How do I respond when asked my current salary?

Why it matters. UK candidates who disclose current salary typically get offers at current + 5-15%. Candidates who refuse to disclose and anchor to market rate typically get offers in the upper third of the band. The difference compounds over your career.

First-line response. 'I'd rather focus on the market rate for this specific role rather than my current salary. Based on similar roles I've researched, I'd be looking at around £X.' This is professional, redirects the conversation, and asserts your value confidently.

If they push. 'My current salary reflects a different role with different scope. The market rate for this position is what's relevant.' Then immediately propose a number for this role.

If they push hard. 'I'm currently on £Y, but I'm looking at the market rate for this role which is £X.' Disclose the number but re-anchor immediately. Don't let your current salary become the starting point of the negotiation.

When you have to disclose (rare). Some application forms force a number. Use 'targeted' or 'desired' framing if the form allows. If it requires 'current', enter your current and be prepared to defend the gap to your target during the conversation.
