UK Pay Rise · Recruiter Guide
How to Ask for a Pay Rise When You Discover You're Underpaid
When this conversation works
Most successful when you have hard market data — recent recruiter outreach with specific bands, multiple Glassdoor data points, or a peer's confirmed salary. UK employers will usually correct meaningful under-payment when presented with clear evidence. The strongest position is having an external offer in hand; the second-strongest is documented market data showing the gap.
When to wait
If you've been at the company a long time (5+ years) and haven't pushed pay reviews, the gap is often material and harder to close in one conversation. Companies prefer to spread the correction across 2-3 cycles. If the company's overall pay structure has fallen behind market (rather than just yours), individual fixes are harder.
Recruiter-tested script
"I wanted to raise something I've been thinking about. Based on recent market research — including [specific data: recruiter outreach, Glassdoor, peer conversations] — the market rate for [role + level] in [sector] in [city] is around £[X]. My current pay is £[Y], which puts me [Z%] below the market median. I've been performing at this level for [timeframe] and I'd like to discuss closing the gap. Could we look at adjusting to £[X], either in one step or over the next [timeframe]?"
Adapt the variables [X], [Y], [specific outcomes] to your situation. Practise out loud before the call.
Preparation steps
- 1 Gather 3 sources of market data: recruiter outreach, Glassdoor/LinkedIn, peer information
- 2 Calculate the specific gap as a percentage and as a £ figure
- 3 Decide your minimum acceptable adjustment (the company will usually counter)
- 4 Have a backup plan — interviewing externally — in case the ask fails
- 5 Choose timing: outside review cycles is sometimes better for off-cycle adjustments
Common mistakes
- ✗No specific market data — flags emotional rather than commercial argument
- ✗Asking for the full gap immediately — usually unrealistic; phased adjustment is more achievable
- ✗Threatening to leave without actually being prepared to leave
- ✗Citing one data point (Glassdoor only) — flags shallow research
- ✗Framing as 'fairness' rather than 'market alignment' — emotional triggers defensiveness
Recruiter pro tip
The most effective backup for under-pay conversations is having an external offer in hand — even if you don't want to leave. UK employers respond materially differently to 'I think I'm underpaid' versus 'I have an offer at £X and would prefer to stay'. The difference is 5-15% on average. The candidates who don't have a backup offer often accept smaller adjustments than they would otherwise; the offer creates leverage even if you don't use it.
Realistic outcome
Realistic outcome: 5-15% adjustment in one step at most UK employers; 15-25% if you have an external offer to anchor. Phased adjustments (split across 2-3 cycles) are common at larger employers with rigid structures. Full-gap fixes typically require external moves rather than internal corrections.
