Benchmarks
Benchmark your projects against UK public-source data.
Method previews of the metrics NECCLAUSE will publish on UK NEC and infrastructure outcomes. Every figure is sourced; nothing is fabricated. Underlying datasets release only when the methodology can stand independent review.

Data that drives decisions
Benchmark your projects. Outperform your market.
Cards below preview the metrics NECCLAUSE benchmarks against public industry sources. Every figure is sourced — none is published until the underlying dataset is verified.

How NECCLAUSE benchmarks
Three principles. Plainly stated.
Principle 01
Sourced or labelled.
Every published figure is either drawn from a public dataset (cited inline) or clearly marked as a method preview / illustrative pattern. Nothing in between.
Principle 02
k-anonymity floor of 10.
Any benchmark that relies on contributor data publishes only when at least 10 distinct projects sit behind the figure. Below the floor, the dataset stays unreleased.
Principle 03
Independent of vendors.
Benchmarks are not co-published with consultancies, software vendors, or insurers. Outputs are not shaped by commercial relationships.
Sources we draw from
Public, citable, independently verifiable.
The benchmarks NECCLAUSE publishes draw from these public sources. Each link goes to the publisher; readers can replicate the figure end-to-end.
IPA Annual Report on Major Projects
Government Major Projects Portfolio (GMPP) data on schedule, cost, and benefits delivery across UK public capital programmes.
NAO investigations and lessons-learned reports
National Audit Office reports on individual major programmes — typically the deepest published commentary on what went wrong and where.
Ofwat regulated water reports
Performance commitments and outcome delivery incentives for AMP-cycle water infrastructure programmes.
TCC annual statistics
Technology and Construction Court published statistics on adjudication enforcement and substantive construction disputes.
ONS construction output
Office for National Statistics monthly construction output series — the macro context for any project-level benchmark.
