Location plan vs site plan: key differences, scales, and UK planning requirements
Location plan vs site plan for UK planning permission explained. Learn required scales, red line and blue line boundaries, what each plan must show, and how to avoid validation delays.
One of the most common reasons planning applications are delayed is confusion between a location plan and a site plan. Applicants often upload one drawing thinking it covers everything, only to receive a validation request asking for missing documents. Knowing the difference can save days or even weeks during validation.
Both documents show your property on a map, but they serve different purposes. Councils use the location plan to understand where your site sits within the wider area. They use the site plan to understand exactly what is happening within your land boundary.
Quick comparison
- Location plan = wider context (streets, landmarks, neighbouring plots).
- Site plan (block plan) = detailed layout within your boundary.
- Location plan scale: usually 1:1250 or 1:2500.
- Site plan scale: usually 1:200 or 1:500.
- Both should show a red line boundary around the application site.
What is a location plan?
A location plan is a high-level map that shows your property in its surrounding context. It helps planning officers quickly understand where the site is, how it relates to nearby roads and buildings, and what surrounds it.
Location plans are usually required at a standard scale of 1:1250 or 1:2500. They must clearly identify the application site using a red line boundary and include enough surrounding area for context.
Location plan checklist
- Scale of 1:1250 or 1:2500 with a visible scale bar.
- Red line boundary around the application site.
- North point.
- Adjacent roads, buildings, and land parcels for context.
- Map copyright statement (typically Ordnance Survey based).
What is a site plan?
A site plan (sometimes called a block plan) is more detailed and focuses on what happens within the boundary of your land. It is used to understand access, layout, existing buildings, proposed works, and how your project fits within the plot.
Site plans are typically drawn at larger scales such as 1:200 or 1:500, allowing finer detail to be shown clearly. Councils use this drawing to assess practical issues like access, distances to boundaries, and relationships to neighbouring properties.
Site plan checklist
- Scale of 1:200 or 1:500 with a scale bar.
- Buildings, boundaries, access points, and parking.
- Distances to boundaries and nearby buildings where relevant.
- Existing vs proposed elements (clear labels or legend).
- North point and enough surrounding context to orient the plot.
What must appear on both plans
- Red line boundary (the application site).
- Blue line boundary if you own or control adjacent land.
- Correct scale and a readable scale bar.
- Clear labels and a clean, legible PDF export.
- No screenshots or raster images with blurred text.
Why councils require both
From the council’s perspective, these two drawings answer different questions. The location plan answers: Where is this development happening? The site plan answers: What exactly is happening on this piece of land?
Submitting only one of these plans often results in your application being marked as invalid. This triggers a validation request, which pauses the application clock until corrected documents are supplied.
Common mistakes that cause validation delays
- Uploading only a location plan and forgetting the site plan.
- Using the same drawing for both purposes.
- Missing red line boundary around the site.
- Incorrect scale or no visible scale bar.
- Submitting screenshots instead of clean exported PDFs.
- Using estate agent plans marked 'not to scale'.
Real example: why scale and purpose matter
A homeowner submitting an extension application used a single 1:2500 map for everything. While it clearly showed the house in its neighbourhood, it was impossible to understand where the extension sat within the plot. The council requested a separate site plan at 1:500 showing boundaries, distances, and layout. Once provided, validation passed immediately.
How to know which one you need
In most standard applications, you will need both a location plan and a site plan. Even small projects such as extensions, loft conversions, and outbuildings typically require both at validation stage.
If you are unsure, your council’s validation checklist will usually list both documents separately. Treat that as a strong signal that you should supply each as its own properly scaled drawing.
Pre-submission checklist
- Confirm scales: 1:1250 or 1:2500 for location plan; 1:200 or 1:500 for site plan.
- Add red line boundary and blue line boundary where applicable.
- Include a north point on both plans.
- Export as PDF and verify scale bars after export.
- Match your plan names to the council checklist (avoid generic file names).
Frequently asked questions
Is a location plan the same as a site plan?
No. A location plan shows the wider area around your property, while a site plan (block plan) shows the layout within your boundary. Most councils require both on the validation checklist.
What scales do councils accept in the UK?
Location plans are typically 1:1250 or 1:2500. Site plans are usually 1:200 or 1:500. Include a scale bar and always check your local validation checklist.
Do I need a blue line boundary?
Add a blue line if you own or control land next to the application site. If you only control the application site, a red line alone is usually sufficient. See how to draw a red line boundary.
Can I submit a screenshot from an online map?
Avoid screenshots. Councils expect clean, correctly scaled PDF plans with a scale bar and a copyright note where required.
What happens if I submit the wrong plan?
Your application is likely to be marked invalid and paused until you upload the correct drawings, which delays validation. See how to fix a rejected plan.
How Butler Floorplan helps
Butler Floorplan allows you to generate both location plans and site plans with correct scales, paper sizes, and calibrated outputs. Instead of guessing whether your map is suitable, you can choose the plan type, select the required scale, draw your boundary, and export a planning-ready PDF.
