How do I respond to a low-ball job offer in the UK?

Don't accept on the spot. Even if the offer is acceptable, take 24-48 hours to consider. Accepting immediately signals you'd have accepted less.

Counter with market data. 'Based on my research into similar roles in [sector] in [city], I was expecting closer to £X. Could we discuss adjusting to that level?' Specific market reference makes the counter defensible.

Counter with multiple components. Base salary is the main one but bonus, pension match, equity, holiday, sign-on bonus, and start date all negotiate. Consider what trade-offs work for you.

If the company refuses entirely, evaluate the underlying number. UK roles offered at 15%+ below market often signal cultural problems — companies that pay below market typically have other compromises too.

Don't bluff. If you say you have a competing offer, have one. UK recruiters call bluffs and the candidate loses leverage when caught.

Set your floor before negotiating. The minimum acceptable salary, expressed in advance, prevents emotional decisions. If they go below the floor, decline professionally.
