You hand in your resignation on a Tuesday morning, braced for an awkward five-minute conversation. By Thursday, HR wants a call, and your manager is suddenly talking about a pay rise that didn't exist the week before. Nothing about your role has changed. What's changed is that you're now, for the first time in years, worth negotiating with.
This is the counteroffer moment, and it catches most people off guard precisely because it arrives dressed as good news. A number appears — often somewhere between 8% and 15% above your current salary, occasionally more if you're senior enough that replacing you would be genuinely painful — and it lands at the exact moment your resolve is weakest. You've already done the hard emotional work of deciding to leave. Now someone is offering you a way to keep the extra money without doing any of the difficult bits, like updating your CV again or explaining a short tenure at your next job. It feels like a win. Recruiters who've watched this play out for years will tell you it rarely is.
Why the money appears the moment you resign
UK employers counter because replacing you is expensive, and not in a vague, abstract sense — in a specific, budgeted one. Contingency recruiter fees typically run 15–20% of a role's first-year salary, and that's before you count the weeks of a job spent unfilled, the onboarding time for whoever replaces you, and the six-to-nine months it usually takes a new hire to reach your current level of output. For a £45,000 role, that arithmetic alone can justify finding an extra £4,000 or £5,000 a year to keep you at your desk. Your manager isn't necessarily being generous. They're often just doing the maths that HR did for them. Add a departing senior employee's client relationships and unwritten institutional knowledge to that same ledger, and the number looks even more justified from where finance is sitting.
Some employers get around raising your base salary by offering a one-off retention bonus instead, often split into two payments six months apart, timed deliberately to cover the exact window when a newly counteroffered employee is most likely to start looking again. It's worth asking directly whether the figure on the table is base pay or a bonus, because the two behave very differently at your next pay review, on a mortgage application, and on your pension statement. A £4,000 bonus vanishes from your annual salary the moment it's paid; a £4,000 base rise compounds every year after.
There's also a timing problem baked into how most counteroffers happen. Few line managers can approve a pay rise on the spot — the number usually has to clear a budget conversation with finance, sometimes a sign-off from someone two levels up who has never met you. That's why the counteroffer conversation often doesn't land the same day you resign; expect anywhere from 24 hours to most of a week while someone works out what they're allowed to offer. If the silence stretches past your notice period's midpoint, take that as information in itself — a company that valued you enough to counter would usually move faster than that.
The real reason to be wary of saying yes
The counteroffer isn't really for you.
It's for the six to twelve months it will take to find, hire and train your replacement without the disruption happening on anyone's watch this quarter. Recruitment consultancies that track this consistently report the same pattern: a majority of people who accept a counteroffer are job-hunting again within a year, often because the thing that pushed them to resign in the first place — a manager they'd stopped trusting, a role that had quietly outgrown its job title, a ceiling they could see three years out — was never actually about the payslip. Money is the easiest problem for a company to solve because it doesn't require anyone to admit they mismanaged you, promoted the wrong person over you, or let your workload creep for two years without a conversation.
This works reasonably well if pay genuinely was the entire issue — you'd been underpaid relative to the market, you said so, nobody listened until you had another offer in hand, and now the number matches what you're worth. In that specific case, taking the counteroffer isn't naive; it's just a slower, more awkward route to a fair salary. It falls apart the moment the real reason was your manager, or the two-hour commute, or watching someone with less experience get promoted past you last spring, because a percentage increase touches none of those things. You'll be earning more to sit inside the exact same problem. Ask yourself honestly which version of the story is true before the new number has a chance to blur your memory of why you started looking. Six months from now, once the relief of a bigger payslip has faded, the same manager and the same commute will still be sitting exactly where you left them.
What a counteroffer is actually buying you
The salary number on its own
Compare it properly. If the outside offer was £52,000 and your counteroffer lands at £49,000, you haven't been offered a raise — you've been offered a discount on staying somewhere you'd already decided to leave. Work out the number against the market rate for your role, not against what you currently earn; a 10% bump on an already-below-market salary can still leave you underpaid.
What the number is worth after tax
A £5,000 increase looks generous as a headline figure but shrinks fast once tax, National Insurance and pension contributions take their share. If part of the rise pushes you into the higher-rate tax band, roughly four pounds in every extra ten goes straight to HMRC rather than your current account, and auto-enrolment pension contributions usually take another slice before you see anything at all. Ask payroll for the actual monthly take-home difference in writing rather than doing the sums yourself at the negotiating table; a business genuinely trying to keep you can usually turn that figure around within a day, and won't mind being asked.
The role, quietly rewritten
Ask directly what changes beyond the number. Does the counteroffer include a new title, a different reporting line, a clear promotion timeline in writing? Or is it the same job, same manager, same ceiling, with more money attached to keep you quiet about it for another eighteen months? A counteroffer that only moves the salary field and nothing else is usually a stalling tactic dressed as a resolution.
Trust, once it's been tested
Here's the uncomfortable part almost nobody says out loud: once you've resigned, you're marked. Redundancy conversations, the next round of promotions, the stretch project everyone wants — you'll quietly stop being first in line for any of it, because you've shown you'll leave given the right offer. That's not vindictive on your employer's part. It's just how organisations manage risk, and it's precisely why UK recruitment specialists so often advise against counteroffers even when the money is genuinely competitive.
A decision framework that actually holds up
Before you respond to a counteroffer, sit down with the answers to these, in writing if you can manage it. A five-minute list on your phone is enough — the point is forcing yourself past the initial flattery of being asked to stay.
- Write down the single real reason you started looking in the first place — not the polite reason you gave HR, the actual one.
- Check whether the counteroffer addresses that reason directly, or only the salary line.
- Compare the offer against market rate for your role and region, not against your current pay.
- Ask what's written down versus what's promised verbally — titles, reporting lines and promotion timelines mean far more in an email than in a corridor conversation.
- Consider your notice period. Statutory minimum under the Employment Rights Act 1996 is one week per completed year of service up to 12 weeks, but most contracts specify one to three months regardless — check what you've actually signed before assuming you have room to change your mind twice.
If the honest answer to the first two points is "yes, this fixes the actual problem," take the counteroffer and don't feel embarrassed about it — staying isn't a failure of nerve. If the answer is "this only fixes the number," walk. That second scenario is far more common than people admit, and no salary line has ever fixed a bad manager.
Negotiating without burning the exit you already have
If you do decide to leave, resist the urge to use the counteroffer as leverage against the new employer, and resist the opposite urge to burn bridges with your current one out of relief at finally saying it out loud. Hand in your notice cleanly, work your notice period properly even if it stings, and keep the counteroffer conversation businesslike rather than emotional — you may well cross paths with these people again, whether as a client, a reference, or a future colleague at a third company neither of you has joined yet.
And if you genuinely are tempted to stay, say so plainly rather than negotiating from both sides at once. HR teams talk to each other more than people expect, and a candidate who strings out a start date while quietly renegotiating with their current employer tends to be remembered for exactly that, long after the counteroffer itself has been forgotten.
A short, direct line to your new employer does more good than a vague delay ever will: "I've been offered more to stay, and I want to be straightforward with you rather than go quiet — I'm still planning to join, but I wanted you to know that conversation happened." Most hiring managers respect that far more than silence, because it tells them exactly what kind of colleague you'll be the next time something awkward needs saying out loud rather than avoided.
