How do I negotiate a signing bonus in a UK job offer?
Why this matters
Most candidates don't think about signing bonuses until base negotiation stalls. But they're often easier to win than base because they're a one-off cost the company can budget separately. They're particularly useful when leaving a current role mid-bonus-cycle (you've earned but won't receive £X) — most UK employers will match the forfeited amount.
Step-by-step playbook
1) Calculate your forfeited compensation at current employer: pro-rata bonus, accrued unvested equity, performance pay you'd otherwise receive. 2) When negotiating offer, mention this directly: 'I'd be leaving £X in unvested compensation if I move now.' 3) If base is fixed, explicitly request a signing bonus to compensate. Suggest a specific number. 4) Ask for clear terms: amount, when paid (most are paid with first salary), claw-back conditions if you leave within 12-24 months. 5) Get the signing bonus in writing as part of the offer letter — never accept verbal-only. 6) If used as bridge to higher base: ensure the structure works for you (signing bonus paid 100% upfront is better than base paid in 12 monthly chunks). 7) Be aware of tax: signing bonuses are taxed as income via PAYE in the month received.
Word-for-word script / template
Email template: 'Hi [Name], Thank you for the offer. I'm enthusiastic about joining and want to find a way to make this work. The gap to my target is £[X] on base. I appreciate the band may be tight. Would you consider a signing bonus to bridge the gap? I'd also note that moving now means I'll forfeit £[Y] in pro-rata bonus / unvested equity at my current employer — a signing bonus equivalent to that figure would help offset the move. Would a £[Z] signing bonus, paid with the first month's salary, be possible? Thank you, [Your name]'
What NOT to do
Don't: ask for signing bonus and base lift simultaneously without prioritising; accept a signing bonus with hidden claw-back terms; accept it verbally only; assume it's tax-free (it isn't); use it to dress up a deeply underwhelming offer; demand it for personal reasons unrelated to the move.
Worked example
Olivia was offered £75k for a senior role; her current employer's annual bonus would pay £8k in March and she'd be leaving in November. She negotiated the offer up to £77k base + £8k signing bonus payable with month-1 salary. The signing bonus exactly compensated her forfeited bonus, making the move financially neutral on year-one comp + lifting her base trajectory by £4k vs original offer.
Recruiter pro tip
The phrase that wins signing bonuses: 'I'd be forfeiting £X in [bonus/equity/performance pay] by moving now.' This reframes the bonus from 'extra money' (which feels greedy) to 'compensation for a real loss' (which feels reasonable). HR has discretion on signing bonuses that they don't have on base. Use this asymmetry.
