Last checked: 26 October 2026. Every PropertyData and Searchland fact below comes from that company's own website on that date. Where a site did not state something, the table says "not stated on site".
PropertyData, Searchland and Propalt all sell UK property data, and all three now connect to Claude and ChatGPT. They are built for different people. PropertyData leads with deal sourcing and analysis for investors. Searchland leads with land, planning and development. Propalt runs two products: prospecting software for estate and letting agents, and a property data API and MCP for professionals and developers.
If you are weighing a PropertyData alternative or a Searchland alternative, the right answer depends on the job. This page sets out what each platform says it does, then where each is the better fit.

What does PropertyData offer?
PropertyData is a web app with an API and MCP server behind it. The web app groups its tools into Research (local data, heatmaps, yield hotspots), Source (on-market search, unmodernised, repossessed, cash buyers only, HMO licensed, titles by company, letter sending) and Evaluate (Plot Map, valuation tools, construction costs, deal analyser, comparables, National HMO Register).
Web app plans run from Basic at £15 a month (20 credits) to Unlimited at £60 a month, excluding VAT, with 10% off for annual billing. One credit covers one search or valuation.
The API is sold separately, from 2,000 credits for £30 a month to 300,000 credits for £800 a month, and most endpoints cost one credit. The MCP server exposes 51 tools. PropertyData's AI page says it works on every Claude plan including Free, while ChatGPT needs a paid plan with developer mode. You sign in by OAuth, or use an API key for scripts.
Coverage caveats PropertyData states itself: its flood risk endpoint takes "an English postcode", and titles by company uses England and Wales land titles.
What does Searchland offer?
Searchland is a land and planning platform. Its MCP page lists seven data categories: planning applications (with comments, documents, appeals and building control), land and ownership (Land Registry titles, Price Paid, land values, VOA), local plan and policy (site allocations, SHLAA, Housing Delivery Test, TPOs), energy and grid (DNO substations and lines), people and companies (companies, directors, PSC), property use (HMO, EPC, schools, elderly care) and people and movement (transport, footfall, traffic, demographics).
Its API page describes planning applications as "Every UK application since 1990" and sold prices as England and Wales only, from Land Registry. Listings from Rightmove are refreshed weekly.
Pricing is licence-based. Standard starts from £195 a month paid annually for one user, with a 12-month minimum term. Pro adds strategic land data and residential comparables; MAX adds unlimited MCP tokens. Both are price on request. The API is a separate service; Searchland does not publish its price. Trials follow a demo with the sales team.
What does Propalt offer?
Propalt runs two products. Audience Builder on propalt.co.uk gives estate and letting agents 100+ filters to build prospecting lists, including Withdrawn, Sale Fallen Through, Reduction, Probate, Landlords, HMO Landlords, Short Leases and Lenders & Charges.
Around it sit My Prospects, which lists the landlords in an area with portfolio value, rental roll and status, and Success Centre, which matches your own new sale and rental listings against the letters you sent through Propalt. Each match is marked Exact or Broad with a High, Medium or Low impact level, so you can see which campaigns are followed by instructions.
propalt.ai is the data layer. The REST API at api.propalt.io includes /property/get-property, which returns UPRN, address, tenure, title numbers, property type, current energy rating and Propalt AVM for a UPRN, UDPRN or property ID. The MCP server works in Claude and ChatGPT. Pricing is a credit-based subscription.
One point to set expectations. The Propalt AVM is Propalt's own automated valuation, not a VOA or surveyor value.
Three platforms can draw on the same registers and still suit different buyers. Choose on the workflow, then check the coverage.
When is PropertyData the better fit?
When you are an investor or small developer sourcing deals and want a low monthly entry price with published plans. Its Source tools (repossessed, unmodernised, cash buyers only, HMO licensed) and deal analyser are built for that job, and its API pricing is fully published. If you want to self-serve without a sales call, PropertyData makes that easiest of the three.
When is Searchland the better fit?
When your work is land: site finding, planning history, local plan policy, constraints, or grid capacity for energy projects. Searchland's planning depth (applications since 1990 with documents and appeals) and its energy and grid layers go further into development work than the other two. The trade-off is a 12-month minimum term and a demo before a trial.
When is Propalt the better fit?
When you need agent prospecting tied to live market events (propalt.co.uk), or when you are a lender, broker, surveyor, conveyancer or PropTech team that wants property-level records keyed to the UPRN through an API or MCP (propalt.ai). Propalt's use-case pages for estate agents, conveyancers and mortgage brokers show those workflows. For the developer route, see UK Property Data API: The Complete 2026 Developer Guide.
Propalt does not list the local plan policy or grid capacity layers Searchland offers, or a deal analyser of the kind PropertyData offers.
What should you ask any UK property data platform?
- Which registers sit behind each field, and when did each last refresh? See our guide to UK property data sources for what each register holds.
- What share of sales records match to a UPRN? Our explainer What is a UPRN? covers why that join matters.
- What does Scotland and Northern Ireland coverage look like? PropertyData and Searchland both flag datasets on their own sites that cover England, or England and Wales, only.
- What does an MCP call cost? Credits, tokens or included, and what happens when the allowance runs out.
- What is the minimum term? Monthly rolling and 12-month terms are both on the market.

📌 KEY TAKEAWAY
PropertyData suits investors who want published, low-entry pricing and deal-sourcing tools. Searchland suits land, planning and energy work, sold on annual licences after a demo. Propalt suits agents who prospect from market events and professionals who want UPRN-keyed property records through an API or MCP. All three connect to Claude and ChatGPT, so the deciding questions are coverage, cost per call and contract terms. propalt.ai is built for teams that want to see the register behind every answer.
