If you manage a framework or Dynamic Purchasing System that includes electrical works, you evaluate contractor submissions regularly. The challenge is not finding contractors who meet the minimum requirements — it is distinguishing between contractors who will deliver consistently and those who will create problems that consume your time for the duration of the framework period.
This guide covers the evaluation criteria that matter most, what good looks like for each one, and the red flags that indicate a contractor submission is weaker than it appears.
Why Framework Appointment Matters for Electrical Works
Framework appointment is not just a procurement mechanism — it is a risk management decision. The contractors you appoint to your framework will deliver works across your estate for 2-4 years. A poor appointment creates:
- Compliance risk — inconsistent documentation, missed testing schedules, unresolved remedial works
- Operational risk — disruption to occupied buildings, tenant complaints, programme delays
- Commercial risk — scope disputes, variation claims, invoicing errors
- Reputational risk — your framework users lose confidence in the panel and procure outside it
Getting the evaluation right at appointment stage prevents these problems from materialising during delivery.
Technical Competence
Technical competence is the foundation. Minimum requirements are straightforward — NAPIT registration, BS 7671 compliance, appropriate ECS/CSCS cards. But minimum requirements only confirm eligibility. To assess actual competence, evaluate:
Scope relevance: Does the contractor regularly deliver the type and scale of work your framework covers? A contractor with extensive domestic experience but limited commercial portfolio work is not a good fit for a multi-site commercial framework, regardless of their accreditations.
Case study evidence: Request case studies that demonstrate delivery of comparable scope. Look for specific KPI data — completion rates, defect rates, response times — not narrative descriptions of what the contractor did. A case study without measurable outcomes is a marketing document, not evidence.
Methodology: Ask for a methodology statement for a representative project within the framework scope. The response should describe specific processes — pre-start surveys, isolation procedures, live environment protocols, handover processes — not generic statements about quality and safety.
Governance and Quality Management
Governance separates contractors who deliver consistently from those who deliver well occasionally. For an example of what strong governance looks like in practice, see our governance and compliance framework. Key indicators:
- ISO 9001 certification — demonstrates a structured quality management system, not ad-hoc quality control
- ISO 14001 certification — environmental management, increasingly required for public sector frameworks
- ISO 45001 certification — occupational health and safety management (note: some contractors are in the process of achieving this; ask for evidence of progress and expected certification date)
- CHAS, SafeContractor, or Constructionline accreditation — health and safety pre-qualification
- Documented QA processes — inspection and test plans, non-conformance reporting, corrective action procedures
The key question is not whether the contractor holds these certifications, but whether they can demonstrate how the management systems work in practice. Ask for an example of a non-conformance report and how it was resolved. A contractor with a genuine quality management system will have examples readily available.
Financial Standing
Financial assessment protects your framework from contractor insolvency mid-contract. Evaluate:
- Accounts filed at Companies House — look for consistent turnover, positive net assets, and adequate working capital
- Credit rating from a recognised provider (Dun & Bradstreet, Creditsafe)
- Insurance cover levels — Employers Liability (minimum £10m for most frameworks), Public Liability (£5m minimum, £10m preferred), Professional Indemnity (£2m minimum), Contractors All Risks
- Payment practices — check the contractor payment reporting on gov.uk for average payment times and percentage of invoices paid within terms
A contractor with strong technical capability but weak financial standing is a risk. Equally, a large contractor with strong finances but no track record in your specific sector may not deliver the service quality your framework users expect.
Social Value
Social value is typically weighted at 10-20% in public sector framework evaluations. The difference between a strong and weak social value submission is specificity:
- Weak: "We are committed to employing local people and supporting apprenticeships"
- Strong: "We target 30-40% local labour within 25 miles of the project site, tracked at operative level through our workforce management system. We currently employ 3 apprentices on structured 4-year programmes aligned to the EAL Level 3 Electrotechnical qualification."
Evaluate whether social value commitments are measurable, trackable, and backed by evidence from previous contracts. Aspirational statements without a tracking methodology will not deliver reportable outcomes during the framework period.
Delivery Evidence: Not Claims — Proof Points
Leicestershire Police: multi-site programme across a blue-light estate with 32% local labour, 180 apprentice hours, and documented social value metrics — the kind of evidence that scores highly in framework evaluation. See the full case study.
Red Flags in Contractor Submissions
Watch for these indicators of a weaker submission:
- Vague methodology — generic statements about quality and safety without specific processes described
- Missing accreditations — particularly NAPIT registration or appropriate insurance levels
- No case study evidence — or case studies that describe scope without measurable outcomes
- Aspirational social value — commitments with no baseline data, no tracking methodology, and no evidence from previous contracts
- Subcontractor-heavy workforce model — reliance on agency or subcontracted labour rather than directly employed operatives, which creates quality consistency and accountability risks
- No digital delivery capability — reliance on paper-based reporting, manual scheduling, and email-based document management
Employed Workforce vs Agency Models
The contractor workforce model has a direct impact on quality consistency across a framework. Evaluate:
Directly employed workforce: Operatives are employed by the contractor, trained to consistent standards, and accountable through the contractor management structure. Competency verification, DBS clearance, and H&S training are managed centrally. This model delivers consistent quality across sites.
Agency or subcontractor model: Operatives are sourced from agencies or subcontractors for each project. Quality standards vary between individuals, competency verification is harder to maintain, and accountability for workmanship is diluted. This model can work for simple, repetitive tasks but creates risk on complex or sensitive sites.
Ask contractors to state what percentage of their electrical workforce is directly employed. A contractor with 80%+ directly employed operatives will deliver more consistent quality than one relying primarily on agency labour.
Digital Delivery and KPI Reporting
Framework contracts increasingly require digital delivery capability and KPI reporting. Evaluate whether the contractor can provide:
- Real-time job tracking and progress reporting through a platform like Contracts OS
- Digital handover packs within a defined timeframe
- KPI dashboards showing performance against framework targets
- Centralised document management accessible to framework users
- Automated compliance reporting for multi-site programmes
A contractor with a structured digital delivery platform will provide better visibility, faster reporting, and more consistent documentation than one relying on manual processes. This is not a technology preference — it is a governance requirement for frameworks managing significant volumes of electrical work.
The evaluation process determines the quality of delivery your framework users will receive for the next 2-4 years. Investing time in rigorous assessment at appointment stage is significantly more cost-effective than managing poor performance during the framework period.
