Reduce Fall Through
A quarter of agreed sales never complete. Yours do not have to.
Most fall through is not bad luck. It is a stall nobody watched until it was too late. Reduce the rate and you keep commission you have already earned.

The Real Picture
It is fragility, not one dramatic break.
Agents talk about chains breaking, but in 2026 that is the rarest of the common causes. The deal dies because the buyer goes cold, a mortgage offer drifts to expiry, or a solicitor goes quiet for weeks. The loss is spread across the whole transaction, and almost none of it happens over price.
That matters, because you cannot reduce a rate you misread. If you watch only the chain you miss the buyer losing nerve and the offer running down the clock, which is where most of the damage is.
The Four Levers
What actually moves the rate.
Watch every party, every day
Solicitor, broker, surveyor, lender, on every live deal. The first sign of a stall is a missed response, not a missed completion. You can only act on it if you see it.
Act on the first signal, not the last
A nine day silence is recoverable. A lapsed offer is not. The agencies with the lowest fall through rate intervene early, while there is still room to fix it.
Keep the buyer committed
The biggest single cause is the buyer walking. Steady contact and quick answers keep nerve from turning into withdrawal.
Never let a mortgage offer drift
Offers are dated. A long transaction eats the calendar. Track the expiry and chase before it lapses, not after.
Why Manual Fails At Scale
No team can watch everything by memory.
Pulling all four levers by hand means tracking every party across every live deal, every day, for months. At Prime Central London volume and timelines that is impossible by memory and spreadsheet. Something always slips, and it is usually the deal that looked safe.
Alunio checks every deal every hour, day and night, flags the one that is drifting, and drafts the chase to the party holding it up. It pulls the levers for you, so a negotiator acts early instead of finding out late. Read more on why deals fall through.

What is a good fall through rate for an estate agency?
Across the United Kingdom around one in four agreed sales collapses before completion. A boutique that watches every party and acts on the first sign of a stall can keep its own rate well below that. The number you control is the share of slips you catch early enough to save.
What causes most sales to fall through in 2026?
The largest causes are the buyer withdrawing and mortgage problems, followed by slow conveyancing. Chains breaking are the smallest of the common causes. The pattern is delay and fragility across the whole transaction, not one dramatic snap.
How does Alunio reduce fall through rate?
It scores every live deal for risk each morning, surfaces the one most likely to slip, and drafts the chase to the party holding it up. You act on the first sign of a stall instead of the last, which is the single thing that moves the rate.
