Great site. This data should really be more accessible. Planning in the UK is a total crapshoot, subject to the whims of the planning authorities. In our case, a simple rear extension and dormer loft conversion, similar to hundreds of thousands across the country, we ended up having to appeal which added 2 years and tens of thousands of pounds in costs to our extension project. Our area shows up as a high refusal area, which tracks.

It would be good to add appeal data in (also a public gateway) to show which councils are just being unreasonable.

I personally think the planning regulations in this country are the cause of many ills, including the housing shortage. It just costs so much to get through planning these days, it is often just not worth it. Data like this could help us get that changed.

Really useful feedback, cheers. Yeah, "Mixed results" is kinda rubbish as you say. It should give you something concrete before asking for anything. I'll fix that today. Fair point on the £79 upsell at the end of a £19 report too. That's tone deaf and I'll move it. On the £19... I'll think about it, but you're right the site needs to do more to justify the spend before pulling out a card. Appreciate the honest take!

Just a quick follow up, if my reply seemed very harsh, view that as a sign of how enthusiastic I was to see the website at first. I understand wanting to make money, but I'd seriously consider giving a lot more away (maybe even the basic report stuff) away for free, I'd love to explore my local area, my parent's, be nosey what life is like in Oxford (a place I previously lived), but even if I was willing to pay (I'm…

No, that's absolutely a fair follow-up and not harsh at all. It's very helpful. The "be nosey about places you used to live" use case is exactly what the postcode tool should serve (thinking about it), and right now it doesn't. You're right that PDF-downloads break flow badly. Tbh... that's a hangover from the "people want a thing they can save" assumption that I'm still stuck in, I guess. I'm still on the fence about giving the paid reports away wholesale, but the gap between "tells you nothing" and "£19 PDF" is way too big. I'm gonna need a middle layer of free but actually useful exploration on the site. Will have a solid think about this today. Appreciate the feedback!

Working on similar problem in another domain. I found agentic direction powerful with browser use plugged into a multimodal (strong agentic capability) llm like gpt 5.4 mini working in a loop with orchestrator evaluator/judge.

Nice! Yeah, I went the other way... deterministic scrapers per portal type because once you've worked out the search form quirks for an Idox or Northgate or Ocellaweb, it's the same shape across every council using that platform. So the marginal cost of adding council N is config not code. The agentic approach gets more interesting for the long tail though — the bespoke ASP.NET ones where every council is its own sno…

Deterministic scrapers are almost certainly the right answer for this task, because once those special snowflakes have paid for their bespoke IT system, they'll never change it.

On the grind, why not get an agent to help you build the long tail of deterministic scrapers? Claude etc is really shockingly good at this kind of moderate-complexity iterative work, it will just keep going around the fetch/parse/understand loop until it has what you're looking for.

I'm also enthusiastic, it's not often you see people find a genuinely underserved niche and you have.

I don't know if I would pay £19 for a general state-of-the-area report. I would almost certainly have paid £100-300 for a service that took my planning application, critically reviewed it and told me which aspects were and were not likely to pass, with references to specific examples within my local area.

Maybe a tongue-in-cheek comment but regulations are that way because you guys want it that way (maybe not you personally). If it wasn't like that, nothing would stop a garbage incinerator or a quarry popping up a few hundred meters from houses (which happens in European countries with more deregulated planning/zoning regulations).

You guys have all kinds of pro-individualistic, borderline nonsensical residental housing laws like "right to light" and "right to view". It's completely incompatible with "build more". Most British people view their privacy (or perceived privacy) as a higher priority than fixing the housing market. "It's so overlooked" is such common comment and it's almost bizarre to someone used to living in a higher density environment (like the UK very much is).

Have you tried using Browserless/similar to scrape around tricky hosts?

No, I haven't tried Browserless. So far, it has all been from a single residential IP which is probably the bigger issue with Liverpool than the WAF challenge itself. Once I have a valid session cookie I can solve the JS challenge fine, the rate limit is per-IP. Rotating residential proxies (or Browserless behind one) might be the answer... I'm just reluctant at this stage to bite the bullet on the cost for a single (albeit huge) council. Have you used it for similar stuff?
