Following a satisfactory assessment, technical inspections, verification of the assessment report, and completion of any corrective actions, we shall issue a certificate, which is valid for one year.

Subsequent yearly certificates are issued subject to continued satisfactory performance being achieved through surveillance assessments, which shall be carried out on 1-10% of your installations.

If a major non-conformance is found during the initial assessment process a recommendation for certification shall not be made until either corrective action has been verified by a site visit (which may be chargeable) or appropriate documentary evidence of corrective action has been submitted and approved by us.

If a major non-conformance is found during surveillance assessment you shall be required to carry out corrective action within an agreed timescale, which shall normally be no greater than 21 days following the assessment.

Where there are a high number of non-conformances (i.e. more than 5), there will be additional charges to review these due to the time it takes for additional assessment.


Conformance Levels



Non-conformance is the absence or failure to implement and maintain one or more requirements of the reference standard under assessment.

There are two grades of non-conformance:

Major Non-Conformance

The absence or failure to implement and maintain one or more requirements of the management system reference standard, or a situation which would, based on objective evidence, raise significant doubt as to the capability of the system to achieve the policy and objectives of the system.

A major non-conformance would also be raised if the organisation breached a legal requirement.

Certification shall not be granted or continued to be certified until all major non-conformities have been corrected and the corrective actions verified.

Minor Non-Conformance

A vague or unrevealing element of the management system, which may result in a small discrepancy that could be corrected with minimal organisational, operational, or technical change and within a reasonable time frame, (as opposed to a major non-conformance where the facility has not addressed or adequately addressed the criterion).

TrustMark Surveillance Visits Agreement

It is part of the Licence Plus requirement that Surveillance Visits commence as soon as your initial certification is granted. These are calculated as a % of your total number of installs; which will be between 1-10% dependant on your score.

These have to be completed before your next yearly head office assessment.

As part of your certification agreement, you must:

  • Submit your weekly installation numbers so that the number of required visits can be monitored and calculated against the percentage required.
  • As soon as the total number of % of surveillance visits need hits three, a list of properties will need to be submitted so that technical inspections can be arranged.
  • Agree to a monthly surveillance assessment program to keep on top of the number of technical assessments required.
  • It is a contractual requirement with Green Deal Orb that you submit your weekly installation figures to your Certification Body. Failure to do this could lead to both PAS 2030 Certification and TrustMark to be suspended. 

Special Assessment Visit

We reserve the right to make an additional chargeable Special Assessment Visit in the following circumstances:

  • Where assessment is required verify the closure of Major non- conformances
  • At initial evaluation the condition of the management system or scope of certification is not as described during the application stage
  • Significant modifications to the management system have taken place
  • Significant changes to the organisation, scope or processes have occurred which were not notified to us in sufficient time prior to the standard assessment visit
  • Where we are required to investigate information on serious accidents or a breach of legislation resulting in the involvement of the regulatory authority
  • A TrustMark notification to us that highlights concern as an Installer of Interest Assessment Plan

TrustMark Applicants

Any applicants wishing to gain TrustMark registration are advised to read their downloadable guidance found via this link to ensure the scheme requirements are fully understood. Please note all applications will be audited against its standards to confirm compliance before registration is granted:

Helpful Information, Guidance & Advice For Work Done Around Your Home (trustmark.org.uk)

Any installer who does not declare their outstanding Technical Monitoring fails during the application process, runs the risk of being automatically removed from the TrustMark scheme.

Installer of Interest Assessment Plan

Where there is an occasion that TrustMark have highlighted a high percentage of fails via their Technical Monitoring we reserve the right to move the organisation onto our “Installer of Interest Assessment Plan”.

We have designed this programme to provide Installers who have been identified as problematic with a chance to improve so that they can retain certification if they demonstrate improvement, rather than move to an immediate removal of their TrustMark registration.

  • This is a short-term assessment programme in which the Installation Organisation will have the opportunity to demonstrate their move to reduce TM fails so that they can continue to retain their certification and TrustMark registration.
  • The programme has been designed to ensure that the Installation Organisation is moving towards sustainable improvement and reduce risk of TM fails.
  • The installer organisation will be required to:
    • Evidence corrective actions via a Special Assessment Visit to address the root cause of the TM fails.
    • Submit corrective actions through an improvement plan to demonstrate how the business intends to improve moving forward as agreed during the Special Assessment Visit
    • Evidence to show an improvement in technical fails.
  • There is an additional fee to be moved onto the “Installer of Interest Assessment Plan” to cover the additional assessment and administration time required to closely monitor the installer organisation.
    • £995 + VAT (inclusive of expenses) for a Special Assessment Visit
    • £595 +VAT administration management fee per month
    • Once the improvement plan is in place a technical inspection will be required against each measure. We will offer for Special Assessment Inspections to coincide with your surveillance assessments.
    • If this can’t be coordinated to coincide with surveillance visits each Special Assessment Technical Inspection will be £500 +VAT
  • PAS 2030 Certification and TrustMark Registration will be removed where an organisation is
    • Not willing to move onto the Installer of Interest Assessment Plan when required.
    • Fails to comply with the agreed corrective actions from the Special Assessment Visit
    • Becomes uncooperative and unresponsive.

Once we are satisfied that the Installation Organisation has demonstrated a change in their procedures to address the root cause to reduce risk, they will be moved back onto our standard surveillance programme.

Customer Complaints about your Organisation

If we receive a complaint about your organisation, we have a process in place that will need to be followed:

  1. The complaint will be logged on our system and we will acknowledge receipt of the complaint within 72 hours to the complainant.
  2. We will ask you as the installation company to provide details around the complaint so we can carry out an investigation.
  3. We will ask that you – as the installation organisation – to contact the complainant direct in the first instance to try and resolve the issue.
  4. Within four weeks we would expect in most cases for the complaint to be resolved with the installation company and complainant direct and we will ask you to provide evidence of this.
  5. If within the four weeks, the issue is still outstanding the complainant may be given an option to access ADR (Alternative Dispute Resolution)
  6. If you are a TrustMark registered business, and the complainant feels the issue still has not been resolved, then we will provide them with an option to escalate the dispute to the Dispute Resolution Ombudsman (DRO) when all steps above have been exhausted.

As part of your certification agreement, we reserve the right to:

  1. Carry out a special visit to the complainant’s property and/or your head office to investigate the complaint. This will be at cost to the installation organisation. Failure to comply with this could result in suspension of certification and TrustMark registration.
  2. Ask for the installation organisation to provide evidence of how they have dealt with the complaint to demonstrate that process has been followed. Failure to comply with this could result in suspension of certification and TrustMark registration.
  3. Increase risk scoring of the business (resulting in an increase of % for Surveillance Inspections) where we find that the installation organisation has failed to meet their own process.
