1. Hiring an in-house UK SDR
A permanent hire gives you the most control and the closest cultural fit — but the advertised salary is only part of the story. A UK sales development rep commonly commands a base of £30,000 to £45,000. On top of that sit employer National Insurance, auto-enrolment pension, holiday and sick cover, tooling and software licences, a desk, and the management time it takes to lead them. Add a recruitment fee to land the person in the first place, plus the very real risk that an early hire doesn't work out.
Once you total the hidden costs, a single SDR realistically lands north of £50,000 in year one. That's before you've factored in the weeks of ramp-up before they're productive. It's a sound choice if you have the volume and management bandwidth to justify it — but it's a bigger commitment than the headline salary suggests.
