Every Flood Layer Checked

Fluvial flood zones, surface water risk, flood defences, warning areas, main rivers and recorded historic flooding.

Red / Amber / Green Scoring

Every applicable layer is rated with a clear RAG risk score, explained in plain English for your exact site.

Instant PDF Download

Once paid, your branded flood risk report PDF is available to download immediately — no waiting.

What's Included in Your Flood Risk Report

Your flood risk report checks the site you draw against every layer in Maplify's fixed flood registry — including EA Flood Zones 2 and 3, flood storage areas, surface water risk at the 1 in 30 and 1 in 100 levels, flood defences, flood alert and warning areas, main rivers, and recorded historic flood extents. Each applicable layer gets its own page with a map, a red/amber/green risk score, a plain-English explanation of what it means for your site, and recommended next steps.

Flood Risk Search by Postcode

Instead of manually panning and zooming to find your site, search any UK postcode directly above the map and it will jump straight to that location. This makes it fast to run a flood risk search for a specific address, street or development site anywhere in the UK before drawing the exact boundary you want checked.

Flood Risk Reports for Planning Applications and Property Searches

Sites in or near EA Flood Zone 2 or 3 usually need a site-specific Flood Risk Assessment submitted alongside a planning application, and lenders or conveyancers will often flag flood exposure during a property purchase. This report gives you an instant, documented starting point — covering fluvial flood zones, surface water risk, flood defences, warning areas, main rivers and recorded historic flooding — so you know where you stand before commissioning a full assessment or proceeding with a purchase.

A screening tool, not a substitute for professional advice

This report is designed for early-stage flood risk screening. It does not constitute a formal Flood Risk Assessment — always confirm critical matters with the Environment Agency, a qualified flood risk consultant, or the relevant local planning authority.

Every Flood Layer Checked, and Why It Matters

Flood Zone 2 (Medium Probability)
A 1 in 100 to 1 in 1,000 annual probability of river flooding — usually triggers the Sequential Test and a site-specific Flood Risk Assessment.
Flood Zone 3 (High Probability)
A 1 in 100 or greater annual probability of river flooding — the most restrictive flood zone for new development.
Flood Storage Areas
Land engineered to hold floodwater during peak events — building here can remove flood capacity relied on elsewhere.
Surface Water Flood Risk (High — 1 in 30)
Risk from rainfall overwhelming drainage rather than rivers — often missed by fluvial-only checks but material to insurers and lenders.
Surface Water Flood Risk (Medium — 1 in 100)
A lower-probability surface water event still relevant to drainage design, SuDS and finished floor levels.
Flood Defences
Nearby defences that reduce (but don't remove) risk — their condition and standard of protection affects long-term reliance.
Flood Alert Area
Areas where the Environment Agency issues early flooding alerts — relevant to site access and emergency planning.
Flood Warning Area
Areas where flooding is expected and warnings are issued — a stronger signal than an alert area alone.
Main River (Nearby)
Proximity to a statutory main river affects consent requirements for any works near the watercourse.
Recorded Historic Flood Extent
Actual past flood outlines recorded by the Environment Agency — real-world evidence alongside the modelled flood zones.

Important Limitations

  • This report checks a fixed set of flood-related datasets for spatial intersection with your drawn boundary — it does not constitute a formal Flood Risk Assessment.
  • Drawn boundaries are capped at 20 acres; larger sites should be split into smaller sections.
  • Data is sourced from third-party Environment Agency datasets which Maplify does not control and cannot guarantee are complete, current or error-free.
  • A layer marked as not applicable reflects the result of this automated check only, not a formal search result.

Frequently Asked Questions

How do I order a flood risk report?

Search a UK postcode to find your site, click on the map to draw its boundary, click Finish Boundary, then fill in the details card that appears over the map — sign up when prompted, then pay £24.99 to instantly unlock your PDF flood risk report.

Can I search by postcode instead of drawing on the map manually?

Yes — enter any UK postcode above the map and it will jump straight to that location, so you only need to draw the boundary itself.

Is there a maximum site size?

Yes, drawn boundaries are capped at 20 acres. If your site is larger, you can split it into smaller sections and order a report for each.

What does the flood risk report cover?

It checks every layer in Maplify's fixed flood registry against your drawn boundary, including EA Flood Zones 2 and 3, flood storage areas, surface water risk, flood defences, alert and warning areas, main rivers and recorded historic flooding — each rated with a red/amber/green risk score.

Can I see a sample report before I pay?

Yes — the sample report on this page is an actual, unedited report generated by this tool, so you can see exactly what your PDF will look like.

When can I download my report?

Your report is generated after sign-up and can be downloaded instantly once payment is confirmed — there is no waiting or manual processing.

How much does it cost?

A flood risk report costs £24.99 per site and is a one-off payment — there is no subscription required.

Is this the same as a Flood Risk Assessment?

No. This is an early-stage screening report, not a formal Flood Risk Assessment. Always confirm critical matters with the Environment Agency, a qualified flood risk consultant, or the local planning authority.

Can I use this report to support a planning application?

It's a useful early screening document to identify flood constraints before you commission a formal, site-specific Flood Risk Assessment — which is usually what's required to accompany a planning application on a site within Flood Zone 2 or 3.

Does it cover surface water flooding as well as river and coastal flooding?

Yes — alongside EA Flood Zones 2 and 3, the report checks both high (1 in 30) and medium (1 in 100) surface water flood risk, which is often missed by fluvial-only flood searches.
