How to negotiate a Full Stack Developer offer in London
The difference between the 25th and 75th percentile is £43K/year — and it comes down to this conversation.
Anchor above the median
Open at £164K — the 75th percentile. This gives you room to "meet in the middle" at or above the median. Never give a range; ranges get taken at the low end.
Use competing offers as leverage
A competing offer — even from a less preferred employer — is the single most powerful negotiating tool in London. Get at least one before negotiating.
Negotiate total comp, not just base
Base salary is often the hardest component to move. Signing bonus and equity are frequently more flexible. In London, a £14K signing bonus has the same year-1 value.
Never accept on the call
Ask for the offer in writing and follow up in 24–48 hours. This creates space to counter without pressure. No legitimate employer rescinds an offer because a candidate asked for review time.
