How it works

Where the number comes from

We aggregate listings daily

Every London property listed across major portals is ingested, deduplicated, and stored — including any price changes over time.

We calculate a fair price

For listings with a floor area, we combine nearby Land Registry sold prices per m², apply the UK House Price Index, and multiply by the property's size.

You see the verdict instantly

Every valued listing shows the delta in plain English — below, about right, or above fair value — so you know before you book a viewing.

The verdict

Four states, one honest signal

The verdict only appears when a listing publishes its floor area — giving us enough data to calculate a credible fair price. We never guess.

We value roughly 30,000 of 80,000 London listings. The rest are browsable but unlabelled. We treat missing floor area as information, not an inconvenience — and we say so plainly.

Below fair value

Asking price is meaningfully below our fair price. The gap is shown in pounds — a good buy signal worth investigating.

Priced about right

Asking price is within a normal margin of fair value. Neutral — not amber. An accurately priced home shouldn't look like a warning.

Above fair value

Asking price exceeds our fair price estimate. Caution, not alarm — worth negotiating or comparing alternatives.

Not valued

No floor area was published by this listing. We won't guess. The property is still browsable — just without a verdict. Honesty as a feature.
