Key takeaways

Six conclusions to carry forward

What this evidence base reliably supports, where it needs cross-checking, and the actions that follow.

01

Ownership can be proven, not just inferred

Registered title records gave a first-party, conclusive proprietor confirmation: far stronger evidence than the address, applicant or agent signals that dominate every other dataset. Any decision that turns on who owns what should start here.

02

Location on an estate's street is not attribution

Across two estate searches totalling 69 relevant records, the overwhelming majority were filed by tenants, agents, leaseholders and building-specific companies. Only a handful were the estate itself. Activity tracking built on address matching overstates reality.

03

Currency varies enormously, and not visibly

Applications and appeals refresh daily with a one-day lag. Policy layers can sit frozen for two years or more per authority. Several dates that looked live measured crawl time, not content time: a distinction that changed the answer repeatedly.

04

Records are not schemes, and labels are not scale

Deduplication turned 26 records into 23 schemes, and a 'non-material amendment' carried 29 additional homes. Volume metrics taken straight from a record count will be wrong in both directions.

05

The strongest evidence sits in four places

Planning applications, registered titles, energy certificates and substation headroom produced the most reliable, decision-useful results. Proxies: rateable value for rent, static footfall for activity: are genuinely useful but must be labelled as proxies.

06

Know the boundaries before you commit to a question

No official multi-domain deprivation indices, no pre-2021 census comparison, no signed lease figures, no date-scoped footfall and no reliable vacancy indicator. Framing questions around what the evidence can actually carry avoids expensive dead ends.

Evidence strength

Four sources carried the weight

These produced the strongest, most reliable results. Proxies remain useful, but must be labelled as proxies.

Planning applications

Live, deep and comprehensive across 380+ official authority portals, with verified history back to 1983.

Registered titles

The only conclusive ownership evidence available, with 208 fields and cross-links to energy, rating and licensing records.

Energy certificates

124 fields per certificate, giving portfolio-wide minimum-standards and retrofit risk exposure.

Substation capacity

Direct, quantified answer to whether an electrification programme can physically be connected.

Proxies, clearly labelled

Rateable value is an official valuation for tax purposes, used here as a rent proxy. Pedestrian counts are modelled, static and directional. Income figures come from a 2020 model with a confidence range. Each is genuinely decision-useful; none should be presented as a measured transaction or observed count.

Recommended actions

Where to apply this next

01

Establish ownership from the register first

Before any approach, assembly or joint venture conversation, run the holdings through registered titles. Everything else is inference.

02

Rebuild activity tracking around named evidence

Replace address-matched landowner monitoring with applicant, agent and document-level confirmation. The current picture overstates estate activity by a wide margin.

03

Screen the portfolio for retrofit and capacity exposure

Combine energy certificate ratings with local substation headroom to identify assets where a retrofit-first policy position collides with a physical connection constraint.

04

Read consultation history, not just live cases

Comment text is thin on the newest applications but rich historically. Profile the bodies that will respond, and the policies they cite, before submission.

05

Date-check every policy layer before relying on it

Where a policy snapshot is frozen, confirm the current adopted position externally and label it as such in any output.

06

Frame questions to the evidence available

No official multi-domain deprivation indices, no pre-2021 census comparison, no signed lease figures, no date-scoped footfall, no vacancy indicator. Design analysis around those boundaries.
