What is a planning constraints report?
A report that establishes, for one specific property, which planning constraints actually apply — conservation-area status, Article 4 directions, listed-building risk — plus the realistic planning route for the work you have in mind, indicative build-cost ranges and the next steps. Ours checks the property's own coordinates against official planning.data.gov.uk geometry rather than summarising borough-level generalities.
What's in the £59 Property Works Feasibility Report?
A planning-route summary for your intended work, conservation-area and Article 4 state checked at the property's coordinates, listed-building and leasehold prompts, party-wall and neighbour-risk prompts, build-cost ranges (always low/typical/high, never a single price) and suggested next steps — in a printable report you can share with your architect or surveyor. It is generated instantly by our system.
Is the £59 report reviewed by a surveyor?
No — the £59 report is system-generated and is not individually reviewed by a chartered surveyor. If you want professional eyes on it, the £295 Surveyor-Reviewed Feasibility Pack is the same report individually reviewed by a chartered surveyor at Hampstead Chartered Surveyors (RICS-regulated, Firm Reg. 923064), with comments on your specific risks and nearby planning decisions looked up on the council register.
How is this different from a £10 AI planning report?
Two ways. First, the constraint answers aren't generated by a language model — they come from checking your property's coordinates against the official constraint geometry, and anything we can't check is stated as not checked rather than guessed. Second, we deliberately don't sell an "approval likelihood score": no algorithm can honestly score a London planning decision, so every figure in our reports is cited and confidence-labelled instead. And when you want a professional judgement, the £295 and £495 tiers are fulfilled by an RICS-regulated chartered surveyor practice — not a bigger prompt.
Can I use this before buying a house?
Yes — a pre-purchase check is one of the most common uses. Before you commit, the report shows whether the extension or loft you're planning is realistic at that address: the conservation-area and Article 4 state, the planning route, and the cost ranges. For a purchase decision, the surveyor-reviewed tiers add a chartered surveyor's comments on what to investigate before exchange.
How quickly do I get it?
The £59 report is generated and delivered instantly after checkout. The £295 and £495 surveyor-reviewed packs are prepared manually by Hampstead Chartered Surveyors and emailed within 2 working days; the £495 tier's 30-minute consultation call is arranged after the pack is sent.
Is this planning advice or a planning decision?
Neither. Every tier is an early-stage feasibility view built from official data — not a planning decision, not a valuation, and not a substitute for the council's own pre-application advice where your project needs it. The reports exist so you spend money with professionals in the right order, armed with the actual constraint state of your property.
Planning Permission Checker provides planning and cost intelligence for early feasibility only. It is not legal, planning, valuation, architectural, structural, or surveying advice. All estimates are indicative and must be verified by qualified professionals before purchase, design, planning submission, or construction.
Cost estimates are indicative only — not a quotation. Final price depends on survey, specification, structure, access, party wall matters, VAT, professional fees, and contractor availability.
Planning outcomes are not guaranteed. Local planning authorities make final decisions.
