FlatSignal watches the market and turns the daily flood of listing alerts into one ranked, de-duplicated view: the genuinely new places, scored on what makes a good let, and grouped by area — so you spend your time viewing, not sifting.
What it is
Instead of ten browser tabs and a dozen repeat alerts, FlatSignal gives you a single dashboard of every new listing that matches your search — each one normalised into the same shape, de-duplicated across portals, scored, and filed under its London area. It's built for the way renting actually works: fast, competitive, and unforgiving of a slow inbox.
The same flat listed on three portals collapses into one entry — no more déjà vu scrolling.
A 0–100 score for each listing — value, location, freshness, completeness — and the reasoning behind it, never a black box.
Grouped into 110+ London areas with zones and stations, so you browse where you actually want to live.
New listings are flagged the moment they appear, and refreshed automatically through the day.
Why it exists
Good flats go in hours, not days — but the portals bury the new ones under sponsored tiles, stale re-lists and the same property posted four times by four agents. By the time you've waded through it, the place you wanted is gone. FlatSignal exists to remove that friction: one honest, ranked feed of what's actually new, so you can move first. It does the sifting; you make the call.
How it works
Your saved searches on Rightmove, Zoopla, OnTheMarket and OpenRent send their alerts to one dedicated inbox.
FlatSignal parses each alert into a common shape and folds duplicate listings of the same property together.
Every listing gets a transparent 0–100 score and is filed under its London area, newest and best first.
Skim the ranked dashboard, open the ones you like straight on the portal, and enquire before the crowd.
Built to be honest
FlatSignal reads listing-alert emails you asked for — it doesn't scrape the portals, invent detail, or hide how it works. It's a discovery and shortlisting tool: it points you at the listing on its original source, and leaves the enquiry to you.
