Run on official data, built with chartered surveyor input
Every homeowner with a renovation in mind asks the same first three questions — can I build it, what will it cost, and is it worth it? Answering them properly used to take a consultant's afternoon. The data has been public for years; it was just scattered across a dozen government systems that don't talk to each other.
Planning Permission Checker connects them. It resolves an address, checks it against official planning constraint boundaries, pulls the real sold prices around it, and puts honest cost ranges next to the result — every figure cited, every limit stated. It is the pre-feasibility check to run before you spend money on advice.
The expert layer
Planning is a regulated field, so the methodology here is built with input from a RICS-regulated chartered surveyor: Savas Bulduk MRICS, Director of Hampstead Chartered Surveyors & Building Consultancy (RICS Firm Reg. 923064). The deterministic engine establishes the facts from official data, and the published guidance is reviewed for accuracy. Per-address reports are system-generated using this surveyor-led methodology and are not individually reviewed unless you request the Surveyor-Reviewed Pack, which is individually reviewed by Hampstead Chartered Surveyors. Where a project needs real professional input — listed building consent, a licence to alter, party wall matters, or a feasibility review — we point you to Hampstead Chartered Surveyors to enquire directly about paid advice. Some projects may also need drawings, planning consultancy, structural engineering, legal advice or other specialist input.
How the commercial model works, plainly
Planning Permission Checker is free to use and does not sell your data. The model is the handoff: with your consent, a serious enquiry is routed to paid professional advice off the site. That is deliberate — the portal's only job is to be accurate and neutral, because trust is what generates good enquiries. The methodology page documents exactly what every number is built on.
What Planning Permission Checker is not
It is not planning advice — it is intelligence for the moment before you pay for advice. Planning outcomes belong to local authorities; estimates here are ranges to be verified by qualified professionals. The site tells you when confidence is low rather than dressing it up. That honesty is the product.
