Tender Quality Score

This is a well-structured preliminary market engagement notice, clearly outlining the scope for a future procurement of the National Calculation Methodology (NCM) services. While it provides good detail for market consultation, it lacks certain elements expected in a formal tender and exhibits a significant data inconsistency.

Score Breakdown

Legal Compliance80/100

As a preliminary market engagement notice, full legal compliance for a formal tender is not yet applicable. The notice provides reasonable time for market input, and the CPV code is appropriate. However, the absence of a defined procedure type for the future procurement is a minor transparency gap.

Undefined procedure type for future procurement
Clarity85/100

The description of the project, the role of BSR, and the scope of work for each of the three lots is exceptionally clear and unambiguous. The AI-extracted technical requirements accurately reflect the detailed description, providing a solid understanding of the anticipated needs.

Completeness75/100

The notice is largely complete for a preliminary market engagement, providing all essential basic information, estimated values, and durations. However, the lack of a specified procedure type and formal evaluation criteria for the future tender represents a gap in the overall procurement planning transparency.

Missing formal procedure type for future tender
Missing evaluation criteria for future tender
Fairness70/100

The disclosure of estimated values and reasonable time for market engagement contribute positively to fairness. However, the absence of specified evaluation criteria for the future tender reduces transparency for potential bidders. The lack of electronic submission support also presents a barrier to equal access.

No evaluation criteria specified for future tender
No electronic submission support
Practicality60/100

The contract start date and duration are clearly specified, and financing information is available. The primary practical drawback is the explicit lack of electronic submission support, which can hinder efficient participation for potential suppliers.

No electronic submission support
Data Consistency50/100

While dates are logical and no disputes are present, there is a significant data inconsistency regarding the estimated value. The overall estimated value is stated in EUR, whereas the individual lot values are provided in GBP, which is confusing and requires conversion.

Inconsistent currency for estimated values (overall EUR, lots GBP)
Sustainability40/100

The tender shows some focus on innovation, particularly in Lot 3 with the development of a cloud-based, user-friendly interface. However, there is no explicit mention of green procurement criteria or social aspects, representing a missed opportunity given the nature of energy performance calculation.

No explicit green procurement criteria
No explicit social aspects

Strengths

Clear and detailed description of project scope and lots
Reasonable timeframe for market engagement
Estimated values and durations clearly specified per lot
Good transparency regarding technical requirements
Innovation focus in Lot 3 for digital interface

Concerns

Inconsistent currency for estimated values (EUR vs GBP)
Lack of electronic submission support
Absence of specified evaluation criteria for the future tender
Missing formal procedure type for the future tender
No explicit green or social procurement criteria

Recommendations

1. Standardize currency for all financial figures to avoid confusion.
2. Implement electronic submission for the formal tender to enhance accessibility and efficiency.
3. Clearly define and publish the intended procurement procedure type and evaluation criteria in the formal tender documents.
