The Challenge
A price control review ties up a hundred people for two years and one unevidenced claim can be disallowed for the period. Costs, asset records and commitments sit across three functions with no shared trail.
How It Works
- Reads cost ledgers, asset registers, business plan commitments and past Ofgem determinations.
- Ties every allowance claim to its source records and to the determination that supports it.
- Gives the regulatory lead a cited submission draft and drafted Ofgem query replies each week.
What It Removes
- Manual sourcing of evidence for each cost claim
- Re-answering the same Ofgem information requests
- Version chaos across submission drafts
Input Data RequirementsCost allocation ledgers, asset registers, business plan commitments, prior RIIO submissions, Ofgem determinations and information requests
Output FormatSubmission draft with a source citation behind every figure, an Ofgem query response log, and a claim-by-claim disallowance exposure register
“Every number in the submission has to be defended and we spend the year finding out where each one came from”
