Planning constraints map
Understand the designations and restrictions that may shape a development proposal, then explore each relevant layer in detail.
Land intelligence platform
UK land intelligence for confident site decisions
Search any site and see planning, flood, ownership and environmental constraints on one interactive map — 265+ official UK data layers in an instant.
Map search
Explore by search
Enter a postcode, address, place, grid reference or Land Registry title number to jump straight to that location on the Maplify map and switch on the data layers you need.
Maplify is a screening and due-diligence tool. Verify critical planning, legal and environmental matters with the relevant authority or qualified professional.
Explore by search intent
What would you like to check about a site?
Start with the topic that matters to your property or project. Each area links directly to a dedicated map, tool or detailed guide.
Flood risk maps and checks
Investigate river, sea and surface-water flood risk early in the site selection process. A map is a starting point, not a substitute for a site-specific flood risk assessment.
Land ownership and boundaries
Locate registered title information and explore mapped property boundaries. Treat general map outlines as indicative, and verify legal boundaries against title documents.
Planning permission and applications
Explore planning permission requirements, nearby applications and planning history before deciding on a proposal or instructing a consultant.
Environmental and heritage constraints
Review the natural and historic environment around a site, including protected habitats, protected trees, designated buildings and potential land contamination.
Development site due diligence
Build an evidence-led initial site assessment by reviewing planning policy, physical risk, access, infrastructure and ownership information in context.
Maplify's free community initiative
Help your community put local flood knowledge on the map.
Our free Community Flood Mapping Project helps flood action groups combine Environment Agency flood layers with local knowledge about drainage issues, historical flooding, refuge points and potential dry routes. Build and share a map that your community can understand.
View-only project links can be shared freely. Editing a group map is restricted to authorised group members. For emergency decisions, follow official flood warnings.

UK land intelligence
Planning constraints, flood risk and land information — connected in one place
Whether you are buying a plot, preparing a planning application or screening a development opportunity, the first question is often the same: what could affect this site? Maplify helps you explore location-based land information on an interactive map and move from a broad site search to more focused checks.
Review planning designations, investigate environmental risks, explore ownership and boundaries, and find the reports and guidance relevant to your next decision. Different datasets cover different geographies and dates, so always check the original source and obtain professional advice where appropriate.
A more informed first assessment
How to check planning constraints on land
A useful planning constraints check is more than a single coloured overlay. Take a repeatable approach, and separate preliminary screening from formal due diligence.
1. Locate the site
Search an address, postcode or location in the interactive map. Establish the site boundary and surrounding context before drawing conclusions.
Open the interactive map →2. Examine relevant constraints
Switch on planning, flood, heritage, ecology and infrastructure layers to identify issues worth investigating further.
Explore map data layers →3. Verify with primary sources
Check the applicable local planning authority, original datasets, dates and any supporting documents. Map overlays can be incomplete or change over time.
Find a planning authority →4. Document your findings
Use a checklist or a report to organise initial findings, record outstanding questions and brief the right professional advisers.
Browse site reports →Important: Mapping and screening tools do not determine whether planning permission will be granted, confirm exact legal title boundaries, or replace official property searches and professional surveys.

Questions about Maplify and UK land checks
Can UK flood action groups create and share free community flood maps?
Yes. The Maplify Community Flood Mapping Project brings together published Environment Agency flood layers and local knowledge such as drainage issues, historical flood points and possible dry routes. Authorised group editors use an assigned code, and residents can open view-only project links for free. Community information does not replace official flood warnings.
What is land intelligence?
Land intelligence is the combination of planning, ownership, environmental, infrastructure and market data that lets property professionals understand the true potential and risk of a site before committing time or money. Maplify brings all of this together in one Land Intelligence Platform.
How do I identify development land?
Use Maplify's site discovery tools to search any UK location and instantly see ownership, planning designations, flood risk and infrastructure constraints, helping you shortlist genuine development opportunities faster.
How do I check planning constraints?
Search a postcode, address or grid reference on the Maplify planning constraints map to see Green Belt, conservation areas, listed buildings, Article 4 directions and local planning designations for any site.
How can I assess development opportunities?
Maplify overlays planning history, ownership, environmental risk and market data on one map so you can assess a site's development potential in minutes rather than days of manual due diligence.
What data does Maplify include?
Maplify includes Land Registry boundaries and ownership, planning applications and designations, flood risk, heritage and ecology constraints, ground and geology risk, utilities and infrastructure, and market comparables — sourced from public authorities and other data publishers, with coverage varying by layer.
Who uses Maplify?
Maplify is used by property developers, housebuilders, planning consultants, architects, surveyors, land promoters, utilities providers, renewables developers, local authorities and investors across the UK.
Is Maplify suitable for developers?
Yes. Maplify is built specifically for developers and housebuilders to reduce site risk, find better opportunities and accelerate due diligence with live planning and environmental intelligence.
Can I export reports?
Yes. Maplify lets you generate professional site feasibility and block plan reports directly from the map, ready to share with clients or colleagues.
Does Maplify include ownership data?
Yes. Maplify integrates HM Land Registry title and ownership data, including company ownership records, alongside every other layer on the platform.
Can I search by postcode?
Yes. You can search any UK postcode, address, OS grid reference or Land Registry title number to instantly locate a site on the map.
How much does Maplify cost?
Maplify offers a free tier to get started, with paid plans for teams needing higher usage limits, report exports and additional data layers. See our Pricing page for full details.
Does Maplify replace a solicitor or planning consultant?
No. Maplify is a screening and due-diligence tool that surfaces official data quickly, but it does not replace professional legal, planning or surveying advice. Always verify critical matters with a qualified professional or the relevant local planning authority.
How current is the planning and environmental data?
Maplify brings together published data from HM Land Registry, the Environment Agency, Natural England, Historic England, local authorities and other sources. Publication and refresh dates vary by layer: verify significant findings against the source record.
Can I use Maplify on mobile?
Yes. Maplify is fully responsive and works on desktop, tablet and mobile, so you can check planning constraints and site intelligence on a site visit as well as at your desk.
