Note: this replaces the original PAS 2030 scheme update technical bulletin dated 21 May 2025 and the 30 June 2025 update
1. Introduction
Following the report of concerns relating to a significant number of non-compliant installations carried out by certified installers of PAS 2030 energy efficiency measures, UKAS has been working with Ofgem, DESNZ, TrustMark and the accredited certification bodies (CBs) to determine what improvements might be needed to the certification schemes. UKAS has also undertaken a programme of additional assessments to CBs to ensure they are taking the necessary remediation activities.
This bulletin outlines clarifications and additional actions that CBs are required to undertake in response to feedback on learning points identified to date. These need to be taken into account as part of the assessments of installers by CBs accredited by UKAS for all PAS 2030 energy efficiency measures (EEM).
In January 2025, a requirement for CBs to audit 20% of identified external wall insulation (EWI) installations carried out by their certified installers was set by the Minister, with Ofgem tasked with overseeing the additional audits; this was set out in a letter to from the Minister to CBs in January. Further requirements and instructions to CBs have been issued by Ofgem in their letter to the accredited installers dated 11 March 2025; accredited CBs are required to follow the requirements specified in that letter and these requirements will be assessed as part of the ongoing programme of additional assessments.
This bulletin must be read in conjunction with PAS 2031:2019 Certification of energy efficiency measure installation in existing buildings and insulation in residential park homes. Further improvements to PAS 2031 have been identified to harmonise the activities of the CBs that will be taken into account at the next revision of the specification. In the meantime, CBs accredited for certifying PAS 2030 installers are required, in addition to the requirements for accreditation set out in ISO/IEC 17065 and PAS 2031, to take account of the specific requirements set out below. CBs also need to ensure that all other relevant obligations and requirements that apply to these activities are met e.g. compliance with Building Regulations.
2. Specific requirements (applicable to all EEM unless indicated)
2.1 Initial evaluation
2.1.1 When a certification body (CB) certifies an installer for the first time, the risk evaluation status of an installer shall be ‘high’ as detailed in Table 2 of PAS 2031:2019. Where an installer is transferring its certification to another CB, that CB shall take account of the information available concerning the existing certification held in evaluating risk. Any justification for a lower risk rating shall be fully documented.
2.1.2 It has been agreed via the Ofgem Roundtable meeting that CBs will not enable an installer to hold certification for the same EEM with more than one CB. Therefore, CBs are required to have in place measures to ensure they do not certify installers that already hold certification by another CB for the same EEM. An agreed process to ensure suitable cooperation and that actions are taken is being established. CBs are required to ensure that they implement this agreed process to prevent dual certification of installers.
2.1.3 Where CBs are accepting new applications from existing registered installers or transfers from an installer to move its certification from one CB to another, (either through an organised “CB to CB transfer” or where, of their own volition, an installer leaves one CB and applies to another); The CB shall have in place procedures for the exchange of relevant information with the previous CB to ensure a full risk evaluation can be undertaken. Information requested shall include, but not be limited to:
- Details of applications submitted to other CBs
- Details of certification(s) held with other CBs
- Details of previous surveillance audits
- Details of outstanding and/or scheduled audits by other CBs
- Information relating to the risk evaluation in accordance with PAS 2031
- Details of any open findings or outstanding remediation from previous audits
- Details of any sanctions applied by other CBs
- Details of any outstanding complaints
2.1.4 All CBs shall establish procedures to ensure information can be provided to a new CB to support the transfer process, where it is requested.
2.1.5 As part of either the transfer or new application, if not already agreed as part of a “CB to CB transfer”, the new CB shall ensure they have a signed declaration from the applying business as part of their application; to disclose and confirm they will rectify any outstanding Trustmark non-compliance or requested remediation works from any prior certification held with a previous CB. Failure to remediate or resolve non compliances as required may result in applicable sanctions from the new certifying CB.
2.1.6 In line with the above, should a non-compliance or complaint be discovered after the transfer of new registration under the previous CB, the new CB may be required to use the sanctions available to them to support the installer’s non-compliance or complaint resolution, which may include remediation. It is the responsibility of the new certifying CB to ensure their procedures have suitable methods of ensuring the installer operates in line with ongoing installer competency requirements as set out by the scheme.
2.1.7 Reasonable lines of cooperation shall exist between the old and new CB to ensure remediation can take place. In the event that a reasonable outcome cannot be secured for the homeowner, the case shall be escalated to Trustmark.
2.2 Surveillance evaluation
2.2.1 PAS 2031:2019 requires the CB to review the installer’s processes at least annually. The surveillance cycle is to begin with the date of initial certification and the CBs are required to have in place procedures to ensure that the surveillance activities are completed within the twelve-month period. Any exceptional circumstances that prevent the completion of the activities within a twelve-month period shall be justified and under no circumstances shall they be permitted to extend beyond a period greater than sixteen months. As previously noted, CBs are required to complete their surveillance of the 20% of identified EWI installations in accordance with the requirement set by DESNZ/Ofgem. Once this target is completed, CBs are able to revert to the risk-based PAS2031 auditing process until further notice.
2.2.2 CBs shall have processes to ensure pre-installation and mid-installation assessments are carried out onsite at a live site during the correct stage of the installation.
- In the exceptional circumstance that a surveillance year is completed late, the completion of a surveillance cycle does not change the start date, and the next surveillance cycle remains anchored to the anniversary of the initial certification.
- During the surveillance inspections the CB shall continue to complete the risk assessment according to PAS 2031. The type and extent of findings raised during inspections shall be classified and used to update an installer’s risk rating in line with PAS 2031:2019 and any additional requirements specified by Ofgem.
2.3 Action in the event of nonconformity
2.3.1 PAS 2031:2019 specifies that installer nonconformities shall be addressed within eight weeks of identification. In exceptional circumstances where nonconformities are not addressed within this timeframe, the CB shall ensure that further action shall be taken within twelve weeks of identification which may include suspension or withdrawal of the installer’s certification.
2.4 Reinstatement of certification
2.4.1 Certification can be reinstated following suspension. A CB shall determine the risk level associated with the reinstated certification, irrespective of any additional surveillance requirements. The justification for the risk level shall be documented.
3. UKAS Assessments
3.1 Until further notice UKAS will carry out an assessment of bodies delivering the PAS 2030 scheme every three months.
- Prior to the quarterly assessment a CB shall submit information detailing the inspection activities carried out during the preceding three months and provide a list of inspections planned for the following three months.
- UKAS witnessed assessments (WA) for EEMs will be identified from lists of surveillance evaluations to be carried out by certification bodies. This will be carried out on a quarterly basis and the EEMs to be witnessed will be identified at the time that the opportunities are identified. The numbers of witnessed assessments will be in accordance with UKAS publication CIS 8.
The changes noted in this communication are effective immediately. Compliance with requirements stated in this Technical Bulletin will be reviewed during UKAS assessments.
