What changed: competence evidence is moving closer to the centre of contractor selection. For a ventilation package, a useful review connects people, supervision, scope, information control and site delivery rather than relying on one card, certificate or company statement.

Why competence is receiving more attention

In July 2026, BESA reported a warning from the Building Safety Regulator that main contractors should strengthen control of subcontractor quality, competence and compliance on higher-risk building projects. The BESA industry update emphasised evidence of management, accountability and quality control across subcontracted work.

Separate GOV.UK guidance for England explains that those appointing designers and contractors must take reasonable steps to appoint organisations and individuals with the necessary competence or organisational capability. The precise legal framework depends on project type and jurisdiction; Scottish projects operate under a different building-standards system. Project teams should confirm applicable duties with their own competent advisers.

What a practical pre-award review can cover

  1. Relevant package experienceAsk for evidence that matches the proposed duct type, building environment, access conditions and role — not simply a general company profile.
  2. People and supervisionIdentify who will manage the package, how site operatives are selected and what supervision is planned for the work.
  3. Defined scope and limitsConfirm that the contractor understands the package boundary, interfaces and any work that remains with others.
  4. Information controlAgree how drawing revisions, technical queries, changes and site instructions will reach the people carrying out the installation.
  5. Quality and evidenceDefine the inspections, photographs, labels, records or handover information expected within the agreed scope.
  6. Capacity and programmeTest whether the proposed labour and supervision reflect the actual workfaces, access and sequence rather than an unsupported total headcount.

Competence is not a single document

A card or training record can support a competence review, but it does not describe how an organisation allocates work, supervises people, manages changes or records delivery. BESA's April 2026 guidance on demonstrating competence describes competence as a continuing management discipline covering skills, knowledge, experience and behaviours.

For procurement teams, that means asking proportionate questions connected to the work being awarded. The evidence required for a straightforward commercial installation package will not necessarily be the same as for a higher-risk or safety-critical scope. The review should be specific enough to reveal whether the proposed organisation and team fit the actual package.

Connect competence to the written scope

A contractor cannot demonstrate control over a package that has not been defined. Before award, record the drawing and specification basis, inclusions, exclusions, interfaces, programme assumptions and expected close-out information. Then use the competence review to test whether the contractor has the people, systems and capacity to deliver that scope.

This also reduces ambiguity after mobilisation. If a design or scope change moves the work beyond the agreed package, the team has a clear basis for reviewing responsibility, competence and programme impact before proceeding.

Questions procurement teams can ask

  • Who will manage and supervise this package, and what relevant experience supports those roles?
  • How will current drawings and changes be controlled on site?
  • How will work be checked against the agreed specification and scope?
  • What information will be recorded during installation and provided at handover?
  • Which parts of the proposed scope require clarification before mobilisation?
  • What programme, access and workface assumptions support the delivery plan?

Cliventa's practical position

Cliventa supports contractor-led ventilation and ductwork installation packages. Suitable opportunities are reviewed against the available drawings, specification, scope, project location, programme and site constraints. Confirmed insurance and workforce information can be supplied during procurement review, subject to the requirements of the enquiry.
