- The true cost of an in-house SDR is salary plus employer costs, tooling, data, sending infrastructure, management time, compliance oversight and the months of ramp before they produce.
- A managed signal-triggered service swaps those lines for one fixed monthly fee, launches in weeks and can be stopped month to month, but gives you less direct control and no internal capability at the end.
- Compliance risk is now a real cost line: the ICO can fine PECR breaches up to £17.5 million or 4% of global turnover, and Google and Microsoft enforce strict sender rules.
- Hiring in-house wins when outbound is already proven, you have someone to manage the role, and the job needs phone work, events or deep account relationships.
- Many firms start with a managed service to prove the channel, then hire an SDR to handle replies and relationships once they know which segments convert.
For most UK financial services firms without a proven outbound playbook, a managed signal-triggered service is the lower-risk way to start, because you pay one fixed monthly fee instead of carrying salary, tooling, data, ramp time and compliance oversight before the first meeting lands. Hiring an SDR wins when outbound already works, someone has time to manage the role, and the job needs phone work, product depth or relationships an outside team cannot hold.
The comparison at a glance
| Criteria | In-house SDR | Generalist SDR agency | Specialist managed outbound (signal-triggered) |
|---|---|---|---|
| Cost | Salary, employer costs, commission, tools, data, domains, manager time | Monthly retainer, often with setup fees and minimum terms | Fixed monthly fee covering data, research, copy and sending |
| Time to results | Recruitment, onboarding and ramp, usually months | Weeks, depending on onboarding | Weeks. Rept launches campaigns within 14 days |
| Control | Full, day to day | Shared, often limited visibility into lists and copy | Shared, with sign-off on targeting and messaging |
| Compliance | You own PECR, suppression, LIA and template sign-off | Varies widely, check carefully | Should be built in and documented |
| Your effort | High: hiring, coaching, QA, tooling admin | Medium: briefing and quality checks | Low: briefing, approvals, taking the meetings |
| What you keep | Skills and knowledge in your team | Usually little | Usually data and learnings, check the contract |
| Exit cost | Notice, possible redundancy, re-hire | Contract terms | Month to month if the provider allows it |
What an in-house SDR really costs over 12 months
Most founders compare salary with an agency fee. That is the wrong comparison. The salary is often the smaller part of the risk.
Build your own fully loaded model with these lines:
- Base salary and commission. Commission plans for outbound roles need designing, policing and adjusting.
- Employer costs. National Insurance, pension contributions, holiday cover and benefits.
- Recruitment. An agency fee, or the hours you and a colleague spend screening and interviewing.
- Tooling. CRM seat, LinkedIn Sales Navigator, a sequencing tool, email verification.
- Data. A contact data subscription, plus someone keeping it clean and suppressed.
- Sending infrastructure. Separate domains, inboxes and warm-up so cold email never touches your main domain.
- Management time. Daily coaching, call reviews, copy reviews. This comes out of a senior person's week.
- Compliance oversight. Template sign-off, PECR training, a legitimate interests assessment, suppression lists and an audit trail.
- Ramp. You pay the full cost for months while output builds.
- Churn. If the hire leaves, you pay the ramp cost again and lose whatever they learned.
Run the model honestly and the first-year cost per qualified meeting is usually far higher than the salary suggests, because the first few months produce little. We walk through the funnel maths in the real maths behind B2B financial services outbound.
Option 1: hiring an in-house SDR
Strengths
- Control. You see every list, every email and every call. You can change direction the same afternoon.
- Product depth. A good SDR learns your credit appetite, underwriting criteria or product nuances over time and qualifies better because of it.
- Multi-channel by default. They can pick up the phone, attend events and nurture warm relationships, which suits relationship-led sales.
- Capability you own. The knowledge stays in the business, as long as the person does.
Weaknesses
- Slow to value. Recruitment, onboarding and ramp come before consistent output.
- Single point of failure. One person, one set of habits. Sickness, holiday or resignation stops the pipeline.
- Hidden infrastructure work. Domains, warm-up, deliverability monitoring and data hygiene are specialist jobs. Most SDRs are not hired to do them and do them badly.
- Compliance falls on you. In a regulated firm, every template needs checking so it does not become a financial promotion, and every contact needs a lawful basis.
- Research does not scale. One person can only properly research a limited number of companies a day, so quality and volume pull against each other.
Option 2: a generalist SDR agency
These firms run outbound for many sectors. Some are very good. The risk is that financial services is treated like SaaS.
Strengths
- Fast to start, with tools and people already in place.
- Often include calling, which a pure email service may not.
- Useful if your offer is simple and your buyers are not in a regulated niche.
Weaknesses
- Sector fluency varies. Writing to a finance director about invoice finance or to a merchant about payment terms needs different language from software sales.
- Compliance is uneven. Ask who approves copy, how they avoid financial promotions, what their PECR basis is and where suppression lists live. Vague answers are a warning.
- Volume over relevance. Many agencies are paid on activity or meetings booked, which can push towards poorly qualified meetings that waste your sales team's time.
- Lock-in. Minimum terms and setup fees make a failed test expensive.
Option 3: a specialist managed, signal-triggered service
This is the model Rept runs. Instead of mailing a static list, the service watches for buying signals and writes to companies when something has changed. Rept tracks ten: sales hiring, job-posting surges, funding rounds, Companies House charges, filed accounts, new paid advertising, leadership hires, market expansion, tech-stack changes and industry news.
Strengths
- Cost is fixed and visible. Rept's Growth plan is £1,350 + VAT a month and Enterprise is £2,500 + VAT a month, with an £80 onboarding fee, month to month. Data, research, copywriting and sending domains are included.
- Fast start. Campaigns launch within 14 days, so you learn whether the channel works in weeks rather than after a hiring cycle.
- Relevance at volume. Each email is written from research on that company, which is hard for one SDR to sustain.
- Deliverability handled. Sending runs from separate warmed-up domains, which matters now that Google requires bulk senders to Gmail to have SPF, DKIM and DMARC, one-click unsubscribe and a spam complaint rate under 0.3% (Google sender guidelines). Microsoft introduced the same requirements for Outlook in May 2025.
- Evidence from the sector. Across 150+ financial services clients Rept has generated 100,000+ high-intent leads, with a 29.4% average positive reply rate. WSC Finance has had 156,800+ emails sent, a 25.6% positive reply rate and 243 qualified opportunities since July 2025. Growth Business Finance ran 12,896 sequences at an 18.2% positive reply rate for 80 qualified leads. These are past client results, not a forecast for your firm.
Weaknesses
- Less hands-on control. You approve targeting and messaging but do not write every email yourself.
- Email and LinkedIn only. If your sale depends on cold calling or events, you still need a person for that.
- You still have to show up. Interested replies are handed to you. If nobody follows up quickly, the work is wasted.
- No internal skills built. When you stop, the engine stops. You keep the learnings, not a trained person.
Compliance: the cost line most models leave out
For a regulated firm, a badly run outbound programme is not just wasted spend. It is regulatory exposure.
Under the Data (Use and Access) Act, the ICO can fine PECR breaches up to £17.5 million or 4% of global turnover, whichever is higher. The previous maximum was £500,000. That changes the maths on cutting corners.
Whatever option you choose, check for:
- Corporate-subscriber targeting under PECR, not sole traders or personal addresses.
- An opt-out on every email and permanent suppression lists, so someone who says no is never contacted again, even if the campaign or the SDR changes.
- A legitimate interests assessment on file.
- No financial promotions in cold email. The FCA requires promotions to be clear, fair and not misleading and applies product-specific rules (FCA guidance on financial promotions). The safe approach is for the cold email to open a conversation, never to promote rates, returns or product terms.
With an in-house SDR, all of this is your job. With a provider, it should be in writing before you sign.
A note for insurance brokers and wealth firms
Insurance and wealth businesses often assume outbound needs a team of SDRs. In practice, the bottleneck is usually finding the right moment, not making more calls.
Signals do much of that work. A company that has just raised funding, opened new premises, hired a leadership team or expanded into a new market often has new cover, key person or employee benefit questions. A business filing accounts that show strong growth may be ready for a wealth conversation with its owners. A managed service can watch for those triggers across your whole target market and write to each firm about its own situation, while your brokers or advisers handle the replies. Rept's best positive reply rate in wealth is 50%, and in payment gateways it is 60%, which shows how much timing and relevance matter in those sectors.
The compliance point is sharper here: insurance and investment products sit squarely within FCA promotion rules, so cold emails should never quote products, premiums or performance.
Decision checklist: when hiring in-house actually wins
Hire an SDR if most of these are true:
- Outbound is already proven. You know which segments, signals and messages produce meetings.
- Someone will manage the role. A named person has several hours a week to coach and review.
- The job is more than email. Phone, events and account nurturing are a large part of the work.
- Your market is narrow. A small list of named accounts that needs deep, long-term relationship building.
- Compliance is ready. You have a process for template sign-off, suppression and lawful basis.
- You can absorb churn. Losing the hire after a year would not stall the business.
If fewer than half are true, a managed service is usually the better first step.
Who each option suits
- In-house SDR: established firms with a proven playbook, a sales manager with capacity, and relationship-led or phone-heavy sales.
- Generalist SDR agency: firms with a simple, unregulated-feeling offer who want calling included and can vet compliance themselves.
- Specialist managed service: brokers, lenders, debt recovery firms, fintechs, payments businesses, wealth and insurance firms that want pipeline quickly, need compliance built in, and would rather not hire and manage outbound in-house yet.
- Hybrid: firms that start with a managed service to prove the channel, then hire someone to handle replies, calls and relationships. This is common and often the most sensible route. For a deeper look at what a well-run programme produces, see lessons from 942,508 emails.
Rept runs this as a fully managed service: we map your target market, research every company for signals, write each email from that research, send from separate warmed-up domains and hand interested replies straight to you.
