B2B lead generation cost in the UK comes down to one number: what you pay for each qualified meeting. An in-house SDR costs around £47,000 a year before management time and most tools, and in year one that typically works out at £450 to £700 per meeting. Outsourced and AI-led outbound usually lands lower per meeting, with less risk, but only if the meetings are genuinely qualified.
This article builds the in-house cost from GOV.UK rates and published benchmarks, line by line, then compares it with agencies and AI-led outbound. You can swap in your own numbers at every step.
01Why cost per meeting is the only B2B lead generation cost that matters
Most budgeting conversations start with the wrong number. A £1,000 retainer sounds cheap and a £30,000 salary sounds manageable, but neither tells you what you are buying.
What you are buying is a conversation with the right person at the right company. So the useful unit is cost per qualified meeting: total spend divided by meetings that actually happened with people who match your ideal customer profile.
Three things distort that number, and every option below handles them differently:
- Ramp time. How many months you pay before meetings arrive at full rate.
- Attrition. How often you start again from zero.
- Qualification. Whether a "meeting" means a 15-minute intro with anyone who picked up, or a held call with a decision-maker in your target market.
Pin down the third one before you compare quotes. A cheap meeting with the wrong person is the most expensive meeting you will ever book.
02What an in-house SDR really costs in the UK
Start with salary. Payscale puts the average UK SDR base salary at £30,002 in 2026, with most falling between £23,000 and £44,000.
Then add the costs that never appear in the job advert.
The line-by-line build
| Cost line | Annual cost | How it is calculated |
|---|---|---|
| Base salary | £30,000 | Payscale UK average, rounded |
| Commission or bonus | £10,000 | Our assumption: a modest variable on top of base |
| Employer National Insurance | £5,250 | 15% on earnings above £5,000 |
| Employer pension | £1,013 | 3% of qualifying earnings above £6,240 |
| LinkedIn Sales Navigator Core | £960 | £959.88 a year, before VAT |
| Subtotal | £47,223 | Before data tools, management and recruitment |
The National Insurance line uses the current HMRC rates: 15% above a secondary threshold of £5,000 a year. If you can still claim the £10,500 Employment Allowance, it softens this, but most growing firms use it up quickly. The pension line uses the statutory 3% employer minimum on earnings between £6,240 and £50,270. The licence is LinkedIn's published UK price for Sales Navigator Core.
The costs the subtotal leaves out
The £47,223 is the floor, not the total. On top of it you still need:
- A data and enrichment tool for verified emails and phone numbers.
- A sequencing tool for email cadences and reply tracking.
- Management time. The Bridge Group's research finds an average of 6.4 SDRs per leader. If you hire one SDR, you are buying a slice of a sales manager or, more often, a slice of the founder.
- Recruitment. Agency fees, or your own time screening and interviewing.
- Equipment, onboarding and training.
Get real quotes for your stack. In our experience the tooling alone is rarely trivial once you add data credits, and management time is the line founders most often forget to price.
03How many meetings an SDR actually books
Cost is only half the sum. The other half is output, and here the best public data comes from The Bridge Group's 2025 SDR Models and Metrics Report, which surveyed 351 companies. It is weighted towards US tech firms, so treat it as a benchmark, not a promise for the UK.
Two of those numbers should change how you budget. Only 60% of SDRs hit quota, the lowest the study has recorded. And median annual attrition is 40%, which includes promotions as well as people leaving. Average tenure is 1.9 years.
A worked year-one example
Here is the year-one maths for one new hire, using the Bridge Group benchmarks:
- Months 1 to 3 (ramp): half quota, so 5 meetings a month, 15 in total.
- Months 4 to 12: full quota of 10 a month, 90 in total.
- Best case: 105 meetings in year one.
- Realistic case: they ramp at 4 a month and settle at 8 (80% of quota, given 40% of reps miss it). That is 12 plus 72, so 84 meetings.
Now divide the cost by the output:
| Scenario | Annual cost | Meetings | Cost per meeting |
|---|---|---|---|
| Best case, subtotal only | £47,223 | 105 | £450 |
| Realistic, subtotal only | £47,223 | 84 | £562 |
| Best case, plus £11,000 of management time | £58,223 | 105 | £554 |
| Realistic, plus £11,000 of management time | £58,223 | 84 | £693 |
The £11,000 assumes roughly one-sixth of a manager who costs £66,000 fully loaded. Replace it with your own figure.
None of this includes the months spent recruiting before day one, or the cost of starting again if the hire leaves. With 40% median attrition, that second risk is not an edge case.
An SDR is not a cost, it is a bet on one person ramping, staying and hitting quota. Sometimes that bet is right. Just price it honestly before you place it.

04What a B2B lead generation agency costs
Agencies sell the same output without the hiring risk. They price it in three common ways.
Retainer
A fixed monthly fee for a defined scope: list building, messaging, sequencing and reply handling. You carry the risk of a slow month, but the agency is paid to build a system rather than chase volume. It is a common model for managed outbound.
Pay per meeting
You pay only for meetings booked or held. It looks safe, but it rewards volume over fit. If you go this way, write the qualification criteria into the contract: job titles, company size, sector, and whether the meeting has to be held, not just booked.
Hybrid
A lower retainer plus a fee per qualified meeting. Often the fairest split, as long as "qualified" is defined in writing.
Our published pricing, as one example
We publish our B2B lead generation packages, so here is how they convert to cost per meeting using the typical ranges we state. These are typical ranges, not promises.
| Package | Price | Typical meetings a month | Implied cost per meeting |
|---|---|---|---|
| Pilot | £1,000 one-off | Proof, not volume | Not applicable |
| Signal | £1,000 a month | 4 to 8 | £125 to £250 |
| Growth | £2,500 a month | 8 to 15 | £167 to £313 |
| Engine | £4,500 a month | 15 to 25 | £180 to £300 |
The Pilot is a 30-day proof sprint on 500 scored contacts, credited against month one if you continue. It exists so you can test the cost per meeting in your own market before committing to a retainer.
Whichever agency you talk to, ask for the same sum: price divided by the meetings they typically deliver for firms like yours. If they will not give you a range, that tells you something.
05What AI-led outbound costs, and where it breaks
The third option is to build outbound yourself on AI tooling: enrichment, scoring, AI-written personalisation and automated sequences, run by one person who owns the system.
On paper it is the cheapest route. In practice the cost moves from salary into setup time and expertise. The parts that go wrong are not the AI ones:
- Targeting. AI personalisation on a bad list just produces well-written messages to the wrong people.
- Deliverability. Sending volume from a fresh domain without proper authentication and warm-up lands you in spam, and the damage outlasts the campaign.
- Compliance. The ICO's PECR guidance says you can email corporate bodies without prior consent, but sole traders and some partnerships are treated as individuals and need consent. UK GDPR still applies to the personal data you process. Scraped lists rarely respect that line.
- Reply handling. A positive reply that waits two days is a lost meeting. Someone has to own the inbox.
If you have someone who already understands data, scoring and deliverability, building in-house can make sense. We set out the full architecture in how we build B2B outbound revenue systems, and our AI automation and training work exists for teams that want to build it and run it themselves.
06How to choose the right model for your budget
Here is the comparison on the factors that actually decide it.
| Factor | In-house SDR | Agency or managed service | DIY AI-led outbound |
|---|---|---|---|
| Year-one cost per meeting | Highest once ramp and management are counted | Lower and predictable | Lowest on paper, highest setup effort |
| Time to first meetings | Recruitment plus about 3 months ramp | Weeks | Weeks to months, depending on skills |
| Attrition risk | High: 40% median a year | Carried by the provider | Concentrated in one person |
| Product knowledge on calls | Strongest over time | Depends on the brief | Depends on who books |
| Who owns the data | You | Check the contract | You |
What I would actually do, depending on where you are:
- Under 10 meetings a month needed, no sales manager: outsource. Start with a short paid pilot, measure cost per held meeting, then decide.
- Proven offer, 15 or more meetings a month needed, a manager in place: hire SDRs, but keep a managed channel running while they ramp so pipeline does not dip.
- Strong ops person in-house and a tight ICP: build AI-led outbound yourself, and budget properly for data, deliverability and compliance.
Before you sign anything, work out what one meeting is worth. If one in ten meetings closes and the average deal brings £20,000 in gross margin, each meeting is worth about £2,000 to you. That number tells you how much you can afford to pay, and makes every quote easy to judge.

07Frequently asked questions
How much does B2B lead generation cost in the UK?
It depends on the model. An in-house SDR costs roughly £47,000 a year in salary, commission, employer National Insurance, pension and a LinkedIn licence before management time and other tools. Agencies and managed outbound services typically charge a monthly retainer, a fee per meeting, or a mix of both. Compare them on cost per qualified meeting, not on the headline price.
What is a good cost per meeting for B2B outbound?
There is no single benchmark, because it depends on deal size and how strictly a meeting is qualified. Work backwards from your numbers: if a meeting turns into a deal one time in ten and the average deal is worth £20,000 in gross margin, each meeting is worth about £2,000 to you. Anything well below that is worth buying, provided the meetings are genuinely qualified.
Is it cheaper to hire an SDR or use a lead generation agency?
In our view, for firms that need fewer than 10 meetings a month, an outsourced or AI-led service is cheaper per meeting in year one, because you avoid the three-month ramp, recruitment and attrition risk. An in-house SDR team starts to make more sense when you need sustained volume, deep product knowledge on calls, and have a manager to run it.
How long does it take a new SDR to become productive?
The Bridge Group's 2025 SDR report puts average ramp time at 3.0 months, the lowest it has recorded since 2010. Add the time it takes to recruit, and in our experience you should plan for several months between deciding to hire and seeing a full month of meetings.
Is cold email to businesses legal in the UK?
Under PECR you can send marketing emails to corporate bodies such as limited companies and LLPs without prior consent, as long as you identify yourself and offer an opt-out. Sole traders and some partnerships are treated as individuals and need consent. UK GDPR still applies to the personal data you process, so you need a lawful basis and a clear privacy notice.
