£98.75 million of Welsh Government funding is now live under ORP3 Year 5, covering the period April 2026 to March 2027. For retrofit contractors working in — or seeking to enter — the Welsh social housing market, this represents the most significant funded pipeline currently available in Wales. But access to that pipeline is not open to all. It is conditional on meeting a specific set of compliance requirements: PAS 2030:2023 certification, TrustMark registration, and the ability to operate within PAS 2035-governed projects.
The contractors who move first will be in the strongest position to support Welsh landlords, win PAS 2030 & TrustMark-linked work, and establish themselves in a market that is only becoming more structured.
What Is the Optimised Retrofit Programme — and Why Does It Matter to Contractors?
The Optimised Retrofit Programme (ORP) is the Welsh Government’s flagship initiative to decarbonise social housing stock in Wales. Established in 2020 and backed by over £466 million in cumulative investment, ORP has supported the improvement of more than 31,000 Welsh homes to date. ORP3 Year 5 — covering 2026 to 2027 and known formally as ORP3.5 — continues that trajectory with £98.75 million confirmed by Cabinet Secretary Jayne Bryant in January 2026.
The programme is open to Registered Social Landlords (RSLs) and Local Authorities across Wales. It is not a competitive tender in the traditional sense — eligible landlords submit a proforma application setting out their intended costs and delivery programme. Once approved, they commission their supply chains. That supply chain is where contractors come in.
Critically, ORP is not a blanket scheme. Welsh Government requires a fabric-first, whole-house approach built around a Target Energy Pathway (TEP) for each individual property. Works must be sequenced correctly, evidence must be robust, and every installation must be carried out by a certified, accredited supply chain. That is why PAS 2030, PAS 2035 and TrustMark are not peripheral concerns — they are the structural framework within which all ORP delivery operates.
This programme is also relevant beyond Wales-based businesses. Any contractor seeking to deliver work within Welsh social housing retrofit programmes faces the same compliance expectations, regardless of where their business is registered.
PAS 2030:2023 — The Certification Every ORP Contractor Must Hold
PAS 2030:2023 is the British Standards Institution specification governing the installation of energy efficiency measures (EEMs) in existing homes. It applies to contractors installing insulation, heat pumps, solar PV, ventilation systems, heating controls, and a range of other qualifying measures. Updated in September 2023 and mandatory from 31 March 2025, it replaced the 2019 edition with stronger requirements around whole-house retrofit thinking, moisture management, airtightness strategies, pre-installation inspection, and ventilation design.
The ORP3 Year 5 guidance, published by Welsh Government on 25 February 2026, is explicit:
“Landlords are required to ensure that their supply chain workforce is accredited to PAS 2030 or utilise an umbrella approach for smaller sub-contractors.”
In plain terms: to deliver ORP-funded retrofit work as a named contractor, your business must hold PAS 2030:2023 certification issued by a UKAS-accredited certification body. There are no exceptions to this requirement and no workarounds that give a business its own standing in the market.
What PAS 2030 certification demonstrates
Certification is not a course or a self-declaration. It is a formal third-party assessment confirming that your business operates a quality management system aligned to PAS 2030:2023, that your operatives are competent for the specific measures in your scope, that your installations meet the required specification, and that you are subject to annual surveillance audits to maintain that status. For social landlords and housing associations, it is the auditable assurance they need before appointing a contractor to deliver funded work.
A note on PAS 2030 scope
PAS 2030 certification is not a single blanket qualification. Your certification is specific to the energy efficiency measures your business installs. Insulation contractors, heat pump installers, solar PV contractors, and ventilation specialists each require certification that reflects their measure scope. Getting the scope right at the outset is important — both commercially and for audit purposes. NetRet Group will advise on the right scope for your business before any application is submitted.
What about the umbrella arrangement?
An umbrella arrangement is where a PAS 2030-certified company formally takes responsibility for the installations of a smaller, non-certified sub-contractor. It is permitted under ORP guidance, but the accredited company carries full compliance liability for those installations. If your business is delivering ORP work on a regular basis, relying on another company’s umbrella is a commercially exposed position. Your own certification gives you independence, direct client relationships, and your own standing in procurement processes. For any business with genuine ambition in the Welsh retrofit market, that is the stronger long-term move.
PAS 2035 — The Framework You Work Within
While PAS 2030 governs how measures are installed, PAS 2035:2023 governs the entire retrofit project framework: how properties are assessed, how measures are specified, how risks are managed, and how the work is coordinated and evidenced. Every ORP project must operate within a PAS 2035-compliant structure.
PAS 2035 defines specific roles within a retrofit project:
- Retrofit Assessor: carries out the initial assessment of the property, establishing its baseline condition, energy performance, and suitability for various measures.
- Retrofit Coordinator: manages the overall project, specifies the measures to be installed, oversees compliance with the medium-term improvement plan (MTIP), and takes responsibility for evidencing outcomes.
- Retrofit Designer: produces technical designs for complex or bespoke measures, particularly where ventilation, moisture risk, or structural considerations are involved.
- Installer: that is you, as a PAS 2030-certified contractor, carrying out installations to the Retrofit Coordinator’s specification.
As a contractor, you will not typically hold the Coordinator or Assessor role — those are separate specialist functions, usually carried out by independent practitioners or the landlord’s appointed team. But you must understand how those roles interact with your work. You will be required to follow the Coordinator’s installation specification, maintain records in a format that supports TrustMark lodgement, and provide evidence that your installations meet the required standard.
Understanding PAS 2035 — even at a working knowledge level — makes you a more credible supply chain partner. It reduces friction on site, speeds up evidence collection, and demonstrates to commissioning landlords that your business operates at a professional level consistent with the programme’s expectations.
TrustMark — Why Registration Is Inseparable from ORP Delivery
TrustMark is the UK Government-endorsed quality scheme for work carried out in and around the home. For ORP, it is not optional. The Welsh Government guidance requires that all ORP retrofit works are lodged on the TrustMark Data Warehouse. Every installation — from insulation to heat pumps — must be recorded and evidenced through TrustMark’s lodgement system.
To lodge on the TrustMark Data Warehouse, a contractor must hold TrustMark registration. TrustMark registration for relevant energy efficiency measures requires PAS 2030:2023 certification. The chain is direct: no PAS 2030 means no TrustMark registration, and no TrustMark registration means no ability to lodge ORP works.
NetRet Group is a TrustMark Scheme Provider — the first in Wales. That means we can manage both your PAS 2030 certification and your TrustMark registration through a single relationship, removing duplication, simplifying your administrative pathway, and ensuring your compliance infrastructure is aligned from the outset.
Key Dates: ORP3 Year 5
Social landlords are working to these deadlines now. Contractors not ready when procurement decisions are made will not be included in delivery programmes.

ORP3 Year 5 application submission deadline. Social landlords must submit proforma applications to Welsh Government. Named supply chain contractors should hold PAS 2030 certification to strengthen bid submissions.
30 April 2026
Grant decisions issued. Confirmed applicants begin commissioning their supply chains. Certified contractors go directly onto delivery programmes.
1 September 2026
WHQS TEP milestone. Social landlords must demonstrate 75% of full Target Energy Pathways completed for their whole stock. Delivery activity peaks around this period.
November 2026
Mandatory ORP Mid-Term Progress Meeting. Welsh Government reviews programme delivery with all funded landlords. Supply chain performance and compliance is assessed.
31 March 2027 — Hard deadline
All ORP-funded works must be completed and lodged on the TrustMark Data Warehouse. No works outstanding after this date are eligible for grant funding.
Training: Building the Internal Capability That Supports Certification
PAS 2030 certification is a business-level qualification, but the competency behind it sits with your people. Certification bodies assess the skills and training of your operatives as part of the audit process. Gaps in training records, inconsistent installation practices, or operatives who cannot evidence their competency in a specific measure are the most common causes of audit delay and non-conformance.
NetRet Group supports contractors with training aligned to PAS 2030 and PAS 2035 requirements. This includes retrofit awareness programmes, measure-specific competency development, assessor pathways for those who want to build towards PAS 2035 roles, and preparation for the documentation and quality management expectations of a PAS 2030 audit.
Training is not a box-ticking exercise. It is the practical foundation that makes certification achievable faster, reduces your audit risk, strengthens your tender submissions, and builds the internal confidence that distinguishes a genuinely compliant business from one that is hoping to pass a checklist.
Why Welsh Contractors Choose NetRet Group
Wales’ Only UKAS-Accredited PAS 2030:2023 Certification Body NetRet Group Ltd is the first and only UKAS-accredited PAS 2030:2023 certification body based in Wales (UKAS No. 28611).

Our certificates are not self-declarations. They are independently verified credentials that withstand scrutiny.
Frequently Asked Questions
I hold PAS 2030:2019. Am I still eligible for ORP work?
No. PAS 2030:2019 was withdrawn on 31 March 2025. If you have not transitioned to the 2023 standard, your certification is no longer current and you cannot be named as a compliant contractor in an ORP supply chain. Contact NetRet immediately to arrange a transition assessment — the process is faster than a first-time application, but it cannot be left until the last moment.
My business is based in England. Does ORP compliance still apply to me?
Yes. Any contractor seeking to deliver retrofit work within Welsh social housing programmes — regardless of where the business is based — is subject to the same compliance requirements as a Wales-based business. ORP compliance is determined by the location of the works and the requirements of the Welsh Government funding conditions, not the contractor’s registration address.
Can I use an umbrella arrangement to access ORP work without my own certification?
You can, in the short term, but it is a commercially exposed position. An umbrella arrangement means an accredited company takes legal responsibility for your installations — which limits your independence, restricts the contracts you can bid for in your own name, and leaves you dependent on a third party’s continuing accreditation. For any business with consistent ambition in this market, your own PAS 2030 certification is the stronger and safer route.
What measures can my business be certified for?
PAS 2030 covers a wide range of energy efficiency measures: external and internal wall insulation, cavity wall insulation, loft and floor insulation, heat pumps (air source and ground source), solar photovoltaic systems, heating controls, ventilation systems, and more. Your certification scope is specific to the measures your business actually installs and can evidence. NetRet will help you identify the right scope before application so that you are not paying for certification in measures outside your capability or commercial interest.
How long does PAS 2030 certification take?
Typically between three and six months from initial application to certificate issue, depending on how prepared your quality management system and training records are at the outset. The process can be accelerated by thorough preparation. NetRet will identify any gaps before the formal audit so that the assessment proceeds smoothly. Starting now is essential for contractors who want to be ready for ORP Year 5 delivery.
Does PAS 2030 certification automatically give me TrustMark registration?
Not automatically — but as a TrustMark Scheme Provider, NetRet Group manages both through a single relationship. This removes duplication in your compliance process and ensures your PAS 2030 certification and TrustMark registration are aligned, which is critical for ORP lodgement requirements.
What is the strongest position for a contractor to be in right now?
Certified, scoped correctly, with a quality management system in place and operatives whose training records are current and complete. Beyond that: an understanding of how PAS 2035-governed projects work, so you can operate confidently within the commissioning structures that social landlords use. Contractors who present themselves as ready — not just interested — win procurement conversations. NetRet Group helps you get there.
Conclusion: ORP Is an Opportunity, But Only for Contractors Who Are Ready
The Welsh ORP Year 5 funding round is live, the direction of travel is clear, and the compliance framework is mature. Social housing retrofit in Wales is no longer an emerging market — it is a structured, evidence-driven programme with defined quality standards that are enforced through funding conditions, audit, and lodgement requirements.
Contractors who want a place in that market should not treat PAS 2030:2023 as optional or something to revisit later. It is the route in. Combined with TrustMark registration and a working understanding of PAS 2035 project structures, it positions your business as a credible, audit-ready supply chain partner — the kind of contractor that Welsh social landlords are actively seeking to appoint.
The businesses that move now will be the ones securing delivery programmes from April 2026 onwards. The businesses that wait will be watching from the outside as that work is allocated to certified competitors.
ORP is an opportunity. But it is only an opportunity for contractors who are prepared to meet the standard it demands.
