Who uses planning data
Planning applications affect valuations, mortgage decisions, and buy/sell timing. Here's how teams embed them.
🏠 Estate agents & portals
Show nearby planning applications on listing pages, a legitimate differentiator vs major portals. Buyers want to know if there's a 200-flat development planned next door before they offer.
📋 Conveyancers & searches
Planning searches are a standard part of property due diligence. Replace manual council lookups with a single API call, returns the applications held near a property address.
🏗️ Developers & land agents
Screen sites by planning history before committing to feasibility. Identify approved applications for comparable schemes, and track pending decisions for competitor or adjacent sites in real time.
🏦 Valuers & mortgage lenders
Nearby approved developments can materially affect valuations. Flag applications within 100m of a subject property during automated valuation model (AVM) runs to surface cases that need surveyor review.
Practical patterns
Two common queries: finding pending applications in an area, and checking whether a specific address has recent planning history.
curl -G "https://api.homedata.co.uk/planning/search/" \ --data-urlencode "postcode=SW1A 2AA" \ --data-urlencode "radius_km=0.5" \ --data-urlencode "status=Undecided" \ --data-urlencode "type=Full" \ -H "Authorization: Api-Key YOUR_API_KEY"
Returns only Full planning applications that haven't been decided yet within 500m. Good for surfacing material planning risk to buyers.
curl -G "https://api.homedata.co.uk/planning/search/" \ --data-urlencode "postcode=EC1A 1BB" \ --data-urlencode "radius_km=1.0" \ --data-urlencode "days=365" \ --data-urlencode "type=Full" \ -H "Authorization: Api-Key YOUR_API_KEY"
Full applications within 1km over the last year: use for site appraisals, comparable scheme searches, and development feasibility screening.
