How Much Does an Outsourced SDR Team Cost in the UK?

An SDR (sales development representative) books qualified sales meetings for your closers, and an outsourced SDR team in the UK is priced one of three ways: a fixed monthly fee per rep or programme (rates are rarely published and vary widely by agency), a price per qualified meeting delivered, or an outcome-based contract where the fee is tied to an agreed number of meetings. Sentrama runs the outcome model: clients pay for qualified meetings, with no retainer. The model matters more than the headline figure, and the number that settles the decision is cost per qualified meeting, not cost per head.

What does an outsourced SDR team cost in the UK?

An outsourced SDR team in the UK is priced on a monthly fee, per qualified meeting, or on an outcome-based guarantee, and the model decides who carries the risk. A low monthly fee with no meeting commitment can cost you more per meeting than a higher fee with outcomes attached, because you carry all the delivery risk. Guaranteeing the outcome instead is a commercial risk most UK agencies will not take, and Sentrama takes it because the honest unit of measurement in this market is the meeting. Hours are what retainers sell.

So before comparing quotes, fix the question. The thing being bought is a qualified conversation with your ICP, and every pricing model should be converted into cost per meeting before you judge it. If the proposal on your desk says BDR rather than SDR, the maths transfers directly... the UK market uses the titles interchangeably, and what you are actually buying under a BDR label is the same function.

What does a full-time SDR really cost in-house?

Around £45,000 to £55,000 in year one, for one rep, before a single meeting is booked. The salary is the visible part. The rest hides in employer costs, tooling and time.

Run the maths on a mid-level UK SDR:

Then add time. The Bridge Group's 2025 research puts average SDR ramp at 3.0 months and average tenure at 1.9 years. In practice that means you pay a full quarter's cost before full productivity, and you rerun recruitment and ramp roughly every two years. The same study found only 60% of reps hitting quota... the lowest on record. The in-house route can work. But the true cost is nowhere near the £30,000 on the job advert. There is a fuller model of the in-house maths in Sentrama vs hiring an SDR.

What are the outsourced SDR pricing models?

Outsourced SDR pricing runs on three models, whether the provider calls itself SDR as a service, a fully managed SDR team or done-for-you sales development. The label changes. The commercial structure underneath is one of these:

A retainer pays for effort. An outcome contract pays for results. Agencies that bill retainers for hours are misaligned with the client from the first invoice, which is why Sentrama does not take retainers at all. Every meeting we deliver passes a 14-step quality-control process... a human listens to the call, reads the transcript, then approves or rejects the meeting before the client ever sees it. When the fee depends on the meeting standing up, quality control stops being a marketing line.

Whichever model you are quoted, ask two questions. What is the definition of a qualified meeting in the contract? And what happens commercially when the number is missed? There is a fuller checklist in our guide to choosing a B2B outbound agency.

Why do outsourced SDR prices vary so much?

Because the inputs vary. Four things drive the price of a serious outbound programme, the same four pillars that decide whether outbound works at all: the data (verified, ICP-matched prospects cost more than scraped lists), the strategy (a sharp offer and call reason takes senior work), the technology (dialling infrastructure and outcome tracking) and the humans (senior SDRs cost more than graduates, and book more).

Cheap programmes cut one of those four, and it shows up in the connect rate. Across the Sentrama floor, 25%+ of dials connect to a human. The best published benchmark is Salesfinity's 10.1%, and Gong's sits at 5.4%. That gap is engineered through pickup-scored leads and verified mobiles, and it is the difference between a rep having 15+ real conversations an hour and a rep listening to voicemails. The full dial maths is in how many dials it takes to book a B2B meeting. When you compare two quotes, you are usually comparing two very different machines wearing the same label.

Is it cheaper to outsource SDRs than to hire?

Per meeting, usually yes. Per head, usually no. That is the honest answer, and the maths is simple enough to run yourself.

Take the in-house route: £45,000 to £55,000 in year one. If your rep ramps in three months and books meetings at a typical rate for an internal team, divide the annual cost by the annual meetings and you have your true cost per meeting. Most sales leaders who run this number for the first time find it lands well above what they assumed.

Then price the outsourced route the same way. When a senior rep gets a real conversation, 15 to 25% of those convert to a booked meeting. At Sentrama that machine books 400+ qualified meetings for clients every month, so the cost per meeting is a known, contracted number rather than a hope. An internal hire also buys you things an agency does not: product knowledge that compounds, and a promotion path into closing roles. If you already have the management bandwidth and the infrastructure in place, hiring can be the right call. If you do not, you are building a call centre one seat at a time.

Work out your own SDR cost per meeting

The fastest way to settle hire-vs-outsource is to run your numbers through the SDR Efficiency Calculator. Ten minutes with your own figures gives you a cost per meeting you can put in front of the board.

Run the maths before the market runs it for you. The SDR Efficiency Calculator turns your own dial, connect and conversion numbers into a true cost per qualified meeting.
