Submitting a planning application can feel intimidating if you've never done it before, but the process itself is fairly linear once you know what's involved. Here's the step-by-step version.
Step 1: Establish whether you need to apply
Before anything else, confirm whether your project actually needs a full planning application or whether it's covered by permitted development. This single question changes the whole process, so it's worth getting a clear answer before you commission any drawings.
Step 2: Get your drawings prepared
Every planning application needs a set of drawings showing the existing property and the proposed changes — typically location and site plans, existing and proposed elevations, and floor plans. These need to be accurate and to a standard your local council can properly assess; hand-drawn sketches or rough measurements are a common reason applications get delayed or rejected outright.
Step 3: Gather your supporting documents
Depending on your project and your council, you may also need additional documents — things like a design and access statement, a site location plan referenced to Ordnance Survey data, or specific reports if your property is in a flood zone, conservation area, or near a listed building. Your local council's planning portal will list exactly what's required for your specific application type.
Step 4: Submit through the Planning Portal
Most UK planning applications are submitted online via the national Planning Portal, which routes your application and documents to your local planning authority along with the relevant fee. You'll receive an application reference number and a validation check — if anything is missing, the council will come back to you before formally registering the application.
Step 5: The decision period
Once validated, your local authority has a statutory period (commonly eight weeks for most householder applications, though this can vary) to make a decision. During this time, neighbours may be consulted and a case officer may visit the site. You'll be notified of the outcome — approval, approval with conditions, or refusal — in writing.
Why professional drawings improve your chances
Clear, accurate, professionally prepared drawings reduce the number of queries a case officer needs to raise and give your application the best possible chance of moving through without delay. A poorly presented application is far more likely to trigger requests for further information — which resets the clock on your decision.
