    The Real Cost of a UK SDR in 2026

    The hidden costs

    What no one puts in the budget line

    These are the costs that don't show up on the offer letter — but they're real, recurring and they're why the headline salary is so misleading.

    Ramp time

    A new SDR takes 3–4 months to be net-productive. That's £15k+ of dead cost before the first booked meeting.

    Burnout & churn

    UK SDR roles have ~50% annual churn. Every leaver resets the clock and costs £6–10k in lost pipeline + recruitment.

    Data quality drag

    SDRs spend 30–40% of their time enriching, deduping and updating CRM records. Pure non-revenue work.

    Tooling sprawl

    LinkedIn Sales Navigator + Apollo + Outreach + Gong + dialler = £250–£400/seat/month before salary.
