London governance repository assurance: from board decision to Ofgem-readable evidence

Five owned stages carry an LGD board decision from capture through assurance to a filed evidence pack, and each stage hands the next a specific artefact the regulator expects to see.

The assurance model lets Ofgem read LGD board decisions without LGD legal in the room. Each stage produces one named artefact, and the pipeline terminates in the regulator-readable section of the repository.

London governance repository assurance: from board decision to Ofgem-readable evidence A vertical five-stage pipeline with a left axis pointing down, labelled decision to evidence. Each stage names its owning function as a left chip and the artefact it hands on as a right tag, with downward flow arrows between stages. Stage 1, the architecture board, captures the decision as a board minute. Stage 2, the repository team, categorises it into a tagged record. Stage 3, internal audit, checks it against principle and standard, producing an audit finding. Stage 4, the secretariat, assembles the assurance pack. Stage 5, marked in red, files the evidence in the regulator-readable repository. A red note states the pipeline lets Ofgem read board decisions without LGD legal present.
