Assignment fee calculator
What your fee actually is once the seller negotiates — and the point at which there is nothing left in the deal for you.
Every pound the seller does not take comes back to your fee, and every pound you concede on the offer goes the other way. At your maximum the fee is £5,067. Know these three numbers before the call, or you will negotiate away your own fee without noticing.

This is one sum out of a whole deal
Inside the app the same engines run against real HM Land Registry sold prices, rank your buyers against the deal, and tell you what to do next — with the workings attached to every figure, exactly as they are here.
The demo runs on invented deals and real postcodes. No account, nothing saved.
Questions
Why does my fee go up when the seller takes less?
Because the end buyer's ceiling does not move. The gap between what the buyer can pay and what the seller accepts is the fee, so anything you negotiate off the purchase price lands in your side of it.
What is a normal UK assignment fee?
There is no standard, and anyone quoting one is guessing. What matters is your own floor — the number below which the work is not worth doing — and this tool exists to show you when a deal has crossed it.
