Most B2B lead generation agencies charge $3,000-$20,000 per month on retainer (£2,000-£6,000+ in the UK). Pay-per-appointment models run $150-$500 per booked meeting, and pay-per-lead pricing ranges from $30 to $800 per lead depending on qualification stage. Here is what drives those numbers — and the hidden costs quotes leave out.
| Pricing Model | Typical Range | What You Get | Best For |
|---|---|---|---|
| Monthly retainer | $3,000-$20,000/mo (£2,000-£6,000+ UK) | Managed service: strategy, data, copy, sending infrastructure, campaign management, reporting | Companies with a proven offer that want a partner owning the outbound motion |
| Pay-per-appointment | $150-$500 per booked meeting (£100-£400 UK) | Booked meetings on your calendar; qualification standards vary widely by vendor | Teams that want output-priced budgeting and can enforce qualification criteria in writing |
| Pay-per-lead | $30-$800 per lead depending on stage | Contact-level leads (MQL through HQL), often via content syndication; earlier-stage than booked meetings | Marketing teams with hard MQL quotas and nurture capacity |
| Productized subscription | $397-$1,000/mo | Single-channel service (usually LinkedIn) with standardized deliverables and limited strategy | Small businesses testing outbound for the first time |
| In-house SDR (benchmark) | $8,000-$12,000/mo fully loaded (£5,000-£8,000 UK) | Salary, benefits, data subscriptions, sending tools, management time — before a single meeting is booked | The number every agency quote should be judged against |

Two agencies quoting $4,000/mo can be selling completely different products. These five factors explain the spread — and are the questions to ask before comparing any quotes.
Email-only programs sit at the lower end of retainer ranges. Adding LinkedIn typically raises the fee moderately; adding phone raises it substantially, because calling requires paid humans per conversation while email scales with infrastructure. Multi-channel retainers from firms like Belkins run $4K-15K/mo, versus email-led retainers like Growleady's flat $5,000/mo (from £4,000/mo in the UK).
A quoted retainer can hide $500-$2,000/mo of pass-through costs: contact data subscriptions, sending domains, inboxes, warmup tools, and sequencing software. Some agencies include everything; others bill tooling separately. Always ask what happens to domains and data when you leave — infrastructure you don't own walks out the door with the agency.
Booking meetings with mid-market marketing managers costs less than booking C-suite buyers at enterprise accounts. Harder ICPs mean more research per contact, smaller sendable lists, more personalization, and therefore higher retainers or higher per-meeting prices. If an agency quotes the same price for 'VP+ at Fortune 500' as for 'founders of 10-person startups', they haven't thought about your ICP.
In pay-per-appointment pricing, the qualification bar is the real price. A $200 meeting that no-shows or was never a fit costs more than a $500 meeting that closes. Define in writing what counts as qualified — title, company size, explicit interest, showed up — before comparing per-meeting quotes.
Agencies discount for 6-12 month commitments because outbound compounds: months one and two build infrastructure and learning, months three onward harvest. That logic is genuine, but never let it lock you into a nonperforming engagement — prefer month-to-month or 90-day initial terms with clear performance checkpoints.
The honest benchmark for any agency quote is the fully loaded cost of doing it yourself. One in-house SDR costs $8,000-$12,000 per month once you count salary, benefits, contact data subscriptions, sending and sequencing tools, and the management time to coach them — £5,000-£8,000 per month in the UK. They take three to six months to ramp, and if they leave, the learning leaves with them.
A specialist agency retainer at $3,500-$6,000/mo buys a team that is already ramped: strategist, copywriter, data researcher, and deliverability engineer, plus infrastructure that took years to refine. That is why outsourcing usually wins for the first 6-18 months of an outbound motion. In-house wins later, at scale — when outbound is proven, volume justifies headcount, and you want the capability compounding inside your own company rather than a vendor's.
The mistake is comparing an agency retainer to an SDR's salary alone. $60K of salary is $100K+ of real cost before the first meeting is booked.
Pass-through tooling and data fees. Contact data, sending domains, inboxes, warmup, and sequencing software commonly add $500-$2,000/mo when billed separately. Ask for the all-in monthly number in writing.
Setup and onboarding fees. One-time fees of $1,000-$5,000 are common for infrastructure builds. Not unreasonable — domain and inbox setup is real work — but they change the math on short engagements.
Who owns the infrastructure. If the agency owns the sending domains, mailboxes, and lists, leaving them means starting outbound from zero. Negotiate ownership or transfer rights up front.
Compliance shortcuts. The cheapest quote often skips the unglamorous costs: verified data, warmed domains, CAN-SPAM/PECR-compliant sending. Those shortcuts surface later as burned domains and spam-folder placement — a cost no invoice shows.
Most B2B lead generation agencies charge $3,000-$20,000 per month on retainer (£2,000-£6,000+ in the UK), depending on channels, volume, and target seniority. Pay-per-appointment models run $150-$500 per booked meeting (£100-£400 UK). Pay-per-lead pricing ranges from $30 for early-stage content-syndication leads to $800 for highly qualified, sales-ready leads. Productized single-channel services start around $397/mo. Growleady charges a flat $5,000/mo in the US and from £4,000/mo in the UK, with data, infrastructure, copy, and reporting included.
It depends entirely on lead stage and deal size. Content-syndication MQLs commonly cost $30-$100. Sales-qualified leads from genuine outbound typically cost $150-$500. A fully booked, show-up meeting with a decision-maker at a target account can reasonably cost $300-$800 when average contract values are $20K+. The only universal rule: work backwards from deal economics. If your customer lifetime value is $50K, a $500 qualified meeting is cheap; if your ACV is $2K, it is ruinous.
Usually, yes — at least to start. One in-house SDR costs $8,000-$12,000 per month fully loaded (salary, benefits, data subscriptions, sending and sequencing tools, management time) — £5,000-£8,000 in the UK — and takes 3-6 months to ramp. A specialist agency retainer at $3,500-$6,000/mo delivers a full team (strategist, copywriter, data researcher, deliverability engineer) that is already ramped. In-house wins later, at scale, when outbound is proven and you want the knowledge compounding inside your own team.
Five variables drive the spread: (1) channels — phone-inclusive programs cost more than email-led ones; (2) who pays for data and sending infrastructure; (3) target difficulty — enterprise C-suite ICPs cost more to book than SMB founders; (4) team seniority — senior-led boutiques charge more than offshore volume shops; (5) what 'lead' means — an MQL from content syndication and a booked C-suite meeting are different products separated by 10x pricing. Quotes are only comparable after you normalize all five.
A complete retainer includes: ICP research and list building with verified contact data; sending infrastructure (separate warmed domains, inbox rotation, SPF/DKIM/DMARC setup); copywriting and A/B testing; campaign management and reply handling; compliance documentation (CAN-SPAM in the US, PECR and UK GDPR in the UK); and transparent reporting. Treat quotes that exclude data or infrastructure as incomplete — those pass-throughs commonly add $500-$2,000/mo.
Below roughly $1,000/mo, done-for-you outbound cannot cover the real costs of doing it properly — verified data, warmed infrastructure, and human copywriting — so corners get cut, usually on data quality and sending practices, which puts your domain reputation at risk. The exceptions are productized single-channel services like LinkedIn outreach ($397-$997/mo), which are honest about their narrow scope. If budget is tight, founder-led outreach with a good data tool beats a cheap agency.
Growleady charges a flat $5,000/mo (from £4,000/mo in the UK) with data, infrastructure, copywriting, and reporting included — no pass-throughs, no long-term contracts. Book a call and we'll tell you honestly whether outbound pencils out for your deal size.
