What V-Score is – and is not

V-Score is forensic planning risk intelligence. We read your entire submission to identify the vulnerabilities a rigorous planning officer, GLA reviewer, or inspector would exploit, before they do.

It is not a summariser. It does not index documents or produce generic overviews. It assesses risk. It does not advocate for or against development. It does not make legal determinations.

The central question V-Score answers is: on the evidence in these documents, where would a well-resourced and motivated officer find grounds to refuse, defer, or challenge this application?

Every finding is grounded in a specific document reference. Every score is explainable. Every recommended fix names who does it, when, and at what cost.

The analytical process

V-Score analyses applications in eight structured steps. The scoring stage does not begin until the cross-reference audit is complete. This is by design: most planning applications are defeated by internal inconsistencies, not by a single fatal policy breach.

Five scoring dimensions

Risk is assessed across five dimensions. Risks confirmed by independent or statutory bodies carry more weight than risks raised by the applicant alone.

Scoring and calibration

The score runs from 0 to 100. Base penalties are applied for each identified risk, credits are applied for genuine strengths, and a correlation adjustment is made where multiple penalties share a single root cause.

Score bands

The bands express where an application is exposed (what an officer could write and what would move the number), not a prediction of the committee's decision. Green (70–100): few exposed points; an officer would struggle to sustain an objection on the current evidence. Amber (50–69): material exposure an officer can articulate; identifiable changes would move the score. Orange (40–49): several lines an officer could write up, at least one standing on its own; addressable before submission. Red (20–39): multiple well-evidenced lines of objection; substantial rework needed to reduce exposure. Black (0–19): the evidence as it stands hands an officer a complete argument to refuse.

The correlation adjustment

The most common error in planning risk assessment is mechanical penalty stacking. Where a single design decision produces multiple failures, summing the penalties as independent would double-count a single cause.

The canonical example is the over-tall tower: the same extra height that causes WHS heritage harm is the same extra floorspace the FVA says is needed for viability. Summing those as independent penalties counts one design decision twice. V-Score identifies these correlation clusters, applies the highest single penalty in full, and applies 30–50% of each secondary penalty, with the adjustment documented in the report.

In the Whitechapel Campus (PA/26/00391), two clusters were identified. Cluster A (viability construction): four findings all serving one root cause – an appraisal built to confirm a deficit at 20% affordable. Cluster B (over-height as a single design choice): heritage harm, allocation breach, and townscape harm all arising from the same excess height. The correlation adjustment moved the mechanical score from 15 (Black) to 41 (Orange) – not to inflate it, but to prevent a single design decision from being counted four times.

How the viability audit works

Financial viability is the single most consequential dimension on complex schemes because it directly determines the level of affordable housing, the S106 obligations, and the public benefits used to justify harm. V-Score treats every FVA as adversarial until evidenced otherwise.

The Parkhurst Road test. Where the benchmark land value is derived from an Alternative Use Value that is itself a residual appraisal, the benchmark imports development hope value into the land cost – the circularity mechanism identified in Parkhurst Road Ltd v SSCLG [2018] EWHC 991. V-Score calculates the AUV as a percentage of the total benchmark and flags this as Critical when AUV constitutes more than 70% of the SVB.

Finance assumptions. RICS PS1 para 4.7 requires the finance assumption to reflect the applicant’s actual funding structure. A blanket 100% debt assumption at market rates for an institutional equity-funded applicant is presumptively unreliable. V-Score flags this as Critical and calculates the indicative RLV movement from rebasing to an equity-blended rate.

Derivation vs assumption. The correct RICS approach is to derive the maximum viable affordable percentage, not to adopt a figure and produce an appraisal that confirms it. Where a FVA states its starting point as a given affordable percentage and then confirms it – the assumed-percentage pattern – V-Score flags this as Critical.

Defensibility

Every score is defensible. If a planning partner or funder asks why the scheme scores 46 rather than 52, the answer is in the report: the specific findings that drove each penalty, the specific credits that offset them, and the specific reasons the mechanical score was or was not adjusted.

Report output structure

Every V-Score report contains eight sections in a fixed structure. The structure is the same across all scheme types: residential, PBSA, mixed-use, rural, industrial, EIA major.

Section 1 – Executive dashboard

One page. Score and band, three-line verdict, Critical risks only in a clearly marked panel, recommended client decision, and five immediate actions.

Section 2 – Risk summary table

All risks in a single table: risk factor, tier, type, penalty, curability, status. Mitigating factors credited in a footnote.

Section 3 – How the score is calculated

The score build, the correlation adjustment, the calibration note, and the specific reasons the score is not five points higher or lower.

Section 4 – Detailed findings

Every risk in tier order. For each finding: what was found (evidence, sources, figures), why it matters (policy basis, consultee positions), what the officer will say (written in first-person officer voice with real policy citations), and the recommended fix (named consultant type, timing, consequence).

Sections 5–8

Remediation roadmap with estimated costs, cost and consequence analysis (remediation versus contested refusal), documents to obtain before reliance, and methodology note with mandatory disclosures.

Limitations

V-Score is as complete as the document set supplied. Missing appendices, image-only PDFs, and incomplete submissions limit the analysis. Every data void is explicitly flagged in Section 7 of the report – documents to obtain before reliance.

V-Score identifies and quantifies planning risk. It does not predict planning outcomes with certainty. Planning committees can and do reach decisions that are not predicted by the policy framework. Local political factors, community objections, and committee dynamics are assessed where relevant but cannot be modelled with precision.
