In-house vs outsourced customer service: the real cost

Key takeaways

In-house vs outsourced customer service is mostly a question of hours. Covering 68 hours a week in-house needs about two full-time hires, roughly £70,000 a year with overheads and management. Outsourcing the same hours at an indicative £12–£15 per hour costs about £44,500–£55,000, with holiday and sickness cover included.

• In-house: about £70,000 a year to staff 68 hours a week with two hires.
• Outsourced: about £44,500–£55,000 for the same hours, cover included.
• In-house: best for complex, high-value or relationship-led queries.
• Outsourced: best for routine volume, extended hours and peaks.

How does outsourced customer service differ from in-house?

In-house customer service is run by your own employees, managed by you. Outsourced customer service is delivered by a provider's team, working in your systems and to your written process, against agreed service levels. The customer should not be able to tell the difference; the business sees it in cost, cover and how quality is managed.

What does in-house customer service cost?

Staffing 8:00 to 20:00 on weekdays and 9:00 to 17:00 on Saturdays is 68 hours a week, about 3,536 hours a year. Two full-time agents on £26,000 cost about £59,500 a year in employment costs and deliver about 3,480 worked hours. Add overheads of about £7,200 and management of about £3,700, and the total is roughly £70,400.

That still leaves gaps at lunch and during overlapping holidays, and no one to absorb a busy Monday.

What does outsourced customer service cost?

At an indicative £12–£15 per hour for a managed offshore team, 3,536 hours cost about £42,400–£53,000 a year. Add about 1 hour a week of your own oversight, £2,080, and the total is about £44,500–£55,100. Recruitment, training, supervision, quality checks and cover sit inside the rate.

That is a saving of about £15,000–£26,000 a year, or 22% to 37%, on this example.

Is outsourced customer service lower quality?

Not when it is set up properly. Quality depends on a written process, good training, supervision and a scorecard reviewed monthly. A managed team with quality sampling is often more consistent than a small in-house team without one. Quality drops when a provider is given no process and nobody measures the result.

When should customer service stay in-house?

Keep it in-house when service is your main differentiator, when most contacts need product expertise or judgement, or when volumes are small and steady enough that one person is fully used. Luxury, high-ticket and highly technical products often fall here.

When is outsourcing customer service the better choice?

Outsource when you need longer hours than one person can cover, when volume swings with seasons or campaigns, or when routine questions take most of the team's time. A hybrid often works best: the provider handles first-line contacts and out-of-hours, your team handles escalations.

What about customer data?

An outsourced provider handling customer data is a processor under UK GDPR, so you need a written processor contract, and an offshore team needs a valid transfer safeguard. Give individual logins and only the access needed. These are routine steps, not blockers.

How do you move customer service over without disruption?

Move one channel or one contact type first, usually email or chat, while the in-house team keeps the rest. Give the provider your templates, tone guide and the 20 most common questions with answers, and have the in-house lead review a sample of replies daily for the first two weeks. Add phones and weekends once quality matches the baseline.

• Week 1 to 2: one channel, daily sample reviews.
• Week 3 to 6: add contact types and extended hours.
• Week 7 onwards: monthly scorecard and weekly escalation review.

• A BPO transition plan for the first 90 days

What does this look like in practice?

A pattern we see in UK e-commerce brands: two in-house agents cover weekdays, and weekend messages wait until Monday. Moving first-line email and chat to a managed team with weekend cover, and keeping one in-house lead for escalations, lowers cost and removes the Monday backlog.
