The 3 Rules of Planning Maps
Why do councils reject maps? Usually, it's one of these three reasons. We handle them all automatically.
- 1 The Red Line Rule
Your site location plan must show the application site edged clearly in a red line. This includes all land necessary to carry out the development (access, gardens, etc.). If you own other land nearby, it must be edged in blue. Our tool lets you draw both effortlessly.
- 2 Scale & Direction
"About right" isn't good enough. You need specific scales: 1:1250 for location plans and 1:500 for block plans. Crucially, every map must clearly show a North point. We automatically generate compliant maps for planning permission with correct scales and orientation.
- 3 The Licensing Trap
Screenshots from Google Maps are copyright infringement and will be rejected instantly. You must use licensed Ordnance Survey planning maps. Our plans come with a valid license number clearly displayed, proving to the council you have the right to use the data.
Available Plan Sizes & Print Options
Choose the right scale, paper size, and printed-copy option for your project. All plans are OS MasterMap® accredited.

Site Location Plan vs Block Plan
When do you need a site location plan and when do you need a block plan?
Use a site location plan to show where the land sits in its wider setting. Add a block plan when the council also needs a detailed 1:500 site layout around the proposal.

What Makes a Planning Map Valid?
Local authorities reject up to 30% of applications due to map errors. Our system automatically enforces these 6 critical requirements.
Red Boundary Line
The application site must be edged clearly with a continuous red line. This defines the legal boundary of the development.
North Point
Every map must clearly indicate North. Ours are automatically oriented and marked.
Correct Scale Bar
Maps must be scalable. We include a precise graphical scale bar (e.g. 0-50m) on every PDF.

Common Questions About Planning Maps
Do I need both a site location plan and a block plan?
Most planning applications require both.
1. A Site Location Plan (usually 1:1250) to show where the property is located in the neighborhood.
2. A Block Plan (usually 1:500) to show details like boundaries, driveways, and the proposed works.
Check with your local planning authority or architect, but ordering one of each is the safest bet to avoid validation delays.
How long is my Location Plan valid for?
Planning authorities generally require maps to be created within the last 12-18 months. Using an old map runs the risk of rejection if new developments (like a neighbor's extension) aren't shown. Our maps are generated live from the latest Ordnance Survey database, ensuring they are always up to date.
Can I use an old map I found online?
Generally, no. Planning authorities require up-to-date mapping with a valid license. Many people search for an "ordnance survey map of my house" hoping to use an old deed or screenshot, but planning requires current OS MasterMap® data. Using unlicensed or outdated maps is the #1 reason for application invalidation.
Does the map show my property boundary?
The map shows the underlying Ordnance Survey topography (fences, walls, buildings). You must then add the "Red Line" to indicate your specific application boundary. Our easy-to-use tool lets you draw this red boundary (and any blue land-ownership boundaries) directly onto the map before downloading.
What file formats will I receive?
You will instantly receive your plans in PDF format (perfect for emailing to councils or printing). We also offer CAD formats (DWG & DXF) for architects and design professionals, allowing for easy editing in AutoCAD and other software.
What if I make a mistake drawing my boundary?
Reply to your order email and let us know what needs changing. Customer-input redraws are normally handled as a paid correction or a new order unless we choose to waive the fee.
Do I need a plan for Permitted Development?
Yes, usually. Even for Permitted Development, you typically need to apply for a Lawful Development Certificate to prove the work was legal. This application requires the same compliant Site Location Plan as a full planning application.
How detailed is the mapping data?
We use OS MasterMap® Topography Layer, which is the most detailed and accurate mapping dataset available in Great Britain. It shows individual buildings, correct footprints, fences, paths, hydration features, and road names.
