Making property processes simple.
BILTD helps homeowners navigate planning permission, building regulations, and every process in between. We turn complex rules into clear, actionable guidance.
Homeowners deserve better tools.
Planning permission in England is complicated. The rules are buried in legislation, the guidance is written for professionals, and getting basic answers often means paying for a consultant before you even know if your project is viable.
We started BILTD because we believe homeowners should be able to understand the rules that apply to their own property, without needing a planning degree or a large upfront budget.
Every tool and report we build takes authoritative government data and translates it into plain English, tailored to your specific address and project. Whether you’re checking if your extension is permitted development or preparing an LDC application, we make the process straightforward.
Authoritative sources you can trust.
Every assessment and report is generated from official government data sources, verified and current at the time of generation.
