Planning Application Checklist
Everything you need to know before and during a planning application — from checking whether you need permission through to what to do when it is approved.
Before You Start
Confirm whether your project requires planning permission or falls under Permitted Development
Check if your property is in a Conservation Area, AONB, or National Park — restrictions apply
Check if your property is Listed — Listed Building Consent required for most works
Check if an Article 4 Direction removes Permitted Development rights in your area
Speak to your local planning authority's pre-application advice service (chargeable but valuable)
Documents You Need
Location plan (Ordnance Survey at 1:1250 or 1:2500) showing the site and surrounding area
Site plan (1:500) showing the site boundaries and proposed works
Existing floor plans and elevations (architect-drawn)
Proposed floor plans and elevations showing all changes
Design and Access Statement (required for some applications)
Heritage Statement (if in a Conservation Area or near Listed Buildings)
During the Application
Submit via the Planning Portal (www.planningportal.co.uk) or your local authority website
Pay the planning fee (currently £258 for most householder applications in England — check current fee)
Note the 8-week statutory determination period (13 weeks for major applications)
Respond promptly to any requests for additional information from the planning officer
Monitor the application on the local authority's public website
If Approved
Check all planning conditions — some must be discharged before works begin
Note the expiry date — planning permission typically lasts 3 years
Apply for discharge of pre-commencement conditions before starting
Keep a copy of the decision notice and approved drawings on site
Notify Building Control before starting — planning approval ≠ building regulations approval
