Geographic Eligibility

Many funds are restricted to specific geographic areas — perhaps a local authority, a region, or within a certain distance of a location. Plinth lets you define these boundaries visually and automatically screen applicants based on where they're located.

Why Use Geographic Restrictions?

  • Target your impact — Focus funding where it's needed most

  • Meet funder requirements — Many funders restrict grants to specific areas

  • Automatic screening — Applicants outside your area are filtered automatically

  • Clear communication — Visual maps help applicants understand if they're eligible


Three Ways to Define Your Area

When setting up or editing a fund, go to Step 4: Funding Preferences and find the Geographic Restrictions section.

Option 1: Radius from Point(s)

Best for: Funding within a certain distance of one or more locations.

How to set up:

  1. Select Radius from point(s)

  2. Click on the map to add a point, or search for a postcode

  3. Set the radius (distance) from that point

  4. Choose the unit (miles or kilometres)

  5. Add more points if needed

How it works: Applicants are eligible if they're within the radius of ANY of your points. This is useful when you want to cover multiple areas that aren't contiguous.

Example: "Within 10 miles of Manchester or Liverpool" — add two points with 10-mile radii.

Option 2: Boundary Area

Best for: Funding within defined administrative boundaries.

How to set up:

  1. Select Boundary area

  2. Search for your region (local authority, county, etc.)

  3. Select the boundaries you want from the results

  4. Add multiple boundaries if needed

How it works: Applicants are eligible if their postcode falls within ANY of the selected boundaries.

Available boundaries:

  • Local authorities

  • Counties

  • Regions

  • Parliamentary constituencies

  • And more...

Example: "Organisations in Birmingham or Solihull" — select both local authority boundaries.

Option 3: Draw Custom Shapes

Best for: Areas that don't match standard boundaries.

How to set up:

  1. Select Draw custom shapes

  2. Click Start drawing

  3. Click on the map to create points for your polygon

  4. Double-click to complete the shape (minimum 3 points)

  5. Draw additional shapes if needed

How it works: Applicants are eligible if their location falls within ANY of your drawn shapes.

Example: A specific neighbourhood, a park catchment area, or a custom region that crosses administrative boundaries.


How Geographic Checking Works

For Applicants

  1. Applicant enters their postcode in the application

  2. The system converts this to coordinates

  3. For radius: Calculates distance to each point

  4. For boundaries/shapes: Checks if location is inside any polygon

  5. If outside all areas, the applicant is shown as ineligible

For Portals

If you're using funding portals with eligibility screening:

  • Geographic checks happen as part of the screening process

  • Applicants outside your area see a "not eligible" message

  • You can customise this message to suggest alternative funds


Displaying Geographic Information

Maps in Your Fund Setup

When you configure geographic restrictions, you'll see:

  • Interactive map — Shows your defined areas

  • Radius circles — Visual representation of distance from points

  • Boundary polygons — Shaded areas for selected regions

  • Your drawn shapes — Custom polygons you've created

Maps for Applicants

Geographic eligibility checking happens automatically when applicants enter their postcode. The system checks their location against your defined areas and shows eligibility results, but maps are not currently displayed to applicants in portals or application forms.


Tips for Geographic Restrictions

Be clear about what "location" means

Decide whether you're checking where the organisation is based, where they deliver services, or where beneficiaries live. Make this clear in your eligibility criteria.

Consider edge cases

Organisations near boundaries may deliver services on both sides. Decide how strict you want to be.

Use radius for flexibility

Administrative boundaries don't always match community needs. Radius from key locations can be more meaningful.

Combine with other criteria

Geographic eligibility works alongside other screening questions. An applicant must meet all criteria to be eligible.

Test your setup

Enter a few postcodes from inside and outside your area to make sure the checking works as expected.


Changing Geographic Restrictions

You can update geographic restrictions at any time:

  1. Go to your fund's Set-up tab

  2. Click Edit Fund

  3. Navigate to Step 4: Funding Preferences

  4. Modify your geographic settings

  5. Click Save Changes

Note: Changes affect new applicants immediately. Applications already in progress are not re-checked.


Frequently Asked Questions

Can I have multiple non-contiguous areas?
Yes. Add multiple radius points, select multiple boundaries, or draw multiple shapes. Applicants in ANY of your areas are eligible.

What if an applicant's postcode isn't recognised?
They may need to enter a nearby valid postcode. Very new postcodes sometimes take time to be added to mapping systems.

Can I change from radius to boundary mode?
Yes. Select a different mode and configure it. Your previous settings are replaced.

How accurate is the checking?
Postcode-level accuracy. In the UK, postcodes typically cover a small area (average 15 households), so this is usually sufficient.

Can applicants appeal geographic decisions?
That's up to you. Consider adding contact information in your "not eligible" message for edge cases.

Does this work internationally?
The system works best with UK postcodes and boundaries. For international funds, radius-based restrictions with coordinates work anywhere.
