Searchland Property Data APIs

The Searchland API allows organisations to access Searchland’s national property and planning datasets programmatically, so the data can be used inside your own systems, dashboards or applications.

Rather than using the Searchland platform interface, an API allows developers to query specific datasets directly and retrieve the results automatically.

Typical use cases include internal analytics tools, custom development pipelines, or integrating property data into other software platforms.

Most organisations access Searchland data through the Searchland platform, which provides a visual interface for exploring planning data, ownership, constraints and land opportunities.

APIs are typically used when a company wants to automatically pull data into their own systems or applications, rather than using the platform directly.

If you simply want to source land, analyse planning activity or run site appraisals, the platform will usually be the better option.

No. API access is not included within standard Searchland platform licences.

A Searchland licence gives users access to the full platform interface, allowing them to visually explore planning data, ownership records, constraints and development opportunities.

API access is offered as a separate service for organisations that need to integrate Searchland data directly into their own software, databases or internal tools.

If your team simply needs to search, analyse and export data, the platform will usually be the most efficient option.

Searchland offers three main ways for organisations to access its datasets outside the platform:
‍
‍Bulk data downloads
Large national datasets delivered directly for organisations running large-scale analysis or building internal databases.
‍
‍API queries
A traditional REST API that allows developers to query Searchland data programmatically and retrieve results dynamically.
‍
‍GIS integrations
Direct integration of Searchland datasets into GIS software such as ArcGIS or QGIS, allowing spatial analysis alongside existing internal datasets.

Bulk downloads are typically used when an organisation needs large datasets covering the entire UK, rather than querying small pieces of data.

Examples include:
Building internal property or planning databases
Training machine learning models on property datasets
Running large-scale market analysis across the whole country

These datasets are usually delivered as structured files and are typically used by organisations with their own data infrastructure.

The API is best suited for organisations that want to retrieve specific data automatically within their own software or workflows.

For example:
Querying planning applications for a specific location
Integrating property data into an internal deal-tracking system
Building custom site sourcing tools
Enriching internal GIS or analytics dashboards

API access allows your systems to request data in real time without manual downloads.

Yes.

Searchland datasets can be integrated directly into GIS tools such as ArcGIS or QGIS, allowing your team to analyse planning and property datasets alongside other spatial layers.

This is commonly used by planning consultancies, infrastructure teams and research organisations that rely heavily on GIS workflows.

Yes - API integrations typically require a software developer or technical team.

The Searchland API is designed for organisations that want to connect Searchland data directly into their own software, internal tools, data pipelines or GIS systems.

This normally involves writing code to query the API, process the returned data, and integrate it into your workflows.

If your team does not have technical resources, the Searchland platform itself is usually the better option, as it already provides powerful tools for exploring planning, ownership and development data without any development work.

Searchland API access is typically priced based on monthly data credits, with annual contractual commitments.

Credits reset each billing cycle and do not roll over.

The API provides access to the same datasets that power the Searchland platform, including:

Planning applications and appeals
Planning documents and metadata
Land ownership and title information
Planning constraints and policy layers
Strategic land datasets (SHLAA, allocations, etc.)
Energy and infrastructure datasets
Sold price comparables

A simple rule of thumb:

‍Use the platform → if you want to search and analyse sites visually
‍Use the API → if you want your software to automatically request data
‍Use bulk API downloads → if you need large national datasets for internal databases or research
‍API / GIS integrations → if your team works primarily in bespoke spatial analysis tools

If you’re unsure, the Searchland team can help recommend the best approach based on your workflow.

Yes.

Searchland can provide a sample dataset or schema overview so your technical team can review the structure and confirm it fits your use case before integrating.

That’s completely fine - APIs can be complex.

To understand whether an API is the right solution, it’s important to have a clear idea of what data you need and how you want to use it. In many cases, the Searchland platform itself already provides the tools teams need to explore, analyse and export data without any technical setup.

The best way to work this out is to book a demo of the Searchland platform. During the demo we can walk through your use case, explore the data you’re looking for in the live platform, and help determine whether a platform workflow, API integration, or bulk dataset would be the best solution.
