Appointment setting: in-house vs agency cost example

What to take away

In-house appointment setting costs more than base salaryemployer National Insurance, pension, tools and management time all add to the bill.
An agency usually charges a retainer or a fee per meeting, so you pay for output rather than capacity.
Whether the lower-cost option is also better value depends on meeting volume, average deal size and how quickly you can hire.
Compliance with the Data Protection Act 2018 and the CAP code applies whether you build or buy.

In-house costs: salary and overhead

Start with salary. The ONS Annual Survey of Hours and Earnings 2024 puts median full-time earnings at £37,430, and the release of 22 October 2026 puts the April 2026 median at £40,911. An SDR base often sits below that, but you still pay employer National Insurance at 15% from April 2025, according to HMRC.

Pension adds more. The Pensions Regulator sets the total minimum contribution at 8%, of which the employer pays at least 3% of qualifying earnings. Add a CRM seat, a dialler and data, and the monthly cost rises again.

Management time is the hidden line. Someone must coach the setter, review call recordings and fix list quality. That is usually a sales manager or founder, not a free resource.

In-house teams must follow the Data Protection Act 2018 when they process prospect data for marketing calls. That means a lawful basis, clear privacy information and a way to honour objections.

How agencies charge for appointment setting

Agencies price in three main ways: a monthly retainer, a fee per meeting, or a hybrid. Each shifts risk. A retainer buys capacity; a per-meeting fee ties payment to booked calls.

In-house vs agency cost structure

In-house

Base pay: Salary, NIC, pension
Tools: CRM, dialler, data
Management: Sales manager time
Risk: Recruitment and turnover
Payment trigger: Monthly payroll

Agency

Base pay: Included in fee
Tools: Usually included
Management: Account manager
Risk: Replacement policy
Payment trigger: Retainer or per meeting

The key number is cost per meeting, not cost per lead. Ask what counts as a qualified meeting and what happens when a prospect cancels. Our guide to pay per appointment pricing explains how UK agencies structure those fees.

Before signing, check the agency's filing history and accounts at Companies House. That shows whether the company is established and how it has grown.

A worked example: cost per meeting

Use the ONS ASHE 2024 median salary of £37,430. Employer National Insurance at 15% on earnings above the £5,000 secondary threshold adds £4,864.50. Pension at 3% adds about £1,123. The base employment cost is £43,418 a year.

Assume that setter books 8 meetings a month. That is 96 a year. Divide £43,418 by 96 and the in-house cost is about £452 per meeting, before tools and management.

At an illustrative agency fee of £500 per meeting, the same 8 meetings cost £4,000 a month, or £48,000 a year. That exceeds the £43,418 base employment cost, before in-house tools and management, while the agency carries recruitment, tools and management risk.

At illustrative fees of £400 and £600 per meeting, the agency cost would be £38,400 and £57,600 a year respectively. Your actual break-even depends on fully loaded in-house costs.

When in-house makes sense

Build in-house when you have steady meeting volume, a clear script and a manager who can coach. You also need a clean data process that follows UK marketing rules.

In-house suits complex products that need deep discovery. The setter learns the product over time, which can lift meeting quality. That advantage fades if turnover is high.

When an agency makes sense

An agency makes sense when you need meetings now, lack a sales manager, or want to test a new segment. You pay for booked calls and keep your headcount flexible.

Agencies should know the CAP code rules on misleading claims and consent. Ask to see their call scripts and opt-out process.

The main risk is quality drift. Set a clear definition of a qualified meeting, review recordings weekly and hold the agency to replacement meetings for no-shows.

Common questions

How much does an in-house SDR cost in the UK?

The ONS ASHE 2024 median full-time salary is £37,430. Employer National Insurance at 15% and pension at 3% push the base cost to about £43,418 before tools.

Is an appointment setting agency cheaper than hiring?

Not always. At 8 meetings a month, an in-house setter costs about £452 per meeting. An agency at £500 per meeting costs more, but you avoid recruitment and management time.

What is the break-even point for agency vs in-house?

With the example's figures, the in-house baseline is about £452 per meeting before tools and management, so £452 is the illustrative break-even agency fee. Once tools and management are included, the in-house break-even fee is higher.

Can an agency guarantee meetings?

No. Any guarantee should define a qualified meeting, a replacement policy and a time limit. Read the contract before you sign.
