A stunning and deceptively spacious1 family home in one of the area's most sought-after locations.

Just a stone's throw2 from the station and within the catchment3 for outstanding schools. Beautifully presented throughout and offered chain free4, with huge potential to extend5 to the rear STPP.

This is truly the perfect family home6 and it won't last7 long. Must be seen to be appreciated8 — early viewing essential!

The guidance was withdrawn. The liability wasn't.

Since May 2025 there has been no sector-specific checklist for what a listing must disclose — only a law that fines agents for getting it wrong. That gap is why this exists.

One of these is on the market this morning. Its particulars are already written.


The careful one fails too

This one is priced, tenured, banded and EPC-rated. Nothing about it looks careless — and it still fails, because the fields portals now hard-gate are the ones nobody writes.

Scope of the audit

The audit is rule-based, not generative. The same listing always produces the same findings, each pointing at the text that triggered it and the duty it engages — which is what makes a report you can rely on months later, and what makes it free to run.

What is missing. Every disclosure the withdrawn guidance expected and portals still gate on — tenure, charges, construction, services, connectivity — with conditionals applied intelligently: leasehold costs only where tenure is leasehold, cladding and EWS1 only where the property is a flat.

Parts A–C

What is asserted without support. Chain-free claims, catchment promises, development potential, floor areas, yields. Each is lawful when the file evidences it; the audit asks whether it does.

DMCC s.226

What is unlawful outright. Benefit-status exclusions and restrictions framed around family, age or sex — flagged as critical, because no file note makes them acceptable.

Equality Act 2010

What you can prove later. Every audit is dated and fingerprinted to the exact text it read. When a complaint lands months on, the record of what you checked already exists.
