In-House SDR vs Outsourced Outbound: The Real Cost

I’ve been the “bad hire”. More than once. But it wasn’t always my fault.

I’ve been the new sales hire four or five times, and I can tell you exactly when it was on me and when it wasn’t.

When everything was in place (clear expectations, proper onboarding, a leader who had time to coach), I delivered. When it wasn’t, I struggled. Same person, different outcomes.

So when a founder asks me whether to hire an in-house SDR or buy outsourced outbound, I start with whether the business is ready for a hire. Then I look at what each option costs in year one, and how much of the work you’ll be able to see.

What does an in-house SDR cost in the UK?

One in-house SDR costs about £55,000 to £60,000 in year one, or £4,600 to £5,000 a month. The base salary on the advert is only about half of it.

Glassdoor UK puts the average SDR base at £30,000, in a typical range of £25,000 to £36,000, plus around £9,000 a year in commission and bonus. Add the on-costs and year one looks like this:

• Base salary: £30,000 (Glassdoor UK average).
• Commission and bonus: about £9,000 (Glassdoor UK average).
• Employer’s National Insurance: about £5,100, at 15% of pay above £5,000 a year (HMRC, 2026 to 2027).
• Workplace pension: about £1,000, at the 3% employer minimum on qualifying earnings (gov.uk).
• Recruitment fee: about £4,500 to £6,000, at 15% to 20% of base (Mason Bedford). Flowd puts it higher, at 20% to 25% of first-year pay.
• Tools, equipment and onboarding: about £6,500 (Flowd: £5,000 for tech and equipment, £1,500 for training).

That comes to roughly £55,000 to £60,000, depending mostly on the recruitment fee and commission. For comparison, UK agency ORRJO puts a fully loaded SDR at £45,000 to £65,000 a year, and Flowd, on a higher base and commission, at £62,000 to £85,000.

What does outsourced outbound cost?

Outsourced outbound is billed monthly, typically at £3,000 to £10,000 a month in the UK. There’s no recruitment fee or National Insurance on top, and many fees include the tools. The published figures:

• Sopro says its pricing starts at around £3,000 a month, with no minimum contract.
• ORRJO’s 2026 comparison puts UK agencies at £3,500 to £10,000 a month.
• Flowd’s managed programmes start at £4,000 to £5,000 a month (its page gives both), covering research and data, strategy, copy, deliverability, campaign management and inbox handling.

That fee buys very different things. At the low end it can mean volume and spray-and-pray; at the high end, a properly built programme. For how agencies structure the fee, and the costs outside it, see our guide to outsourced SDR pricing.

In-house SDR vs outsourced outbound: the full comparison

Outsourced outbound usually wins on speed and hiring risk, and in-house wins on control. On cost, it depends on what you buy: the entry end costs less than a hire, while a dedicated programme can cost more. What often tips it is how much of the work you can see.

What are the pros and cons of outsourcing SDRs?

Outsourcing your SDRs trades some day-to-day control for speed and less hiring risk.

The pros

• Up and running in weeks, because the team is already ramped.
• One monthly fee, with no recruitment fee or National Insurance.
• No single hire to lose, so one resignation doesn’t reset your pipeline.
• Less to manage: the provider runs the day-to-day.

The cons

• Less control of the message, unless the partner writes in your voice and runs it past you.
• Visibility varies: many agencies report a meeting count, not the messages, lists and replies behind it.
• Price tells you little. At the low end, the fee can buy volume and junk meetings that burn your reputation.
• Product depth takes time. With long sales cycles or technical buyers, an outside team needs time to learn your product.

None of the cons is fixed. Each is a question to ask before you sign: whose voice is it, what will you see, and whose conversations are they?

How long until each starts booking meetings?

A new SDR takes months to get going. UK agency Flowd puts it at around three months, citing The Bridge Group’s 2025 average, and often longer for complex sales, against two to four weeks for an outsourced team that’s already ramped.

Those first months go on learning the product, the market and the message, building lists and finding their feet. You pay the full cost while they do.

Speed isn’t the whole story, though. A fast agency booking junk meetings is worse than none: it burns your calendar, your reputation and the prospects it touches.

What are the hidden costs of an in-house hire?

The salary is the cost you can see. The hidden ones are your management hours, the ramp months you pay for before results, the gaps when they’re off or leave, and the restart if it doesn’t work out.

And the biggest problem I’ve seen in sales? Reps get hired, handed a target and left to figure it out. No process, no support and no real plan for how they’re supposed to win.

When they don’t hit the number, it’s “bad hire”. It’s rarely the person. More often the business wasn’t ready for them, and then it’s lose-lose: they fail, you start again, and the cycle repeats.

When is in-house right, and when is outsourced?

In-house is right when outbound is core to your business for the long term, a rep needs to live and breathe your product (long sales cycles, technical buyers), and you have a proven playbook and the time to manage them. Outsourced is right when you need speed, want less risk, or aren’t ready to hire yet.

Before you hire, ask yourself two questions. Are you clear about what you expect, and what support is on offer? And are you ready for this hire, with the time, the resources and the process to give them what they need to succeed?

Outsourcing has a failure mode too. Many agencies run a black box: lists you never see, sequences in their voice, replies you only hear about.

Can you get the best of both?

Yes. A partner can do the outbound for you and still show you all of it: the targeting, the messages, every reply and every number. Outreach starts in weeks.

That’s why Chris May and I built JumpLead. We run your outbound as an outsourced SDR service, part of your team and in your name.

Nothing goes out without your OK, and the conversations, replies, meetings and numbers are yours. If you need the sales process built too, that’s what fractional sales leadership adds.

Outsourcing doesn’t always win. But don’t gamble on a hire before you’re ready, and don’t sign up for outreach you can’t see. Build the foundation first.
