Every platform demos well. That's the problem.
You book the walkthrough, watch a confident salesperson click through a polished interface, and by the end everything looks broadly the same: a map, some layers, an ownership lookup, a planning feed. On the surface, the major land and planning platforms are hard to tell apart. The differences don't show up in the demo. They show up three weeks later, on a wet Tuesday, when you're trying to do real work and the tool either gets out of your way or fights you at every step.
So the question isn't which platform looks best? It's which one will actually hold up day-to-day? - and the only way to answer that is to push on the same set of questions for every platform on your shortlist. Not the questions a salesperson wants to answer. The ones that matter once the contract is signed and you're using the thing for hours every day.
Here are ten worth asking. Ask them of everyone you're considering. Ask them of us.
1. Can I click a site and instantly see everything that affects it?
The real test of a due diligence tool is what happens the moment you select a title. Do the constraints that affect that specific site appear together - flood zone, Green Belt, conservation area, listed buildings, TPOs, Article 4, adopted roads - or do you have to remember which layers to switch on and hope you didn't forget one?
That distinction matters because a missed constraint is a dead deal or a wasted appraisal. A platform that relies on you remembering to toggle the right layers is a platform that will eventually let you miss something. Look for everything surfacing automatically, in one panel, the same way every time - regardless of who on the team is logged in.
2. Can I describe what I'm looking for in plain English?
Most sourcing still means wrestling a filter panel. You have to know, up front, exactly which combination of size, use class, planning history, owner type and proximity will surface the sites that match your strategy. Get one wrong and you miss every relevant site - without ever knowing you did.
The practical cost of this is trust. Junior team members never quite believe their searches, and senior staff end up redoing the work. Ask whether you can simply state the brief in your own words and have the platform build the search for you. It's the difference between senior-partner-quality sourcing being available to everyone on day one - and being locked behind years of knowing which boxes to tick.
3. Does the platform turn market data into real numbers?
A list of properties for sale is not market intelligence. It's useful for browsing and little else. What a developer or surveyor actually needs is the maths done first: average £/sqft for this postcode, sold-versus-listed velocity, a five-year price trajectory, rental yields - pre-computed and sitting on the site card, not waiting for you to export it into a spreadsheet.
The question to ask is blunt: what's the average £/sqft for this postcode? If the platform can answer that instantly, it's doing the work. If it hands you a list of listings and leaves the arithmetic to you, you've bought a directory, not an analytics tool.
4. Does it turn planning data into approval rates?
The same test applies to planning. There are nearly 24 million planning applications and half a million appeals on record. Most platforms give you the list. Far fewer give you the numbers that decision-making actually depends on - the approval rate by application type, the decision-time trend, the year-on-year shift, per LPA.
When you're advising a client on how a particular council behaves, "what percentage of new-flat applications does this authority approve?" is the question that matters. You want that as a figure on screen, not something you reconstruct by reading through case after case.
5. Can I read every planning document inside the platform?
This one sounds minor until you've done it fifty times. If assessing an application means leaving the platform, opening a council portal and downloading a PDF for every document, that's a tax on every piece of due diligence you do. It adds up to hours a week and breaks your concentration every time.
Ask whether planning documents open inside the platform itself. The ability to read every document where you're already working - rather than bouncing out to a portal - is one of those things you don't notice you're missing until you stop doing it the hard way.
6. Is everything in one place?
Plenty of "platforms" are really three or four products stitched loosely together: a dashboard here, a planning map there, a separate strategic-land tool, an ownership search somewhere else. Every jump between them costs time and fragments your single source of truth on a site.
The test is whether sourcing, due diligence, ownership, comparables, outreach and analysis all live on the same workspace - one map, one record per site. A scatter of tabs isn't a workflow; it's four subscriptions wearing a trench coat.
7. Can I see the full company tree behind an owner?
You find a promising title, and it's held by a thinly-named SPV. On a lot of platforms, the trail stops right there. You don't see the directors, the parent group, or the other seventeen sites the same family or company controls - and so you miss the strategic deal hiding behind the shell.
Ask whether the platform surfaces the full corporate tree: parents, subsidiaries, directors, PSC register, every related title. Clicking an SPV and seeing the entire landholding behind it is often where the best opportunities actually live.
8. Can I send personalised letters to landowners - tracked - without leaving the platform?
Building the long list of owners is the easy part. The grind is drafting, printing, posting and tracking a few hundred personalised letters through a separate mail-merge tool - which can eat a full day per campaign, and produces generic letters that convert poorly.
The question is whether outreach is built in: personalised letters drafted in your voice, sent from the platform, with every reply tracked back against the original site. Done properly, this is also direct-to-vendor — no agent's 1–2% fee standing between you and the owner.
9. When I ask the AI a question, is it grounded in live data?
Every platform has an AI feature now, and it's become fashionable to wave them off as glorified writing aids - fine for drafting, not to be trusted with facts. That caution is right for one kind of AI: the kind that improvises from a stale, cached snapshot and hands you a confident, plausible answer that happens to be wrong.
But the problem there is grounding, not AI itself. Wire the model directly into live data - as Searchland does through its Model Context Protocol (MCP) connection - and it stops guessing entirely. Ask for brownfield sites under two acres with a particular ownership profile, and it runs the search across live titles, returns ranked candidates, and tells you exactly which datasets it queried and the figures behind each one. It isn't writing prose that sounds true; it's reporting what the data says and showing its working. Plugged into the right data, the AI becomes a source of verifiable truth - and that distinction is the whole game, because it's the difference between an answer you can act on and one you have to second-guess.
So the question isn't "does the platform have AI?" Everyone will say yes. It's "when I ask it something, is it reading live data - and can it show me?" If it can, you've got verifiable answers at conversational speed. If it can't, you've got a chatbot.
10. Will I have a dedicated person who knows my business?
The worst feeling with software is having no-one to call. Plenty of platforms hand you a login, point you at the help docs and wish you luck. When something breaks or you're not sure how to do something, you're logging a ticket and waiting.
Ask whether you get a named person from day one - someone who learns your team, your strategy and the outcomes you're chasing, who trains your people, answers them directly and stays with you. The honest version of this question is: if I have a problem on a live deal, is there a human who knows my business, or a help-desk URL? The answer tells you whether you're buying software or hiring a partner.
Use this as your scorecard
Use these ten questions. Take them into every demo on your shortlist and score each platform the same way - ours included. The point isn't to find a tool that scores ten out of ten on a feature sheet; it's to find the one that holds up on the work you'll actually be doing every day.
One last tell worth noticing: which platforms are willing to put their weaknesses next to their strengths and invite you to ask the same of everyone? A platform confident enough to hand you the scorecard is usually the one that has the least to hide.
