Nimbus Maps is a site-sourcing and ownership-data platform for developers and deal sourcers, and its pricing is now quote-only. SiteLens is a self-serve UK planning-application alert tool from £0, or £29 a month billed annually (£39 monthly). They do different jobs, and this page helps you pick the right one.

Nimbus Maps is for the front of the property cycle: finding off-market land, checking who owns it and modelling whether a deal stacks up. SiteLens is for the back of the cycle: knowing the moment a planning application appears or is approved near you, so subcontractors, suppliers and trades can quote the work it creates.
SiteLens publishes its prices openly: £0 free forever with no card, and Pro at £29 a month billed annually (£39 monthly). Nimbus Maps no longer lists prices on its own pricing page. Its Plus, Advanced and Enterprise tiers are quote-only, so you contact sales for a figure. You can start SiteLens today without a sales call or a contract.
SiteLens reads every new planning application across 380+ UK councils and classifies it by trade, project type and an estimated value band, then writes a plain-English brief. Daily email alerts are filtered to your trade and area. Nimbus does not classify applications by trade or value band for the construction supply chain. Its planning data supports site appraisal, not lead generation for contractors.

A developer or deal sourcer can run both. Nimbus Maps does the acquisition work: finding off-market sites, checking ownership and title, and modelling whether a scheme stacks up. SiteLens then watches the live planning register so you, or the trades and suppliers you work with, get new applications and approvals in your patch in the daily alert. One sources the site, the other surfaces the work the site creates.
Nimbus Maps no longer publishes prices on its own pricing page. Its Plus, Advanced and Enterprise tiers are quote-only, so you contact sales for a figure. That was the position on its own pricing page as at August 2026. SiteLens publishes its pricing openly: £0 free forever, or £29 a month billed annually (£39 monthly).
No, and it is honest to say so. Nimbus Maps is a site-sourcing and ownership-data platform for finding and buying property. SiteLens is a planning-application alert and classification tool for the trades and suppliers who want the work that follows planning approval. They do different jobs, and many users in property will benefit from both.
No. SiteLens does not include land ownership, title or comparable-sales data, and it has no site-sourcing or owner-letter workflow. It focuses on live UK planning applications across 380+ councils, classifying each one by trade, project type and estimated value band, and sending daily alerts filtered to your area.
If your job is to find and acquire land, Nimbus Maps does things SiteLens deliberately does not. It brings ownership and title lookups, more than 30 million comparable sales data points, off-market site-finding filters and parcel-level constraint mapping into one place, and it lets you run direct-to-vendor letter campaigns to canvass owners at scale. SiteLens flags planning constraints on live applications, but it has no ownership, comps or letter-campaign tooling, and is not trying to.
For developers, deal sourcers, surveyors and planners who live in site appraisal and acquisition, that depth of ownership and market data is the whole point, and it is worth the higher price and the longer term. SiteLens is a focused planning-alert tool for the people who win work after planning is granted, not a replacement for a sourcing platform.
