🧭 Route Intelligence

Determine the right consent route: permitted development, prior approval, full planning, LDC, or EIA.

💡

Use these tools to determine whether you need planning permission and which type of application to submit. Getting the consent route wrong wastes time and money. Check PD rights first, then consider whether prior approval or full planning is the better option.

✅

PD Rights Checker Popular

Check if your proposal falls within the General Permitted Development Order 2015 — Classes A-E for householders, plus commercial and agricultural classes.

When to use: Use before applying for planning permission. Many extensions, loft conversions, outbuildings, and changes don't need a planning application.

🔄

Change of Use New

Use Classes Order analysis — check if your change is permitted, needs prior approval (e.g. Class MA office-to-resi), or requires full planning permission.

When to use: Use when converting a building from one use to another: office to residential, shop to café, agricultural to dwelling, etc.
