sleuth.house CASE FILES FOR UK HOUSE HUNTERS

A buyer's copilot for the UK house hunt

Every house has a case file.

The listing is the estate agent's story. Sleuth reads the public record while you browse — the real plot size, what the EPC would cost to fix, how long it's really been on the market — and keeps one shortlist you and your partner rank together.

Free capture extension first, Pro enrichments after. One email when it opens — nothing else.

What the listing won't tell you

Sleuth cross-examines every property you save against open government data — the same records surveyors and buying agents pull, fetched in seconds instead of billed by the hour.

EXHIBIT A — LAND

The actual plot, measured

"Generous garden" is a vibe. Sleuth finds the property's Land Registry parcel and measures it — plot, footprint, and what's actually left outside.

plot 412 m² · footprint 96 m²
outdoor 316 m² confirmed

EXHIBIT B — ENERGY

The EPC, costed

Every EPC lists upgrade measures. Sleuth reads the official certificate and totals the ones that pay their way — so a "D" stops being a mystery and becomes a number.

58 D today → 74 C
for ≈ £1,850 of sensible work

EXHIBIT C — TIME

True days on market

Delist, wait, relist: the "new" badge resets, the history doesn't. Sleuth links relistings and keeps the price journey, so you know who's really under pressure.

No crawlers. Just your browsing, upgraded.

Sleuth is a browser extension. It only ever reads the listings you open yourself — then does the detective work.

Browse as normal

Rightmove searches, evening scrolling, the usual. Nothing to import, no new habits.

Capture what you like

One click saves the listings on the page into your own shortlist — yours, stored locally, exportable.

Sleuth pulls the file

Plot, EPC economics, market history, commute times to the places you actually go. Estimates are always marked ≈.

A house needs two yeses.

Buying with someone? You each rank every house one to five stars, with your reasons. One shared board, no forwarded links, no "wait, which one was that?" — and a one-star from either of you files the case away, with the dealbreaker on record.

Sleuth started as a tracker built by one couple to find their own home on the Kent coast. It ran every night for months, read a few thousand listings, and found the house. This is that engine, packaged.
