Research And Perspectives

Findings and perspectives on residential property and the evidence behind its value.

How Much Is the New-Build Premium?

A new flat selling for more than the average flat nearby does not tell us, by itself, how much buyers are paying for “new”.

They may also be buying a different location, a different specification or a different kind of building.

That distinction matters when interpreting new-build premiums.

Valuations

Why valuation models keep missing transformed houses

For altered homes, the history of how a property changed can matter as much as its current measurements.

Property Research

What is air conditioning worth to a UK home?

Cooling, solar generation and the property-specific question of energy performance.

Three valuation traps property people should watch for

Postcode averages, new-build evidence and the basis for choosing comparable properties.

Who Is Valtaic For?

The workspace is for landlords, owners, agents, advisers, property analysts, development and acquisition teams, and family offices working with residential property. The API is for SME lenders, proptech teams and engineers who need valuations within their own systems. Tell us what you need to assess or manage so we can discuss the relevant pilot scope.

Explore The Use Cases
How Do I Add Properties?

Open a portfolio, choose Add Property and search for the address. Save the record, then add details such as tenure, floor area, income and borrowing at your own pace. Discuss any existing records you want to bring across before the pilot.

See The Property Workspace

Data & Valuations

Workspace Or API?

Use the workspace for market data, portfolios, research and Agentic Analysis. Use the APIs to request valuations and market data from your own systems. Dataset access and valuation limits depend on your agreed access. The docs describe the endpoints and response formats.

Explore The Workspace
Can I Compare And Export Data?

Select an area, choose a measure and add another location to the chart. Adjust the period, inspect individual observations and download a CSV containing the selected area’s measures for that period. The comparison overlay is not included in the export.

See Area Comparisons
What Inputs Does The API Need?

Provide the property’s address and core characteristics, including tenure, occupancy, floor area and room counts. Requirements vary by property type; leasehold homes also need lease details. The API validates the property identity and inputs before returning an outcome. The documentation sets out the required fields and accepted values.

Read The Input Requirements
When Is A Valuation Referred?

The API returns a status that distinguishes an automated valuation from a referral, identity or validation outcome. Thin local evidence, missing information or an unsupported property can require further review. Your application should check that status before using a price, and route cases marked for manual valuation to a valuer.
