Findings
Plota is ahead of SearchLand by 9,452 unique visitors, about 77 per cent, and leads on deduplicated audience by a similar margin. Below the top three the index falls away: LandCycle on 9,352, Nimbus Maps on 4,196 and LandHawk on 967. For context, the construction intelligence platforms Glenigan (13,346) and Barbour ABI (6,891) sit outside the comparison and below Plota.
Plota also passed 85,000 visits in September (GA4).
Nimbus Maps sees the most pages per visit of the six, about 23 on Similarweb’s figures.
Scope
The index covers UK platforms where searching for planning applications, land or potential development sites is a core part of the product. It includes land sourcing and site sourcing platforms and planning data software, provided planning data forms a substantial part of what a user is paying for.
Twenty-seven UK planning and land sites are tracked for this index, four of them below Similarweb’s reporting threshold. The six ranked here are the largest land sourcing and planning data platforms among them by audience.
Method
Unique visitors is Similarweb’s estimate of how many different people reached the site in the month. Deduplicated audience is its estimate of those people net of the same person arriving on more than one device.
Each figure covers the whole website, including its subdomains, such as a platform’s logged-in app, across desktop and mobile web in the UK.
The index is published monthly on the same domains and the same two metrics, so the readings can be compared over time. Each edition keeps its own dated address.
Limitations
Similarweb figures are modelled estimates, not first-party analytics, and each company’s own numbers will differ. They are used here because one method applied to every domain allows a like-for-like comparison, which no company’s own analytics can offer.
Similarweb is the most widely cited third-party source for this measurement. SparkToro compared four traffic tools against the Google Analytics figures of 641 websites and found Similarweb’s estimates closest to the real numbers.
What are the best UK land sourcing platforms in 2026?
LandTech
Best for: Site assessment and appraisal
Property development software built around land search and site appraisal, with broad top-level layers and a lot of data bundled underneath each one. Our layer comparison put it at around 21 constraint and environmental overlays. Habitat networks, nature recovery projects, priority habitats and the Ancient Tree Inventory sit under its biodiversity layer, and it carries topography, rights of way, water neutrality and safeguarded sites alongside the planning constraints.
Plota
Best for: Planning and land data infrastructure for existing systems and workflows
Plota provides a single API for normalised UK planning and land data, covering every planning authority across all four UK nations and updated daily. Planning records are linked to company freehold ownership, sale prices, site constraints, related application chains and committee decisions.
Organisations can bring the data into their own products, models and workflows, rather than moving users into a separate platform. The same underlying data powers Plota itself.
Nimbus Maps
Best for: Comparables and owner outreach
A property intelligence platform covering commercial and residential stock, with a comparables tool the company describes as drawing on more than 30 million comparables, ownership lookup and contact at scale.
LandCycle
Best for: Ownership mapping without a subscription
A land data platform built on Land Registry titles, turned into an ownership map with colour coding by owner type, price paid, energy certificates and a letter-writing service for approaching owners. The company publishes it as free to sign up with no licence fee, which makes it the obvious first stop for occasional ownership questions.
SearchLand
Best for: Teams wanting an end-to-end land sourcing workflow in one platform
A broad land sourcing platform that brings ownership, planning history, constraints, site search, appraisal and owner outreach into a single interface. SearchLand is well suited to teams that want users working through a defined sourcing and assessment workflow within one platform, with access typically organised around individual user seats.
LandHawk
Best for: Parcel search at scale, and renewables
Site finding software: geospatial land search across more than 150 datasets, built around defining suitability criteria and running them over large areas rather than looking up one site. The company names solar, battery storage and onshore wind developers among its users. It has been owned by Idox since 2022.
Questions
What are the best UK land sourcing platforms in 2026?
The six compared here are Plota, SearchLand, LandTech, LandCycle, Nimbus Maps and LandHawk, drawn from 27 UK planning and land sites tracked for this index. They are built for different jobs, so there is no single best one: LandTech is strongest on appraisal, Nimbus Maps on comparables and owner contact, LandCycle on ownership mapping, LandHawk on parcel search at scale, and Plota on planning and land data infrastructure for existing systems and workflows.
Which UK LandTech platform has the largest website audience?
Plota. Similarweb estimated 21,726 monthly unique visitors and a deduplicated audience of 19,383 in September 2026, ahead of SearchLand on 12,274 and LandTech on 12,081.
What software do property developers use to find development land?
Land sourcing software works from ownership and constraints rather than from listings, which is how off-market development land is found: who owns a parcel, what constrains it, and how to reach the owner. A search that has to cover a whole region, and run again every month, ends up in a firm’s own system rather than in any one product’s interface, which is why an API matters as much as the screens do. Among the platforms here LandHawk runs suitability criteria over large areas, Nimbus Maps and LandCycle start from ownership and contact, and Plota supplies the planning and land data underneath, through one API into a firm's own systems: what has been applied for nearby, what the council decided, who owns the land and what constrains the site.
