove the energy use intensity element.

New higher Building Regulation standards will be published before this plan's adoption, so they will apply to many of the homes delivered by the plan.

Policy CC1 – Residential Operational Net Zero Carbon Development

Persimmon Homes has significant concerns regarding Policy CC1 and objects to it on the basis that it
replicates requirements already being progressed at a national level through Welsh Government’s Future Homes Standard (FHS). The FHS is intended to deliver “zero carbon ready” homes via a unified Building Regulations framework, making additional local policy unnecessary. At present, Building Regulations Part L1A sets out the standards for energy efficiency in new dwellings, and Persimmon already designs its homes to go beyond these minimum thresholds. This includes enhanced insulation
and improved building fabric performance, with reduced U values for elements such as walls, roofs, floors and windows to minimise heat loss. As a result, our homes typically achieve strong Energy Performance Certificate (EPC) ratings, generally in the A–B categories.

Introducing further operational net zero requirements at a local planning level risks adding cost, complexity and uncertainty, potentially affecting the viability and deliverability of housing sites. The Development Plans Manual for Wales is clear that local plans should not repeat national policy or seek to regulate matters already addressed through other statutory regimes. On that basis, Policy CC1 is not considered to be justified and is inconsistent with the second test of soundness.

The proposed shift in standards from April 2030 represents a substantial and abrupt escalation in
expectations. Although the policy refers to schemes such as Tai ar y Cyd and AECB CarbonLite, these examples largely relate to grant funded affordable housing projects. There is no robust evidence that equivalent standards can be met on mainstream housing sites without undermining overall viability. The Development Plans Manual requires policies to be based on strong evidence and to be realistically deliverable across the plan period. Without this, there is a risk that the proposed policy could impede
housing delivery and compromise the RLDP’s ability to meet identified needs.

Policy CC1 could also lead to inconsistent energy performance requirements across Local Planning
Authorities in Wales, contradicting the advantages of a unified regulatory system via Building Regulations. For volume housebuilders working across several authority areas, this would introduce unnecessary variation and complication. The DPM highlights the importance of policies that support
housing delivery and avoid avoidable burdens. By introducing bespoke modelling thresholds and
operational monitoring requirements, CC1 risks blurring the line between planning and Building Control,
raising questions about the policy’s justification and practical application.

It is Persimmon’s view that Policy CC1 is premature and that it is more appropriate for such matters to be addressed through building control rather than planning policy. In its current form, the policy risks impacting housing supply, affordable housing delivery and overall implementation across the plan period. For these reasons, we consider that Policy CC1 fails to satisfy the relevant tests of soundness and should be removed from the emerging RLDP.

Crynodeb o'r Gynrychiolaeth:

Not only is the approach proposed to be taken in Policy CC1 out of line with the approach that is to be taken in England and the approach that has been taken in Wales, it is considered that there is insufficient certainty around the ability for these works to be delivered when they are required to be without harming viability.

Crynodeb o'r Gynrychiolaeth:

Persimmon Homes, strongly object to Policy CC1 on the basis that it duplicates Welsh Government’s Future Homes Standard (FHS), which is intended to ensure all new homes are “zero-carbon ready” through a consistent national Building Regulations framework.

Building Regulations Part L currently sets the requirements for energy efficiency in new homes, with the current dwellings built by Persimmon Homes being designed to exceed the minimum requirements of Part L by incorporating enhanced insultation and improved building fabric performance. This includes low U-values for key elements such as walls, roofs, floors and windows to minimise heat loss and improve overall energy efficiency.
As a result, Persimmon Homes are achieving a high rating under the Energy Performance Certificate (EPC) System, typically within the A-B range.

Introducing a separate and potentially more onerous operational net zero requirement at the local level risks imposing additional cost and complexity that undermines site viability and deliverability. The Development Plans Manual for Wales is clear that development plans must avoid repeating national policy and should not introduce requirements that are more appropriately addressed through other regulatory regimes. In this respect, Policy CC1 is not considered justified or appropriate and thereby conflicts with the second test of soundness set out within the DPM.

The proposed step change in standards from 1 April 2030 (particularly the reduction in space heating demand from 40 kWh/m²/year to 15 kWh/m²/year) represents a significant and abrupt step change in performance expectations. Whilst reference is made to initiatives such as Tai ar y Cyd and AECB CarbonLite, these have largely been associated with grant-funded affordable housing schemes. There is no clear evidence that equivalent standards are able to be delivered on mainstream housing sites without compromising their overall viability. On that note the Development Plans Manual requires policies to be underpinned by robust evidence and deliverable over the plan period. In the absence of which the proposed policy could well prevent housing delivery and undermines the emerging RLDP’s ability to effectively meet housing need.

Further to the above Policy CC1 also risks creating fragmented energy performance standards across different Local Planning Authorities in Wales. This contradicts the benefit of a consistent national approach through Building Regulations and makes it significantly more difficult for mainstream housebuilders operating across multiple authority areas to deliver homes efficiently.

The DPM emphasises the need for development plans to create policy frameworks that encourage housing delivery and avoid unnecessary complications. By introducing bespoke operational monitoring requirements and energy modelling thresholds the policy as currently worded blurs the boundary between planning and Building Control functions. In turn this raises concerns as to whether the policy is justified and capable of being applied consistently across the board.

Finally, the Council’s own Viability Assessment (Paragraph 6.60 of BP42) acknowledges current uncertainty given the outcome of Welsh Government’s consultation on this topic are still unknown at the time of writing. In the event the Welsh Government decide to peruse national regulation progresses, it may be more appropriate for such matters to be addressed through Building Control rather than planning policy. Once again, this reinforces Persimmon’s concern that Policy CC1 is premature and not in general conformity with national policy. As drafted, the policy risks undermining the council’s proposed housing supply, affordable housing delivery rate and general implementation over the plan period. For these reasons, we believe it fails to meet the relevant tests of soundness and should be omitted from the proposed RLDP.

Ymatebydd: Taylor Wimpey

Crynodeb o'r Gynrychiolaeth:

Taylor Wimpey formally expresses significant concerns regarding Policy CC1 (Residential Operational Net Zero Carbon Development), which mandates that new build developments achieve net-zero operational emissions. This policy requires adherence to a specific energy hierarchy, setting stringent space heating and energy use intensity standards from the adoption of the RLDP through 2030 and beyond. It further requires on-site renewable electricity generation equivalent to a development's annual energy consumption, only allowing for off-site contributions or heat network connections when on-site solutions are technically unfeasible.

A primary objection raised by Taylor Wimpey is that setting local requirements that exceed national Building Regulations, such as the 2025 Future Homes Standard, is inappropriate and creates an uneven framework for housebuilders. They argue that Building Regulations are the proper mechanism for establishing fixed technical requirements. In the English context, a Written Ministerial Statement—which has been upheld by judicial review—clarified that local plans should not set energy efficiency standards stricter than national regulations. While Taylor Wimpey acknowledges this is a Westminster position, they contend it is incorrect to suggest there is a clear emerging trend for such localized policies in England.

Furthermore, Taylor Wimpey notes a lack of precedent within the Welsh planning landscape. They point out that two recently adopted RLDPs in South East Wales did not include such policies, leading to a lack of confidence that Policy CC1 will be found sound at examination. The company also questions the robustness of the Council’s viability evidence, noting that the cost analysis is based on only three building typologies. This narrow scope fails to account for the broad range of house types used by active developers across Wales, which Taylor Wimpey suggests leads to a significant underestimation of delivery costs.

The financial viability of these requirements is a major point of contention, as Taylor Wimpey’s experience suggests the actual cost per unit is closer to £15,000 or £20,000, far higher than the Council’s estimates. They also highlight a significant timing gap in the evidence; the cost assessments were established in early 2024, yet the housing trajectory does not forecast first completions until 2028 or 2029. This five-year lag between the cost baseline and actual delivery creates unacceptable uncertainty. Consequently, Taylor Wimpey concludes that Policy CC1 is out of step with broader planning approaches and lacks the necessary certainty to be implemented without harming the overall deliverability of housing.

Barratt Redrow strongly object to Policy CC1 on the basis that it duplicates Welsh Government’s Future Homes Standard (FHS), which is intended to ensure all new homes are “zero-carbon ready” through a consistent national Building Regulations framework. risks imposing additional cost and complexity that undermines site viability and deliverability.

The Development Plans Manual for Wales is clear that development plans must avoid repeating national policy and should not introduce requirements that are more appropriately addressed through other regulatory regimes. In this respect, Policy CC1 conflicts with the principle that plans should be clear, proportionate and not duplicate national controls, raising concerns under the tests of soundness relating to coherence and consistency with national policy (Test 2) and whether the plan is justified (Test 3).

The proposed step change in standards from 1 April 2030 — particularly the reduction in space
heating demand from 40 kWh/m²/year to 15 kWh/m²/year — represents a significant and abrupt
escalation in performance expectations. Whilst reference is made to initiatives such as Tai ar
y Cyd and AECB CarbonLite, these have largely been associated with grant-funded affordable
housing schemes. There is no clear evidence that equivalent standards can be viably delivered
across mainstream private housing schemes without public subsidy.

Policy CC1 also risks creating fragmented energy performance standards across different Local Planning Authorities in Wales. This undermines the benefit of a consistent national approach through Building Regulations and makes it more difficult for volume housebuilders operating across multiple authority areas to deliver homes efficiently at scale.

Furthermore, the demands of Policy CC1 have to be considered in the context of all of the other demands that impact on development viability (e.g. affordable housing). The Council must provide evidence that an assessment has been undertaken to demonstrate that development, specifically the housing allocations in Policy HG1, can bear the cumulative policy costs of the RLDP, including Policy CC1.

Crynodeb o'r Gynrychiolaeth:

The policy should clarify that it applies only to regulated energy use.
If this policy is to be kept in the RLDP, there must be some flexibility introduced for the requirements of Policy CC1 to fall away should Building Regulations catch up or exceed or require different provisions than the requirements of the policy during the lifetime of the RLDP.
Clarification is also required on how the contribution to the Council’s Project Zero fund is to be calculated and whether the timeframes in the policy relate to the date of planning approval.
The policy wording should be amended so that the performance requirements apply based on the date of planning permission rather than the RLDP adoption date. Without this amendment, approved schemes could unnecessarily require variations via Section 73 or Non-Material Amendment applications.

Members welcomed the inclusion of specific climate change mitigation and adaptation measures under section CC1-CC6, noting the considerable attention given to Net Zero transition proposal relating to public buildings and energy. Whilst the evidence presented does not include the UK Climate Change Committee Report, Members were pleased to see that CC1-CC6 largely reflect the Committee’s finds and are tailored to a transition which reflects what is presently feasible. This is providing that the necessary skills to understand and undertake carbon assessments within a policy implementation and regulation context are readily available.
