Monitor

Know the moment an area moves.

Save the areas you care about and we keep watch. When something real shifts, prices jump, crime climbs, a rating changes, you hear about it straight away. Only the moves that matter, so you are never buried in noise.

Only the moves that matter.

We watch the numbers month to month, hold back the noise, and only tell you when something genuinely changed, in a form your systems can trust.

The noise stays out

We compare each area to the month before and only surface the moves big enough to act on. A 47% jump built on two sales never reaches you.

See exactly what shifted

Every change shows the value before, the value after and the periods compared. No guessing what moved.

Signed, so you know it is real

Each alert is signed, so your systems can check it genuinely came from us before acting on it.

You set what counts

Decide what a real move means for you, and we hold everything else back.

Keep a whole book under watch

Alerts land where you already work

Changes arrive as a message straight to your own systems, your app, your Slack, your inbox, the moment they happen. Nothing new to check.

Frequently asked

Monitor, answered.

What can you watch?

Any UK areas you save into a book: prices, crime, school ratings and the rest. Save a handful or a few hundred at once.

How do you decide what counts as a real change?

You set the rules: compare to last month or a year ago, ignore anything smaller than a percentage you choose, and skip moves built on too few sales.

Why will a big jump not always alert me?

If a move is based on only a handful of transactions it is not reliable, so we hold it back until there is enough behind it to trust.

How do alerts reach me?

As a message straight to your own systems, your webhook, Slack, email or app, the moment a change happens.

How do I know an alert is genuine?

Every alert is signed, so your systems can check it really came from us before acting on it.

How often does it check?

On a schedule you set, or on demand whenever you want a fresh read.

How do I get started?

Save a book of areas and switch on alerts, or book a call and we will set it up on your own portfolio.

Never miss a move that matters.

Put your areas under watch and get a trustworthy heads-up the moment something real changes. Only the moves worth your attention.
