The Home Index

Per-property compliance data and API for property professionals

The public The Home Index publishes aggregated statistics at postcode-district level and above. Pro is the planned professional layer — per-property data and a developer API — for teams that need to act on individual homes rather than area averages.

This product is in planning. Nothing here is for sale yet — register your interest below and help shape what we build.

What Pro is built for

The same per-property data, framed for the job you actually do.

Letting & estate agents

Run your landlord review at the property level. Every below-C property in a managed portfolio with its gap, modelled cost-to-C, and MEES 2030 position — as a client-ready PDF, not a spreadsheet. Know which landlords face the highest exposure before the review call.

→ Client reports · white-label

Brokers & lenders

Quantify energy risk in the loan. For each property: band, gap to C, modelled cost-to-C, and the matched-sale exposure signal — the inputs for affordability, LTV, and green-mortgage eligibility screening. Bulk API access for portfolio-level underwriting.

→ Risk data · API feed

Surveyors & assessors

Pre-survey intelligence before you open the door. The existing EPC assumptions, the modelled measures, the confidence rating, and the peer-cohort comparables for this property type and era — so you know what to verify on site.

→ Pre-survey brief

Installers

Find where demand is concentrating. Below-C density by postcode district, which measures suit which archetypes in which areas, and territory-level demand signals — the lead layer above the free public index.

→ Lead territories

The planned per-property dataset

We plan to extend the index down to the level of the individual dwelling: a per-property dataset combining a compliance-risk view — how far each home sits below EPC band C and its exposure to standards such as the Minimum Energy Efficiency Standard (MEES) for the private rented sector — with a retrofit-cost view, the modelled cost of bringing that specific home up to band C using the same documented per-band-gap cost model that powers the public index.

  • Compliance risk per property — current band, the band-C gap, and PRS / MEES exposure flags.
  • Modelled retrofit cost per property — the estimated investment to reach band C, labelled as a modelled estimate rather than a quotation.
  • Portfolio rollups — the same figures aggregated across a landlord, lender, or local-authority portfolio.

The planned API

Alongside the dataset we plan a developer API for professional users — lenders, landlords and managing agents, retrofit installers, surveyors, and local authorities — to query compliance risk and modelled retrofit cost for a property or a portfolio programmatically, and to integrate those figures into their own underwriting, asset-management, and planning workflows. Expect authenticated endpoints, bulk lookups, and the same transparent, documented methodology as the public index.
